Areconcilerensures that the actual system matches the desired state declared in Git. External reconcilers run outside the core cluster orchestration process.Fluxis a widely used GitOps external reconciler that continuously syncs cluster state with the repository.

“Flux is an example of a GitOps reconciler that continuously monitors Git repositories and applies changes to the cluster. As an external reconciler, it handles synchronization and reconciliation loops outside the direct application code.”

Thus,A: Fluxis correct.

Kustomize is a GitOps tool for managing Kubernetes configurations declaratively. It uses afolder structure with configuration filesand akustomization.yamlfile that references resources and overlays. This enables customization without modifying the base manifests.

“Kustomize allows customization of Kubernetes manifests by organizing resources in directories and referencing them through file paths in a kustomization file. This directory-based approach supports overlays, reusability, and modular configuration.”

Thus, the correct answer isD.

ACanary Deploymentgradually introduces a new application version to a small subset of users before expanding to the full user base. This pattern allows testing and validation in production while reducing risk.

“Canary deployments progressively roll out changes to a small group of users, monitoring for issues before routing all traffic to the new version. This gradual shift minimizes risk and ensures safer releases.”

Thus, the correct answer isB.

The reconciliation loop is a fundamental GitOps principle. It continuously compares thedesired state(stored in Git) with theactual state(running in the system). When a divergence (drift) is detected, the reconciler automatically corrects the system to match the desired state.

“The reconciliation loop ensures the system is continuously converging toward the declared desired state. Whenever the actual state deviates, the loop reconciles the system to match the desired state.”

Thus, the correct answer isC.
