A company is building an electronic document management system in which users upload their documents. The application stack is entirely serverless and runs on AWS in the eu-central-1 Region. The system includes a web application that uses an Amazon CloudFront distribution for delivery with Amazon S3 as the origin. The web application communicates with Amazon API Gateway Regional endpoints. The API Gateway APIs call AWS Lambda functions that store metadata in an Amazon Aurora Serverless database and put the documents into an S3 bucket. The company is growing steadily and has completed a proof of concept with its largest customer. The company must improve latency outside of Europe. Which combination of actions will meet these requirements? (Choose two.)
- AEnable S3 Transfer Acceleration on the S3 bucket. Ensure that the web application uses the Transfer Acceleration signed URLs. (correct answer)
- BCreate an accelerator in AWS Global Accelerator. Attach the accelerator to the CloudFront distribution.
- CChange the API Gateway Regional endpoints to edge-optimized endpoints. (correct answer)
- DProvision the entire stack in two other locations that are spread across the world. Use global databases on the Aurora Serverless cluster.
- EAdd an Amazon RDS proxy between the Lambda functions and the Aurora Serverless database.

The correct answer is A, C. Option A: Enable S3 Transfer Acceleration on the S3 bucket. Ensure that the web application uses the Transfer Acceleration signed URLs. Option C: Change the API Gateway Regional endpoints to edge-optimized endpoints.
Explanation
S3 Transfer Acceleration speeds up long-distance uploads to S3 over the AWS edge network. Amazon S3 provides durable, scalable object storage that is fully managed. Amazon API Gateway is a fully managed front door for creating and securing APIs at scale.
