Which component is NOT a Kubernetes control plane component?

Which component is NOT a Kubernetes control plane component?

• A. Cloud-Controller-Manager
• B. Kube-Api Server
• C. ETCD
• D. Kubelet

Answer: (D)

The control plane consists of components that manage the cluster’s desired state: the API server that exposes the Kubernetes API, etcd as the backing store, and controllers like the cloud-controller-manager. The kubelet is a node-level agent that runs on every worker node, ensuring pods are started and healthy and reporting node status back to the API server. It is not part of the central control plane, which is why kubelet is the correct choice for what is NOT a control plane component.
