CompTIA Network+ (N10-008) — Question 127

Which of the following protocols would allow a secure connection to a Linux-based system?

Answer options

• A. SMB
• B. FTP
• C. RDP
• D. SSH

Correct answer: D

Explanation

SSH (Secure Shell) is designed to provide a secure channel over an unsecured network, making it the appropriate choice for a secure connection to a Linux system. In contrast, SMB (Server Message Block) and FTP (File Transfer Protocol) do not offer encryption, and RDP (Remote Desktop Protocol) is primarily used for graphical remote desktop access rather than secure command-line access.
