Which server allows remote command-line access to a host computer?

Web Server DNS DHCP Telnet

Correct Answer:

Telnet

Explanation:

Remote command-line access to a host is provided by a service that lets you log in remotely and run commands on that host. Telnet is designed for exactly that kind of remote login session over a network, giving you a command-line interface on the remote machine. The other services serve different purposes: a web server delivers web pages to clients, DNS translates domain names to IP addresses, and DHCP assigns IP addresses to devices on a network. So Telnet best fits the idea of remote command-line access. (Note: Telnet sends data in plaintext, so SSH is preferred for secure remote access in practice.)
