Explanation:
Secure Shell (SSH) is a cryptographic network protocol for securing data communication. It establishes a
secure channel over an insecure network in a client-server architecture, connecting an SSH client
application with an SSH server. Common applications include remote command-line login, remote
command execution, but any network service can be secured with SSH. SSH uses port 22.
Incorrect Answers:
A: Port 23 is used by the Telnet protocol, not by SSH.
B: Port 32 is an unassigned port.
C: Port 12 is an unassigned port.
