Explanation

There is an inconsistency in this question that's worth flagging before you study it: the question body explicitly states "Answer: Nmap," but the multiple-choice section marks B (Adeona) as correct - and Nmap does not appear among the four choices. These appear to be two different questions that were accidentally merged.

The tool described - free, open-source, network exploration and security auditing, discovers hosts and services, creates a network "map" - is definitively Nmap.

Here's why each listed choice is wrong for the described tool:

• A. SAINT - Security Administrator's Integrated Network Tool; a commercial vulnerability scanner, not primarily a network mapper.
• B. Adeona - An open-source laptop theft-tracking system; nothing to do with network mapping.
• C. Snort - A network intrusion detection/prevention system (IDS/IPS); it monitors traffic, it doesn't map networks.
• D. Nessus - A commercial vulnerability scanner; it probes for weaknesses, not specifically network topology discovery.

Memory tip: Nmap = Network mapper - the name literally describes its function. When you see "maps a network" or "network exploration," think Nmap.

I'd recommend verifying this question against your original source material, as the stated correct answer (B) contradicts both the fill-in answer given and the tool's actual description.
