A network administrator needs to keep the user ID, password, and session contents private when establishing remote CLI connectivity with a router to manage it. Which of the following access methods should be chosen?

SSH (Secure Shell) encrypts the entire session including authentication (user ID and password) and all subsequent command traffic. Telnet transmits everything in cleartext, making it vulnerable to eavesdropping. Console and AUX ports provide local physical access but don't provide encryption. For keeping session contents and credentials private over a remote connection, SSH is the only secure option among these choices.
