  1. Which Service type exposes a service only within the Kubernetes cluster on an internal IP?

    Answer: ClusterIP

    ClusterIP is the default service type that assigns an internal cluster IP, making the service reachable only within the cluster.

  2. Which Service type exposes an application on a static port on every node's IP?

    Answer: NodePort

    NodePort exposes the service on each Node's IP at a static port in the range 30000–32767.

  3. What is the default port range for NodePort services in Kubernetes?

    Answer: 30000–32767

    NodePort services allocate ports from the range 30000–32767 by default, configurable via `--service-node-port-range` on the API server.

  4. Which Service type automatically provisions an external cloud load balancer?

    Answer: LoadBalancer

    The LoadBalancer service type requests an external load balancer from the cloud provider to route traffic to the service.

  5. What does setting `clusterIP: None` on a Service create?

    Answer: A Headless Service for direct pod DNS discovery

    Setting `clusterIP: None` creates a Headless Service that returns individual pod IPs via DNS instead of a single virtual IP.

  6. Which Service type creates a DNS CNAME alias pointing to an external hostname?

    Answer: ExternalName

    ExternalName service maps a Kubernetes service to an external DNS name by returning a CNAME record for the configured hostname.
