AWS CCP (CLF-C02) Crash on the Review Screen: Were Your Answers Submitted?
Exam-day crash during AWS Certified Cloud Practitioner? Here’s what actually happens to your answers, how Pearson VUE handles session recovery, and what to do next.
The review screen is the worst place for a crash. You have answered every CLF-C02 question, you are deciding whether to change a flagged item, and the client disappears. The first question is not “why did this happen?” but “did my answers actually get submitted?”
Short answer: they probably were not submitted
If the [Pearson VUE](https://home.pearsonvue.com/aws) client crashed before you clicked **End exam** and confirmed submission, the session usually has no completed delivery record. That does not mean your responses are gone. It means the exam was not formally ended and your result is likely incomplete.
For test center and OnVUE exams, Pearson VUE can often reopen the same exam session if the clock still has time and the proctor can verify the environment. If the session cannot be recovered, [AWS Training and Certification](https://aws.amazon.com/certification/) and Pearson VUE open an incident case to determine next steps.
How to check whether your answers were submitted
Do not guess. Check these locations:
1. Log in to your AWS Certification Account at [aws.amazon.com/certification](https://aws.amazon.com/certification/).
2. Open Exam History.
3. Look at the CLF-C02 attempt.
Interpretation:
**Scored / Pass / Fail** — the exam was submitted and scored.
**Incomplete / Delivered / No show / In progress** — most likely the crash ended the session before submission.
**No record after 24 hours** — treat it as incomplete and file a case.
Pearson VUE dashboard may show a status called “in progress” or “pending recovery.” If you see that, do not schedule a new attempt.
What to do immediately after the crash
Time matters. The exam clock may still be running even if the client died. For [OnVUE](https://home.pearsonvue.com/onvue):
Do not restart your computer unless instructed.
Reopen the OnVUE browser or secure browser as soon as possible.
Wait for proctor chat to reconnect.
If the proctor cannot rejoin, note the error code and timestamp.
In a test center:
Stay in your seat.
Raise your hand immediately.
Ask the proctor to file an incident report before you leave.
Get a case number or incident reference.
Then open a support case with [AWS Training and Certification](https://support.aws.amazon.com/#/contacts/aws-training-certification) within 24–48 hours. Use the Pearson VUE case number if provided. In your message include:
Exam: AWS Certified Cloud Practitioner CLF-C02
Test method: OnVUE or test center
Timestamp and timezone
Error message or crash behavior
Machine type and OS if online
Why the review screen is special
Most exams save responses locally as you move between questions, but that local cache is meant to prevent single-question loss, not to replace a formal submission. The final review screen is a holding state. The exam is completed only after you click **End exam** and the client communicates that final event.
If the client crashes before that final event, the server may see a disconnected session rather than a submitted exam. Some test environments checkpoint answers to the server at intervals, but you should not rely on that for a result.
Will you have to pay to retake?
If AWS Training and Certification or Pearson VUE confirms a technical failure, you will typically be offered a retake or rebook without additional cost. This is handled case by case. If you self-schedule a new exam before the incident is resolved, you might pay again or create a duplicate attempt that complicates the case.
Does a crash ever still produce a result?
Yes. Sometimes the client crashes after the final submission request was sent but before the UI updates. In that case the attempt may be scored. The dashboard check is the source of truth. A crash on the review screen before clicking submit is much less likely to produce a result, but not impossible.
What to do while waiting
Do not schedule a retake.
Do not assume you failed.
Keep your case number.
Monitor your AWS Certification Account and email.
A note from Sapior
At Sapior, we think a lot about this exact failure shape: captured state, session durability, and what happens when a browser dies before the final commit. For online proctoring and any browser-based assessment, the safest design is explicit submission with clear state. The same pattern applies in developer tools: persist locally, send idempotent events, and make terminal state visible to the user.
