Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 726

How does a WLC achieve stateful switchover for APs and clients?

Answer options

• A. The active WLC establishes a CAPWAP tunnel to the AP, and the standby WLC establishes a LWAPP tunnel to the AP.
• B. The active WLC establishes a CAPWAP tunnel with the AP, and the standby WLC copies the AP database and the client database from the active WLC.
• C. The active WLC establishes a CAPWAP tunnel with the AP and standby WLC to share the AP database information.
• D. The active and standby WLCs establish separate CAPWAP tunnels to the AP.

Correct answer: B

Explanation

The correct answer is B because the standby WLC needs to have the latest information about the AP and its clients to ensure a seamless transition during a failover. Options A and C incorrectly describe the type of tunnel or the process of sharing database information, while option D does not address the need for the standby to have updated databases.
