A container repeatedly restarts with CrashLoopBackOff. Which command shows the output from the previous, failed container instance?
Answer: A
The --previous flag retrieves logs from the last terminated instance of the container, which is where the crash reason usually appears. The current instance may have no useful output yet if it fails immediately on start.
A node shows status NotReady. Which service should be checked first on that node?
Answer: A
A node reports Ready through its kubelet, so a NotReady node usually means the kubelet has stopped, cannot reach the API server, or the container runtime beneath it has failed. etcd and the API server run on control plane nodes, and CoreDNS is a cluster add-on.
