Which item is considered part of the Kubernetes control plane?

• A. Node
• B. Pod
• C. Kubelet
• D. Cloud-Controller-Manager

Answer: (D)

In Kubernetes, the control plane houses components that decide and manage the cluster’s overall state. The cloud-controller-manager is a control-plane component that runs cloud-provider specific controllers and talks to the cloud provider’s API to manage external resources (like load balancers, node lifecycles, and routes). It operates independently of any single node and coordinates cloud-related aspects of the cluster. The other options run on the worker nodes or as workloads: the node hosts run Kubelet, which is the agent on each node that boots and keeps containers running; a Pod is a scheduling unit that ends up running on a node; none of these are part of the control plane.
