HPE Aruba Certified Mobility Associate (ACMA) — Question 16

A customer has very high availability requirements for wireless services. The architect plans to implement clustering on several Aruba Mobility Controllers (MCs).
Which benefit of this feature should the architect explain?

Answer options

• A. Clustering provides wireless client load balancing and seamless failover for client sessions.
• B. Clustering provides high stability because one MC is active for all sessions and one is standby for all sessions.
• C. Clustering enables an AP with a failed MC to operate on its own briefly to ensure seamless connectivity.
• D. Clustering enables an AP with a failed MC to reconnect to a new AP after a short bootstrap.

Correct answer: B

Explanation

The correct answer is B because clustering ensures that one Mobility Controller (MC) handles all sessions while another acts as a standby, providing high stability. The other options describe features related to load balancing, temporary operation, and reconnection, but do not emphasize the stability aspect provided by the active-standby configuration.
