In which three ways does the RADIUS protocol differ from TACACS? (Choose three.)

RADIUS uses UDP to communicate with the NAS.
RADIUS encrypts only the password field in an authentication packet.

RADIUS uses TCP to communicate with the NAS.
RADIUS can encrypt the entire packet that is sent to the NAS.
RADIUS supports per-command authorization.
