HPE Aruba Certified Network Security Associate (ACNSA) — Question 26

An administrator wants to implement a Live Upgrade (in-service upgrade) of a cluster in an Aruba wireless solution. Which ArubaOS feature does the Mobility
Master (MM) use to ensure RF redundancy, so that when one or more APs are rebooted there is no loss of wireless coverage for users?

Answer options

• A. AirMatch
• B. Mobility Controller load balancing
• C. AP image verification
• D. AP image preload

Correct answer: A

Explanation

The correct answer is AirMatch, which helps maintain RF redundancy by optimizing channel and power settings across the APs, ensuring users remain connected during upgrades. The other options, such as Mobility Controller load balancing and AP image verification, do not specifically address the RF redundancy needed during the in-service upgrade process.
