- A
Add a delay with 'sleep 1' between requests to avoid rate limiting.
Why wrong: Rate limiting avoidance is useful, but it does not help in interpreting the output to find successful logins.
- B
Pipe the output to 'grep -v 200' to exclude any responses that are not 200 OK.
Why wrong: This would exclude 200 responses but might also miss redirects (302) which are common indicators of success.
- C
Add a conditional statement that checks if the HTTP status code is 302 (redirect) or 200, and if so, prints the successful credentials.
This directly identifies successful login attempts by checking for common success status codes and outputting the credentials.
- D
Use 'curl -v' to see the full response headers.
Why wrong: Verbose output shows more information but still requires manual inspection; it does not automatically identify success.
Quick Answer
The answer is to add a conditional statement that checks for HTTP status codes 302 or 200 and prints the successful credentials. This improvement directly addresses the core problem of the password spraying script output: a raw, continuous stream of HTTP codes that is impossible to interpret at scale. By wrapping the curl command in an if-then condition, the tester transforms meaningless numbers into actionable intelligence, immediately isolating the valid user/password pair. On the CompTIA PenTest+ PT0-002 exam, this scenario tests your understanding of output parsing and conditional logic in Bash automation, a common trap being that testers focus on speeding up the spray rather than filtering results. The key insight is that a 302 redirect often indicates a successful authentication in web applications, while a 200 can also signal a valid session. Remember the memory tip: “Catch the redirect, print the creds” — if you see a 302 or 200, you’ve found your entry point.
PT0-002 Tools and Code Analysis Practice Question
This PT0-002 practice question tests your understanding of tools and code analysis. 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.
A penetration tester is analyzing a Bash script that automates a password spraying attack. The script contains the following loop: 'for user in $(cat users.txt); do for pass in $(cat passwords.txt); do curl -s -o /dev/null -w "%{http_code}" --data "user=$user&pass=$pass" http://target/login; done; done'. The script runs but the output is a continuous stream of HTTP status codes that are hard to interpret. Which improvement would most effectively help the tester identify a successful login?
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
Add a conditional statement that checks if the HTTP status code is 302 (redirect) or 200, and if so, prints the successful credentials.
Option C is correct because the script currently outputs a raw stream of HTTP status codes with no context. Adding a conditional to check for 302 (redirect, often indicating a successful login) or 200 (OK) and printing the corresponding credentials allows the tester to immediately identify which user/password pair succeeded, turning an unreadable output into actionable intelligence.
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 assume filtering out 200 codes (Option B) will reveal successes, but they overlook that many real-world login flows use a 302 redirect for success, making 'grep -v 200' ineffective or misleading.

Detailed technical explanation
How to think about this question
In password spraying attacks, web applications often return HTTP 302 Found after successful authentication to redirect the user to a dashboard, while 200 OK might indicate the login page itself or a successful AJAX login. The curl command with '-w "%{http_code}"' outputs only the status code, so without context the tester cannot correlate codes to credentials. A conditional that prints the user and pass when a success code is detected transforms the output into a targeted credential discovery tool.
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.
