HPE Aruba Certified Mobility Expert (ACMX) — Question 9

A Microsoft RADIUS server is used to centralize AAA functions by a company. Upon a successful authentication lookup performed by an Aruba Mobility Controller
(MC), the administrator wants to have the RADIUS server pass back the correct post-authentication role name that the controller should apply to the users traffic.
Which additional task must the administrator perform for the controllers configuration to implement this process?

Answer options

• A. Install ClearPass’s VSA file on the controller.
• B. Install Microsoft’s VSA file on the controller.
• C. Configure the server-derived rules on the controller.
• D. Enable AAA on the controller.

Correct answer: A

Explanation

The correct answer is A, as installing ClearPass’s VSA file on the controller allows the controller to interpret the role information sent by the RADIUS server. Option B is incorrect because installing Microsoft’s VSA file does not provide the necessary role mapping functionality required. Option C is not correct since configuring server-derived rules alone does not ensure that the correct role name is communicated. Option D is also incorrect because enabling AAA does not specifically address the need for role name mappings.
