HPE Aruba Certified Mobility Expert (ACMX) — Question 35

An administrator creates a cluster of four Mobility Controllers (MCs). When the administrator verifies the cluster operation, the administrator notices that it is operating as an L3-connected cluster.
What should the administrator do to ensure that the cluster operates as an L2-connected cluster? (Choose two.)

Answer options

• A. Include all IP addresses in the same subnets shared by the Mobility Controllers.
• B. Exclude all VLANs that are not trunked to each Mobility Controller.
• C. Verify VLAN configuration on the switch trunks that interconnects the Mobility Controllers.
• D. Configure a separate VRRP group for each cluster member.
• E. Ensure that the controller IP addresses are in the same subnet.

Correct answer: B, E

Explanation

To achieve an L2-connected cluster, it is essential to exclude any VLANs that are not trunked to the Mobility Controllers (Option B), as this ensures proper communication at Layer 2. Additionally, the controller IP addresses must be in the same subnet (Option E) to facilitate L2 connectivity. The other options either do not directly affect the L2 connectivity or are unnecessary for this configuration.
