A company issues user certificates to domain computers using its Windows CA and the default user certificate template. You have set up HPE Aruba Networking ClearPass Policy Manager (CPPM) to authenticate 802.1X clients with those certificates. However, during tests, you receive an error that authorization has failed because the usernames do not exist in the authentication source.

What is one way to fix this issue and enable clients to successfully authenticate with certificates?

  1. Configure rules to strip the domain name from the username.
  2. Change the authentication method list to include both PEAP MSCHAPv2 and EAP-TLS.
  3. Add the ClearPass Onboard local repository to the authentication source list.
  4. Remove EAP-TLS from the authentication method list and add TEAP there instead.

Answer(s): A

Explanation:

To fix the issue where authorization fails because the usernames do not exist in the authentication source, you can configure rules in HPE Aruba Networking ClearPass Policy Manager (CPPM) to strip the domain name from the username.
When certificates are issued by a Windows CA, the username in the certificate often includes the domain (e.g., user@domain.com). ClearPass might not be able to find this format in the authentication source. By stripping the domain name, you ensure that ClearPass searches for just the username (e.g., user) in the authentication source, allowing successful authentication.


Reference:

ClearPass configuration guides and documentation on certificate-based authentication detail the process of modifying and normalizing usernames to ensure successful authentication against authentication sources.



You need to use "Tips:Posture" conditions within an 802.1X service's enforcement policy.

Which guideline should you follow?

  1. Enable caching roles and posture attributes from previous sessions in the service's enforcement settings.
  2. Create rules that assign postures in the service's role mapping policy.
  3. Enable profiling in the service's general settings.
  4. Select the Posture Policy type for the service's enforcement policy.

Answer(s): A

Explanation:

When using "Tips
" conditions within an 802.1X service's enforcement policy, you should enable caching roles and posture attributes from previous sessions in the service's enforcement settings. This ensures that ClearPass retains posture information from previous authentications, which is necessary for making decisions based on the current posture state of an endpoint. By caching these attributes, ClearPass can apply appropriate enforcement actions based on the device's posture status.


Reference:

Aruba ClearPass documentation provides guidelines on configuring enforcement policies and using posture attributes effectively, including the importance of caching for maintaining posture information across sessions.



You have created this rule in an HPE Aruba Networking ClearPass Policy Manager (CPPM) service's enforcement policy: IF Authorization [Endpoints Repository] Conflict EQUALS true THEN apply "quarantine_profile"

What information can help you determine whether you need to configure cluster-wide profiler parameters to ignore some conflicts?

  1. Whether the company has rare Internet of Things (loT) devices
  2. Whether some devices are incapable of captive portal or 802.1X authentication
  3. Whether the company has devices that use PXE boot
  4. Whether some devices are running legacy operating systems

Answer(s): C

Explanation:

When you have created a rule in a ClearPass Policy Manager (CPPM) service's enforcement policy to quarantine devices with endpoint conflicts, it is important to consider whether the company has devices that use PXE boot. PXE booting devices can create conflicts in the profiler because they may temporarily have different network attributes (e.g., MAC address or IP address) before fully booting and obtaining their final configuration. Understanding whether PXE boot is in use can help determine if profiler parameters need to be adjusted to ignore such temporary conflicts, ensuring that devices are not incorrectly quarantined.


Reference:

ClearPass profiler configuration documentation and best practices include considerations for handling network devices with dynamic or temporary configurations, such as those using PXE boot.



A company has HPE Aruba Networking APs, which authenticate users to HPE Aruba Networking ClearPass Policy Manager (CPPM).

What does HPE Aruba Networking recommend as the preferred method for assigning clients to a role on the AOS firewall?

  1. Configure CPPM to assign the role using a RADIUS enforcement profile with a RADIUS:IETF Username attribute.
  2. Configure CPPM to assign the role using a RADIUS enforcement profile with an Aruba-User-Role VSA.
  3. OCreate server rules on the APs to assign clients to roles based on RADIUS IETF attributes returned by CPPM.
  4. Create user rules on the APs to assign clients to roles based on a variety of criteria.

Answer(s): B

Explanation:

The preferred method for assigning clients to a role on the AOS firewall is to configure HPE Aruba Networking ClearPass Policy Manager (CPPM) to assign the role using a RADIUS enforcement profile with an Aruba-User-Role VSA (Vendor-Specific Attribute). This method allows ClearPass to dynamically assign the appropriate user roles to clients during the authentication process, ensuring that role-based access policies are consistently enforced across the network.


Reference:

Aruba ClearPass documentation and RADIUS configuration guides provide detailed instructions on setting up RADIUS enforcement profiles and using the Aruba-User-Role VSA for role assignment.
