Answer: C

Explanation:

TACACS+ (Terminal Access Controller Access-Control System Plus) is aprotocol that handles authentication, authorization, and accounting (AAA) services.

TACACS+ separates the authentication, authorization, and accounting services enabling you to host each service on a separate server if required.
