KCNA Kubernetes Fundamentals Practice Question
Which Kubernetes object is used to store non-sensitive configuration data that can be consumed by pods?
⚠ Common exam trap
Kubernetes often tests the distinction between ConfigMap and Secret, trapping candidates who assume all configuration data must be stored in Secrets, ignoring that ConfigMap is the correct choice for non-sensitive data.

Correct answer & explanation
✓
ConfigMap
ConfigMap is the correct Kubernetes object for storing non-sensitive configuration data, such as environment variables, command-line arguments, or configuration files, that can be consumed by pods. Unlike Secrets, ConfigMaps store data in plaintext and are designed for configuration that does not require encryption, making them ideal for application settings that are not confidential.
