PT0-002 Practice Question: Information Gathering and Vulnerability Scanning
This PT0-002 practice question tests your understanding of information gathering and vulnerability scanning. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
During a web application penetration test, the tester wants to discover hidden parameters that the application accepts. Which THREE tools are BEST suited for parameter bruteforcing? (Select THREE.)
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
✓
Arjun
Arjun is specifically designed to discover hidden HTTP parameters by performing parameter bruteforcing using a wordlist. It sends requests with various parameter names and analyzes responses to identify which ones are accepted by the web application, making it a dedicated tool for this task.
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 may confuse general web vulnerability scanners (like Nikto or WPScan) with tools that are purpose-built for parameter bruteforcing, leading them to select tools that lack the specific functionality for discovering hidden parameters.
Detailed technical explanation
How to think about this question
Parameter bruteforcing works by sending HTTP requests with candidate parameter names (e.g., 'id', 'debug', 'token') appended to the query string or POST body, then analyzing response size, status code, or content length for anomalies. Arjun uses a heuristic approach where it compares responses with and without each parameter to detect acceptance, while ffuf can be configured with custom wordlists and filters for precise parameter discovery. In real-world engagements, hidden parameters like 'admin', 'test', or 'backup' can expose debug endpoints or bypass access controls.
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 security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
