KCNA Cloud Native Architecture Practice Question
An organization wants to adopt a cloud-native approach for its new application. Which characteristic is most important for the application to be considered cloud-native?
⚠ Common exam trap
CNCF often tests the misconception that cloud-native simply means 'running in containers' or 'using Kubernetes,' but the defining characteristic is the architectural property of being resilient, scalable, and manageable in a dynamic environment, not the deployment technology itself.

Correct answer & explanation
✓
It is designed to be resilient, scalable, and manageable in a dynamic environment.
Cloud-native applications are fundamentally defined by their ability to operate in dynamic, distributed environments. They leverage principles like microservices, containerization, and orchestration (e.g., Kubernetes) to achieve resilience, scalability, and manageability. This characteristic is the core tenet of cloud-native architecture as defined by the CNCF, enabling the app to handle failures gracefully and scale on demand.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It stores all state in local files on the container filesystem.
Why it's wrong here
Stateful applications should use external storage, not rely on ephemeral container filesystems.
- ✓
It is designed to be resilient, scalable, and manageable in a dynamic environment.
Why this is correct
Resilience, scalability, and manageability are core cloud-native characteristics.
- ✗
It runs as a single monolithic process for simplicity.
Why it's wrong here
Monolithic architecture contradicts the microservices principle of cloud-native.
- ✗
It is deployed exclusively on on-premises infrastructure.
Why it's wrong here
Cloud-native embraces public, private, and hybrid clouds, not just on-premises.
