Which option speeds up version scanning by using a lighter mode?

• A. -p80
• B. -sV --version-intensity
• C. -F
• D. -sV --version-light

Answer: (D)

Version detection can be sped up by using a lighter set of probes, which reduces the work Nmap has to do while fingerprinting services. The dedicated lighter mode for version scanning is enabled by adding the lighter flag to the version-detection option. This tells Nmap to use a smaller, faster probe set and simpler checks, delivering results more quickly but with a bit less detail and potential fingerprint accuracy. That makes it the best fit when you want a faster version scan. Other options don’t implement the light fingerprinting approach. Targeting a single port changes what is scanned rather than how deeply version probes are performed. Using a fast mode that only limits the number of ports scanned speeds up the overall run but doesn’t specifically lighten the version-detection probes. Adjusting version-intensity changes how aggressively probes are sent, but it isn’t the dedicated lighter mode option.
