CompTIA Linux+ (XK0-004) — Question 293

Which of the following allows communication over port 3389 to access GUI services?

Answer options

• A. XRDP
• B. VNC
• C. Xfce
• D. KDE
• E. X-forwarding

Correct answer: A

Explanation

The correct answer is XRDP, which specifically allows RDP (Remote Desktop Protocol) connections over port 3389 for GUI access. VNC provides remote desktop capabilities but operates on different ports, while Xfce and KDE are desktop environments and do not facilitate direct communication. X-forwarding is a method for forwarding X11 applications but does not use port 3389.
