HPE Aruba Certified Mobility Associate (ACMA) — Question 14

An architect proposes an Aruba solution with a hardware Mobility Master (MM) to a customer. The customer has a disaster recovery site which is connected to the main site at Layer 3. The customer requires the MM to remain available in case of a total site failure.
Which plan meets the customer requirements?

Answer options

• A. Deploy a hardware MM to the disaster recovery site and set up VRRP between them.
• B. Deploy a hardware MM to the disaster recovery site and set its IP address as the standby master for MCs.
• C. Deploy the virtual MM (VMM) to the disaster recovery site and set the VMM IP address to the same address as the hardware MM.
• D. Deploy the virtual MM (VMM) to the disaster recovery site and configure clustering on the hardware and software appliances.

Correct answer: A

Explanation

Option A is correct because deploying a hardware MM at the disaster recovery site and using VRRP ensures that there is redundancy and failover capability in case of a site failure. Options B and C do not provide the necessary failover mechanism, as they either rely on a single master without redundancy or improperly configure the IP addresses. Option D does not address the specific requirement for maintaining availability in a total site failure scenario with proper failover techniques.
