CompTIA A+ Core 2 (220-1102) — Question 620

A help desk team lead contacts a systems administrator because the technicians are unable to log in to a Linux server that is used to access tools. When the administrator tries to use remote desktop to log in to the server, the administrator sees the GUI is crashing. Which of the following methods can the administrator use to troubleshoot the server effectively?

Answer options

• A. SFTP
• B. SSH
• C. VNC
• D. MSRA

Correct answer: B

Explanation

SSH is the most effective method for troubleshooting a Linux server because it provides a secure command-line interface that does not rely on a graphical user interface, which is failing in this case. SFTP is primarily used for file transfers, VNC is dependent on GUI access which is not functional, and MSRA is a Windows-specific remote assistance tool that is not applicable in this Linux scenario.
