GET VPN (Group Encrypted Transport VPN) is a tunnel-less VPN technology that uses a single security association (SA) for all routers in a group. This allows GET VPN to natively support MPLS and private IP networks, without requiring any additional encapsulation or tunneling protocols. GET VPN also supports multicast traffic without GRE, which reduces overhead and improves performance. FlexVPN is a newer VPN solution that covers all VPN types, such as site-to-site, hub and spoke, and remote access. FlexVPN uses IKEv2 for all VPN types, which offers some advantages over IKEv1, such as resiliency and fewer messages. However, FlexVPN requires newer hardware and software versions to support its features. FlexVPN also relies on GRE or static and dynamic point-to-point interfaces to support MPLS and private IP networks, which adds complexity and overhead. Therefore, a benefit of using GET VPN over FlexVPN within a VPN deployment is that GET VPN natively supports MPLS and private IP networks, without requiring any additional encapsulation or tunneling protocols. References:

The amount of URI text that is stored in Cisco WSA log files is controlled by the log-entry size parameter, which can be configured using the advancedproxyconfig command. The log-entry size parameter specifies the maximum number of bytes of the URI that will be logged for each request. The default value is 1024 bytes, but it can be changed to any value between 1 and 4096 bytes. If the URI is longer than the log-entry size, it will be truncated and a plus sign (+) will be appended to indicate that the URI was cut off. Configuring a small log-entry size can reduce the disk space and bandwidth consumption of the log files, but it can also limit the visibility and analysis of the requests.

Dual-SSID BYOD is the term for when an endpoint is associated to a provisioning WLAN that is shared with guest access, and the same guest portal is used as the BYOD portal. This flow is a unique capability of ISE where the user does not have to log in twice, as ISE can take the user information from the 802.1X session and direct the user to the BYOD flow. Once the endpoint is onboarded, it is reconnected to the secured WLAN for full network access. This flow is different from single-SSID BYOD, where the endpoint associates to a secure WLAN, gets onboarded, and then reconnects to the same WLAN12. References: 1: ISE BYOD: Dual vs. Single SSID Onboarding - Cisco Community 2: Cisco ISE BYOD Prescriptive Deployment Guide - Cisco Community

NetFlow is a Cisco IOS application that provides statistics on packets flowing through the router. NetFlow is based on 7 key fields that identify a flow, such as source and destination IP addresses, source and destination port numbers, layer 3 protocol type, ToS byte, and input logical interface. To enable NetFlow on a router, IP routing must be configured first, because NetFlow relies on IP addresses to classify and monitor traffic. SNMPv3, syslog, and VRF are not required for NetFlow configuration, although they can be used for other purposes such as network management, logging, and virtualization. References:

Cisco Identity Services Engine (ISE) is a product that provides comprehensive and scalable access policy enforcement for wired and wireless networks. ISE supports TACACS+ for device administration, which allows for granular control over the commands and actions that network administrators can perform on network devices. ISE also supports 802.1X, MAB, and WebAuth for network access, which enables authentication and authorization of users and endpoints based on various attributes, such as identity, device type, posture, location, and time. ISE can also integrate with other Cisco security products, such as Cisco Stealthwatch and Cisco AMP for Endpoints, to provide enhanced visibility and threat detection. Therefore, ISE is the product that meets all of the requirements stated in the question. References :=

Sandboxing is a feature that is leveraged by advanced antimalware capabilities to be an effective endpoint protection platform. Sandboxing allows an endpoint protection platform to isolate suspect files in a safe environment and analyze their behavior and impact without affecting the rest of the system. Sandboxing can help detect and prevent unknown or zero-day malware that may evade traditional signature-based detection methods. Sandboxing can also provide valuable threat intelligence and forensic data for further investigation and response.

Big data, storm centers, and blocklisting are not features that are leveraged by advanced antimalware capabilities to be an effective endpoint protection platform. Big data refers to the large volume, variety, and velocity of data that can be used for various purposes, such as analytics, machine learning, or business intelligence. Storm centers are centralized hubs that monitor and respond to cyber incidents and threats. Blocklisting is a method of preventing access to malicious or unwanted domains, IP addresses, or files by adding them to a list of blocked entities. References:

 Suppression is a feature of Cisco Next Generation Intrusion Prevention System (NGIPS) that allows you to reduce false positives and unwanted alerts by filtering out specific traffic from the intrusion detection and prevention process. You can configure suppression based on different criteria, such as port, rule, source, destination, and network. The two valid suppression types for this question are port and rule. Port suppression allows you to exclude traffic based on the source or destination port number, or both. For example, you can suppress alerts for port 80 (HTTP) traffic if you are not interested in web-based attacks. Rule suppression allows you to exclude traffic based on the rule ID (SID) or the rule category. For example, you can suppress alerts for rules that belong to the policy-violations category if you are not concerned about them. You can also suppress alerts for specific rules that are not relevant to your network or generate too many false positives. References

AAA stands for Authentication, Authorization, and Accounting. It is a framework that provides security to network resources by controlling who can access them (authentication), what they can do (authorization), and what actions they perform (accounting). AAA can be implemented by using the local database of the device or by using an external server such as Cisco ISE (Identity Services Engine).

The question asks which configuration item makes it possible to have the AAA session on the network. A session is a logical connection between a user and a network device. A session can be initiated by various methods, such as console, telnet, SSH, PPP, etc. Each session can have different AAA policies applied to it, depending on the method list configured for that session.

A method list is a set of rules that define the authentication, authorization, and accounting methods to be used for a particular session. A method list can be named or default. A named method list is applied to a specific session by using the login, authorization, or accounting keyword followed by the name of the method list. A default method list is applied to all sessions that do not have a named method list configured.

The configuration item that makes it possible to have the AAA session on the network is the aaa authorization network default group ise command. This command configures a default method list for network authorization, which is the process of determining the network services and attributes that a user is allowed to access after authentication. The command specifies that the network authorization method is group, which means that the device will use an external server (such as Cisco ISE) to obtain the authorization information for the user. The command also specifies that the name of the server group is ise, which means that the device will use the server group defined by the aaa group server radius ise command.

The other options are incorrect because they do not configure a default method list for network authorization. Option A configures a named method list for login authentication, which is the process of verifying the identity of the user. Option B configures a default method list for enable authentication, which is the process of verifying the identity of the user who wants to enter the privileged EXEC mode. Option D configures a default method list for exec authorization, which is the process of determining the commands and features that a user can access in the EXEC mode. References:

Explanation

Zero Trust is a security framework requiring all users, whether in or outside the organization’s network, to be authenticated, authorized, and continuously validated for security configuration and posture before being granted or keeping access to applications and data. Zero Trust assumes that there is no traditional network edge; networks can be local, in the cloud, or a combination or hybrid with resources anywhere as well as workers in any location.

The Zero Trust model uses microsegmentation — a security technique that involves dividing perimeters into small zones to maintain separate access to every part of the network — to contain attacks.
