Which THREE are valid methods for managing Kubernetes application configuration?
⚠ Common exam trap
Cisco often tests the distinction between build-time configuration (Dockerfile ENV) and runtime configuration (ConfigMaps, Secrets, Helm values), trapping candidates who think environment variables in the Dockerfile are a valid runtime management method for Kubernetes.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Helm values.
Helm values (A) are correct because Helm is a package manager for Kubernetes that uses values.yaml files to inject configuration into templates at deployment time, enabling dynamic, environment-specific application configuration without modifying the underlying chart. This is a standard method for managing Kubernetes application configuration in production workflows.
