Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 177

Based on a wireless network design, an engineer configured a primary and secondary controller for their APs. A power interruption caused the primary Cisco WLC to go down, and, as expected, all APs joined the secondary controller. When the primary controller came back up, all the APs remained joined to the secondary controller. Which approach must the engineer take for the APs to move back to the primary?

Answer options

• A. Set AP Failover Priority to 4 on each AP.
• B. Set AP Fallback to Enabled on the secondary controller.
• C. Set AP Fallback to Enabled on the primary controller.
• D. Set AP Failover Priority to Critical globally.

Correct answer: C

Explanation

The correct choice is C because enabling AP Fallback on the primary controller allows the APs to revert back to it once it's available again. Options A and D do not facilitate the return of APs to the primary controller in this situation, and option B only affects the secondary controller without addressing the primary's role.
