What command would you use to retrieve the cluster's metadata information?

get cluster-info
describe cluster
fetch cluster-info
cluster-info

The correct answer is: get cluster-info

The command used to retrieve the cluster's metadata information is "kubectl cluster-info". This command provides essential details about the cluster, including information about the control plane and services running within the cluster. It summarizes the endpoints for the Kubernetes control plane components, allowing administrators and developers to quickly access key addresses and verify the operational state of their Kubernetes environment. This command is specifically designed for fetching cluster metadata, making it the most relevant choice. Other options listed do not represent valid Kubernetes commands or are incorrectly specified. For instance, while "describe" is a valid command in Kubernetes, it is typically used to obtain detailed information about specific resources like pods or nodes based on their names, rather than general cluster metadata. Similarly, "fetch cluster-info" and "cluster-info" do not correspond to any recognized command in Kubernetes, reinforcing the correctness of using "kubectl cluster-info" to obtain cluster metadata.
