KCNA Container Orchestration Practice Question
Which TWO of the following are characteristics of a microservices architecture? (Select 2)
⚠ Common exam trap
CNCF often tests the misconception that microservices require a shared database for consistency, but the correct pattern is database-per-service to maintain loose coupling and independent scalability.
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
✓
Independent deployment of services
Microservices architecture is designed to allow each service to be developed, tested, and deployed independently without affecting other services. This independence is achieved through well-defined APIs and versioning strategies, enabling continuous delivery and rapid iteration. In Kubernetes, for example, each microservice can be packaged as a separate container and deployed via its own Deployment resource, allowing updates to one service without downtime for the entire application.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Independent deployment of services
Why this is correct
Each microservice can be deployed independently.
- ✗
Tight coupling between services
Why it's wrong here
Microservices are loosely coupled.
- ✓
Loose coupling between services
Why this is correct
Microservices communicate via APIs and are loosely coupled.
- ✗
Monolithic codebase
Why it's wrong here
Microservices decompose into smaller services.
- ✗
Shared database for all services
Why it's wrong here
Microservices often have their own databases.
