CV0-004 Troubleshooting Practice Question
A cloud administrator is troubleshooting a failed deployment of a new application version using a continuous integration/continuous deployment (CI/CD) pipeline. The pipeline fails at the 'test' stage. What is the first step the administrator should take?
⚠ Common exam trap
CV0-004 often tests the temptation to jump to remediation (re-run, rollback, increase timeout) before performing the fundamental troubleshooting step of reading logs to identify the actual error.

Correct answer & explanation
✓
Check the test logs for specific errors
When a CI/CD pipeline fails at the test stage, the first diagnostic step is to examine the test logs to identify the specific error — whether it is a failed assertion, a missing dependency, a timeout, or an environment issue. Logs provide the evidence needed to determine root cause before taking any corrective action. Jumping to re-runs or rollbacks without understanding the failure wastes time and may mask a recurring defect.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Re-run the pipeline
Why it's wrong here
Re-running without inspecting logs reproduces the same deterministic test failure and wastes pipeline minutes. Re-running is valid after a confirmed transient infrastructure or flaky-test fault, but here the administrator must first read the test stage output to identify the actual cause.
- ✗
Increase the timeout of the test stage
Why it's wrong here
Extending the timeout assumes the failure is a slow test, yet a failed assertion or compilation error will still fail regardless of duration. Raising timeouts is correct when logs show tests exceeding the limit, but the administrator must first examine the failure output before changing stage configuration.
- ✗
Roll back to the previous version
Why it's wrong here
Rolling back restores the previous release but discards the diagnostic evidence in the failed build and leaves the defect unresolved. Rollback is correct when a bad version has already reached production and must be withdrawn, but this failure occurred at the test stage before deployment, so the cause must be diagnosed first.
- ✓
Check the test logs for specific errors
Why this is correct
The pipeline halts at the test stage, so the failure detail resides in that stage's output. Reviewing the test logs reveals the specific assertion, dependency or environment error before any remediation, avoiding speculative changes to code or pipeline configuration that could mask the actual fault.
