KCNA Kubernetes Fundamentals Practice Question
You need to provide configuration data as environment variables to a pod, but the data is not sensitive. Which object should you use?
⚠ Common exam trap
Many candidates confuse ConfigMap with Secret, assuming that any data passed as environment variables must be sensitive, or they overlook that ServiceAccounts are for identity, not configuration data.

Correct answer & explanation
✓
ConfigMap
A ConfigMap is the correct Kubernetes object for providing non-sensitive configuration data as environment variables to a pod. ConfigMaps are designed to decouple configuration artifacts from image content to keep containers portable, and they support injection via environment variables, command-line arguments, or volume mounts. Unlike Secrets, ConfigMaps store data in plaintext (base64-encoded only for transport) and are intended for data that does not require encryption at rest or in transit.
