When configuring an App-of-Apps pattern, which field in the 'Application' manifest controls the order in which child applications are deployed?

You are troubleshooting a multi-cluster Argo CD deployment where the 'staging' cluster is healthy but 'production' cluster is 'OutOfSync' despite having the same manifest source. Why might this happen?

Which mechanism is used in a GitOps workflow to ensure that a 'Canary' deployment successfully rolls back if error rates spike?

Which of the following is a core principle of GitOps?

In a multi-cluster environment, you are managing resources across 50 clusters. Which pattern prevents the 'Control Plane' bottleneck?

What is the purpose of the 'destination' field in an Argo CD Application manifest?

You are using Kustomize 'overlays' for environment promotion. If you need to add a specific label to all resources in production but not in staging, where should you define it?

What is the impact of enabling 'selfHeal' in an Argo CD Application sync policy?

In the context of GitOps, what is 'Configuration Drift'?

During a blue-green deployment, what is the primary role of the traffic manager (e.g., Istio or Nginx Ingress)?

You are designing a multi-cluster deployment with Argo CD. You want to avoid defining 50 individual Application manifests. Which feature should you use?

What does the 'prune' policy in GitOps do?

You want to use Helm for your GitOps deployments. Where should the 'values.yaml' file reside for environment-specific overrides?

In a GitOps promotion pipeline, why is it recommended to tag container images with a unique Git commit SHA instead of 'latest'?

When using Argo CD, how do you handle applications that require resources to be created in a specific order (e.g., CRDs before Operators)?

What is the primary function of an 'ApplicationSet' in Argo CD?

You are using a 'Pull' based GitOps model (e.g., Flux or Argo CD). Why is it considered more secure than a 'Push' based CI/CD model?

What happens if the 'revision' in an Argo CD Application points to a branch that does not exist?

In GitOps, what is the 'Source of Truth'?

Why would you choose to use 'Kustomize' over 'Helm' in a GitOps workflow?

When setting up a multi-cluster GitOps pattern, what is the benefit of using 'Cluster Labels' in ApplicationSets?

When managing multiple environments (dev/stage/prod) in one repository, which folder structure is generally considered best practice?

You are using Argo Rollouts for progressive delivery. You want to execute a 'AnalysisRun' before switching traffic. Where is the 'AnalysisTemplate' defined?

What is the primary role of the 'Reconciler' in a GitOps operator?

You notice your GitOps operator is performing too many API calls to the Kubernetes API server. What is the most likely configuration issue?

What is the main advantage of using a 'Declarative' approach to system management?

If you have a multi-cluster setup and you want to ensure that 'production' clusters only pull images from a hardened internal registry, how can you enforce this in GitOps?
