KCNA Kubernetes Fundamentals Practice Question
Which Kubernetes object provides stable network endpoints and load balancing for a set of pods?
⚠ Common exam trap
A common mix-up: candidates confuse a Deployment's ability to manage replicas with providing network access, forgetting that only a Service creates a stable, load-balanced network abstraction over pods.
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
✓
Service
A Service is the correct Kubernetes object because it provides a stable virtual IP (ClusterIP) and DNS name that remains constant even as pods are created or destroyed. It automatically load-balances traffic across the set of pods matching its label selector using iptables or IPVS rules, ensuring reliable network endpoints for clients.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Service
Why this is correct
Services provide stable IPs and DNS names with load balancing across pods.
- ✗
Deployment
Why it's wrong here
A Deployment manages replica sets and rolling updates, but does not provide a stable network endpoint.
- ✗
ConfigMap
Why it's wrong here
ConfigMaps store configuration data, not network endpoints.
- ✗
Pod
Why it's wrong here
Pods are ephemeral and their IPs can change; they do not provide stable endpoints.

Variation 1. Which Kubernetes object provides stable network endpoints and load balancing for a set of pods?
easy- A.Deployment
- B.ConfigMap
- ✓ C.Service
- D.Pod
Why C: A Kubernetes Service provides a stable virtual IP (ClusterIP) and DNS name that remains constant even as Pods are created or destroyed. It uses label selectors to identify target Pods and performs TCP/UDP load balancing across them, ensuring reliable network access without requiring clients to track ephemeral Pod IPs.
