Explanation:
Amazon S3 automatically scales to support very high request rates. To maximize performance and throughput (especially when dealing with a massive number of files or high transaction rates), it is a best practice to parallelize operations across multiple prefixes. Each prefix in an S3 bucket can support up to 3,500 PUT/COPY/POST/DELETE requests per second. By splitting the write operations across multiple bucket prefixes, the application can achieve much higher overall throughput. S3 Transfer Acceleration is designed to optimize transfers over the public internet over long distances, not for an EC2 instance uploading to an S3 bucket in the same Region.

Question 23
A company is running a development application on an Amazon EC2 instance. The application uploads 500,000 files that are 1 GB in size into a target Amazon S3 bucket that has default encryption enabled. The EC2 instance is in the same AWS Region where the S3 bucket is deployed.
The company uses performance logging that is built into the application software. The logs show that the application is constantly waiting for the files to be written to the S3 bucket. A SysOps administrator needs to improve the application's throughput performance. The SysOps administrator validates that the networking on the EC2 instance is not constrained.
What should the SysOps administrator do to improve the S3 upload performance?
A
Enable S3 Transfer Acceleration on the S3 bucket.
B
Split the S3 write operations to use multiple bucket prefixes to write items in parallel.
C
Configure AWS PrivateLink for Amazon S3. Turn off encryption on the S3 bucket.
D
Configure AWS Global Accelerator in the Region. Turn off encryption on the S3 bucket.
