Implementing Secure Solutions with Virtual Private Networks (SVPN) — Question 53

A network engineer has set up a FlexVPN server to terminate multiple FlexVPN clients. The VPN tunnels are established without issue. However, when a Change of Authorization is issued by the RADIUS server, the FlexVPN server does not update the authorization of connected FlexVPN clients. Which action resolves this issue?

Answer options

• A. Add the aaa server radius dynamic-author command on the FlexVPN clients.
• B. Fix the RADIUS key mismatch between the RADIUS server and FlexVPN server.
• C. Add the aaa server radius dynamic-author command on the FlexVPN server.
• D. Fix the RADIUS key mismatch between the RADIUS server and FlexVPN clients.

Correct answer: C

Explanation

The correct action is to add the aaa server radius dynamic-author command on the FlexVPN server, as this enables the server to accept and process Change of Authorization requests. The other options either address mismatches or apply configurations incorrectly on the clients rather than the server, which does not resolve the authorization update issue.
