To scan a single specified port, which Nmap option would you use?

• A. -p80
• B. -F
• C. -p-
• D. -sV

Answer: (A)

Specifying a single port in Nmap is done with the -p option, followed by the port number you want to scan. By using -p80, you tell Nmap to scan only port 80 on the target. This is handy when you want to verify that a specific service is open on that port. Other options have different purposes: -F performs a fast scan of the top 100 ports, -p- scans all 65535 ports, and -sV performs service version detection rather than changing which ports are scanned.
