HPE Aruba Certified Mobility Expert (ACMX) — Question 33

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 B. Users at Campus A successfully authenticate and connect to the Campus A wireless network. However, when users from Campus B visit Campus
A they fail authentication.
What can the administrator do to solve this problem?

Answer options

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

Correct answer: A

Explanation

Enabling FastConnect on the Campus A Mobility Controllers allows for seamless authentication across different campuses by facilitating the use of multiple RADIUS servers. The other options do not address the cross-campus authentication issue, as machine authentication and EAP configurations do not resolve the need for proper server communication between the two campuses.
