SPAN (Switched Port Analyzer) is a feature that allows network traffic from one or more source ports to be mirrored to a destination port for analysis. When configuring SPAN on a Cisco Nexus 5000 Series switch, two characteristics must be considered:

• A SPAN source port can be monitored in multiple SPAN sessions. This means that the same port can send traffic to different destination ports for different purposes or applications.
• A SPAN source port cannot be a destination SPAN port. This means that a port cannot receive traffic from another port that it is already monitoring. This prevents loops and conflicts in the SPAN configuration.

 The QoS policy that controls only vHBA traffic is the Fibre Channel policy. In Cisco UCS, the Fibre Channel policy is specifically designed to manage the quality of service for traffic related to virtual Host Bus Adapters (vHBAs), which are used for Fibre Channel over Ethernet (FCoE) storage networking. This policy ensures that the storage traffic is appropriately prioritized and managed within the system.

Cisco UCS Manager supports various types of authentication mechanisms for enhanced security. Option A (local) refers to the use of locally stored user credentials within the UCS Manager for authentication. Option B (LDAP) indicates that UCS Manager can integrate with LDAP (Lightweight Directory Access Protocol) directories for user authentication, allowing centralized management of user credentials. References: Cisco Data Center Core Technologies source documents or study guide

To set access to Cisco IMC (Integrated Management Controller) and allow logging onto the https://datacenter.local  web page, the correct set of commands is found in option C. These commands will configure the network settings on the Cisco UCS C240 Series Server to enable web access to the Cisco IMC interface. The configuration typically involves setting the correct IP address, gateway, and other network parameters that align with the data center’s network design.

DTLS (Datagram Transport Layer Security) is designed to provide security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. It is suitable for securing JSON encoded telemetry data sent to an external collector1.

 To reduce disruptions during a major software upgrade on a Cisco Nexus Series switch, technologies like VDC (Virtual Device Contexts) and vPC (Virtual Port Channels) can be implemented. VDC allows for the partitioning of a single physical device into multiple logical devices, which can be managed and operated independently. This means that one VDC can be upgraded while others remain operational, minimizing downtime. vPC enables the linking of two switches to create a single logical switch, providing redundancy and allowing for one switch to be upgraded while the other maintains the network operations1.

 An EPLD upgrade on a Cisco MDS 9000 Series Switch affects only the module that is being upgraded. It does not disrupt the active supervisor traffic, management connectivity to the switch, or cause the standby supervisor module to reload multiple times. The upgrade is designed to be as non-disruptive as possible1.

POAP is an automatic provisioning and zero-touch deployment feature that assists device owners in the

initial deployment and configuration of Nexus switches.

The feature works by checking for a local configuration script. If the script has been deleted, the switch has

been reset to factory settings, or this is the first boot-up, the POAP daemon will connect to a preset list of

servers to download an initial configuration file.

To perform this operation, the switch must first obtain an IP address from a local DHCP server. POAP

configuration settings can also be passed through the DHCP response.

Which conditions should be verified, so they need to be TRUE. Like no startup (A) and bootup (B). C means

that it needs to miss a license file and E means it needs to miss an NX-OS image.

The Bash script is designed to loop through the available namespaces and output all registered interfaces within the Cisco NX-OS Guest Shell. The correct code snippet to complete the script is option C, ifconfig "$ns". This command will display the network configuration for each namespace, allowing the engineer to view all registered interfaces.

References: The use of ifconfig in conjunction with namespace variables is a common practice in network scripting to retrieve interface information. For more detailed information on scripting in Cisco NX-OS, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide.

 An EPLD (Electronic Programmable Logic Device) upgrade on a Cisco Nexus 9000 Series Switch is used to upgrade the field-programmable gate arrays (FPGAs). FPGAs are integrated circuits that can be configured by a customer or a designer after manufacturing – hence “field-programmable”. They are used in Cisco switches to provide hardware functionalities in all modules, and EPLD image upgrades enhance hardware functionality or resolve known issues1.

Option C meets the security requirements for the Cisco UCS C-Series Server. It disables unencrypted communication by enabling HTTPS, sets the session timeout to 900 seconds (15 minutes), redirects HTTP to HTTPS to divert unencrypted traffic, and changes the SSH port to a nondefault value (2022), which is essential for CLI-based management.

References := For further details on securing Cisco UCS C-Series Servers, refer to the Cisco UCS C-Series Servers Integrated Management Controller CLI Configuration Guide, which provides instructions on configuring service profiles, security settings, and management access.

The configuration snippet in the exhibit shows that VSAN 100 is allowed on interface Ethernet1/12 with the command “switchport trunk allowed vsan 100”. This means option B, “Allow VSAN 100 on interface eth1/12”, is the correct answer. In Cisco Data Center Core Technologies, it’s essential to allow specific VSANs on an interface to enable traffic flow for those VSANs.References: Implementing and Operating Cisco Data Center Core Technologies (DCCOR) - Configuring FCoE

The output indicates that port channel 1 is trunking, which means it is configured to be an Inter-Switch Link (ISL). ISLs are used in Fibre Channel networks to connect switches and maintain the fabric topology. The “port mode is F” in the output also confirms that it’s an ISL, as F-ports are used for Fabric (switch) ports connecting to N-ports on another switch or node.

 In a VXLAN data center fabric, inter-VNI communication requires mapping Layer 2 (L2) VLANs to their respective L2 VNIs and associating them with the correct Layer 3 (L3) VNI that corresponds to the VRF. In this case, VLAN 100 is mapped to L2 VNI 2020, and for inter-VNI routing to occur, it must be associated with an L3 VNI that corresponds to the VRF, which is Test_Telco_VRF to L3 VNI 1010. References: For more detailed information, you can refer to the Cisco Programmable Fabric with VXLAN BGP EVPN Configuration Guide1 and the Data Center VXLAN EVPN guide

 To allow Layer 2 connectivity between Host 1 in VLAN 100 located in DataCenter 1 and Host 2 in VLAN 200 located in DataCenter 2, the correct OTV VLAN mapping configuration is option C. This configuration involves mapping VLAN 100 to VLAN 200 across the OTV overlay so that hosts in these separate VLANs can communicate as if they were in the same Layer 2 domain. The VLAN mapping is achieved by configuring the OTV edge devices in both data centers to associate the VLANs with each other.

The hybrid cloud model is the most suitable for the described scenario. It allows for a combination of local (private) cloud infrastructure with remote (public) cloud services. This model supports hosting the primary workloads in a local data center, utilizing remote data centers for backups, and provides the flexibility to scale out to a public cloud provider when necessary. The hybrid cloud model offers the benefits of both private and public clouds, including security, scalability, and flexibility, which aligns with the organization’s requirements.

 The commands shown in the exhibit configure Unicast Reverse Path Forwarding (uRPF) in loose mode on the interface Ethernet 2/2. The ip verify unicast source reachable-via rx command enables uRPF to check that the source address of a received packet has a route in the routing table and that the packet has been received from a valid interface that aligns with the routing table. This helps prevent IP spoofing by ensuring that packets are received from the expected interface.

References := This explanation is based on the principles of uRPF as described in Cisco’s security configuration guides and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials. For more detailed information, please refer to these resources.

 Policies that identify the connectivity between Endpoint Groups (EPGs) and the external connection when extending a bridge domain out of a Cisco ACI fabric are associated with L2Out and L3Out components. L2Outs are used to extend Layer 2 connectivity outside the ACI fabric, while L3Outs are used for Layer 3 external connections. These policies define how the ACI fabric will communicate with external networks

To prevent users from modifying root policies, the system administrator can define a custom user role and assign it to users. A custom user role can have specific privileges and scope of access that are different from the predefined user roles. For example, a custom user role can have read-only access to the root policies, but full access to the organization policies. By assigning this custom user role to users, the system administrator can ensure that only authorized users can modify the root policies, while still allowing users to manage their own organization policies. This way, the system administrator can avoid accidental changes to the boot policy or other root policies that can impact all service profiles and their storage connectivity. References :=

 To automate the provisioning of Cisco ACI objects using Terraform while ensuring that APIC counts the authentication login requests against the threshold to avoid a DOS attack, signature-based authentication should be used. This method involves obtaining an authentication token from Cisco APIC, which will use the token to authenticate. However, APIC counts these authentication requests and applies a threshold to prevent DOS attacks. After too many attempts, the user ID and password authentication method may fail as the threshold is exceeded. To circumvent this issue, signature-based authentication is recommended, where a signature is calculated using a private key and passed with the request. This signature is then used to authenticate the user without being counted against the threshold, thus avoiding the risk of exceeding it and failing authentication.

 To meet the high-security standards, the engineer should configure port security and fabric binding on VSAN 50. Port security prevents unauthorized devices from logging into the fabric by automatically learning and securing the World Wide Port Names (WWPNs) of devices connected to the switch ports. Fabric binding allows only authorized switches to join the fabric by creating a list of switch WWNs that are permitted to join a specific VSAN.

To monitor all LAN traffic on Fabric A from a blade server, the source should be configured as all uplink Ethernet ports in the test-span monitor session. This configuration allows the engineer to capture all LAN traffic that traverses the uplink Ethernet ports, providing a comprehensive view of the network activity related to Fabric A. By monitoring these ports, the engineer can analyze traffic patterns, detect anomalies, and ensure the proper functioning of the network.

 Since the AAA server is unreachable and TCP communication with the AAA servers is disabled, the network administrator must log in locally using a network-admin role. The upgrade files can then be downloaded from a remote TFTP server, which does not require TCP communication and can operate over UDP, thus bypassing the TCP restriction.

The benefit of adding Cisco HyperFlex Hardware Acceleration Cards to a HyperFlex deployment is increased compression efficiency. These cards are PCIe devices that offload the compression and decompression operations from the CPU, resulting in higher performance and lower latency for most storage workloads. The cards also reduce the CPU utilization and power consumption of the HyperFlex nodes, enabling more resources for other applications. The other options (offline encryption acceleration, increased network throughput, and GPU acceleration) are not benefits of the HyperFlex Hardware Acceleration Cards. References: For more information on the HyperFlex Hardware Acceleration Cards, please refer to the following resources:

Option A, which utilizes the SFTP protocol with a weekly schedule, aligns with the requirements. SFTP ensures encrypted transmission of data, addressing the need for secure backup. A weekly backup schedule is within the 48-hour Recovery Point Objective (RPO), as it guarantees that the most data that could be lost in a disaster is one week’s worth, which is acceptable within the given RPO. The Recovery Time Objective (RTO) of 4 hours is related to the restoration process rather than the backup schedule or protocol, so it is not directly influenced by the choice of Option A.

References := For more detailed information, refer to the Cisco UCS Manager Backup and Restore Guide, which provides guidelines on setting up disaster recovery policies, including backup schedules and transmission security.

When configuring the connection between a Cisco MDS 9700 Series Multilayer Director and a Cisco Nexus 5672UP switch, it’s important to consider the following:

• Ensure compatibility: Verify that both devices are running compatible NX-OS versions to ensure they can communicate properly.
• Configure interfaces: Set up the interfaces on both devices with the appropriate type (E, F, or TE), speed, and other relevant settings.
• Establish connectivity: Use the show interface command to confirm that the interfaces are up and the show flogi database command to verify that the Fibre Channel login has been successful.
• Zoning configuration: Configure zoning on the MDS 9700 to control access between devices connected to the fabric.
• VSAN setup: Ensure that the Virtual Storage Area Network (VSAN) is correctly configured and that both switches are part of the same VSAN if required for the topology.

 Microsegmentation is a feature of ACI that allows granular control of traffic between endpoints based on vCenter VM attributes, such as name, guest OS, or network adapter type. Microsegmentation works by creating a micro-EPG for each VM and applying contracts and policies to the micro-EPGs. When microsegmentation is enabled, ACI performs distributed switching and routing on the ESXi hosts using the Cisco Application Virtual Switch (AVS) or the Cisco Application Virtual Edge (AVE). This allows ACI to enforce policies at the hypervisor level, without requiring any changes to the physical network or the VM configuration. References :=

• Implementing and Operating Cisco Data Center Core Technologies (DCCOR) v1.2, Module 6: Cisco ACI, Lesson 6.3: Cisco ACI Integration
• Cisco ACI Virtualization Guide, Release 4.2(x), Chapter: Configuring Microsegmentation

 To block traffic between a subset of endpoints in an EPG based on specific VM attributes and the rest of the VMs in that EPG, the correct set of actions would involve setting “Allow Microsegmentation” under the EPG VMM Domain Association to “True” and setting “Intra-EPG Isolation” to “Enforced” for both the EPG and the uSeg EPG. This configuration ensures that microsegmentation is allowed and that intra-EPG isolation is enforced, effectively blocking the specified traffic.

In a vPC configuration, both Nexus switches (N7K-1 and N7K-2) are designed to work together to present themselves as a single logical entity to downstream devices. This design allows for a loop-free topology without the need for Spanning Tree Protocol (STP) to block any of the ports to prevent loops. As a result, both N7K-1 and N7K-2 share the same STP priority, making them appear as a single STP root to the rest of the network. This approach enhances the use of available bandwidth and provides redundancy without relying on STP to resolve loops.

References := The principles of vPC and its interaction with STP are well documented in Cisco’s technical literature, including the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials1. For a more detailed explanation, please refer to these resources.

An ISSU upgrade on the Cisco MDS 9000 Series Switch allows for software updates with minimal impact on the switch’s operation. The control plane remains up during the upgrade, ensuring continuous network operations and service availability. The process is carefully designed to prevent any significant downtime, and any brief disruption is kept well under the 120-second mark1.

A strict CoPP (Control Plane Policing) policy is designed to manage the traffic flow of control plane packets to protect the control plane of routers and switches from being overwhelmed by unnecessary or malicious traffic. When a ping sweep, which involves sending ICMP echo requests to multiple hosts to identify live devices on a network, is performed on a network connected through a switch with a strict CoPP policy, excess ICMP packets can be dropped to prevent them from consuming excessive resources. References: Cisco Data Center Core Technologies source documents or study guide

 The solution that meets the requirements for implementing an automation solution to allow the backup of the configuration of Cisco Nexus series switches to a centralized location is the Guest Shell. The Guest Shell is a Linux-based container that runs on the Cisco Nexus operating system and provides a secure environment for running Python scripts and custom applications. The Guest Shell supports the RPM packaging format, which allows the team-developed custom monitoring scripts to be easily installed and managed. The Guest Shell is isolated from the underlying Cisco Nexus operating system, which means that it has no impact on the operating system if the resource contention occurs. The Guest Shell also allows the use of Python to expand the existing automation framework, such as using the NX-API or the Cisco Nexus Python SDK to interact with the switch configuration and state. References :=

When converting a Cisco MDS switch to support NPIV mode, it must be enabled globally on all VSANs (B). NPIV allows multiple virtual machines to share a single physical Fibre Channel port, which means that enabling it on all VSANs ensures that this functionality is available across the entire network.

 Option D and C are the correct policies that must be configured to meet the requirements. A Maintenance Policy specifies how the changes are applied when a service profile is associated or disassociated with a server or when an updated service profile is applied to a server. A Power Control Policy allows users to select how Cisco UCS Manager should restore power to the servers in a chassis after the chassis loses power. References:

Option C is the correct configuration that is expected to be saved by using a logical configuration backup. A logical configuration backup includes the service profiles, service profile templates, policies, pools, and logical LAN and SAN connectivity configuration. It does not include the systems, roles, or servers configuration, which are part of the full state or all configuration backups. References:

Puppet, an open-source configuration management tool, requires the Open Agent Container (OAC) to run on Cisco NX-OS. The OAC provides a contained environment where third-party agents like Puppet can run without affecting the host NX-OS system.

References: The requirement for OAC when using Puppet in a Cisco NX-OS environment is outlined in the Cisco NX-OS Puppet Configuration Guide, which explains the integration of Puppet with Cisco NX-OS and the necessary components.

 In a Cisco NX-OS environment, Ansible requires the NX-API to be enabled for HTTP/HTTPS protocol communication. NX-API is a REST-like API for NX-OS, providing a method for external applications to access the switch over HTTP/HTTPS, allowing for both CLI and simple object-based programming. This is necessary for Ansible to manage the device and execute automation tasks over these protocols.

References: Cisco’s official documentation on NX-API and Ansible’s documentation for Cisco NX-OS support.

 Configuring an IP helper address on interface VLAN 10 of the management switch is the correct action to meet the requirements. This configuration allows the management switch to forward DHCP requests from the new switches in different VLANs to the DCNM server, which can then use the zero-touch POAP feature to facilitate fabric creation.

APM supports ERSPAN. This will be ERSPAN destination. We need source session from switch. https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/16-3/configuration_guide/b_163_consolidated_3850_cg/b_163_consolidated_3850_cg_chapter_01001010.pdf

Two statements that are true about the process of performing an EPLD upgrade on a Cisco MDS 9000 series Switch are:

• If an upgrade is interrupted, the upgrade continues after a connection is restored. This means that the EPLD upgrade process is resilient to network or power failures and can resume from where it left off once the connection is reestablished.
• The upgrade can be performed from the standby supervisor module. This allows the active supervisor module to continue to provide management and control functions while the EPLD upgrade is in progress. The standby supervisor module can also take over the active role if needed during the upgrade.

The other statements are not true because:

• The active supervisor cannot be upgraded. The EPLD upgrade process requires the supervisor module to be in standby mode before it can be upgraded. The active supervisor module must be switched to standby mode manually or automatically before the upgrade can begin.
• Modules do not need to be online to be upgraded. The EPLD upgrade process can upgrade modules that are offline or powered down as well as modules that are online. The offline modules are upgraded when they are brought online or powered up.
• The upgrade process disrupts all modules that are being upgraded. The EPLD upgrade process requires a module reload for each module that is being upgraded, which causes a temporary disruption of traffic and services on that module. The disruption can be minimized by using hitless or non-disruptive EPLD upgrade modes, which preserve the forwarding state and configuration of the module during the reload. References: For more details on how to perform an EPLD upgrade on a Cisco MDS 9000 series Switch, please refer to the following resources:

 Option C is the correct answer. Puppet is an open-source software configuration management tool that is used for deploying, configuring, and managing servers. It allows for the centralized management of various system configurations and aligns UCS servers to their desired state by periodically acquiring configurations from a centralized server. References:

• Cisco Data Center Core Technologies, Module 5: Data Center Automation and Orchestration, Lesson 5.1: Describe Automation and Orchestration Concepts, Topic 5.1.1: Configuration Management Tools

 To meet the requirements of automating the provisioning of Cisco Nexus 9000 Series Switches while hiding Admin and Config Menu items in Interface Manager, the roles of network-operator and access-admin should be assigned. The network-operator role permits device operations within Interface Manager, and the access-admin role is likely to have the necessary permissions to manage user access without exposing sensitive admin and configuration options.

References: = For more information on user roles and permissions in Cisco Data Center Network Manager (DCNM), you can refer to the official Cisco documentation and guides related to DCNM user role configuration.

To prevent unauthorized changes at the root level and to restrict access up to the organization level, the appropriate action is to assign users to a specific Cisco UCS locale. A locale is a logical grouping that defines the scope of user permissions in Cisco UCS Manager. By assigning users to a locale, their access can be limited to specific organizations or service profiles, preventing them from modifying policies at the root level.

 The command rpm -Uhv is used to upgrade or install an RPM package on Linux-based systems. In the context of upgrading bash on a Cisco Nexus 9000 Series Switch, this command would be used to install the new bash package from the provided file path.

 Option C is the correct configuration to apply a power redundancy policy on a Cisco UCS C-Series Rack Server that supports two power sources. The power redundancy policy determines how the server uses the available power supplies to optimize power usage. The grid option means that the server uses power from both power supplies simultaneously. If one power supply fails, the server continues to operate with the remaining power supply. The other options are not suitable for this requirement. The n+1 option means that the server uses one fewer power supply than the number of power supplies that are installed. If a power supply fails, the server uses the extra power supply. The non-redundant option means that the server uses only one power supply, regardless of the number of power supplies that are installed. If the power supply fails, the server shuts down. The ps-redundant option means that the server uses power from the most efficient power supply. If the power supply fails, the server switches to another power supply. References:

The In-Service Software Upgrade (ISSU) process is designed to upgrade the system software with minimal disruption to the network. Nonstop forwarding (NSF) and stateful switchover (SSO) are two features that work together to maintain packet forwarding and switch state information during the ISSU process. NSF allows the router to continue forwarding packets even when the route processor is failing over, while SSO synchronizes state information between redundant route processors to ensure a seamless transition during a failover1.

References := For a deeper understanding of the ISSU process and its associated features, you can refer to Cisco’s official documentation on In-Service Software Upgrade (ISSU), which provides detailed information on how NSF and SSO contribute to a nondisruptive upgrade

The configuration set in Option C is designed to invoke a Python script when the router becomes unreachable. It uses an event scheduler to track the state of the router and, if it is not up, it triggers the Python script “routerdown.py” at specified intervals. This setup ensures that the operations team is alerted promptly when the router DC-RTR-1 becomes unreachable, allowing for quick response and troubleshooting.

To schedule the firmware upgrade of the Red1 and Red2 leaf switches with the requirements of minimal upgrade time, no service impact, and parallel upgrade, SchedulerPolicy1 and SchedulerPolicy2 with a one-time window trigger that has maximum concurrent nodes 2 should be used. This allows both Red1 and Red2 to upgrade simultaneously within the same maintenance window, thus minimizing the time and avoiding any service disruption.

 A community cloud Infrastructure as a Service (IaaS) deployment model is suitable for several companies that need to operate the same application environment and integrate it with third-party protocols. It allows the development team to have control over the infrastructure, including the operating system, Python interpreter, and libraries

To implement FCoE on a Cisco Nexus 9000 Series Switch-based infrastructure that includes dual-homed fabric extenders and supports jumbo frames with port channels, the engineer must configure the system to handle large frame sizes and ensure FCoE functionality is enabled on the fabric extenders. The actions in Option A include configuring the interface with an MTU of 9516 to support jumbo frames and disabling NPIV, which is not required for FCoE operation on fabric extenders. Option D involves executing the command ‘fcoe enable-fex’ to enable FCoE on the fabric extenders and setting the MTU to 9216 on FEX uplinks to support jumbo frames1

 To directly connect a Fibre Channel storage array to a Cisco UCS domain, configuring a new VSAN is essential as it creates a separate fabric to isolate the storage traffic. Additionally, creating a Storage Connection Policy is necessary to define how the UCS domain will communicate with the storage array, including zoning and VSAN membership.

When configuring a vHBA template in Cisco UCS Manager, the engineer needs to specify the logical addresses used by the vHBA and the path through which the SAN traffic flows. The two resources that must be specified in the vHBA template are the WWN (World Wide Name) and the Fabric ID. The WWN is a unique identifier for the vHBA that is used for zoning and LUN masking in the SAN environment. The WWN can be assigned manually or automatically from a WWN pool. The Fabric ID is a parameter that determines which fabric interconnect (A or B) the vHBA is associated with. The Fabric ID can be set to a specific value or to ‘default’, which allows the system to choose the best available fabric interconnect based on the availability and load balancing policies. References :=

 The correct configuration for a unified I/O link that supports both LAN and SAN traffic using a single Ethernet transport is to configure the interface as a trunk port. This allows multiple VLANs (for LAN traffic) and VSANs (for SAN traffic) to coexist on the same physical link. The auto qos trust dscp command ensures that the Quality of Service (QoS) markings are preserved, which is essential for maintaining traffic prioritization across the network.

When there is a domain name change, and the Cisco UCS Manager needs to be available over HTTPS, generating a new default key ring certificate from the Cisco UCS Manager (B) is typically the recommended action. This ensures that the HTTPS service has a valid certificate that matches the new domain name.

 To achieve the objective of bringing down all VLANs on an interface that are not enabled for FCoE while allowing those that are enabled for FCoE to continue carrying SAN traffic, the shutdown force command should be applied to the Ethernet interface. This command ensures that only the non-FCoE VLANs are shut down, and it does not affect the operation of the VLANs carrying FCoE traffic. The shutdown force command is used specifically to override any configurations that might prevent the interface from being shut down, such as EtherChannel or Spanning Tree Protocol (STP) settings.

References: The solution aligns with Cisco’s best practices for managing VLANs in a Cisco ACI environment, particularly when dealing with FCoE traffic. For more detailed information, refer to the Cisco documentation on FCoE configurations and VLAN management in the context of Cisco ACI fabrics, which can be found in the Cisco Data Center Core Technologies (DCCOR) study materials and on the Cisco official website under the Data Center and Virtualization section1

 Option D is the correct choice. Configuring the vPC role priority and enabling the peer-gateway feature are recommended practices for enhancing vPC convergence times. The peer-gateway feature allows for local forwarding of packets without the need to cross the vPC peer link, which can significantly reduce convergence times during primary peer device failures and recoveries. This approach ensures that the vPC system can quickly adapt to changes and maintain traffic flow even in the event of a device failure123.

A logical configuration backup of a Cisco UCS Manager database is a file that contains all of the configurations that are stored in the Cisco UCS Manager database, such as policies, pools, service profiles, templates, and firmware versions. The file has an extension .tgz and can be created and restored using the Cisco UCS Manager GUI or CLI. A logical configuration backup also contains the configuration organizations and locales, which are logical entities that group and isolate resources within a Cisco UCS domain. Organizations and locales can be used to delegate administrative tasks and privileges to different users or groups. The other options (AAA and RBAC configurations, VLAN and VSAN configurations) are not part of a logical configuration backup, but rather a full state backup, which is a different type of backup that includes the operational state and statistics of the Cisco UCS domain. References: For more information on how to create and restore a logical configuration backup of a Cisco UCS Manager database, please refer to the following resources:

 The command set in Option C is likely to configure the Cisco MDS switches to use FC-SP for authentication and to ensure communication remains encrypted even when the AAA server is not reachable. This would typically involve configuring the switches to fall back on local authentication databases and enabling features such as DHCHAP (Diffie-Hellman Challenge Handshake Authentication Protocol) to maintain encrypted communication12.

References := For a detailed configuration guide, you can refer to the Cisco MDS 9000 Series Security Configuration Guide, Release 8.x and 9.x, which provides instructions on configuring security features on external AAA servers and FC-SP and DHCHAP

Option B is the correct answer because it meets both requirements stated in the question. The configuration permits SSH connectivity from a jump host with an IP address of 10.10.10.10/24 and allows all switches to connect via SSH to other devices from the subnet of 10.20.20.0/24.

In this option, the access list acl-1 is configured to permit TCP traffic from host 10.10.10.10/32 (the jump host) on any port, and access list acl-2 is configured to permit TCP traffic from subnet 10.20.20.0/24 on any port.

The ‘line vty’ configuration applies these access lists for inbound (in) and outbound (out) SSH sessions respectively, ensuring that only the specified source IP addresses are allowed for remote SSH management connectivity1.

The virtual MAC address that is the default for HSRP version 2 group 10 is 0000.0C9F.F00A. HSRP (Hot Standby Router Protocol) is a protocol that provides redundancy and load balancing for IP networks by allowing multiple routers to share a virtual IP address and MAC address. HSRP version 2 supports up to 4096 groups, and uses a different MAC address format than HSRP version 1. The MAC address format for HSRP version 2 is 0000.0C9F.FXXX, where XXX is the hexadecimal value of the group number. For group 10, the hexadecimal value is 0A, so the MAC address is 0000.0C9F.F00A. References :=

The configuration shown in the exhibit indicates that FCIP (Fibre Channel over IP) is configured with ip-compression mode2 enabled on a Cisco MDS 9000 Series switch. This means compression is performed by using software (Option D), as mode2 refers to software-based compression in FCIP configurations. The other options are not correct based on the configuration. The switch does not attempt to make two TCP connections, as there is no tcp-connections command in the configuration. Compression is not performed by using hardware, as mode1 refers to hardware-based compression in FCIP configurations. Mode2 is not enabled by default, as the default mode for FCIP compression is none. References:

 The requirements specify the need for two-factor authentication and encrypted AAA packets using TCP port 49, which is the default port for TACACS+. TACACS+ provides additional security features suitable for two-factor authentication, unlike LDAP. Therefore, removing the LDAP provider and creating a TACACS+ provider in user management would fulfill these requirements.

A Multi-Site Orchestrator deployment requires two orchestrators to be deployed, one in each of the two main data center sites. The Multi-Site Orchestrator is a software component that enables the management and orchestration of multiple Cisco Application Centric Infrastructure (ACI) fabrics that are geographically distributed across different locations. The Multi-Site Orchestrator provides a single pane of glass for configuring, monitoring, and troubleshooting the ACI fabrics, as well as synchronizing policies and tenants across the sites. The Multi-Site Orchestrator also supports disaster recovery and high availability scenarios by allowing the replication of data and services between the sites. The Multi-Site Orchestrator deployment consists of two orchestrators that form a cluster and communicate with each other using a secure channel. Each orchestrator is connected to one or more ACI fabrics in the same site, and acts as a proxy for the other orchestrator to access the ACI fabrics in the remote site. The orchestrators use a leader-election algorithm to determine which one is the active orchestrator and which one is the standby orchestrator. The active orchestrator handles all the requests from the users and the applications, while the standby orchestrator monitors the health and status of the active orchestrator and takes over in case of a failure. The orchestrators also perform periodic data synchronization to ensure consistency and reliability. References :=

 When storm control is applied to an interface with a zero percent value, it means that the switch will not tolerate any traffic that exceeds the bandwidth of the interfaces during a streaming window. The switch monitors the levels of incoming broadcast, multicast, and unicast traffic over a 1-second interval. When the configured threshold level is reached, further traffic in this category is dropped until the level falls below the threshold.

 Option D is the correct configuration to enable the Cisco UCS Manager to manage a Cisco UCS C-Series server by using a single cable for management and data traffic. The commands enter the server scope, then the cimc scope, then the mgmt-conn scope with the sideband option, which enables the management connection through the sideband interface. Then, the mgmt-conn-state is set to enabled and the changes are committed to the buffer. References:

The FCoE Initialization Protocol (FIP) uses a 24-bit FC-MAP and concatenates a 24-bit Fibre Channel ID to create a fabric-provided MAC address. This is part of the FIP’s role in establishing and maintaining the virtual links between an E-Node and the Fibre Channel Forwarder (FCF). The MAC address is essential for the E-Node to participate in FCoE communications within the fabric. The process ensures that each E-Node has a unique address on the Ethernet network, which encapsulates the Fibre Channel frames for transport. References := Cisco MDS 9000 Series FCoE Configuration Guide, Release 9.x

 NX-API is a feature that enables the use of JSON and XML encoding when a Cisco Nexus 7000 series switch is deployed.

NFSv4 offers several advantages over Fibre Channel protocol, one of which is improved security. NFSv4 is designed to be more secure than its predecessors, providing strong security features that are not inherent in Fibre Channel. It includes mechanisms for authentication, integrity, and privacy, which are part of its standard protocol suite. NFSv4 also integrates well with security infrastructures like Kerberos, allowing for secure, authenticated access to file systems over a network.

To migrate a Cisco UCS C-Series server from Cisco SingleConnect to direct integration mode with immediate discovery and auto-acknowledge policies, the steps in Option C are appropriate. These steps typically involve disconnecting the cables from the FEX, connecting them to the appliance ports on the fabric interconnect, and reacknowledging the server

To create a virtual Fiber Channel interface and associate it with an Ethernet physical interface, the correct configuration commands would be:

• Enter the interface configuration mode for the virtual Fiber Channel interface using the command interface vfc7.
• Bind the virtual Fiber Channel to the Ethernet interface using the command bind interface ethernet 1/7.

This configuration associates the virtual Fiber Channel interface with VSAN 7 and maps VLAN 700 to the VSAN, as required by the converged network adapter (CNA).

References := The explanation is based on standard practices for configuring virtual Fiber Channel interfaces in a Cisco environment, as detailed in Cisco’s data center configuration guides and technical documentation.

 Python is a versatile scripting language that supports the rapid creation and removal of logical containers, the development of custom modules and data structures, and is extensible with a wide range of external libraries and modules. It also allows for on-demand execution, making it ideal for automating tasks in Cisco ACI Fabric

 The correct answer is option C. The fabric binding configuration in option C matches the output required for the Cisco MDS 9000 Series Switch. Fabric binding enhances the security of the SAN fabric by allowing only authorized switches to join the fabric. The configuration includes specifying the switch world wide name (swwn), domain ID, and member world wide node name (nwwn) to ensure that only the specified devices can participate in the fabric.

References: For more information on fabric binding and its configuration, you can refer to the Cisco MDS 9000 Series Fabric Switches Configuration Guide and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials.

To establish a VSAN trunk between Switch 1 and Switch 2, you would typically configure E Port with Trunk Mode On. This is because Switch 1 is already configured with an E port in Trunk Mode Auto, and for trunking to be established, the other switch should also be set to trunk mode but with a static configuration (On) to ensure compatibility and trunk formation.

 Completing the vPC domain implementation requires adding the vPC member ports to the vPC channel group. This action ensures that all member ports are correctly bundled into the vPC, allowing for consistent forwarding behavior and redundancy across the vPC peer switches2.

To meet the specified requirements, a custom role needs to be created for User1 that grants full access to both the Fabric Interconnect infrastructure and network security operations, as well as storage operations configuration. This custom role ensures that User1 has the necessary permissions across different areas of the UCS Manager. Using LDAP for role-mapping with Active Directory allows for the integration of UCS Manager with the existing AD infrastructure, enabling centralized management of user credentials and access rights12.

References := The process for integrating Cisco UCS Manager with Active Directory and configuring custom roles can be found in the official Cisco documentation, such as the Cisco Secure Access Control System Configuration Guides and the Cisco Community discussions on UCS Manager and Active Directory integration12. These resources provide step-by-step instructions and best practices for setting up access control in UCS Manager using Active Directory.

Enabling the vPC peer gateway feature on the vPC devices allows them to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer. This capability allows both vPC peers to forward traffic and eliminates traffic disruption when one of them goes down, ensuring high availability in network operations.

References: = For more detailed information, you can refer to the Cisco Nexus 9000 Series NX-OS High Availability and Redundancy Guide, which provides guidelines on configuring vPC peer gateway features for enhanced network stability and availability.

To prevent data corruption due to cross fabric communication in an FCoE environment, the network engineer must apply the configuration Switch(config)#fcoe fcmap 0e,fc,2a to the Cisco Nexus Unified Switches. This configuration sets the FCoE MAC address prefix (fcmap) to a custom value of 0e,fc,2a, which is different from the default value of 0e,fc,00. The fcmap is used to identify the FCoE traffic and map it to the corresponding Fibre Channel ID (FCID). By using a custom fcmap, the network engineer can avoid the possibility of FCID conflicts or overlaps between different FCoE fabrics, which can cause data corruption or loss. The custom fcmap must be configured on all the switches in the same FCoE fabric, and must be unique across different FCoE fabrics. References :=

• Create a user defined role and add the required privileges.
• Assign a role to a user. Comprehensive and Detailed Explanation: = To meet the requirements of adding a new FCoE VLAN to the core switches with restricted read-write access, the network engineer must create a user defined role and assign it to a user. A user defined role is a custom role that can be created to grant specific privileges and permissions to a user, based on the tasks and functions they need to perform. A user defined role can be created using the role command, and then the required privileges can be added using the rule command. For example, to create a role named FCoE-admin and add the privilege to configure FCoE VLANs, the following commands can be used:

role FCoE-admin rule 1 permit read-write feature fcoe rule 2 permit read-write feature vlan

After creating the user defined role, it can be assigned to a user using the username command. For example, to assign the FCoE-admin role to a user named John, the following command can be used:

username John role FCoE-admin

By creating and assigning a user defined role, the network engineer can ensure that the user has the minimum required privileges to perform the FCoE VLAN configuration, without granting them full network-admin access or modifying the existing roles. References :=

 A logical backup includes all logical configuration settings such as service profiles, VLANs, VSANs, pools, and policies1. Since the end users are only allowed to make changes to the Service Profile configuration, a logical backup is appropriate as it will capture the state of these configurations without including system settings. Scheduling the logical backup at the start of the weekend ensures that the latest configurations are saved before any changes occur. Scheduling the import of this backup on Monday morning will restore the configurations to their state at the time of the backup, thus reverting any changes made by the end users during the weekend1.

References := The Cisco UCS Manager documentation provides detailed instructions on how to schedule backups and imports, which can be found in the official Cisco resources1. These documents outline the steps for setting up scheduled backups and imports, ensuring that the UCS Manager configuration can be restored to a specific state as required.

 Embedded Event Manager (EEM) is a powerful tool used in Cisco devices, including MDS switches, to automate tasks and create custom scripts that react to network events. For an administrator needing to configure an automated policy to shut down a link when a threshold is exceeded, EEM is the appropriate feature to use. It allows the creation of event-driven automation scripts that can be triggered when certain conditions are met, such as a link exceeding a specified threshold.

Option C and E are the correct requirements when planning a Cisco HyperFlex All Flash standard cluster installation using three HX240c M5 servers. Option C states that if the Jumbo MTU option in the HyperFlex installer is enabled, then jumbo frames must also be enabled on the upstream switches, which is true for optimal performance and compatibility. Option E states that the servers must be discovered, unassociated, and connected to each fabric interconnect, which is also true for the cluster installation process. The other options are either false or not applicable for the scenario. References:

The command show incompatibility-all system bootflash:n7000-s1-dk9.4.2.4.bin is used to display the compatibility of the software in the system bootflash file on a Cisco Nexus 7000 Series Switch. This command is crucial for administrators to verify if the current configuration is compatible with the new software version before performing a downgrade or upgrade, ensuring that there are no conflicts or issues that could potentially disrupt network operations1.

When implementing NPV mode on a Cisco MDS 9000 Series Switch, it is crucial to ensure that NPIV is enabled on the upstream switch. NPV mode allows the switch to pass traffic between end devices and the core without consuming a domain ID. For NPV to function correctly, the upstream switch must support NPIV, which allows multiple virtual machines to share a single physical port without conflicts. References := Switch Configuration - Configuring N Port Virtualization

Option A is the correct order of reloading components during the process of upgrading the EPLDs of the fabric modules for a Cisco MDS director-class switch. The EPLD upgrade is performed on one fabric module at a time, and the fabric module is reloaded after the upgrade. The other fabric modules and the switching platform are not reloaded during the process. References:

To achieve the most optimal on demand CPU performance while configuring the BIOS settings of a UCS C-series rack mount server, you should set the CPU Performance option to C0/C1 state. This option enables the CPU to operate in the highest performance state (C0) or the lowest power state (C1) depending on the workload demand. This allows the CPU to maximize its performance and efficiency without compromising its thermal and power limits. The other options (C6 Retention, C2 state, and C6 non-Retention) reduce the CPU performance by putting the CPU into deeper sleep states (C2 or C6) when idle, which can increase the latency and power consumption when resuming the CPU activity. References: For more details on how to configure the BIOS settings of a UCS C-series rack mount server, please refer to the following resources:

 The backup operation type that does not include the Preserve Identities feature is the logical configuration. This type of backup includes the settings and configurations that are logically defined within the Cisco UCS Manager, such as service profiles, policies, and management settings. However, it does not include the unique identifiers or ‘identities’ such as MAC addresses, WWN pools, and UUIDs, which are preserved in other types of backups like system configuration and full state.

References: The information about different backup operation types and the specifics of what each includes can be found in the Cisco Data Center Core Technologies documentation and the Cisco UCS Manager Backup and Restore Management Guide1.

 This type of backup includes information about VLANs, VSANs, and other policies and is in XML format, which is human-readable. Although the question specifies the use of UDP, none of the options provided use UDP as they are all TCP-based protocols; however, TFTP is often confused with being UDP-based because it is a lightweight protoco

The Peer Gateway feature on Cisco Nexus switches is designed to address the exact scenario described. When enabled, it allows the vPC peer switches to forward traffic based on the SVI MAC address, even if it is not the HSRP MAC address. This is particularly useful in cases where end devices do not use the HSRP virtual MAC address for the gateway and instead use the physical MAC address of one of the HSRP routers1. By using the Peer Gateway feature, both N9K_1 and N9K_2 will be able to forward traffic for VLAN 23, ensuring that the packets are not dropped due to the vPC loop prevention mechanism123.

References: = This information is supported by Cisco’s documentation on Nexus 5500 Platform Layer 3 and vPC Operations, which explains the use of the peer-gateway command to allow Layer 3 forwarding in scenarios where the destination MAC of the incoming packet is the MAC of its vPC peer switch1. Additionally, discussions in the Cisco Community confirm the necessity of this feature when certain devices on the network do not properly send traffic to the MAC address specified in the ARP234

Port security on Cisco MDS 9000 Series Switches is designed to prevent unauthorized devices from accessing the fabric. When port security is enabled, only the configured sWWN (switch World Wide Name) is authorized to participate in the fabric. This ensures that unauthorized switches or devices cannot log in or access the network, enhancing security within the data center. References: Implementing and Operating Cisco Data Center Core Technologies (DCCOR v1.2)

The Python code snippet provided imports the json module and loads a JSON file into a variable named var1. Since JSON files inherently represent object data as dictionaries in Python, the resulting data structure is a dictionary. This is evident from the output shown, which displays a dictionary with nested dictionaries and lists, containing keys like ‘bd’, ‘ap’, ‘name’, etc., and corresponding values.

References := The explanation is based on standard Python data structures and JSON file handling as described in Python documentation and typical Python programming resources. JSON objects are represented as dictionaries in Python, which is a fundamental concept in working with JSON data in the language.

Option A is the correct configuration to meet the requirements of configuring system logging on the MDS switch. The commands set the console logging level to 5, which corresponds to the severity level of “warning” and above, and set the exec-timeout to 300 seconds, which means that the users will be logged out of the console after 5 minutes of inactivity. The other options are either incorrect or incomplete for the task. References:

 ARP suppression is a feature used in VXLAN/EVPN environments to optimize ARP responses and reduce unnecessary ARP broadcasts across the fabric. When ARP suppression is enabled, the local VTEP (VXLAN Tunnel Endpoint) can respond to ARP requests for known IP-to-MAC address bindings, which are learned via the BGP EVPN control plane. This prevents the need for ARP broadcasts to be sent across the entire VXLAN fabric, thus optimizing the ARP response mechanism and reducing broadcast traffic1.

 Enabling the DHCP relay agent on a switch allows it to forward DHCP BOOTREQUEST packets from clients to a DHCP server, even if they are not on the same physical subnet. This is crucial for clients to obtain an IP address and other network configuration parameters from a DHCP server that is not locally present on the subnet.

References: Detailed information on DHCP relay agents can be found in the Cisco Data Center Core Technologies (DCCOR) study guide or source documents, particularly in the chapters discussing DHCP configuration and management in network environments.

 IP ARP suppression (D) is used in VXLAN EVPN environments to minimize flooding. When enabled, it allows the local switch to respond to ARP requests for known hosts, thus preventing the need to flood these requests across the entire network segment1. This feature is particularly useful in scenarios where there is a large amount of ARP traffic that could potentially lead to flooding, as it reduces unnecessary broadcast traffic by handling ARP resolution within the control plane2.

References: The role and configuration of IP ARP suppression in VXLAN EVPN environments are detailed in Cisco’s documentation and best practice guides for VXLAN BGP EVPN

 Increasing the vPC delay restore timer can help prevent packet loss during a vPC peer switch reload. This timer delays the restoration of vPCs after a peer link recovery, allowing enough time for all the systems to stabilize and for routing protocols to converge, thus avoiding potential packet loss1.

Option C is the correct command to make an XML backup of Cisco UCS Manager. The command creates a backup file named “all-config9.bak” that contains all system and service profiles configuration. The command also specifies the protocol as SCP (Secure Copy Protocol), which transfers the backup file using an authenticated and encrypted tunnel. References:
