Users report that the Kubernetes API is intermittently unavailable. You check the kube-apiserver pod and see it is restarting frequently. The kube-apiserver logs show repeated 'etcdserver: request timed out' errors. What is the most likely root cause?

The kube-scheduler is failing to place pods

The kube-controller-manager is not syncing resources

The kubelet on the control plane node is not reporting status

The etcd cluster is experiencing performance issues or is unreachable

You are investigating a cluster where the API server is slow to respond. Which metric would most directly indicate a problem with the API server's ability to persist state?

The network latency between worker nodes

etcd's fsync duration and leader election status

The CPU usage of the kube-scheduler

The number of pods in the cluster

A node has been NotReady for 10 minutes. You need to perform maintenance on it. Which sequence of actions is most appropriate?

Reboot the node without draining

Delete the node object and recreate it after maintenance

Cordon the node, drain it, perform maintenance, then uncordon

Drain the node, then immediately reboot it
