LoadRunner interview questions — Hard
106 hard-level LoadRunner questions from our Performance Testing bank, each with the correct answer and an explanation of why it is correct.
This topic slice is available to practise but is not yet part of our indexed set.
What this covers
LoadRunner appears throughout Performance Testing interviews. At hard level, interviewers are typically checking depth under pressure — edge cases, failure modes, performance characteristics, and the trade-offs you accepted. Work through these, then explain your answer out loud; the second part is what interviews actually test.
6 example questions
1. Regarding LoadRunner, which of the following is a false statement?
- A. Think time functions make scripts run as fast as possible.correct
- B. The Controller designs, runs, and monitors load-test scenarios.
- C. Correlation in LoadRunner captures dynamic server values into parameters for replay.
- D. Rendezvous points synchronize Vusers to apply simultaneous load at one step.
Why: The selected statement is false. The other options are accurate statements about LoadRunner.
2. Which statement about LoadRunner is NOT correct?
- A. Parameterization replaces recorded hard-coded values with variable data.
- B. LoadRunner can run all load from the Controller only, never remote generators.correct
- C. Correlation in LoadRunner captures dynamic server values into parameters for replay.
- D. The Controller designs, runs, and monitors load-test scenarios.
Why: The selected statement is false. The other options are accurate statements about LoadRunner.
3. Which of the following statements about LoadRunner is FALSE?
- A. Correlation means hard-coding session IDs into the script.correct
- B. Load generators are machines that host running Vusers to scale load.
- C. The Analysis component processes results after a run to produce graphs and reports.
- D. Lr_think_time simulates user wait time between actions.
Why: The selected statement is false. The other options are accurate statements about LoadRunner.
4. Identify the INCORRECT statement about LoadRunner:

6. During a code review, a reviewer asks: Which LoadRunner component records and scripts user flows?
- A. Controller.
- B. VuGen.correct
- C. Load Generator.
- D. Analysis.
Why: VuGen records actions and produces Vuser scripts.
