HPE7-A02 Online Practice Questions

Explanation:

Explanation:
To follow best security practices for 802.1X authentication settings in Windows domain clients:
Specify at least two server names under "Connect to these servers":
Admins should explicitly list trusted RADIUS server names (e.g., radius.example.com) to prevent the client from connecting to unauthorized or rogue servers.
This mitigates man-in-the-middle (MITM) attacks where an attacker attempts to present their own RADIUS server.
Select the desired Trusted Root Certificate Authority and "Don't prompt users":
Select the Trusted Root CA that issued the RADIUS server's certificate. This ensures clients validate the correct server certificate during the EAP-TLS/PEAP authentication process.
Enabling "Don't prompt users" ensures end users are not confused or tricked into accepting certificates from untrusted servers.
Why the other options are incorrect:
Option C: Incorrect. Wildcards in server names (e.g., *.example.com) weaken security and allow broader matching, increasing the risk of rogue servers.
Option D: Incorrect. Clearing "Use simple certificate selection" requires users to select certificates manually, which can lead to errors and usability issues. Simple certificate selection is recommended when properly configured.
Recommended Settings for Best Security Practices:
Server Validation: Specify the exact RADIUS server names in the "Connect to these servers" field.
Root CA Validation: Ensure only the correct Trusted Root Certificate Authority is selected.
User Prompts: Enable "Don't prompt users" to enforce automatic and secure authentication without user intervention.

Explanation:
Centralized Role Configuration on CPPM:
CPPM can assign roles to clients dynamically during authentication.
However, the actual ACL policies (e.g., firewall policies) must already exist and be referenced locally on the switch.
CPPM cannot directly configure ACL details on AOS-CX switches.
Option Analysis:
Option A: Correct. The role is defined on CPPM, but it references a policy pre-configured on the switch.
Option B: Incorrect. This does not align with Aruba's centralized role-based access control design.
Option C: Incorrect. CPPM cannot configure the ACL policies and classes directly; they must exist locally.
Option D: Incorrect. Policies can be referenced centrally but not fully configured on CPPM.

Explanation:
To better interpret the packets shown in the Wireshark capture, you should choose to decode UDP port 5555 packets as ARUBA_ERM and set the Aruba ERM Type to 0. This configuration will allow Wireshark to properly decode and display the Aruba-specific encapsulated remote mirroring (ERM) packets, providing a clearer understanding of the traffic.

Explanation:
To enforce 802.1X authentication for Windows domain computers to HPE Aruba Networking ClearPass Policy Manager (CPPM) and have the computers authenticate as both machines and users in the same session, you should set up TEAP (Tunneled EAP) as the authentication method. TEAP supports both machine and user authentication within a single 802.1X session, making it suitable for scenarios where both types of authentication are required simultaneously.
Reference: Aruba ClearPass configuration guides provide detailed instructions on setting up TEAP for environments requiring combined machine and user authentication.
