Services and Networking on the CKAD exam tests how application traffic is exposed and routed inside and outside a Kubernetes cluster using Services (ClusterIP, NodePort, LoadBalancer), Ingress resources, and NetworkPolicies. Candidates must be comfortable creating Services to front Pods, writing Ingress rules with appropriate host and path routing, and defining NetworkPolicy manifests to restrict pod-to-pod traffic. This domain directly reflects the work an application developer must do to make a deployed workload reachable and properly isolated.
