KCNA Cloud Native Architecture Practice Question
Which resource in Kubernetes is used to expose a set of pods as a network service?
⚠ Common exam trap
CNCF often tests the misconception that a Deployment can expose pods as a network service, but a Deployment only manages pod lifecycle and replicas, not network exposure.

Correct answer & explanation
✓
Service
A Service in Kubernetes provides a stable network endpoint (IP address and DNS name) to expose a set of pods, which are ephemeral and can be replaced. Services use selectors to identify target pods and load-balance traffic across them, enabling reliable communication within or outside the cluster.
