Application Configuration — Certified Kubernetes App Developer (CKAD) Practice Questions

Application configuration in Kubernetes focuses on how containers receive runtime parameters, connection strings, feature flags, and credentials needed to operate correctly. ConfigMaps hold plaintext key-value pairs while Secrets hold base64-encoded sensitive data, and both can be injected into pods via environment variables, command-line arguments, or volume mounts. CKAD candidates must understand the precedence rules and lifecycle of these configuration objects because misconfigured or missing values are a common source of application failures in the exam environment.
