Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 103

What is the responsibility of a secondary WLC?

Answer options

• A. It enables Layer 2 and Layer 3 roaming between itself and the primary controller.
• B. It registers the LAPs if the primary controller fails.
• C. It avoids congestion on the primary controller by sharing the registration load on the LAPs.
• D. It shares the traffic load of the LAPs with the primary controller.

Correct answer: B

Explanation

The correct answer is B because the secondary WLC is designed to take over LAP registration when the primary controller is unavailable. Options A, C, and D discuss features related to roaming and load balancing but do not accurately describe the specific function of registering LAPs during a primary controller failure.
