SOA-C02 Question 330
Select 2You are managing a global application that uploads large media files to an Amazon S3 bucket. Users from various regions have reported slow upload speeds. Additionally, the uploaded files are often large, and you want to optimize network performance and ensure efficient uploads. Which combination of S3 features should you implement to address these issues?
- A
Enable S3 Transfer Acceleration on the bucket
- B
Use multipart uploads for large files
- C
Configure S3 Lifecycle policies to optimize uploads
- D
Enable bucket versioning to improve upload speed
- E
Use pre-signed URLs to provide secure upload access to users
Show answer and explanation
Correct answers: A, B
Explanation
To optimize upload performance for global users and large files, enabling S3 Transfer Acceleration and using multipart uploads are recommended. Transfer Acceleration leverages CloudFront for faster data transfers over long distances, while multipart uploads allow large files to be uploaded in smaller parts that can be uploaded in parallel, improving efficiency and reliability.
- A. Correct.
Correct. S3 Transfer Acceleration uses CloudFront’s globally distributed edge locations to accelerate uploads, especially for users far from the S3 bucket’s region.
- B. Correct.
Correct. Multipart uploads divide large files into smaller parts, allowing parallel uploads and improving performance for large file transfers.
- C. Incorrect.
Incorrect. S3 Lifecycle policies are used to manage data lifecycle (e.g., transitions to storage classes or expiration), not to optimize upload speed or performance.
- D. Incorrect.
Incorrect. Bucket versioning is used for data protection and recovery, and does not have any impact on upload speed or performance.
- E. Incorrect.
Incorrect. While pre-signed URLs are useful for secure access, they do not inherently improve upload speed or performance for global users.
