An administrator at Campus A manages Aruba Mobility Controllers (MCs). The administrator defines a server group that includes a local ClearPa

ss 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?

A. Enable FastConnect on the Campus A Mobility Controllers.

B. Enable machine authentication on the Mobili

ty Controllers.

C. Enable EAP-TTLS with EAP Termination on the Mobility Controllers.

D. Enable EAP termination on the ClearPass server.
