Certified Ethical Hacker (CEH v10) — Question 46

You have successfully comprised a server having an IP address of 10.10.0.5. You would like to enumerate all machines in the same network quickly.
What is the best Nmap command you will use?

Answer options

• A. nmap -T4 -q 10.10.0.0/24
• B. nmap -T4 -F 10.10.0.0/24
• C. nmap -T4 -r 10.10.1.0/24
• D. nmap -T4 -O 10.10.0.0/24

Correct answer: B

Explanation

The correct answer is B, as using the '-F' option with Nmap performs a fast scan, which is ideal for quickly enumerating machines in the same subnet. Option A is incorrect because '-q' is used for quiet mode, which does not help with enumeration. Option C targets a different subnet and is irrelevant, while option D is focused on OS detection, which is not necessary for a quick enumeration.
