You are working as a technician at Certkiller .com. Lately you have been busy with configuring a
firewall for the research department. Which of the following protocols would you allow in order to
access a remote host with a local host through a terminal window?

A.
HTML

B.
HTTP

C.
IMAP

D.
Telnet

Explanation:
Telnet is a terminal emulation program for TCP/IP networks such as the Internet. The Telnet
program runs on your computer and connects your PC to a server on the network. You can then
enter commands through the Telnet program and they will be executed as if you were entering
them directly on the server console.
