RedHat Red Hat Certified Specialist in OpenShift Automation and Integration Sample Questions (Q29-Q34):

NEW QUESTION # 29
Configure resiliency using a PodDisruptionBudget
Task Information : Ensure at least 2 replicas of payments/api remain available during voluntary disruptions.

Answer:

Explanation:
See the solution below in Explanation:
Explanation:
* Create PDB
* cat < < EOF | oc -n payments apply -f -
* apiVersion: policy/v1
* kind: PodDisruptionBudget
* metadata:
* name: api-pdb
* spec:
* minAvailable: 2
* selector:
* matchLabels:
* app: api
* EOF
* minAvailable: 2 blocks evictions that would reduce availability below 2.
* Verify PDB
* oc -n payments get pdb
* oc -n payments describe pdb api-pdb


NEW QUESTION # 30
Add tolerations to a deployment
Task Information : Update payments/api deployment to tolerate dedicated=payments:NoSchedule.

Answer:

Explanation:
See the solution below in Explanation:
Explanation:
* Patch deployment with toleration
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"tolerations":[
* {"key":"dedicated","operator":"Equal","value":"payments","effect":"NoSchedule"}
* ]}}}
* }'
* Toleration allows pods to schedule onto tainted nodes.
* Verify scheduling
* oc -n payments get pods -o wide


NEW QUESTION # 31
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.

Answer:

Explanation:
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 >


NEW QUESTION # 32
Restore application into same namespace
Task Information : Restore from backup orders-full and validate the app resources return.

Answer:

Explanation:
See the solution below in Explanation:
Explanation:
* Start the restore
* velero restore create orders-restore --from-backup orders-full
* Monitor restore status
* velero restore get
* velero restore describe orders-restore --details
* Validate restored resources
* oc -n orders get all
* oc -n orders get pvc
* Ensure deployments/pods/services and PVCs exist and pods become Running.


NEW QUESTION # 33
Kubeconfig Management - Set Context in Kubeconfig

Answer:

Explanation:
See the solution below in Explanation:
Explanation:
Step 1: Verify the cluster name, namespace, and user name that should be referenced.
The lab uses cluster api-ocp4-example-com:6443, namespace audit-ns, and user audit-sa.
Step 2: Run the command:
oc config set-context audit --cluster api-ocp4-example-com:6443 --namespace audit-ns --user audit-sa -- kubeconfig audit.config Step 3: Confirm context creation.
The lab output shows:
Context "audit" created.
Detailed explanation:
A kubeconfig context ties together three things: a cluster endpoint, a user identity, and optionally a default namespace. This Task creates a context named audit in the file audit.config. Contexts are useful because they simplify repeated administration by letting the user switch between prepared working environments instead of re-entering cluster and namespace details each time. The namespace portion is especially helpful for project- scoped operations, because commands run under that context default to the chosen namespace. Accuracy matters here: if the user name in the context does not match the credentials entry or the cluster name does not exist in the kubeconfig, the context will not function as intended.
