Which solution will meet these requirements?
Reduce the length of the S3 bucket prefixes within the S3 bucket.
Change the server-side encryption on the S3 bucket from AES to RSA.
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.
Enable S3 Transfer Acceleration on the S3 bucket. Use the new s3-accelerate endpoint’s domain name for access.
Explanations:
Reducing the length of S3 bucket prefixes does not impact transfer speeds. The prefix length primarily affects the performance of S3 operations that involve listing objects, not the speed of data transfers over the internet.
Changing the server-side encryption from AES to RSA does not improve transfer speeds. Both encryption methods serve different purposes, and the choice of encryption should be based on security requirements rather than performance.
Creating a new S3 bucket in the eu-west-2 region with an identical name does not directly improve transfer speeds. Users would still need to manage data synchronization between the two buckets, and this could introduce additional complexity without guaranteed speed improvements.
Enabling S3 Transfer Acceleration allows for faster transfers by routing data through Amazon CloudFront’s globally distributed edge locations. This solution specifically targets performance improvements for large file transfers over the internet. Users should use the new s3-accelerate endpoint to take advantage of this feature.
If I had to guess, I’d say the answer is:
Enable S3 Transfer Acceleration on the S3 bucket. Use the new s3-accelerate endpoint’s domain name for access.
