When managing a switch with SSH, which statement is true?

• A. It uses Telnet.
• B. It provides remote access with data encryption during the session.
• C. It is only for local console access.
• D. It uses HTTP.

Answer: (B)

Secure remote administration of a switch relies on encrypting the entire session so credentials and commands aren’t exposed. SSH provides exactly that: remote access with data encryption during the session, protecting both authentication and ongoing command traffic as you manage the device from a distance. The alternative of Telnet is insecure because it sends login information and commands in plaintext, making eavesdropping easy. HTTP is a web protocol, not a secure command-line management channel for a switch (though HTTPS can secure a web GUI, it serves a different interface). SSH typically operates over TCP port 22, enabling secure remote CLI administration rather than just local console access.
