Certified Kubernetes Application Developer (CKAD) Practice Test

The command used to list the nodes in a Kubernetes cluster is "kubectl get nodes." This command is part of the Kubernetes command-line interface (kubectl), which is primarily used to interact with the Kubernetes API server. When you execute this command, it returns a list of all the nodes currently registered in the cluster, along with relevant information such as their status, roles, age, and version of Kubernetes they are running.

Using "get" is consistent with the general pattern of kubectl commands, where "get" is the action for retrieving and listing resources. This structured approach helps users quickly understand the functionalities available for interacting with various Kubernetes objects.

Options that mention "list," "show," or "view" do not reflect the correct syntax used by kubectl to perform this action, indicating a misunderstanding of how to utilize the command-line tool effectively. Understanding the correct command and its structure is crucial for managing Kubernetes resources efficiently.
