B is the correct solution. The requirement is to ensure both high reliability and fast response times for users located in North America and Europe. To meet this requirement, we can use Amazon Route 53 with latency-based routing to direct users to the closest API Gateway endpoint. Additionally, we can use health checks to monitor the health of each endpoint and direct traffic away from unhealthy endpoints. To maintain high reliability, we can use AWS Lambda to handle the API requests. Since Lambda scales automatically, we don't need to worry about provisioning or maintaining infrastructure. We can also use DynamoDB as the database since it provides low latency access and automatic scaling.

B is correct: using both latency-based routing and health checks ensures high reliability and fast response A: only health check doesnt ensure fast response C: All traffic would be routed to one location only (either NA or Europe if NA failed) D: All traffic would be routed to one NA only. There would be no entry point which is near Europe users.

B is correct

B , Using latency based routing for better response time . Having api gateway in each region reduce requrest fligh time. Lambda and Dynamo being a managed serivce scale automatically and having them in same region just reduce latency.

Reliability is different that resiliency, hence A and C are out as they are focussing on health checks which is required for the resiliency. DR again for the resiliency

B is the best solution.

B is correct
