HPE Aruba Certified Campus Access Associate (ACAA) — Question 6

An organization owns a fully functional multi-controller Aruba network with a Virtual Mobility Master (VMM) in VLAN20. They have asked a network consultant to deploy a redundant MM on a different server. The solution must offer the lowest convergence time and require no human interaction in case of failure.
The servers host other virtual machines and are connected to different switches that implement ACLs to protect them. The organization grants the network consultant access to the servers only, and appoints a network administrator to assist with the deployment.
What must the network administrator do so the network consultant can successfully deploy the solution? (Choose two.)

Answer options

• A. Allocate VLAN20 to the second server, and extend it throughout the switches, then reserve one IP address for the second MM and another IP address for its gateway.
• B. Allocate VLAN20 to the second server, and permit routing between them, then reserve one IP address for the second MM and another IP address for its gateway.
• C. Configure an ACL entry that permits IP protocol 50, UDP port 500, and multicast IP 224.0.0.18.
• D. Allocate VLAN20 to the second server, and extend it throughout the switches, then reserve one IP address for the second MM and another for the VIP.
• E. Configure an ACL entry that permits UDP 500, TCP 4500, and multicast IP 224.0.0.5.

Correct answer: A, E

Explanation

Option A is correct as it ensures the second server is on the same VLAN and assigns necessary IP addresses for the MM and its gateway, facilitating the deployment of the redundant MM. Option E is also correct because it allows necessary UDP and TCP traffic for the MM to function correctly. The other options either do not address the VLAN configuration properly or do not allow the essential traffic needed for the deployment.
