KCNA Kubernetes Fundamentals Practice Question
Which TWO of the following are true about Kubernetes Pods?
⚠ Common exam trap
Watch out — candidates often confuse Pods with virtual machines, assuming each container gets its own IP and filesystem isolation, when in fact Pods are designed for tight coupling and shared resources.
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
✓
A pod is the smallest deployable unit in Kubernetes
A Pod is the smallest and most fundamental deployable unit in Kubernetes. It represents a single instance of a running process in the cluster and encapsulates one or more containers with shared storage and network resources. You cannot deploy a container directly; you must always wrap it in a Pod.
