Free Practice Questions for RedHat EX432 Exam

Grant the role:

oc adm policy add-cluster-role-to-user open-cluster-management:managedclusterset:admin:production user-a

Confirm the binding:

oc get clusterrolebinding | grep -i production | grep -i user-a

Why this matters:

ACM provides ClusterSet-scoped roles. This grants admin permissions limited to the production ClusterSet (instead of full cluster-admin).

Create overlay structure:

mkdir -p overlays/production

Confirm:

ls -R overlays

Why this matters:

Kustomize overlays let you maintain base manifests and environment-specific patches (production vs dev, etc.).

Apply the subscription/application manifest:

oc apply -f application-subscription.yaml

Confirm resources were created:

oc get applications.app.k8s.io -A

oc get subscriptions.apps.open-cluster-management.io -A

oc describe application.app.k8s.io my-app -n < namespace >

Watch placement/propagation (varies by model used in the lab):

oc get placement -A

oc get placementrule -A

Why this matters:

ACM “application” deployment commonly uses Subscription/Placement (legacy model) or newer Placement resources, enabling multi-cluster rollout from Git sources.
