NEW QUESTION # 17
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 # 18
Create a Placement for production clusters and limit placement to 2 clusters
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
* Label clusters for prod:
oc label managedcluster cluster-prod1 environment=prod --overwrite
oc label managedcluster cluster-prod2 environment=prod --overwrite
* Create Placement with numberOfClusters: 2:
cat < < 'EOF' | oc apply -f -
apiVersion: cluster.open-cluster-management.io/v1beta1
kind: Placement
metadata:
name: prod-two-clusters
namespace: team-prod
spec:
numberOfClusters: 2
predicates:
- requiredClusterSelector:
labelSelector:
matchLabels:
environment: prod
EOF
* Validate placement decisions:
oc get placementdecision -n team-prod
NEW QUESTION # 19
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.
