Dns — Certified Kubernetes App Developer (CKAD) Practice Questions
DNS in Kubernetes is provided by CoreDNS and gives every Service a predictable hostname in the form service-name.namespace.svc.cluster.local, allowing Pods to reach Services by name rather than IP address. The CKAD exam tests understanding of how to construct these DNS names, how namespace isolation affects name resolution, and how to verify DNS lookups from inside a running Pod. Correct use of DNS is essential for writing application configurations that reference other services reliably across restarts and scaling events.
