KCNA Kubernetes Fundamentals Practice Question
Which command would you use to view the logs of a container named 'sidecar' inside a pod named 'app'?
⚠ Common exam trap
The trap is that candidates may assume the container name can be passed as a second positional argument instead of using the `-c` flag.

Correct answer & explanation
✓
kubectl logs app -c sidecar
The `kubectl logs` command uses the `-c` flag to specify a container name within a pod. When a pod contains multiple containers, you must explicitly indicate which container's logs to retrieve. The syntax `kubectl logs <pod-name> -c <container-name>` is the standard way to view logs from a specific container in a multi-container pod.
