CompTIA Security+ (SY0-401) — Question 28

Ann, a technician, is attempting to establish a remote terminal session to an end users computer using Kerberos authentication, but she cannot connect to the destination machine. Which of the following default ports should Ann ensure is open?

Answer options

• A. 22
• B. 139
• C. 443
• D. 3389

Correct answer: D

Explanation

The correct answer is D, as port 3389 is used for Remote Desktop Protocol (RDP), which is commonly employed for remote terminal sessions. The other ports listed (22 for SSH, 139 for NetBIOS, and 443 for HTTPS) do not facilitate RDP connections, making them irrelevant in this scenario.
