A penetration tester wants to identify live hosts on a large internal network. Which Nmap option would be the FASTEST for initial host discovery?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

-sV (Version detection)

Version detection probes open ports to determine service versions, which is slower than a simple host discovery.

B

Distractor review

-sS (SYN stealth scan)

SYN scan is a port scanning technique; it scans ports on each host, which is more time-consuming than a ping sweep.

C

Best answer

-sn (Ping sweep)

The -sn option uses minimal probes to determine host availability and is the fastest method for host discovery.

D

Distractor review

-A (Aggressive scan)

Aggressive scan enables OS detection, version detection, script scanning, and traceroute, making it much slower.

Common exam trap

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Technical deep dive

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

FAQ

Questions learners often ask

What does this PT0-002 question test?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: -sn (Ping sweep) — The -sn option performs a ping sweep (ICMP echo, TCP ACK on port 80, etc.) and only reports which hosts are up, without scanning ports. It is the quickest method for mapping live hosts on a network.

What should I do if I get this PT0-002 question wrong?
