If you run a command without specifying a namespace in Kubernetes, which namespace will it run in?

• A. kube-system
• B. production
• C. default
• D. default-namespace

Answer: (C)

When you run a Kubernetes command without specifying a namespace, kubectl uses the namespace defined in your current context. If no namespace is configured there, it defaults to the built-in namespace called default. That’s why the operation happens in the default namespace unless you explicitly set a different one with -n or --namespace, or by changing the context. The kube-system namespace hosts system components, while production would be a user-created namespace, and default-namespace isn’t a standard Kubernetes namespace.
