Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 104

A customer has a single anchor WLC named Anchor A. Anchor A is in a DMZ and provides guest access. The customer wants to deploy an additional anchor controller named Anchor B to provide redundancy if Anchor A fails. Which design approach should be taken for the guest WLAN priority on the foreign WLC for each anchor WLC?

Answer options

• A. Set Anchor A to priority 3 and Anchor B to priority 3.
• B. Set Anchor A to priority 3 and Anchor B to priority 1.
• C. Set Anchor A to priority 1 and Anchor B to priority 1.
• D. Set Anchor A to priority 1 and Anchor B to priority 3.

Correct answer: D

Explanation

The correct setup is to assign Anchor A a priority of 1 and Anchor B a priority of 3, ensuring that if Anchor A fails, Anchor B is available as a backup with lower priority. Option A and B both assign equal or higher priority to Anchor A, which does not provide the intended redundancy. Option C gives both anchors the same priority, which also does not facilitate the desired failover mechanism.
