CompTIA Server+ (SK0-005) — Question 246

An administrator is working on improving the security of a new domain controller. A report indicates several open ports on the server. Which of the following ports should the administrator disable?

Answer options

Correct answer: D

Explanation

Port 3389 is used for Remote Desktop Protocol (RDP), which can be a significant security risk if left open, as it allows remote access to the server. The other ports, while they can also pose risks, are not as commonly exploited for remote access as RDP, making them less of a priority to disable in this context.
