Module 1 · Recall check

1. A Deployment's `selector.matchLabels` doesn't match any of its Pod template's labels. What happens?

2. You scale a Deployment from 2 replicas to 5. Where does Kubernetes record that new desired state?

3. Why use a `Service` in front of a set of Pods instead of hitting Pod IPs directly?

4. In your `kind-config.yaml` you set `hostPort: 9898` mapping to `containerPort: 30080`. Why did that specific number (30080) need to match the Service?

5. Which command gives the quickest read on WHY a Pod is stuck in `Pending`?
