A pod named 'worker-0' is stuck in the 'ContainerCreating' state. You've already checked the pod's events and see 'FailedMount' errors. You need to see the detailed volume mount configuration and the exact error message from the kubelet. Which command provides the most detailed information?

kubectl get pod worker-0 -o yaml

A pod named 'api' is in a CrashLoopBackOff state. You've checked the logs and found an 'OOMKilled' message. You need to confirm whether the OOM kill was due to the container exceeding its memory limit or the node running out of memory. Which combination of commands provides the most definitive evidence?

kubectl logs api --previous | grep -i oom

kubectl events --for pod/api | grep -i oom

kubectl describe pod api | grep -A5 'State' && kubectl top node

kubectl get pod api -o yaml | grep -i 'memory'

Your team reports that a node is running hot and applications are becoming slow. You need to see which pods on that specific node are consuming the most CPU to identify the culprit. Which command provides this information?

kubectl get pods -o wide --field-selector spec.nodeName=node-01

kubectl top pods --field-selector spec.nodeName=node-01 --sort-by=cpu

A pod named 'worker' runs a long-lived process that prints progress updates to stdout. You want to watch the live output stream and send an interrupt signal (Ctrl+C) to the process if it hangs. Which command allows you to interact with the container's standard streams?

kubectl exec -it worker -- /bin/sh

kubectl port-forward pod/worker 8080:8080

You are debugging a webhook receiver in a pod named 'webhook' that listens on port 8443. The pod is in a namespace 'dev'. You need to send a test HTTPS request to it from your local machine. The pod's service is named 'webhook-svc'. Which command allows you to test this locally?

kubectl exec -n dev webhook -- curl https://localhost:8443

kubectl port-forward -n dev service/webhook-svc 8443:8443

kubectl expose -n dev pod webhook --port=8443 --type=NodePort
