Externalname — Certified Kubernetes App Developer (CKAD) Practice Questions
ExternalName is a Kubernetes Service type that maps a Service name inside the cluster to an external DNS hostname rather than to pod endpoints. When a pod queries the Service name, the cluster DNS returns a CNAME record pointing to the configured external host, allowing applications to reference external services using consistent internal names. CKAD candidates need to understand ExternalName Services because they are a common pattern for integrating cluster workloads with databases or APIs hosted outside Kubernetes.
