HPE Aruba Certified Mobility Expert (ACMX) — Question 32

What must an administrator configure in order for the ClearPass server to execute a RADIUS Change of Authorization (CoA) to Aruba Mobility Controllers (MCs) in a cluster?

Answer options

• A. Active and Standby AAC with clustering
• B. VRRP IP on each cluster member
• C. IPSec High Availability (HA) between two cluster members
• D. Primary and backup LMS IP addresses

Correct answer: C

Explanation

The correct answer is C, as IPSec High Availability (HA) is required to ensure secure communication and redundancy between cluster members for RADIUS CoA. Options A and B do not specifically address the CoA requirement, while D refers to LMS IP addresses which are not directly related to the CoA process.
