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
✓
Automatically reverting manual changes to match the Git repository
Self-healing automatically reverts any manual changes made to the live cluster state back to the desired state defined in Git, ensuring configuration drift is corrected.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Automatically scaling applications based on metrics
Why it's wrong here
Scaling is typically handled by Horizontal Pod Autoscaler or other controllers.
- ✗
Automatically restarting failed pods
Why it's wrong here
Pod restarts are handled by the Kubernetes controller manager, not specifically by ArgoCD self-healing.
- ✓
Automatically reverting manual changes to match the Git repository
Why this is correct
Self-healing ensures the cluster state continuously matches the Git repository, undoing any drift.
- ✗
Automatically updating the Git repository when changes are made in the cluster
Why it's wrong here
That would be bidirectional sync, which is not a standard GitOps practice.
