KCNA Container Orchestration Practice Question
Which TWO of the following are benefits of using a container orchestration platform like Kubernetes? (Select 2)
⚠ Common exam trap
A common misconception is that container orchestration requires hypervisors or static infrastructure, but the correct understanding is that Kubernetes abstracts the underlying hardware and provides dynamic, self-healing, and auto-scaling capabilities without hypervisors.

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
✓
Self-healing of failed containers
Kubernetes includes a built-in controller loop that continuously monitors the desired state of workloads. If a container or pod fails, the ReplicaSet or StatefulSet controller automatically replaces it by rescheduling a new pod, ensuring application availability without manual intervention.
