This 200-901 practice question tests your understanding of application deployment and security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE are valid methods for managing Kubernetes application configuration?
Helm values.
Used in Helm charts for template configuration.
Secrets.
Store sensitive data like passwords.
Operator custom resources.
Why wrong: Used to manage custom applications, not general config.
Environment variables in the Dockerfile.
Why wrong: Baked into the image, not manageable by Kubernetes.
ConfigMaps.
Store non-sensitive configuration data.
Answer choices
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
ConfigMaps and Secrets store configuration data as key-value pairs or files in etcd, and are mounted into pods as environment variables or volumes. Helm values leverage Go templates to dynamically render Kubernetes manifests, allowing overrides via --set flags or multiple values files (e.g., values-prod.yaml). This separation of configuration from code aligns with the Twelve-Factor App methodology, ensuring portability across environments.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
