KCNA Kubernetes Fundamentals Practice Question
You need to provide an application with configuration data that does not change often and should not be baked into the container image. Which Kubernetes resource should you use?
⚠ Common exam trap
Watch out — candidates often confuse ConfigMap with Secret, assuming all configuration must be secret, or they mistakenly think PersistentVolumeClaim can store configuration files, when in fact ConfigMap is the correct resource for non-sensitive, frequently updated configuration data.

Correct answer & explanation
✓
ConfigMap
ConfigMap is the correct Kubernetes resource for providing configuration data that does not change often and should not be baked into the container image. It decouples configuration artifacts from image content, allowing you to update configuration without rebuilding images, and supports injection via environment variables, command-line arguments, or volume mounts.
