What command will change the current context to use a specific namespace?

• A. kubectl set-context --current --namespace=mynamespace
• B. kubectl config set-context --current --namespace=mynamespace
• C. kubectl config use-context mynamespace
• D. kubectl config set-namespace mynamespace

Answer: (B)

Changing the default namespace for the current context means updating the kubeconfig so the active context uses that namespace by default. The context stores cluster, user, and namespace information, and kubectl uses the namespace from the current context when none is specified in a command. The correct approach is to modify the current context with: kubectl config set-context --current --namespace=mynamespace. This updates the namespace field of the active context, so subsequent kubectl commands will operate in mynamespace unless a different namespace is explicitly provided. The other options either try to switch contexts instead of setting the namespace, rely on a command form that may not be available in all versions, or are invalid.
