Scope map

Lane	What to master	Common weak answer
OpenShift architecture	Understand projects, routes, deployments, image streams, builds, operators, and cluster services.	Treating OpenShift exactly like upstream Kubernetes without platform-specific objects.
Workload management	Create, configure, scale, expose, update, and troubleshoot applications.	Editing resources without verifying route, service, selector, image, and rollout behavior.
Security and access	Use projects, RBAC, SCCs, service accounts, secrets, and image controls.	Granting broad cluster access or privileged containers to bypass a problem.
Operations and troubleshooting	Use oc commands, events, logs, probes, quotas, builds, and deployment status.	Ignoring build logs or events when an app fails to roll out.
Automation and integration	Use templates, operators, pipelines, GitOps or automation patterns where the exam requires them.	Manual one-off changes when repeatable automation is the point.
