C. device-administration packets are encrypted in their entirely.
D. It allows the user to remotely access devices from other vendors.
E. It allows the users to be authenticated against a remote server.
F. It supports access-level authorization for commands.
Correct Answer: CEF
TACACS+ (and RADIUS) allow users to be authenticated against a remote server -> E is correct.
TACACS+ encrypts the entire body of the packet but leaves a standard TACACS+ header -> C is correct.
TACACS+ supports access-level authorization for commands. That means you can use commands to assign privilege levels on the router -> F is correct.
By default, there are three privilege levels on the router.
+ privilege level 1 = non-privileged (prompt is router>), the default level for logging in
+ privilege level 15 = privileged (prompt is router#), the level after going into enable mode
+ privilege level 0 = seldom used, but includes 5 commands: disable, enable, exit, help, and logout
