AWS Certified Cloud Practitioner — Question 409

A company with many remote global locations needs to upload 100 GB of data daily to its Amazon S3 data lake. The remote locations experience high latency uploading data and need to find a solution to improve performance.

Which AWS service or feature will meet these requirements?

Answer options

• A. AWS Snowball
• B. AWS Storage Gateway
• C. AWS Database Migration Service (AWS DMS)
• D. S3 Transfer Acceleration

Correct answer: D

Explanation

Amazon S3 Transfer Acceleration is designed to speed up content uploads over long distances by routing traffic through Amazon CloudFront's globally distributed edge locations and over the optimized AWS backbone network. AWS Snowball is impractical for daily 100 GB uploads as it involves physical device shipping, while AWS Storage Gateway and AWS DMS are intended for hybrid storage integration and database migrations rather than optimizing WAN transfer speeds to S3.
