AI translates the explanation and quiz text while preserving code and answer scoring.

Because Pods are ephemeral with dynamic IPs, Services provide stable virtual IPs and DNS names. - ClusterIP: Internal-only cluster communication (default). - NodePort: Exposes static port on every Node's IP. - LoadBalancer: Provisions cloud-provider load balancers. - Ingress / Gateway API: Application-layer (L7) reverse proxy routing, SSL/TLS termination, and path-based routing.
