KCNA Kubernetes Fundamentals Practice Question
Which TWO of the following are true about Kubernetes Pods?
⚠ Common exam trap
Many exam-takers confuse the Pod's ability to run multiple containers with the requirement to run exactly one, or they mistakenly think the scheduler creates Pods instead of only assigning them to nodes.
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 basic deployable unit in Kubernetes. It represents a single instance of a running process and encapsulates one or more containers, storage resources, and a unique network IP. You cannot deploy a container directly; you must always wrap it in a Pod.

- ✗
A Pod always runs exactly one container
Why it's wrong here
A Pod can run one or more containers.
- ✗

A Pod is the smallest deployable unit in Kubernetes
Why this is correct
Pods are the smallest and simplest Kubernetes object.
- ✓
Containers within the same Pod share the same network namespace
Why this is correct
