200-901 Application Deployment and Security Practice Question

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.

In a Kubernetes cluster, you need to store non-sensitive configuration data (e.g., database hostname) that can be consumed by pods as environment variables. Which resource should you use?

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

ConfigMap

A ConfigMap is the correct Kubernetes resource for storing non-sensitive configuration data like a database hostname. It is designed to decouple configuration artifacts from image content, allowing pods to consume this data as environment variables or mounted files without hardcoding values into container images.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ConfigMap

    Why this is correct

    ConfigMap is the correct resource for non-sensitive configuration data.

    Related concept

    Read the scenario before looking for a memorised answer.

  • PersistentVolume

    Why it's wrong here

    PersistentVolume is for storage, not configuration.

  • Secret

    Why it's wrong here

    Secrets are for sensitive data like passwords; using them for non-sensitive data is not best practice.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the distinction between ConfigMaps and Secrets, where the trap is that candidates confuse 'non-sensitive' with 'sensitive' and incorrectly choose Secrets for all configuration data, or they pick PersistentVolume because they think any data storage requires persistent volumes.

Detailed technical explanation

How to think about this question

ConfigMaps store data as key-value pairs or literal files, and pods reference them via envFrom or valueFrom.configMapKeyRef in the pod spec. Under the hood, ConfigMaps are stored in etcd and can be updated without restarting pods if consumed as mounted volumes, but environment variable changes require a pod restart. A real-world scenario is storing database hostnames, API endpoints, or feature flags that vary across environments (dev, staging, prod) without rebuilding container images.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

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.
