Gitops Patterns

In a multi-cluster GitOps architecture using Argo CD, how do you manage credentials for a remote cluster that is not the cluster where Argo CD resides?

In a blue-green progressive delivery deployment using Flagger, you notice that the 'primary' service is not receiving traffic even after the analysis successfully completes. What is the most likely cause?

You are deploying applications across multiple clusters using Argo CD. You want to implement a hub-and-spoke model where the central management cluster controls all edge clusters. Which THREE of the following are necessary to correctly configure this pattern?

When promoting an application from staging to production using the 'GitOps directory' pattern, what is the most robust way to ensure environment-specific configurations are applied correctly?

You are managing a large-scale deployment using the App-of-Apps pattern in Argo CD. Which resource type do you primarily use as the parent application to reference child application manifests?

You are implementing progressive delivery with Flagger. You notice that the canary analysis is failing despite the new version being stable. What is the most common reason for this?

What is the primary benefit of using a 'Git Branch' promotion pattern over a 'Directory-based' promotion pattern?

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?

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?

Which Argo CD feature allows you to manage multiple applications with shared configuration?

Which TWO of the following are essential when using Helm in a GitOps workflow? (Select two)

Which TWO of the following are common benefits of using a 'GitOps Operator'? (Select two)

Which THREE of the following are essential security practices for GitOps? (Select three)

Your organization uses a 'Git-branch-per-environment' strategy. You notice that hotfixes applied to the 'production' branch are being overwritten by automatic merges from the 'staging' branch. Which GitOps promotion pattern should you adopt to prevent this drift?

When deploying across multiple clusters using Argo CD, you need to ensure that specific secrets are only available to clusters located in the 'us-east' region. Which resource should you use to enforce this segregation?

You are performing a Canary deployment using Argo Rollouts. You notice that the analysis template is failing even though the metrics are within range. What is the most common cause of this in a GitOps workflow?

In a multi-cluster GitOps environment, you are using the ApplicationSet controller with a 'Cluster Generator'. You need to add a new cluster dynamically without modifying the ApplicationSet manifest. How should you achieve this?

You have a GitOps pipeline where you want to promote a change from Staging to Production. Using Argo CD, what is the recommended way to perform this promotion?

Which THREE of the following are benefits of using the App-of-Apps pattern? (Select THREE)

You are implementing a GitOps promotion workflow where each environment (dev, staging, prod) has its own Kubernetes namespace in a single cluster. Your team wants to keep the base manifests identical and only vary replicas, resource limits, and image tags per environment. Which pattern should you use to achieve this with minimal duplication?

You are using Argo CD to manage a production application. A developer accidentally commits a change that sets the replica count to zero, and the change is merged to the main branch. You want to prevent this from happening again without blocking all changes to the repository. Which GitOps pattern should you implement?

You are managing a GitOps repository that contains both application manifests and cluster-wide configurations. You want to ensure that changes to cluster-wide configurations are applied before application workloads during a sync. Which Argo CD feature should you use?

You are using Flux CD to manage a multi-tenant cluster. Each tenant has its own Git repository and namespace. You want to ensure that a tenant's Kustomization can only deploy resources into its own namespace and cannot modify cluster-scoped resources. Which Flux feature should you configure?
