CGOA Gitops Principles Practice Question
A platform team manages 50 Kubernetes clusters using GitOps. They need to ensure that an emergency rollback of an application across all clusters can be executed cleanly and audited effectively. What is the standard GitOps mechanism to achieve this rollback?
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
✓
Revert the bad commit in the Git repository using 'git revert' and merge the change.
In GitOps, all changes—including rollbacks—are executed by interacting with Git. Reverting the Git commit to a previous known-good state causes the GitOps controllers across all 50 clusters to reconcile to that restored desired state, maintaining a complete audit trail.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Execute 'helm rollback' on each individual cluster CLI in parallel.
Why it's wrong here
Manual CLI execution on individual clusters bypasses Git and leads to configuration drift relative to the Git repository.
- ✗
Delete the target namespace in each cluster and let the API server re-download the manifest from cache.
Why it's wrong here
Deleting namespaces causes downtime and does not guarantee correct restoration from Git.
- ✓
Revert the bad commit in the Git repository using 'git revert' and merge the change.
Why this is correct
Reverting the commit in Git updates the target desired state declaratively, allowing automated agents across all clusters to roll back safely while preserving history.
- ✗
Power down the GitOps controller pods so the clusters automatically default to their initial factory settings.
Why it's wrong here
Stopping the GitOps controller leaves the current live state untouched and halts all automated management.
