AWS Certified Solutions Architect Professional SAP-C02 Practice Question

The correct answer is to enable S3 Transfer Acceleration on the S3 bucket. This feature is specifically designed to speed up long-distance file transfers to and from Amazon S3. It works by routing uploads through Amazon CloudFront's globally distributed edge locations, which then transfer the data to the S3 bucket over an optimized network path. This solution is ideal for use cases where users are geographically dispersed and need to upload large files to a centralized bucket. It requires minimal client-side changes, as users only need to target a different endpoint (.s3-accelerate.amazonaws.com).

Using multipart upload is a recommended practice for large files as it can improve throughput via parallelization and increase resilience to network errors. However, it does not by itself solve the core problem of network latency over long distances across the public internet. It is a complementary technique that can be used with S3 Transfer Acceleration for optimal performance.

Establishing an AWS Direct Connect connection is incorrect because it provides a dedicated network link from a fixed location, such as a corporate office, to AWS. It would not benefit the freelance journalists who are uploading from various remote locations across the globe.

Using AWS Global Accelerator is an overly complex and costly solution for this specific problem. While Global Accelerator improves application performance using the AWS global network, it is designed for application endpoints like Load Balancers and EC2 instances, not directly for S3 uploads. S3 Transfer Acceleration is the purpose-built, simpler, and more cost-effective solution for accelerating S3 transfers.
