HPE Aruba Certified Mobility Associate (ACMA) — Question 34

An architect plans to deploy a Mobility Controller (MC) at one building in subnet 10.23.01.0/24 and another MC in another building in subnet 10.44.12.0/24. The
MCs need to provide redundancy for each other. What must the architect take into account in the redundancy plan?

Answer options

• A. The MCs cannot provide any level of redundancy for each other unless one is moved into the other's subnet.
• B. The MCs cannot be in a cluster, and they must use Virtual Router Redundancy Protocol (VRRP) to provide redundancy for each other.
• C. The MCs can be in a cluster, but the cluster will not support features such as stateful failover.
• D. Each MC can be the backup LMS for the other MCs' APs, but it cannot be in a cluster with the other MC.

Correct answer: B

Explanation

Option B is correct because the MCs, being on different subnets, cannot be part of a cluster and must rely on VRRP for redundancy. Option A is incorrect as moving one MC is not the only solution for redundancy. Option C is wrong because clustering is not feasible in this scenario, and option D is misleading since being backup LMS does not imply they are clustered.
