HP HPE7-A02 Exam With Confidence Using Practice Dumps

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.

To prevent rogue OSPF routers in the network shown in the exhibit, the preferred configuration on Switch-2 is to configure OSPF authentication on Lag 1 in MD5 mode. This setup enhances security by ensuring that only routers with the correct MD5 authentication credentials can participate in the OSPF routing process. This method protects the OSPF sessions against unauthorized devices that might attempt to introduce rogue routing information into the network.

1.OSPF Authentication: Implementing MD5 authentication on Lag 1 ensures that OSPF updates are secured with a cryptographic hash. This prevents unauthorized OSPF routers from establishing peering sessions and injecting potentially malicious routing information.

2.Secure Communication: MD5 authentication provides a higher level of security compared to simple password authentication, as it uses a more robust hashing algorithm.

3.Applicability: Lag 1 is the primary link between Switch-1 and Switch-2, and securing this link helps protect the integrity of the OSPF routing domain.

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.
