NEW QUESTION # 32
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 # 33
Create a policy that ensures a ConfigMap exists with specific data
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Write a Policy # ConfigurationPolicy enforcing a ConfigMap (name, namespace, data keys).
* Bind to placement.
* Verify on a managed cluster:
oc get configmap -n < ns >
oc describe configmap -n < ns > < name >
NEW QUESTION # 34
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 # 35
Create a namespace for a team and bind a ManagedClusterSet to that namespace
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Create a namespace for the team:
oc new-project team-dev
* Create ManagedClusterSetBinding to bind ClusterSet development into team-dev:
cat < < 'EOF' | oc apply -f -
apiVersion: cluster.open-cluster-management.io/v1beta2
kind: ManagedClusterSetBinding
metadata:
name: development
namespace: team-dev
spec:
clusterSet: development
EOF
* Verify:
oc get managedclustersetbinding -n team-dev
Why this matters:
ClusterSet binding is foundational for scoping access and enabling teams to work only with clusters in their set.
NEW QUESTION # 36
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.
