A penetration tester is reviewing a Python script that uses the `requests` library to send HTTP POST requests to a login endpoint. The script attempts to bypass authentication by sending SQL injection payloads in the username field. Which of the following code changes would MOST effectively help the tester identify successful injections by reducing false negatives?

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

Using a `requests.Session` object to maintain cookies across requests

Maintaining cookies is helpful for session handling but does not directly influence the detection of successful injections.

B

Best answer

Parsing the response for specific error messages such as 'SQL syntax' or 'mysql_fetch_array'

This allows the script to confirm that the injection payload was processed by the database, reducing false negatives.

C

Distractor review

Implementing a random delay between requests to avoid rate limiting

Delays help avoid detection by Web Application Firewalls but do not reduce false negatives in detecting vulnerabilities.

D

Distractor review

Adding a function to automatically resend each payload multiple times

Resending payloads may increase coverage but does not improve the accuracy of detecting successful injections.

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: Parsing the response for specific error messages such as 'SQL syntax' or 'mysql_fetch_array' — A false negative occurs when a real vulnerability is not detected. Parsing the response for common SQL error messages (e.g., 'SQL syntax', 'mysql_fetch_array') helps confirm that the injection payload was processed and triggered a database error, thus reducing false negatives. Using a session object maintains state but does not improve detection. Adding delays prevents rate limiting but does not affect accuracy. Sending duplicate payloads may increase coverage but does not directly reduce false negatives.
