質問 # 39
Create an Argo CD Application (OpenShift GitOps)
Task Information : Create an Argo CD Application that syncs from Git into namespace gitops-demo with automated sync enabled.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Create target namespace
* oc new-project gitops-demo
* Destination must exist (unless Argo is configured to auto-create).
* Create Application manifest
* apiVersion: argoproj.io/v1alpha1
* kind: Application
* metadata:
* name: demo-app
* namespace: openshift-gitops
* spec:
* project: default
* source:
* repoURL: https://git.example.com/org/repo.git
* targetRevision: main
* path: manifests/demo
* destination:
* server: https://kubernetes.default.svc
* namespace: gitops-demo
* syncPolicy:
* automated:
* prune: true
* selfHeal: true
* automated: enables auto sync.
* prune: removes deleted objects from Git.
* selfHeal: corrects drift.
* Apply Application
* oc apply -f demo-app.yaml
* Verify sync health
* oc -n openshift-gitops get application demo-app -o yaml | grep -i -E "sync|health" -n
* oc -n gitops-demo get all
質問 # 40
Configure project-wide default tolerations
Task Information : Configure the payments namespace so new pods automatically include a default toleration.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Annotate the namespace with default tolerations
* oc annotate ns payments \
* scheduler.alpha.kubernetes.io/defaultTolerations='[{"key":"dedicated","operator":"Equal","value":" payments","effect":"NoSchedule"}]' \
* --overwrite
* Some clusters honor this pattern; if not, the fallback is mutating admission or editing workloads.
* Create a new pod/deployment in the namespace
* Then verify its spec includes tolerations:
* oc -n payments get pod < pod > -o yaml | grep -n tolerations -A5
質問 # 41
Recover a NotReady worker node (basic remediation workflow)
Task Information : Diagnose a NotReady worker node and restore it to Ready state using standard OpenShift admin workflow.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Identify failing node and status
* oc get nodes
* Confirms which node is NotReady.
* Inspect node conditions and events
* oc describe node < worker >
* Shows kubelet condition issues (network, disk pressure, runtime, etc.).
* Check MachineConfigPool state
* oc get mcp
* oc describe mcp worker
* If MCP is degraded, node may be stuck applying a config.
* Check node logs (kubelet)
* oc adm node-logs < worker > --path=kubelet.log
* Often reveals why node isn't reporting Ready.
* Remediate based on symptom
* Examples:
* If out of disk: free space, then verify kubelet recovers.
* If stuck MCO: investigate current/desired config and fix broken MachineConfig.
* If node cordoned/drained incorrectly: uncordon after remediation.
* oc adm uncordon < worker >
* Confirm node returns Ready
* oc get node < worker >
質問 # 42
Dedicate nodes to a workload using labels and nodeSelector
Task Information : Label two nodes with workload=payments and schedule a deployment only onto those nodes.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Label the chosen worker nodes
* oc label node worker-1 workload=payments
* oc label node worker-2 workload=payments
* Node labels are key/value metadata used by the scheduler.
* Add a nodeSelector to the deployment
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"nodeSelector":{"workload":"payments"}}}}
* }'
* Forces pods to schedule only to nodes that match the label.
* Verify placement
* oc -n payments get pods -o wide
* Confirms pods are running on the intended nodes.
質問 # 43
Install OADP Operator and verify Velero components
Task Information : Install the OADP operator and confirm Velero pods/components are running.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Install OADP via Web Console
* Operators # OperatorHub # search OADP / OpenShift API for Data Protection # Install
* Explanation: This operator manages Velero and backup integrations.
* Verify the operator CSV is installed
* oc get csv -A | grep -i -E "oadp|data protection|velero"
* Confirms installation succeeded.
* Verify pods in the OADP namespace (commonly openshift-adp)
* oc get pods -n openshift-adp
* You should see Velero/OADP-related pods in Running state.
