Where is the cluster configuration for kubectl stored?

• A. Kubeconfig file
• B. Etcd
• C. Kubelet config
• D. Pod manifest

Answer: (A)

kubectl reads its cluster connection information from the kubeconfig file, typically located at ~/.kube/config (or any file specified by the KUBECONFIG environment variable). This file holds one or more clusters, user credentials, and contexts that tie a cluster to a user, with the current-context indicating which cluster and user to use by default. In short, kubectl’s client configuration, including the API server URL and authentication details, lives in the kubeconfig file. The other options serve different purposes: etcd is the cluster’s internal data store, not a client config; kubelet config relates to the node agent on each node; pod manifests are definitions of pods to run, not where kubectl stores its config.
