Reveal correct answer
Correct answer: B
Explanation
The command used to view information about all pods across all namespaces running on a Kubernetes cluster is:
kubectl get pods --all-namespaces
This command provides a comprehensive list of all pods, regardless of the namespace in which they are deployed, along with their current status, IP addresses, and other relevant details.

A. The command "kubectl describe pod all" is not the correct command to view information about all pods across all namespaces in a Kubernetes cluster. This command is used to describe a specific pod, not all pods, and it does not include the option to specify all namespaces.
B. The command "kubectl get pods --all-namespaces" is used to view information about all pods across all namespaces running on a Kubernetes cluster. This command provides a comprehensive overview of all pods in the cluster, regardless of the namespace they belong to.
C. The command "kubectl view pods" is not a valid command in Kubernetes. The correct command to view information about pods is "kubectl get pods" or "kubectl describe pods". Using an incorrect command like in this choice will result in an error and will not provide the desired information about all pods across all namespaces.
D. The command "kubectl describe pods-namespace all" is not a valid command in Kubernetes. The correct syntax for describing pods in a specific namespace is "kubectl describe pods -n ". Using incorrect syntax like in this choice will result in an error and will not provide the desired information.
