SSCP Network and Communications Security Practice Question

Which protocol is used to securely transfer files over a network and operates on TCP port 22?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

SSH

SSH (Secure Shell) is used for secure remote login and file transfer, and it operates on TCP port 22. FTP uses ports 20-21, Telnet uses port 23, and SFTP (which runs over SSH) also uses port 22.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Telnet

    Why it's wrong here

    Telnet uses TCP port 23 and is unencrypted.

  • SFTP

    Why it's wrong here

    SFTP does use port 22 by default, but it is a subsystem of SSH; the question asks for the protocol that operates on port 22, and SSH is the core protocol.

  • FTP

    Why it's wrong here

    FTP uses TCP ports 20-21 and is not inherently secure.

  • SSH

    Why this is correct

    SSH uses TCP port 22 and provides secure encrypted communications for file transfer and remote administration.
