Answer - A - Of the protocols mentioned here, Telnet is a network protocol used on the Internet or local area networks to provide a bidirectional interactive communications facility. It provides access to a command-line interface on a remote host via a virtual terminal connection, which consists of an 8-bit byte oriented data connection over TCP.

Key Takeaway: You can enter commands through the Telnet program and they will be executed as if you were entering them directly on the server console. This enables you to control the server and communicate with other servers on the network. To start a Telnet session, you must log into a server by entering a valid username and password. Telnet is a common way to remotely control Web servers.
