KCNA Container Orchestration Practice Question
Which of the following is a benefit of container orchestration?
⚠ Common exam trap
CNCF often tests the misconception that orchestration provides absolute guarantees (like zero downtime or complete security), when in reality it provides mechanisms to improve reliability and security but cannot eliminate all risks.

Correct answer & explanation
✓
Self-healing of failed containers
Container orchestration platforms like Kubernetes provide self-healing capabilities by automatically restarting failed containers, rescheduling them on healthy nodes, and replacing or terminating containers that fail health checks. This ensures that the desired state of the application is maintained without manual intervention, which is a core benefit of orchestration.
