Which of the following ports should be used by a system administrator to securely manage a remote server?
Secure Shell (SSH) is a more secure replacement for Telnet, rlogon, rsh, and rcp. SSH can be called a remote
access or remote terminal solution. SSH offers a means by which a command-line, text-only interface

use of TCP port 22.
