Computer Hacking Forensic Investigator (CHFI v10) — Question 105

What is the following command trying to accomplish?
C:> nmap `"sU `"p445 192.168.0.0/24

Answer options

• A. Verify that UDP port 445 is open for the 192.168.0.0 network
• B. Verify that TCP port 445 is open for the 192.168.0.0 network
• C. Verify that NETBIOS is running for the 192.168.0.0 network
• D. Verify that UDP port 445 is closed for the 192.168.0.0 network

Correct answer: A

Explanation

The correct answer is A because the command uses 'sU', indicating a scan for UDP ports, specifically port 445, on the specified subnet. Option B is incorrect as it refers to TCP rather than UDP. Option C is wrong because the command does not check for NETBIOS, and option D incorrectly suggests that the command is verifying if the port is closed.
