Answer : C

According to the ClearPass Policy Manager User Guide1, the tag shown in the exhibit is a Device Insight tag, which is used to classify and identify devices based on their behavior and characteristics. Device Insight tags can be used as conditions in enforcement policies to apply different actions or roles to devices based on their tags. However, in order to ensure that devices are reclassified and receive the correct treatment based on their tags, profiling must be enabled in each service that uses one of these enforcement profiles. Profiling is a feature that allows ClearPass to dynamically discover and profile devices on the network, and update their attributes and tags accordingly. Profiling also allows ClearPass to send RADIUS Change of Authorization (CoA) messages to the network access servers (NASes) that control the access of the devices, and instruct them to reauthenticate or terminate the sessions of the devices that have changed their tags. The profiling action must be set to the correct one for the NASes using that service, as different NASes may support different types of CoA messages. Therefore, option C is the correct answer.

Answer : D

According to the AOS-CX Switches Multiple Vulnerabilities1, one of the vulnerabilities (CVE-2021-41001) affects the Telnet service on AOS-CX switches. This vulnerability allows an unauthenticated remote attacker to cause a denial-of-service condition on the switch by sending specially crafted Telnet packets. The impact of this vulnerability is high, as it could result in a loss of management access and network disruption. Therefore, one immediate remediation that you should recommend is to disable Telnet on the switch. This way, the switch can prevent any malicious Telnet traffic from reaching it and avoid the exploitation of this vulnerability.

Answer : D

According to the AOS-CX Switches Multiple Vulnerabilities1, one of the vulnerabilities (CVE-2021-41000) affects the SSH service on AOS-CX switches. This vulnerability allows an unauthenticated remote attacker to cause a denial-of-service condition on the switch by sending specially crafted SSH packets. The impact of this vulnerability is high, as it could result in a loss of management access and network disruption. Therefore, one recommendation to make is to create a control plane ACL to limit the sources that can access the switch with SSH. This way, the switch can filter out unwanted or malicious SSH traffic and reduce the risk of exploitation.

Answer : D

According to the Aruba Cloud Authentication and Policy Overview1, Device Insight tags are stored in the Endpoint Repository and can be used as conditions within CPPM role mapping or enforcement policy rules. The rule condition type should be Endpoint, and the attribute should be Device Insight Tags. No extra authorization source is required for services that use policies with these rules. Therefore, option D is the correct answer.

Option A is incorrect because creating an HTTP authentication source to the Central API is not necessary to use Device Insight tags as conditions. Device Insight tags are already synchronized between Central and CPPM, and can be accessed from the Endpoint Repository.

Option B is incorrect because using the Application type for the rule conditions is not applicable to Device Insight tags. The Application type is used to match attributes from the Application Authentication source, which is used to integrate with third-party applications such as Microsoft Intune or Google G Suite.

Option C is incorrect because using the Endpoints Repository type for the rule conditions is not valid for Device Insight tags. The Endpoints Repository type is used to match attributes from the Endpoints Repository source, which is different from the Endpoint type. The Endpoints Repository source contains information about endpoints that are manually added or imported into CPPM, while the Endpoint type contains information about endpoints that are dynamically discovered and profiled by CPPM or Device Insight. Adding Endpoints Repository as a secondary authentication source for services that use policies with these rules is also unnecessary and redundant.

Answer : B

A custom NAE script is a Python script that defines the monitors, the alert-trigger logic, and the remedial actions for an NAE agent. A monitor is a URI that specifies the data source and the data type that the NAE agent should collect and analyze. For example, to monitor the ARP inspection statistics on a VLAN, the monitor URI would be something like this:

where <vlan-id> is the ID of the VLAN to be monitored.

To allow the admins to select the correct VLAN ID for the agent to monitor when they create the agent, you need to define a VLAN ID parameter in the NAE script. A parameter is a variable that can be set by the user when creating or modifying an agent. A parameter can be referenced in other parts of the script by using the syntax ${parameter-name}. For example, to define a VLAN ID parameter and reference it in the monitor URI, you would write something like this:

This way, when the admins create or modify the agent, they can enter the VLAN ID that they want to monitor, and the NAE script will use that value in the monitor URI.

You can find more information about how to write custom NAE scripts and use parameters in theNAE Scripting Guide
