A penetration tester is trying to identify the host's OS version on the subnet 10.7.8.1/25. Which of the following commands will achieve the objective the fastest?

The correct answer is C. nmap -O 10.7.8.1/25. The -O option in Nmap is specifically used for OS detection, which is what the penetration tester needs to identify the operating system version of hosts on the specified subnet. It enables Nmap to perform OS fingerprinting using a combination of TCP/IP stack responses and…

Explanation

The -O option in Nmap is specifically used for OS detection, which is what the penetration tester needs to identify the operating system version of hosts on the specified subnet. It enables Nmap to perform OS fingerprinting using a combination of TCP/IP stack responses and other techniques to determine the OS version. This option is efficient for identifying the OS version and is faster compared to other options, such as -A, because it focuses exclusively on OS detection rather than additional services and
