Exam AWS Certified SysOps Administrator - Associate topic 1 question 473 discussion

+ The EC2 instance is in the same AWS Region where the S3 bucket is deployed. another option where S3 Tr Acc will be useless, so B is correct

Yeap Igor is right, it's B. Amazon S3 performance is optimized for high throughput, but one way to ensure maximum performance when writing large numbers of files is to structure the write requests to leverage parallelism. S3's architecture supports high request rates by using a combination of bucket and object naming strategies. By using multiple prefixes, the application can make concurrent upload requests, which can help improve throughput performance.This feature is designed to speed up transfers over long distances between the client and the S3 bucket. Since the EC2 instance and the S3 bucket are in the same AWS Region, enabling Transfer Acceleration wouldn't significantly improve the performance, as it is primarily for improving transfer speeds across long geographic distances.

Read the question again that makes me thing that the issue may not be resolved from network side via S3 Transfer Acceleration option since it clearly states this: "The SysOps administrator validates that the networking on the EC2 instance is not constrained." That makes me think now to go with option B as the issue is stemming up with the application's throughput level which can be resolved by using multiple prefixes for the write operations in the S3 bucket.
