A developer built a serverless application that processes medical images. The images are often more than 1 GB in size. Users upload all the images directly to an Amazon S3 bucket for processing. The application has users throughout the

world, and most users are geographically far away from the AWS Region that runs the application.

Users are experiencing long wait times when they upload large images. The developer must create a solution to minimize the latency that users experience when they upload images to Amazon S3.

Which solution will produce the HIGHEST throughput?

A. Configure S3 Transfer Acceleration on the S3 bucket

B. Configure an Amazon CloudFront distribution with the S3 endpoint as the origin

C. Configure Amazon ElastiCache on the S3 bucket

D. Configure AWS Global Accelerator on the S3 bucket
