Answer options

• A. nmap -vv sUV -p 53, 123-159 10.10.1.20/24 -oA udpscan
• B. nmap -vv sUV -p 53,123,161-162 10.10.1.20/24 -oA udpscan
• C. nmap -vv sUV -p 53,137-139,161-162 10.10.1.20/24 -oA udpscan
• D. nmap -vv sUV -p 53, 122-123, 160-161 10.10.1.20/24 -oA udpscan

Correct answer: C

Explanation

The correct answer is C because it includes the ports for DNS (53), NetBIOS (137-139), and SNMP (161-162). Option A incorrectly includes ports 123-159, which do not correspond to the requested services. Option B is missing the NetBIOS ports, and option D includes incorrect port ranges that do not match the specified services.
