CompTIA Server+ (SK0-005) — Question 254

A security administrator ran a port scanning tool against a virtual server that is hosting a secure website. A list of open ports was provided as documentation. The management team has requested that non-essential ports be disabled on the firewall. Which of the following ports must remain open?

Answer options

• A. 25
• B. 53
• C. 443
• D. 3389
• E. 8080

Correct answer: C

Explanation

Port 443 is essential for HTTPS traffic, which is required for secure website communication. The other ports listed, such as 25 (SMTP), 53 (DNS), 3389 (RDP), and 8080 (alternative HTTP), are not necessary for the operation of a secure website and can be disabled to enhance security.
