Certified Kubernetes Administrator (CKA) Practice Test

The command to delete a resource in Kubernetes is "kubectl delete resource." This command is essential for managing resources within a Kubernetes cluster. It allows administrators to specify the type of resource they want to delete (for example, pods, services, deployments) along with the name or labels to identify which specific resource to remove.

When using this command, you may also specify additional options, such as `--grace-period` to control the grace period before the resource is forcibly deleted, or `--force` to immediately remove the resource without waiting for graceful termination. The flexibility and functionality of the "kubectl delete" command make it a critical tool for Kubernetes cluster management.

The other options presented do not exist as valid commands in Kubernetes. For instance, "kubectl remove" and "kubectl destroy" do not correspond to any recognized commands for managing Kubernetes resources. Similarly, "kubectl purge" is not a valid command related to resource manipulation within Kubernetes. Understanding the correct command is fundamental for performing deletions effectively in a Kubernetes environment.
