GitOps Assessment: Professional (EN)

This assessment checks the level Professional. It combines conceptual questions, diagnostic cases and small design decisions.

Rules

Do not use production secrets.
Justify every answer with GitOps terminology.
Separate source, desired state, actual state, controller and feedback.
Name recovery steps when you mention risky syncs or secret cases.
