HPE Aruba Certified Network Security Associate (ACNSA) — Question 86

An administrator supports Aruba Mobility Controllers (MCs) managed by a Mobility Master (MM) in a non-cluster deployment. The administrator performs these tasks on the MM for the MCs:

• Enables L3 IP mobility for the respective VAPs on the MCs
• Creates a L3 domain and places the MCs in the domain

However, roaming does not work when users roam from an AP connected to one controller in the domain to an AP connected to a different controller in the domain.

What must the administrator do to fix this problem?

Answer options

• A. Configure the same VLANs on the Mobility Controllers in the L3 domain.
• B. Re-provision the APs associated with the Mobility Controllers.
• C. Enable L3 IP Mobility globally on the Mobility Controllers.
• D. Create a home-agent-to-foreign-agent mapping table.

Correct answer: D

Explanation

The correct answer is D because creating a home-agent-to-foreign-agent mapping table is essential for enabling proper communication and roaming between different controllers in a L3 domain. Options A, B, and C do not address the specific requirement for user roaming between APs on different controllers, making them ineffective solutions to this problem.
