CompTIA A+ Core 2 (220-1002) — Question 359

A technician needs to connect securely to a Linux-based network appliance in a remote datacenter. Which of the following will the technician MOST likely use?

Answer options

• A. SSH
• B. SFTP
• C. RDP
• D. Telnet

Correct answer: A

Explanation

SSH is the most appropriate choice for secure remote access to a Linux-based system, as it provides encrypted connections. SFTP, while secure, is primarily used for file transfers rather than direct remote access. RDP is typically used for Windows environments, and Telnet lacks security features, making it unsuitable for secure connections.
