You must classify workflow practices as GitOps-recommended or anti-patterns and read controller status correctly. The key point: Git holds the single source of truth for desired state, and a controller continuously reconciles the cluster toward it, flagging drift as OutOfSync.

Domain overview
This domain covers the vocabulary and mental model behind GitOps: desired state, reconciliation, drift, sync status, and the boundary between declarative config in Git and the controller that applies it. Questions are scenario-style, asking you to classify practices as recommended or anti-patterns and to interpret controller status output.
Exam objectives
Defining a GitOps controller's job: continuously reconcile cluster state with the declared desired state in Git.
Interpreting Argo CD sync statuses such as Synced, OutOfSync, and the health field shown alongside them.
Recognizing anti-patterns like manual kubectl edits, storing secrets in plain Git, and using CI push instead of pull.
Distinguishing declarative desired state in Git from imperative commands and from runtime observed state.
Treating OutOfSync as an error rather than a signal that live state differs from Git and reconciliation is pending or blocked.
Confusing CI-driven push deployments with GitOps pull-based reconciliation, then picking push as a recommended practice.
Assuming the GitOps controller writes changes back to Git; it applies desired state, it does not author commits.

65A platform team manages a Kubernetes cluster with Flux. They want to ensure that if the cluster's live state diverges from the Git repository, the system automatically corrects it without human intervention. Which GitOps concept does this describe?
66A platform team runs Argo CD against a Git repository that holds Helm charts for a production cluster. During an incident, an SRE patches a Deployment directly with `kubectl set image` to roll back a bad release. Two minutes later the Deployment is back on the bad image.
