"description": "## Essential kubectl Commands\n\nYou need to quickly view the **logs** of a container named `api` inside a pod named `backend-7d9f`. The pod has multiple containers.\n\nWhich command is correct?",

"explanation": "When a pod has **multiple containers**, you must specify which container's logs you want using the `-c <container-name>` flag: `kubectl logs <pod-name> -c <container-name>`. Without `-c`, kubectl returns an error if the pod has more than one container. `kubectl describe` shows metadata and events, not live logs. `kubectl exec` can work but is cumbersome and container-runtime dependent.",
