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

The network administrator should choose SSH (Secure Shell) to keep the user ID, password, and session contents private when establishing remote CLI connectivity with a switch. SSH provides a secure channel over an unsecured network by using encryption, which ensures confidentiality and integrity of data.

The other methods listed have the following characteristics:

• AUX (Auxiliary port): This is used for remote management similar to the console port but usually over a modem. It does not inherently provide encryption for security.
• Telnet: This is an older protocol that provides no encryption, making it insecure for transmitting sensitive information because the session contents, including user ID and password, can be intercepted.
• Console: The console port is for direct physical connection to the device and does not provide encryption because it’s designed for a direct serial connection rather than remote access.
