HPE Aruba Certified Mobility Associate (ACMA) — Question 46

An architect has an Instant AP (IAP) cluster at a mid-sized branch office. The IAP cluster now needs to tunnel corporate traffic to a Mobility Controller (MC) at the main office. However, the branch office should remain functional even if the link to the main office fails. Users at the branch office require access to main office resources, but do not require multicast services.
What is the recommended DHCP mode?

Answer options

• A. Local
• B. Centralized L2
• C. Distributed L2
• D. Distributed L3

Correct answer: D

Explanation

The correct choice is Distributed L3 because it allows branch office users to access resources at the main office while ensuring that the branch remains operational if the link to the main office goes down. Local and Centralized L2 modes would not provide the necessary functionality for maintaining access during a link failure, and Distributed L2 is less suitable as it does not support the required routing capabilities for this scenario.
