HPE Aruba Certified Design Expert (ACDX) — Question 4

For which use should network administrators set up Aruba access points (APs) as multi-zone APs?

Answer options

• A. The company requires high availability for its wireless services, and APs must be able to be controlled by more than once Mobility Controller (MC) in case a controller fails.
• B. The company has multiple small offices where APs at each branch office must forward internet traffic locally and corporate traffic over a secure tunnel to a centralized Mobility Controller (MC).
• C. The company has some devices that support both 5GHz and 2.4 GHz, and the APs must operate in both frequency bands.
• D. The company has a Mobility Manager (MM)-based solution that requires APs to terminate to multiple controllers that reside in different administrative domains.

Correct answer: D

Explanation

The correct answer is D because multi-zone APs are necessary when the Mobility Manager (MM) requires APs to connect to multiple controllers across various administrative domains. The other options describe scenarios that do not specifically require multi-zone functionality: option A focuses on high availability, option B on local traffic handling, and option C on frequency band support.
