Services — Certified Kubernetes App Developer (CKAD) Practice Questions
In Kubernetes, a Service is an abstraction that provides a stable network endpoint for accessing one or more Pods, which may come and go as deployments scale or restart. Services decouple the consumer of an application from the underlying Pod IP addresses, which are ephemeral by nature. The CKAD exam tests your ability to create and configure ClusterIP, NodePort, and LoadBalancer service types, map ports correctly, and use label selectors to route traffic to the right Pods. Understanding how Services enable communication both within a cluster and with external clients is essential for application deployment tasks on the exam.
