A company has developed an API using Amazon API Gateway REST API and AWS Lambda. How can latency be reduced for users worldwide?

The correct answer is A. Deploy the REST API as an edge-optimized API endpoint. Enable caching. Enable content. Edge-optimized API endpointsroute requests through CloudFront, reducing latency for global Option A correctly implements edge-optimization, caching, and compression to minimize latency. Options B and D do not use edge optimization, leading to higher latency for global users…

Explanation

Edge-optimized API endpointsroute requests through CloudFront, reducing latency for global Option A correctly implements edge-optimization, caching, and compression to minimize latency. Options B and D do not use edge optimization, leading to higher latency for global users. Reserved concurrency in Options C and D improves backend scaling but does not address global latency directly.
