What Kubernetes resource provides a stable entry point and can load balance across a set of pods?

• A. Deployment
• B. Service
• C. Ingress
• D. StatefulSet

Answer: (B)

A Kubernetes Service provides a stable entry point and load-balances traffic across a set of pods. It exposes a fixed DNS name and IP, decoupled from the lifecycle of any individual Pod, and targets pods via a label selector. When requests reach the Service, kube-proxy distributes them among healthy backend pods, giving you simple, ongoing load balancing. The Service can be configured as ClusterIP (default, internal), NodePort (exposes on each node), or LoadBalancer (provisions an external load balancer in many cloud environments), aligning exposure with your needs. Ingress sits above Services for HTTP routing and usually relies on a Service as the backend, rather than providing the stable entry point on its own. StatefulSet focuses on stable Pod identities and storage rather than a generic load-balanced endpoint for a pod pool. Deployment manages pod lifecycles but does not by itself offer a stable entry point or load balancing across pods.
