Explanation

This answer key contains a clear error. The stated answer B runs nmap against 192.168.100.1, which is the domain controller - not the imaging web server. The question explicitly asks about confirming open ports on the web server (192.168.101.24). The correct answer is D: 'nmap -p- 192.168.101.24'. The -p- flag tells nmap to scan all 65,535 TCP ports on the target. This is the only way to definitively confirm that no unexpected ports (such as port 80 for unencrypted HTTP) are open. Option A only checks ports 80 and 443, which would miss any other open ports. Option C scans the client machine, which is irrelevant. Option D, scanning all ports on the actual imaging server, is the correct and thorough approach to confirm the server's exposure.
