PT0-002 Practice Question: Information Gathering and Vulnerability Scanning
This PT0-002 practice question tests your understanding of information gathering and vulnerability scanning. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
In the context of OSINT, which resource would you use to find historical versions of a company's website that may reveal outdated information or hidden directories?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Wayback Machine
The Wayback Machine (archive.org) is the correct resource because it archives historical snapshots of websites, allowing you to view past versions that may contain outdated information, hidden directories, or old configurations no longer present on the live site. This is a core OSINT technique for discovering legacy content or forgotten endpoints.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse OSINT tools focused on current infrastructure (Shodan, Censys) or certificate data (crt.sh) with the only tool that provides historical web content snapshots, the Wayback Machine.
Detailed technical explanation
How to think about this question
The Wayback Machine uses a web crawler to periodically fetch and store copies of web pages, making them accessible via URL-based queries (e.g., web.archive.org/web/*/example.com). This can reveal old robots.txt files, deprecated login pages, or hidden directories that were later removed, which is invaluable for passive reconnaissance. A subtle behavior is that the Wayback Machine may not capture dynamically generated content or pages requiring authentication, but static assets and HTML are typically preserved.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
