Which option selects a lighter version scanning mode via an alias for a specific intensity?

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

Answer: (A)

Controlling how deeply Nmap probes for software versions is about balancing speed and detail; there are quick ways to get a rough idea by using a light version detection mode. The -sV option turns on version detection, and pairing it with the alias --version-light activates a lighter set of probes. This lets Nmap gather version information more quickly and with less network impact, which is exactly what a lighter scanning mode aims to achieve. The other options don’t fit this goal: one would require a numeric intensity value after --version-intensity, which isn’t shown here; another enables decoy scans, and the last enables a broad, aggressive scan including many features, not a lighter version check.
