Certified Kubernetes Administrator (CKA) Practice Test

The 'kubectl describe' command is used to provide detailed information about a specific resource in the Kubernetes cluster. When you run this command followed by the resource type and name, it presents an in-depth view that includes various details like the resource's current state, metadata, labels, annotations, and events related to the resource. This granular level of detail is useful for troubleshooting and understanding the configuration and status of specific elements within your Kubernetes environment.

The other options don't accurately reflect the primary output of the 'kubectl describe' command. For instance, while basic statistics about nodes, lists of running Pods, and all events in the cluster can be obtained through other `kubectl` commands, they are not what 'kubectl describe' specifically aims to provide. Each of those can be accessed through commands like 'kubectl get nodes,' 'kubectl get pods,' or 'kubectl get events,' respectively.
