Certified Kubernetes Administrator (CKA) Practice Test

Question: 1 / 400

What command would you use to assess overall health checks of the Kubernetes components?

kubectl health check

kubectl get components

kubectl get componentstatuses

The command used to assess the overall health checks of the Kubernetes components is "kubectl get componentstatuses." This command retrieves the statuses of various key components in the Kubernetes cluster, such as the API server, controller manager, scheduler, etc. By executing this command, you get a clear overview of whether each component is healthy and operational, as it returns information on the current state of essential services that run within the cluster.

This command is particularly useful for cluster administration because it helps ensure that all core components are functioning correctly, which is fundamental to maintaining the overall health and reliability of the Kubernetes environment. The output typically includes the name of each component along with its status, allowing administrators to quickly diagnose issues or confirm that everything is running smoothly.
