Important HPE6-A88 Exam Questions

Answer: C

Explanation:

OCSP (Online Certificate Status Protocol) is designed to provide real-time revocation status. If an OCSP responder returns a status of 'unknown', it means the responder has no record of the certificate. From a security standpoint, ClearPass treats any response other than 'Good' as a failure. To prevent potential unauthorized access via certificates that the PKI cannot verify, ClearPass will reject the authentication attempt.

Answer: B

Explanation:

The LDAP browser within ClearPass Policy Manager is a critical diagnostic tool used to verify the actual data stored in an external identity store. Because ClearPass bases its Authorization decisions on specific attributes (such as department, memberOf, or accountStatus), the administrator must ensure those attributes are correctly populated in the directory. By browsing the directory tree and inspecting a specific user object, an engineer can see exactly what attributes ClearPass 'sees' during a request, helping identify if a role-mapping failure is due to a missing or incorrect LDAP attribute.

Answer: A

Explanation:

Even if a specialized authentication method (like EAP-TLS with OCSP) is configured globally in ClearPass, it is not active for a specific request until it is assigned to a Service. The administrator must navigate to the service being used for that network access and explicitly add the desired method to the Authentication Methods list. Without this step, ClearPass will not attempt to use that specific protocol logic when processing incoming requests for that service.

Answer: B

Explanation:

Entity Update allows ClearPass to write custom attributes back to its own Endpoint database. Once a device is tagged as 'Corporate,' this attribute becomes part of the context available to all services. When that device connects to a 'Guest' SSID, the Guest Service can include a rule that checks for the 'Corporate' tag; if found, the service uses an Enforcement Policy to return a 'Deny Access' profile, successfully segmenting corporate assets from the guest network.

Answer: A

Explanation:

To differentiate security levels based on device type (e.g., giving a VoIP phone different access than a laptop), ClearPass must use Profiling. The service first identifies the device type using various collectors and then evaluates this information in the Enforcement Policy. This allows the administrator to select specific Enforcement Profiles (VLANs/ACLs) that are dynamically assigned based on the high-fidelity profile data gathered at connection time.
