Certified Ethical Hacker (CEH v10) — Question 128

>NMAP ""sn 192.168.11.200-215 The NMAP command above performs which of the following?

Answer options

• A. A port scan
• B. A ping scan
• C. An operating system detect
• D. A trace sweep

Correct answer: B

Explanation

The command uses the '-sn' option, which initiates a ping scan to identify live hosts without performing a port scan. The other options do not accurately describe the function of this command: a port scan checks for open ports, OS detection identifies the operating system, and a trace sweep maps the network path to a target.
