In kubectl, what does the -A flag do when listing resources?

• A. All namespaces
• B. All pods
• C. All nodes
• D. All resources

Answer: (A)

The flag expands the scope to include every namespace. It’s shorthand for --all-namespaces, so when you list resources with it, kubectl queries all namespaces in the cluster instead of just the current one. For example, kubectl get pods -A will show pods from every namespace. Keep in mind some resources aren’t namespaced (like nodes), so -A doesn’t change their scope in the same way, but for namespaced resources it clearly broadens the view to all namespaces.
