AWS Certified SysOps Administrator – Associate — Question 291

A company has an encrypted Amazon S3 bucket that is hosted in the ap-southeast-2 Region. Users from the eu-west-2 Region access the S3 bucket over the internet. The users from eu-west-2 need faster transfers to and from the S3 bucket for large files.

Which solution will meet these requirements?

Answer options

• A. Reduce the length of the S3 bucket prefixes within the S3 bucket.
• B. Change the server-side encryption on the S3 bucket from AES to RSA.
• C. Create a new S3 bucket that has an identical name in eu-west-2. Use the new S3 bucket endpoint's domain name for access.
• D. Enable S3 Transfer Acceleration on the S3 bucket. Use the new s3-accelerate endpoint's domain name for access.

Correct answer: D

Explanation

Amazon S3 Transfer Acceleration utilizes CloudFront's globally distributed Edge Locations and the AWS backbone network to minimize latency for long-distance data transfers. Changing encryption algorithms or prefix lengths does not resolve network transit bottlenecks. Additionally, S3 bucket names must be globally unique, making it impossible to create an identical-named bucket in another region.
