Between SSH and Telnet, which provides encrypted remote access suitable for management?

• A. Telnet
• B. Secure Shell
• C. HTTP
• D. FTP

Answer: (D)

Encrypted remote management relies on a secure channel that protects both credentials and commands as they travel across the network. Secure Shell provides exactly that by encrypting the entire session, so login details and subsequent actions cannot be easily intercepted or tampered with. Telnet, in contrast, transmits data in plaintext, exposing passwords and commands to anyone who can sniff the network. HTTP is for web traffic, not interactive remote management, and FTP is for file transfer rather than secure remote command access (even though secure variants exist, they serve different purposes). So for encrypted remote access suitable for management, Secure Shell is the correct choice.
