A company uses Amazon S3 to aggregate raw video footage from various media teams across the US. The company recently expanded into new geographies in Europe and Australia. The technical teams located in Europe and Australia reported delays when uploading large video files into the destination S3 bucket in the United States. What are the MOST cost-effective ways to increase upload speeds into the S3 bucket? (Choose two.)

• A. Create multiple AWS Direct Connect connections between AWS and branch offices in Europe and Australia for file uploads into the destination S3 bucket.

• C. Use Amazon S3 Transfer Acceleration for file uploads into the destination S3 bucket. ✓
• D. Use AWS Global Accelerator for file uploads into the destination S3 bucket from the branch offices in Europe and Australia.
• E. Use multipart uploads for file uploads into the destination S3 bucket from the branch offices in Europe and Australia. ✓

Correct Answer: C. Use Amazon S3 Transfer Acceleration for file uploads into the destination S3 bucket., E. Use multipart uploads for file uploads into the destination S3 bucket from the branch offices in Europe and Australia.

Explanation

Amazon S3 Transfer Acceleration 通过优化客户端到 S3 的网络路径，利用 CloudFront 边缘站点加速长距离传输（AWS文档）。S3多部分上传允许并行传输文件分块，提升吞吐量和恢复能力（AWS S3 开发指南）。选项 C 和 E 直接针对远距离、大文件场景优化，无需前期投资或复杂架构变更。A/B涉及专线或VPN成本较高；D针对应用层加速，不特定于S3传输协议。
