What does the command 'kubectl expose' do in Kubernetes?

• A. Decreases a deployment
• B. Exposes a Kubernetes deployment as a service
• C. Deletes a service
• D. Scales a deployment

Answer: (B)

Exposing a deployment by creating a Service object is what this command does. It takes the specified resource (like a Deployment) and creates a Service that selects the pods with the matching labels, giving them a stable network endpoint inside the cluster. By default, this creates a ClusterIP service, which is reachable from within the cluster only; you can make it accessible outside the cluster by choosing a different type, such as NodePort or LoadBalancer. This operation does not change the number of replicas, delete resources, or scale the deployment.
