NEW QUESTION # 28
Create a policy that enforces a specific Operator to be installed on all dev clusters
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Use a policy template approach (OperatorGroup + Subscription + desired namespace) in a ConfigurationPolicy.
* Bind it to a Placement targeting dev clusters.
* Verify operator subscription exists on managed clusters and CSV reaches Succeeded.
Why this matters:
Automating consistent operator installation at scale is a realistic governance task; community policy collections exist demonstrating this model.
NEW QUESTION # 29
Create Overlay Directory (Kustomize)
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* 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.).
NEW QUESTION # 30
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.
NEW QUESTION # 31
Create a namespace-scoped application deployment model using ClusterSetBinding + Placement
Answer:
Explanation:
See the solution below in Explanation.
* Bind the ClusterSet into the application namespace using ManagedClusterSetBinding.
* Create Placement in that namespace selecting the desired clusters.
* Deploy application resources tied to that placement (Subscription or GitOps pattern). Why this matters: This is the standard multi-tenant ACM pattern for teams.
NEW QUESTION # 32
Set TimeWindow for App (Web Console)
Task information: Add timeWindow to Subscription spec (active window Friday 09:00-17:00)
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* In ACM console go to Applications .
* Select the application you deployed.
* Open the Editor view (YAML editor) for the Subscription object.
* Under spec, add a timeWindow section similar to what the lab requests:
* windowtype: active
* day: Friday
* hours: 09:00-17:00
* Save/apply the changes.
* Verify the Subscription YAML now contains the time window and observe that deployment actions respect the scheduling window.
Why this matters:
* Time windows let you control when changes roll out (useful for change-management, business hours, and maintenance windows).
NEW QUESTION # 33
Configure a maintenance window for deployments (time window concept) and validate drift
Answer:
Explanation:
See the solution below in Explanation.
* Edit the subscription/app definition to include a time window (active or blocked window).
* Attempt a change outside the window and observe behavior (no rollout until window).
* Confirm rollout during window.
NEW QUESTION # 34
Create a Governance Policy to ensure a namespace exists on selected clusters
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
Policies in ACM require:
* a Policy resource
* a Placement (which clusters to target)
* a PlacementBinding (bind policy # placement)
* Create the Policy (in team-dev) enforcing a namespace audit-logs:
cat < < 'EOF' | oc apply -f -
apiVersion: policy.open-cluster-management.io/v1
kind: Policy
metadata:
name: policy-ensure-audit-namespace
namespace: team-dev
spec:
remediationAction: enforce
disabled: false
policy-templates:
- objectDefinition:
apiVersion: policy.open-cluster-management.io/v1
kind: ConfigurationPolicy
metadata:
name: ensure-audit-namespace
spec:
remediationAction: enforce
severity: low
object-templates:
- complianceType: musthave
objectDefinition:
apiVersion: v1
kind: Namespace
metadata:
name: audit-logs
EOF
* Create PlacementBinding to bind it to dev-clusters placement:
cat < < 'EOF' | oc apply -f -
apiVersion: policy.open-cluster-management.io/v1
kind: PlacementBinding
metadata:
name: bind-policy-ensure-audit-namespace
namespace: team-dev
placementRef:
apiGroup: cluster.open-cluster-management.io
kind: Placement
name: dev-clusters
subjects:
- apiGroup: policy.open-cluster-management.io
kind: Policy
name: policy-ensure-audit-namespace
EOF
* Verify compliance:
oc get policy -n team-dev
oc describe policy policy-ensure-audit-namespace -n team-dev
Why this matters:
This is the core "ACM governance" exam pattern: define desired state and enforce across clusters.
NEW QUESTION # 35
Install RHACS secured cluster services on managed clusters using a governance policy approach
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Use a policy-based deployment model that installs RHACS components consistently across clusters (operator + secured cluster).
* Bind policy to placement selecting target clusters.
* Validate RHACS Sensor/Collector present in expected namespace on managed clusters.
Policy collections exist demonstrating RHACS installation patterns via policy framework.
NEW QUESTION # 36
Grant a team group "edit" access to the namespace that has a ClusterSetBinding
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Create a group (example) and add users:
oc adm groups new dev-team
oc adm groups add-users dev-team user1 user2
* Grant namespace access:
oc adm policy add-role-to-group edit dev-team -n team-dev
* Validate with a user token/login (or check rolebindings):
oc get rolebinding -n team-dev | grep dev-team
Why this matters:
ACM access patterns commonly combine namespace RBAC + ClusterSetBinding to scope what teams can manage.
NEW QUESTION # 37
Create Kustomization File
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Create an empty kustomization file:
* touch overlays/production/kustomization.yaml
* Validate it exists:
* ls -l overlays/production
Why this matters:
* kustomization.yaml is the entrypoint file Kustomize uses to build overlays.
NEW QUESTION # 38
Install RHACM Operator (Web Console)
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Log in to the OpenShift Web Console as a cluster-admin user.
* Go to Operators # OperatorHub .
* OperatorHub is the catalog of available operators.
* In the search box, type: Advanced Cluster Management .
* Click Advanced Cluster Management for Kubernetes (Red Hat ACM).
* Click Install .
* In the install wizard:
* Update channel : choose the recommended/stable channel for your lab.
* Installation mode : typically "All namespaces on the cluster" (default).
* Installed Namespace : select or create open-cluster-management .
* Click Install and wait for the operator to show Succeeded in:
* Operators # Installed Operators .
Why these steps matter:
* Installing the ACM operator creates the CRDs/controllers required to run the Hub components (MultiClusterHub) that manage/import other clusters.
NEW QUESTION # 39
Rotate/renew managed cluster access (agent cert / CSR workflow) and restore connectivity
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* On hub: inspect managed cluster conditions for certificate issues.
* Check pending CSRs (if applicable in your lab):
oc get csr
* Approve relevant CSRs and verify managed cluster returns Ready. Why this matters: Certificate- driven trust is core to "secure clusters" operations in ACM.
NEW QUESTION # 40
Create a "deny" baseline policy: ensure a prohibited Namespace does NOT exist
Answer:
Explanation:
See the solution below in Explanation.
* Create a ConfigurationPolicy using mustnothave complianceType (common policy pattern).
* Bind to placement.
* Confirm noncompliance if the namespace exists; enforce removes it if remediation is enforce.
NEW QUESTION # 41
Install RHACS Operator (Web Console)
Answer:
Explanation:
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.
NEW QUESTION # 42
Troubleshoot a policy that shows "Pending" (no placement decisions)
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Confirm the policy exists in the namespace:
oc get policy -n team-dev
* Confirm Placement exists and selects clusters:
oc get placement -n team-dev
oc get placementdecision -n team-dev
* Confirm PlacementBinding points to correct placement + policy:
oc get placementbinding -n team-dev -o yaml
* Fix common mistakes:
* wrong namespace
* placement name mismatch
* missing ClusterSetBinding in the namespace Why this matters: Policy framework requires placement + binding; missing/incorrect targeting is the #1 real-world issue.
NEW QUESTION # 43
Configure Observability (MultiClusterObservability) with object storage credentials
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Create the object storage secret (you'll be given endpoint/access keys in an exam):
oc -n open-cluster-management-observability create secret generic thanos-object-storage \
--from-file=thanos.yaml=/path/to/thanos.yaml
* Create or edit MultiClusterObservability CR to enable observability (storage class, retention, etc.).
* Verify observability pods in the observability namespace and check dashboards/metrics. Why this matters: Monitoring health/performance with ACM observability is a common learning objective in ACM training.
NEW QUESTION # 44
Create a policy to enforce "etcd encryption enabled" and verify compliance status
Answer:
Explanation:
See the solution below in Explanation.
* In ACM console: Governance # Create policy # ETCD Encryption template and set to enforce .
* Target clusters via Placement.
* Confirm policy status: Compliant / NonCompliant per cluster.
