HPE Aruba Certified Network Security Associate (ACNSA) — Question 2

An administrator at Campus A manages Aruba Mobility Controllers (MCs). The administrator defines a server group that includes a local ClearPass server and a remote Microsoft RADIUS server. The ClearPass server has the credentials for users at Campus A and the Microsoft RADIUS server has the credentials for users at Campus Ð’. Users at Campus A successfully authenticate and connect to the Campus A wireless network. However, when users from Campus Ð’ visit Campus
A they fail authentication.
What can the administrator do to solve this problem?

Answer options

• A. Enable EAP termination on the ClearPass server.
• B. Enable machine authentication on the Mobility Controllers.
• C. Enable EAP-TTLS with EAP Termination on the Mobility Controllers.
• D. Enable FastConnect on the Campus A Mobility Controllers.

Correct answer: B

Explanation

The correct answer is B, as enabling machine authentication on the Mobility Controllers allows for authentication of devices from Campus Ð’, which resolves the issue of them failing to connect. Options A and C do not address the root cause of the authentication failure for users from Campus Ð’, while D, enabling FastConnect, does not specifically solve the issue of user authentication from the remote campus.
