Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 700

A Cisco administrstor deploys a new wireless network but CAPWAP APs cannot communicate with the wireless controller. IP connectivity in the network functions properly. Which action resolves the issue?

Answer options

• A. Open CAPWAP UDP port 12222 in the network firewall.
• B. Open CAPWAP UDP ports 5246 and 5247 in the network firewall.
• C. Enable the UDP Lite feature on the WLC.
• D. Ensure that the controller is connected to a AAA server.

Correct answer: B

Explanation

The correct answer is B because CAPWAP uses UDP ports 5246 and 5247 for control and data traffic between the access points and the controller. Opening port 12222 (option A) is not relevant for CAPWAP communication, while enabling UDP Lite (option C) and ensuring the controller's connection to a AAA server (option D) do not address the communication issue directly.
