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

Nmap service scan with -sV

Nmap service scan sends packets to the target and is an active scanning technique, which may be detected and is not passive.

B

Distractor review

Shodan.io

Shodan is a search engine for internet-connected devices, but it relies on active scanning of IP ranges and is not purely passive for a specific target's web application.

C

Best answer

BuiltWith.com

BuiltWith.com is a passive reconnaissance tool that catalogues technology profiles from public data, allowing identification of frameworks and libraries without interacting with the target.

D

Distractor review

Wappalyzer browser extension

Wappalyzer is a browser extension that analyzes the response from a visited website; it requires visiting the site, which is an active interaction and not purely passive.

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.
