Telnet is used for which of the following remote interactions?

• A. It is a file transfer protocol
• B. It is used for routing web pages
• C. It provides secure encrypted communication
• D. It is an application-layer protocol used for remote command-line interface

Answer: (D)

Telnet is an application-layer protocol that provides remote access to a system via a command-line interface. It establishes a session with the target device so you can log in and execute commands as if you were sitting at the machine. It does not encrypt data, so it’s not used for secure communications (SSH is the secure alternative). Telnet isn’t a file transfer protocol and it isn’t used to route web pages. The essential idea is remote, interactive command-line access to manage and control a device.
