Which tool do you use to administer a NetApp Kubernetes Service cluster manager?

• A. kubectl
• B. kubeadm
• C. Docker
• D. Helm

Answer: (B)

The tool you use to bootstrap and manage a Kubernetes cluster is kubeadm. It is designed to initialize the control plane, join worker nodes to the cluster, and handle essential cluster lifecycle tasks. In the context of a NetApp Kubernetes Service cluster manager, kubeadm provides the orchestration needed to set up and maintain the cluster itself.

Kubectl is the day-to-day client you run after the cluster is up to interact with the Kubernetes API server and manage resources inside the cluster. Docker (the container runtime) is what runs the containers on each node, not a cluster-management tool. Helm is a package manager for deploying applications into Kubernetes, not for provisioning or administering the cluster infrastructure itself.

So kubeadm is the appropriate tool for administering the cluster manager, since it covers the cluster’s bootstrap and lifecycle responsibilities.
