Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 169

A customer has multiple WLCs running in N+1 redundancy with APs load balanced between the WLCs. The customer performs AP failover testing between the WLCs and notices that some of the APs do not move back to their primary WLC after it recovers. What are two points that must be addressed in the design? (Choose two.)

Answer options

• A. DHCP Option 43 information is incorrect.
• B. APs do not have their secondary WLC information configured correctly.
• C. APs failover priorities are set to Low.
• D. AP Fallback is not enabled on one of the WLCs.
• E. APs do not have their primary WLC information configured correctly.

Correct answer: D, E

Explanation

The correct answers are D and E because AP Fallback must be enabled for APs to return to their primary WLC after it recovers, and APs need accurate primary WLC information to ensure they can connect back. Options A, B, and C do not directly impact the ability of APs to return to their primary WLC after failover.
