Answer: Configure Amazon Route 53 to point to API Gateway APIs in North America and Europe using latency-based routing and health checks. Configure the APIs to forward requests to a Lambda function in that Region. Configure the Lambda functions to retrieve and update the data in a DynamoDB global table.
The correct answer is B. The requirement is to ensure both high reliability and fast response times for users located in North America and Europe. To achieve this, Amazon Route 53 should be configured with latency-based routing to direct users to the nearest API Gateway endpoint, ensuring low latency. Additionally, health checks can be used to monitor the availability of each endpoint. By using DynamoDB global tables, data can be replicated across multiple regions, providing low-latency access and higher reliability. The Lambda functions in each region can then retrieve and update the data in these global tables, maintaining consistency and performance.

A company aims to implement a well-architected design for its globally accessible API stack, ensuring high reliability and fast response times for users in North America and Europe. The API stack includes Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. Which configuration will effectively meet these performance and reliability requirements?
A
Configure Amazon Route 53 to point to API Gateway APIs in North America and Europe using health checks. Configure the APIs to forward requests to a Lambda function in that Region. Configure the Lambda functions to retrieve and update the data in a DynamoDB table in the same Region as the Lambda function.
B
Configure Amazon Route 53 to point to API Gateway APIs in North America and Europe using latency-based routing and health checks. Configure the APIs to forward requests to a Lambda function in that Region. Configure the Lambda functions to retrieve and update the data in a DynamoDB global table.
C
Configure Amazon Route 53 to point to API Gateway in North America, create a disaster recovery API in Europe, and configure both APIs to forward requests to the Lambda functions in that Region. Retrieve the data from a DynamoDB global table. Deploy a Lambda function to check the North America API health every 5 minutes. In the event of a failure, update Route 53 to point to the disaster recovery API.
D
Configure Amazon Route 53 to point to API Gateway API in North America using latency-based routing. Configure the API to forward requests to the Lambda function in the Region nearest to the user. Configure the Lambda function to retrieve and update the data in a DynamoDB table.
