KCNA Cloud Native Architecture Practice Question
A company is adopting a multi-cloud strategy to avoid vendor lock-in. Which pattern BEST supports deploying applications across different cloud providers with minimal changes?
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
✓
Deploy applications using Kubernetes on each cloud
Using Kubernetes as a consistent abstraction layer allows applications to run across different cloud providers with minimal modifications since it uses a common API and container orchestration. Cloud-specific APIs would lock you in, and hybrid cloud typically refers to mixing public and private cloud, not necessarily multi-cloud.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a hybrid cloud approach with a single cloud for all workloads
Why it's wrong here
Hybrid cloud involves private and public cloud, but does not address multi-cloud portability.
- ✓
Deploy applications using Kubernetes on each cloud
Why this is correct
Kubernetes provides a portable platform that abstracts underlying infrastructure differences.
- ✗
Use each cloud provider's native services directly
Why it's wrong here
This would tightly couple the application to the provider's APIs, making portability difficult.
- ✗
Write application code that checks the cloud provider and adapts
Why it's wrong here
This is complex and error-prone; it violates the principle of separation of concerns.
