Question:
Which action is necessary to provide encrypted transfer of data between a RADIUS server and a AAA-enabled router?
- Configure the preshared key exactly the same way on the server and the router.
- Encrypt usernames and passwords that will be used between the router and the RADIUS server.
- Use identical reserved ports on the server and the router.
- Create a VPN tunnel between the server and the router.
Explanation: The key command configures the preshared key on a RADIUS server that is used for encryption. The keys must be identical on the router and on the RADIUS server. The creation of a VPN tunnel is unnecessary. The configuration of ports does not have any effect on encryption.
