Which access method should a network administrator choose to maintain privacy of user ID and session contents when managing a switch remotely?

• A. Telnet
• B. SSH
• C. HTTP
• D. FTP

Answer: (B)

Using SSH (Secure Shell) for remote management of a switch is the preferred choice due to its strong security features that protect both user ID and session contents. SSH encrypts the communication between the management device and the switch, ensuring that sensitive information, including usernames, passwords, and command outputs, cannot be intercepted by unauthorized parties. This encryption is crucial in preventing potential attacks, such as eavesdropping or session hijacking. In contrast, other methods like Telnet transmit data in plaintext, making it vulnerable to interception. Similarly, HTTP does not provide encryption for data transmitted between a browser and a web server, which can expose user credentials during remote management activities. FTP, although it’s useful for file transfers, also lacks encryption, making it insecure for managing device configurations where privacy is a concern. Therefore, SSH is the optimal choice for securely managing network devices.
