Real Exam
Explanation:
The correct answer is D because it exposes the service on a cluster-internal IP address, making it accessible only within the cluster. This meets the requirement of not exposing Deployment-A outside the cluster.
- Option A is incorrect as it would expose Deployment-A over the public internet.
- Option B is incorrect because using a LoadBalancer would expose the service publicly.
- Option C is incorrect as it involves exposing the service externally using a cloud provider's load balancer, and Ingress does not work with LoadBalancer.
