A global financial company is designing a multi-region active-active architecture for their core trading platform. The platform uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. They need to route users to the region that provides the lowest latency. If a region fails, traffic must automatically failover to the healthy region. Which combination of Route 53 configurations should be used? (Select TWO)

Answer options:

Configure a Geolocation routing policy.

Configure a Latency routing policy.

Associate Route 53 Health Checks with the DNS records.

Configure a Failover routing policy.

Use AWS Global Accelerator instead of Route 53.

Configure a Multivalue Answer routing policy.

How to approach this question

Combine Latency routing (for performance) with Health Checks (for failover).

Full Answer

Configure a Latency routing policy. Associate Route 53 Health Checks with the DNS records.

For an active-active architecture optimized for performance, a Latency routing policy ensures users hit the fastest region. Attaching Route 53 Health Checks to these records ensures that if a region goes down, Route 53 automatically routes traffic to the remaining healthy regions.

Common mistakes

Choosing Failover routing, which is strictly for active-passive setups.
