Runtime protection monitors and protects a container after deployment while its processes are executing. This is the stage at which attempted exploitation, unexpected process behavior, vulnerable packages, configuration weaknesses, and policy violations can become active threats. Cisco describes cloud workload protection as defending containers and other workloads against runtime threats, misconfigurations, and vulnerabilities. Consequently, option C directly matches the requirement. Control groups are a Linux resource-management mechanism; they limit or account for CPU, memory, and other resources but are not a complete security capability. Separation of duties is an administrative control that reduces excessive privilege in development and operations. Cloud-native firewalling controls network flows, but it does not by itself observe or stop every malicious action inside a running container. Cisco’s cloud workload protection overview confirms the runtime distinction.

 Cisco AMP for Endpoints provides next-generation protection by leveraging an endpoint protection platform (EPP) and endpoint detection and response (EDR) capabilities. EPP is a set of multifaceted prevention techniques that stop threats from compromising endpoints, such as behavioral analytics, machine learning, and signature-based methods. EDR is a set of powerful features that reduce the attack surface and remediate faster, such as advanced threat hunting, endpoint isolation, and dynamic malware analysis. Cisco AMP for Endpoints also integrates with SecureX, a built-in platform that offers extended detection and response (XDR) capabilities across multiple control points, such as network, cloud, email, and web. By combining EPP, EDR, and XDR, Cisco AMP for Endpoints delivers a comprehensive and resilient endpoint security solution that can detect, respond, and recover from sophisticated attacks. References:

The decisive message is TS_UNACCEPTABLE, followed by “Traffic selector negotiation failed.” During IKEv2 CHILD_SA creation, the peers negotiate traffic selectors defining the protected local and remote address ranges. RFC 7296 defines TS_UNACCEPTABLE as indicating that the proposed traffic selectors are unacceptable. The displayed encryption, integrity, and PFS parameters do not produce an algorithm-rejection notification; Phase 1 has already completed, and the failure occurs while negotiating selectors for the CHILD_SA. The engineer must make the protected-network definitions complementary on both FTD peers—for example, one peer’s local network must equal the other peer’s remote network, with compatible masks. Changing AES, extending the IKE lifetime, or removing the PFS group does not correct mismatched encryption domains. RFC 7296—IKEv2

Configuring the IEEE 802.1X Flexible Authentication feature to support Layer 3 authentication mechanisms involves adding MAC Authentication Bypass (MAB) into the switch configuration. This allows devices that do not support 802.1X to be authenticated using their MAC address. Once MAB identifies the device, it can then be redirected to a Layer 3 device for further authentication, thus providing a mechanism to support devices requiring Layer 3 authentication methods.

Cisco FTDv in AWS can be deployed in two different deployment models: single-instance and cluster. In both models, the FTDv can be configured in routed mode and managed by either an FMCv installed in AWS or a physical FMC appliance on premises. The FTDv can also use Geneve encapsulation for traffic interfaces to support AWS Gateway Load Balancer (GWLB) integration. The following table summarizes the supported deployment model configurations for FTDv in AWS:

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

Patching helps to mitigate vulnerabilities by applying fixes or updates to software or firmware that have known security flaws. Vulnerabilities can be exploited by cybercriminals to compromise the confidentiality, integrity, or availability of the IT systems and data. Patching endpoints consistently reduces the risk of cyberattacks and data breaches by closing the gaps that attackers can use to gain unauthorized access or cause damage. Patching also improves the performance and functionality of the IT systems by addressing bugs or errors12.

Option B is the correct answer, as it explains the main benefit of patching endpoints consistently. Option A is incorrect, as patching does not necessarily reduce the attack surface of the infrastructure, which is the total number of possible entry points for an attacker. Patching only addresses the existing vulnerabilities in the software or firmware, but does not eliminate the attack surface itself. Option C is incorrect, as patching is not always required per the vendor contract, although some vendors may provide support or incentives for patching. Option D is incorrect, as patching does not allow for creating a honeypot, which is a decoy system that is intentionally left vulnerable to lure and trap attackers. References: Patch Management Overview, Challenges, and Recommendations. Patch Management Explained: Challenges, Best Practices & Steps.

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:

In XSS, an attacker will try to inject his malicious code (usually malicious links) into a database. When other users follow his links, their web browsers are redirected to websites where attackers can steal data from them. In a SQL Injection, an attacker will try to inject SQL code (via his browser) into forms, cookies, or HTTP headers that do not use data sanitizing or validation methods of GET/POST parameters.

The login block-for command sets a limit on the maximum number of failed login attempts allowed within a defined period of time. If this limit is exceeded, no further logins are allowed for the specified period of time. This feature is designed to protect the router from denial-of-service and dictionary attacks. The syntax of the command is as follows:

login block-for < block-time-period > attempts < fail-attempts > within < login-attempt-time-period >

The  < block-time-period >  parameter specifies the duration of the quiet period in seconds. The  < fail-attempts >  parameter specifies the number of failed attempts that trigger the quiet period. The  < login-attempt-time-period >  parameter specifies the time window in seconds for counting the failed attempts.

In this question, the command login block-for 100 attempts 4 within 60 means that if four failures occur in 60 seconds, the router goes to quiet mode for 100 seconds. During the quiet period, no login attempts are accepted, and the router responds with the message “Login disabled for < block-time-period > seconds due to too many failed login attempts.” After the quiet period expires, the router resumes normal login operations.

The other options are incorrect because they do not match the command syntax or the expected behavior of the login block-for feature.

Explanation

NetFlow is typically used for several key customer applications, including the following:

…

Billing and accounting. NetFlow data provides fine-grained metering (for instance, flow data includes details such as IP addresses, packet and byte counts, time stamps, type of service (ToS), and application ports) for highly flexible and detailed resource utilization accounting. Service providers may use the information for billing based on time of day, bandwidth usage, application usage, quality of service, and so on. Enterprise customers may use the information for departmental charge back or cost allocation for resource utilization.

Explanation

The logging of your identities’ activities is set per-policy when you first create a policy. By default, logging is on and set to log all requests an identity makes to reach destinations. At any time after you create a policy, you can change what level of identity activity Umbrella logs.

From the Policy wizard, log settings are:

Log All Requests—For full logging, whether for content, security or otherwise

Log Only Security Events—For security logging only, which gives your users more privacy—a good setting for people with the roaming client installed on personal devices

Don’t Log Any Requests—Disables all logging. If you select this option, most reporting for identities with this policy will not be helpful as nothing is logged to report on.

Explanation

Symmetric encryption uses a single key that needs to be shared among the people who need to receive the message while asymmetric encryption uses a pair of public key and a private key to encrypt and decrypt messages when communicating.

Asymmetric encryption takes relatively more time than the symmetric encryption.

Diffie Hellman algorithm is an asymmetric algorithm used to establish a shared secret for a symmetric key

algorithm. Nowadays most of the people uses hybrid crypto system i.e, combination of symmetric and

asymmetric encryption. Asymmetric Encryption is used as a technique in key exchange mechanism to share secret key and after the key is shared between sender and receiver, the communication will take place using symmetric encryption. The shared secret key will be used to encrypt the communication.

Triple DES (3DES), a symmetric-key algorithm for the encryption of electronic data, is the successor of DES (Data Encryption Standard) and provides more secure encryption then DES.

Note: Although “requires secret keys” option in this question is a bit unclear but it can only be assigned to

Symmetric algorithm.
