Certified Ethical Hacker (CEH v10) — Question 3

If you want only to scan fewer ports than the default scan using Nmap tool, which option would you use?

Answer options

• A. -sP
• B. -P
• C. -r
• D. -F

Correct answer: D

Explanation

The correct answer is D, as the -F option in Nmap specifies a fast scan that scans fewer ports than the default. The other options do not serve the purpose of reducing the number of scanned ports; -sP is for ping scanning, -P is not a valid option for limiting ports, and -r is used for scanning ports in a random order.
