A globally accessible API stack consists of API Gateway -> Lambda -> DynamoDB. The company requires both high reliability and low latency for users in North America and Europe. Which architecture meets these goals?

The correct option provides both high reliability and low latency. Route 53 with latency-based routing directs users to the closest healthy API Gateway endpoint, ensuring low latency. Deploying API Gateway and Lambda in both North America and Europe allows processing to occur geographically closer to users. DynamoDB global tables automatically replicate data across specified Regions, providing high availability and low-latency data access from any configured Region. The first incorrect option uses DynamoDB tables in the same Region as the Lambda, which means data is not replicated globally, impacting reliability and latency for users accessing data from a different Region if the primary Region fails or is distant. The third incorrect option uses a disaster recovery setup rather than an active-active, low-latency architecture. The manual health check and failover process is slow and doesn't provide continuous low latency. The fourth incorrect option uses a single DynamoDB table, which would introduce high latency for users not in the table's Region and presents a single point of failure.
