KCNA Cloud Native Architecture Practice Question
A team wants to deploy a multi-cloud application that uses cloud-specific services. Which pattern is most appropriate?
⚠ Common exam trap
Watch out — candidates often think 'cloud-agnostic' means avoiding all cloud-specific services, but the correct pattern allows using them through abstraction layers, not eliminating them entirely.

Correct answer & explanation
✓
Using cloud-agnostic abstractions and infrastructure as code across providers
Using cloud-agnostic abstractions (e.g., Kubernetes for container orchestration, Terraform for infrastructure as code) allows the team to deploy across multiple clouds while still integrating cloud-specific services via provider-agnostic interfaces or abstraction layers. This pattern reduces vendor lock-in, enables consistent deployment workflows, and supports portability without sacrificing the ability to use unique services from each cloud provider.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Single-cloud vendor lock-in to reduce complexity
Why it's wrong here
This contradicts multi-cloud goals.
- ✗
Manually managing each cloud separately without automation
Why it's wrong here
This is inefficient and error-prone.
- ✗
Only using serverless functions from one provider
Why it's wrong here
This locks into one provider's serverless offering.
- ✓
Using cloud-agnostic abstractions and infrastructure as code across providers
Why this is correct
Tools like Terraform and Kubernetes enable portability across clouds.
