See the solution below in Explanation.
Explanation:
* Create PolicySet referencing existing policies:
cat < < 'EOF' | oc apply -f -
apiVersion: policy.open-cluster-management.io/v1beta1
kind: PolicySet
metadata:
name: baseline-dev
namespace: team-dev
spec:
policies:
- policy-ensure-audit-namespace
# Add more policies here as you create them
EOF
* Verify:
oc get policyset -n team-dev
Why this matters:
PolicySets group policies to apply/track as a unit-common governance practice.

See the solution below in Explanation.
Explanation:
* 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).

See the solution below in Explanation.
Explanation:
* In OpenShift Web Console, go to Operators # OperatorHub .
* Search for Advanced Cluster Security .
* Select Red Hat Advanced Cluster Security for Kubernetes (RHACS) .
* Click Install and follow the wizard (namespace/channel per lab).
* After operator installation, create RHACS components (as the hint indicates):
* Install/Deploy Central (the management plane)
* Install/Deploy SecuredCluster (sensor/collector on clusters)
* Confirm operator and pods are running:
* Operators # Installed Operators
* oc get pods -n < rhacs-namespace >
Why this matters:
* RHACS adds container security posture management, vulnerability management, and runtime policy enforcement.

See the solution below in Explanation.
Explanation:
* Ensure clusters have labels like openshiftVersion=4.18 and region=us-west etc.
* Create placement with matchExpressions (include one label, exclude another):
matchExpressions:
- key: openshiftVersion
operator: In
values: ["4.18"]
- key: region
operator: NotIn
values: ["us-west"]
* Validate PlacementDecision.

See the solution below in Explanation.
Explanation:
* Open the RHACS (Central) console (typically via a route created by Central).
* Navigate to: Platform Configuration # System Policies .
* Click Create Policy .
* Set the policy criteria:
* Add a rule/condition such as Image OS = debian:10 (as required by the lab)
* Set enforcement to apply at Build & Deploy stages.
* Build prevents images from being admitted into pipeline/registries depending on integration.
* Deploy prevents or flags deployments that violate policy.
* Save the policy.
* (Optional validation) Trigger a test deployment/image that matches debian:10 to confirm alerts
/enforcement behavior.
Why this matters:
* Enforcing at build+deploy catches risky images earlier and prevents policy violations from reaching runtime.
