A city permits microservice must be reachable by other in-cluster clients only, not published on node or cloud load-balancer fronts. Which Service type fits?
Select an answer to reveal the explanation.
Short Explanation
ClusterIP is the internal desk phone number—great for coworkers in the building, not listed in the public directory. Other Pods dial the Service DNS; you don’t get a node port or cloud LB unless you ask for those types.
Full Explanation
ClusterIP is the default Service type and exposes the application on a virtual cluster-internal IP for in-cluster clients. NodePort and LoadBalancer publish the Service more widely on nodes or via an external load balancer. ExternalName maps to an external DNS name and does not select Pods as backends for this internal API use case.
