Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 208

A network engineer must design a new Cisco wireless solution that contains three Cisco 9800-40 WLCs. WLC1 and WLC2 will be combined into one logical unit with SSO and a backup WLC named WLC3 will be joined by using a mobility tunnel. Link redundancy between the WLCs and the switches is required. Which WLCs must the design provide connectivity to the network equipment for LAG to be effective in an SSO failover scenario?

Answer options

• A. WLC1 and WLC2
• B. WLC2
• C. WLC1, WLC2, and WLC3
• D. WLC1

Correct answer: A

Explanation

The correct answer is A because for LAG (Link Aggregation Group) to function properly in an SSO (Stateful Switchover) failover scenario, both WLC1 and WLC2 need to be connected to the same network equipment. Option B is incorrect as it only mentions WLC2, while options C and D do not address the requirement for both WLC1 and WLC2 to ensure redundancy.
