Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 32

An engineer must configure the virtual IP address on multiple controllers in a mobility group. Which rule must the engineer follow to ensure proper roaming?

Answer options

• A. Ensure that the DNS entry is tied to the virtual IP address of the WLC.
• B. Use a unique IP address for each WLC.
• C. Ensure that the DNS Host Name field is defined.
• D. Use the same IP address for each WLC.

Correct answer: D

Explanation

The correct answer is D because using the same IP address for each Wireless LAN Controller (WLC) allows for seamless roaming within the mobility group. Options A, B, and C are incorrect as they do not ensure that roaming works effectively; having unique IP addresses or needing DNS configurations does not support the required functionality for roaming in this context.
