CGOA Gitops Patterns Practice Question
You are using the App-of-Apps pattern in Argo CD to manage hundreds of microservices. You notice that the parent application is stuck in a 'Syncing' state indefinitely. What is the most likely cause?
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
✓
The child application's manifests include the parent application as a dependency.
In an App-of-Apps pattern, if the parent application has 'self-heal' or 'prune' enabled, it may conflict with child applications if the sync policy is misconfigured, often caused by circular dependencies or the parent attempting to manage its own child resources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The parent application is not using a Helm chart source.
Why it's wrong here
App-of-Apps pattern functions perfectly with Kustomize or standard YAML.
- ✗
The Argo CD API server has exceeded its connection limit.
Why it's wrong here
This would cause a 'Connection Refused' or '503' error, not a stuck sync state.
- ✓
The child application's manifests include the parent application as a dependency.
Why this is correct
A circular dependency occurs when a child application defines the parent as a source, preventing the sync process from completing.
- ✗
The parent application is missing the sync-policy configuration.
Why it's wrong here
Missing sync policy results in no automatic sync, not a stuck sync.
