KCNA Kubernetes Fundamentals Practice Question
What is the smallest deployable unit in Kubernetes?
⚠ Common exam trap
A common trap is to think that a Container is the smallest unit because it is the fundamental runtime entity, but Kubernetes abstracts containers inside Pods, making the Pod the smallest deployable and schedulable object.

Correct answer & explanation
✓
Pod
A Pod is the smallest and simplest unit in the Kubernetes object model. It represents a single instance of a running process in the cluster and encapsulates one or more containers with shared storage and network resources. Containers are not directly scheduled onto Nodes; instead, Kubernetes always schedules and manages Pods as the atomic unit of deployment.
