Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 133

An engineer needs a wireless design to provide redundancy for APs at remote sites that are connected to Cisco 3504 Wireless LAN Controllers. The central Cisco 5520 Wireless LAN Controller supports 2000 APs and has 1975 access points associated to it. The engineer decides that not all APs at the remote sites must remain functional in the event of a failure. How does the engineer ensure that the most important access points at the remote sites remain online while not impacting the main site?

Answer options

• A. Enable Global AP Failover Priority, set the 1975 APs to a priority of "high", and set the 25 most important APs at the remote sites to "critical".
• B. Enable AP Fallback Mode, set the 1975 APs to a priority of "high", and set the 25 most important APs at the remote sites to "critical".
• C. Enable Global AP Failover Priority, leave the 1975 APs at the default priority, and set the most important APs at the remote sites to "low".
• D. Enable AP Fallback Mode, leave the 1975 APs at the default priority, and set the most important APs at the remote sites to "high".

Correct answer: A

Explanation

The correct choice is A because enabling Global AP Failover Priority allows for the prioritization of APs, ensuring that the most critical ones at remote sites remain operational during failures. Option B is incorrect as AP Fallback Mode does not provide the required priority management. Options C and D do not prioritize the APs correctly, resulting in the most important APs potentially being offline during a failure.
