SOA-C02 Question 332
Select 2A company is uploading a large dataset to an Amazon S3 bucket from locations around the globe. The team has noticed that the upload speed varies significantly depending on the users' location. They also want to ensure that the upload process is optimized for large objects. Which combination of S3 features should they use to address these challenges?
- A
Enable S3 Transfer Acceleration for the bucket
- B
Use multipart uploads for large objects
- C
Configure S3 Intelligent-Tiering storage class
- D
Enable versioning on the S3 bucket
- E
Use S3 Cross-Region Replication to improve upload speed
Show answer and explanation
Correct answers: A, B
Explanation
The combination of S3 Transfer Acceleration and multipart uploads addresses the company’s challenges. S3 Transfer Acceleration improves the upload speed for global users by routing traffic through AWS edge locations, while multipart uploads optimize the process for large objects by breaking them into smaller, parallel-uploaded parts. Other options, such as S3 Intelligent-Tiering, versioning, and cross-region replication, do not directly address upload speed or efficiency for large datasets.
- A. Correct.
Enabling S3 Transfer Acceleration allows data to be uploaded to S3 more quickly from geographically dispersed locations by leveraging AWS edge locations and the AWS global network, addressing the issue of varying upload speeds.
- B. Correct.
Multipart uploads help improve upload performance and reliability for large objects by breaking them into smaller parts, which can be uploaded in parallel, thus optimizing the upload process for large datasets.
- C. Incorrect.
S3 Intelligent-Tiering is a storage class that optimizes cost by automatically moving data between access tiers, but it does not improve upload performance or address varying upload speeds.
- D. Incorrect.
Enabling versioning on an S3 bucket adds the ability to preserve, retrieve, and restore every version of every object, but it does not help with improving upload speed or optimizing large uploads.
- E. Incorrect.
S3 Cross-Region Replication copies objects between buckets in different regions for redundancy and disaster recovery, but it does not improve upload speeds or optimize uploads from global locations.
