CompTIA Network+ (N10-009) — Question 419

A network administrator needs to securely connect to an Ubuntu server for management purposes. Which of the following protocols will most likely address this requirement?

Answer options

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

Correct answer: D

Explanation

The correct answer is D, SSH, as it is specifically designed for secure remote management of servers, including Ubuntu. HTTPS is used for secure web browsing, SFTP is for secure file transfer, and RDP is primarily for remote desktop access, making them less suitable for direct server management.
