Configure DNS and Routing Policies with Amazon Route 53

Why it matters

DNS configuration and resource health are part of the networking foundation for GenAI API availability. This exercise gives you practice with Route 53 records and health checks.

What to practise

Create a private hosted zone, configure records for private and public endpoints, and verify web server accessibility with network and DNS troubleshooting tools. Compare health check approaches for private and public resources. Configure simple routing with health checks and observe the accessibility test results.

How it fits

For 1.2.10, focus on the private and public health checks that regional GenAI API recovery depends on. The exercise pairs them with simple routing; the failover routing policy that 1.2.10 chooses is not among its objectives.
