CompTIA A+ Core 2 (220-1002) — Question 270

A vendor requires remote access to a specific server to maintain proprietary software system. Security policy restricts the use of port 3389 to employees but does allow command-line access to non-employees. Which of the following would MOST likely need to be enabled?

Answer options

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

Correct answer: A

Explanation

The correct answer is A, RDP, as it specifically uses port 3389 for remote desktop access, which is needed by the vendor. The other options, Telnet and FTP, are less secure and not suitable for the context of remote access to a server, while SSH, although secure, is not the primary method required in this scenario.
