Which action resolves this issue?

Refer to the exhibit.

AAA server 10.1.1.1 is configured with the default authentication and accounting settings, but the switch cannot communicate with the server.

Which action resolves this issue?
A . Correct the timeout value
B . Match the authentication port
C . Correct the shared secret
D . Match the accounting port

Answer: B

Explanation

By default, RADIUS uses UDP port 1812 for authentication and port 1813 for accounting. In the exhibit above we see port 1814 is being used for authentication to AAA server at 10.1.1.1 which is not the default port so we must adjust the authentication port to the default value 1812.
