A cluster administrator is troubleshooting a situation where the Kubernetes API server is unresponsive. The administrator suspects that etcd is experiencing performance issues. Which action should the administrator take to confirm this diagnosis?

Inspect the scheduler logs for failed scheduling attempts

Check the etcd metrics and logs on the control plane nodes

Restart the kubelet on all worker nodes

Check the kube-proxy configuration on the nodes

What is the purpose of a StorageClass in Kubernetes?

To provide a way to dynamically provision PersistentVolumes with specific characteristics

To define the desired state of a storage volume

To bind a PersistentVolumeClaim to a specific PersistentVolume

To store the contents of a volume in a key-value store

A security team requires that all pods in a specific namespace run with a read-only root filesystem and cannot run as the root user. They also want to enforce this at the API level so that non-compliant pods are rejected. Which combination of resources should they use?

A ResourceQuota with a limit on CPU and memory

A RoleBinding that grants the 'edit' role to developers

A PodSecurity admission controller with a restricted policy applied to the namespace

A NetworkPolicy that blocks all ingress traffic
