A. Device Administration

Explanation:

Terminal access controller access control system (TACACS) is an authentication protocol used for remote communication with any server housed in a UNIX network. TACACS provides an easy method of determining user network access via remote authentication server communication. The TACACS protocol uses port 49 by default.

TACACS uses allow/deny mechanisms with authentication keys that correspond with usernames and passwords. Cisco, which designed and launched the TACACS protocol, is also its owner.
