Focused, hands-on DevOps and server-side problems with hints, feedback, and automated solution checks.

Challenge

Extend the Cluster with an Additional Service CIDR for the dev Team

Add a new, separate Service CIDR range for the dev team using the ServiceCIDR API object — without touching or restarting the cluster's default Service CIDR — then create a Service with an explicit ClusterIP inside that new range and verify DNS resolution.
