                            Switch a policy from enforce # inform (report-only) and validate behavior

                            Answer:

                            Explanation:
                            See the solution below in Explanation.
                            Explanation:
                            * Patch remediation to inform:
                            oc patch policy policy-ensure-audit-namespace -n team-dev --type=merge -p '{"spec":{"remediationAction":" inform"}}'
                            * Verify:
                            oc get policy policy-ensure-audit-namespace -n team-dev -o yaml | grep remediationAction -n
                            * Observe compliance changes (policy will report but not auto-fix).


                            NEW QUESTION # 42
                            Deploy an application using Subscription + PlacementRule (legacy model)

                            Answer:

                            Explanation:
                            See the solution below in Explanation.
                            Explanation:
                            * Create a Channel (Git) and Subscription referencing it (example pattern).
                            * In exams, you're usually given a repo URL and target namespace.
                            * Ensure there is a placement rule/placement selecting clusters.
                            * Apply manifests:
                            oc apply -f channel.yaml
                            oc apply -f subscription.yaml
                            * Verify resources:
                            oc get channels.apps.open-cluster-management.io -A
                            oc get subscriptions.apps.open-cluster-management.io -A
                            oc get application.app.k8s.io -A
                            Why this matters:
                            Multi-cluster application lifecycle is part of ACM operations, and EX480 explicitly covers managing multi- cluster environments with ACM.


                            NEW QUESTION # 43
                            Create ETCD Encryption Policy (Web Console)

                            Answer:

                            Explanation:
                            See the solution below in Explanation.
                            Explanation:
                            * Open the ACM console on the hub.
                            * Navigate to Governance # Policies .
                            * Click Create policy .
                            * Set Name : policy-etcd.
                            * Choose the policy template/type ETCD Encryption .
                            * Set Remediation action to enforce .
                            * inform = report only
                            * enforce = attempt to automatically remediate to desired state
                            * Select clusters/ClusterSets to apply (depends on the wizard).
                            * Click Submit .
                            * Verify compliance once applied:
                            * In console, check policy status: Compliant/NonCompliant
                            * Or via CLI:
                            * oc get policy -A
                            * oc describe policy policy-etcd -n < policy-namespace >
                            Why this matters:
                            * Governance policies are a core ACM feature for enforcing security baselines across multiple clusters.


                            NEW QUESTION # 44
                            Create MultiClusterHub (CLI Alternative)
                            Task information: Apply the MultiClusterHub custom resource if not using Web Console.

                            Answer:

                            Explanation:
                            See the solution below in Explanation.
                            Explanation:
                            * Ensure you are logged into the hub cluster:
                            * oc whoami
                            * oc project open-cluster-management
                            * Create/apply the MultiClusterHub CR:
                            * oc apply -f multiclusterhub.yaml
                            * Verify it was created:
                            * oc get multiclusterhub -A
                            * oc describe multiclusterhub -n open-cluster-management
                            * Watch pods come up (typical namespaces include open-cluster-management, open-cluster- management-hub, etc. depending on ACM version/config):
                            * oc get pods -n open-cluster-management -w
                            Why these steps matter:
                            * The MultiClusterHub CR is the "hub installation" object. The operator reconciles it and installs
                            /maintains hub services.


                            NEW QUESTION # 45
                            Deploy GitOps Application (Subscription YAML)

                            Answer:

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