Topic 1 Question 302
A team of developers is using several Amazon S3 buckets as centralized repositories. Users across the world upload large sets of files to these repositories. The development team's applications later process these files.
A SysOps administrator sets up a new S3 bucket, DOC-EXAMPLE-BUCKET, to support a new workload, The rew S3 bucket also receives regular uploads cf large sets of files from users worldwide. When the new S3 bucket is put into production, the upload performance from certain geographic areas is lower than the upload performance that the existing $3 buckets provide
What should the SysOps administrator do to remediate this issue?
Provision an Amazon ElastiCache for Redis cluster for the new S3 bucket. Provide the developers with the configuration endpoint of the cluster for use in their API calls
Add the new S3 bucket to a new Amazon CloudFront distribution. Provide the developers with the domain name of the new distribution for use in their API calls.
Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.
Use S3 multipart upload for the new S3 bucket. Verify that the developers are using Region-specific S3 endpoint names such as DOC-EXAMPLE-BUCKETS3, [Region] amazonaws.com in their API calls.

After researching this realize that the "s3-accelerate" domain in the special URL (e.g.: "acloudguru.s3-accelerate.amazonaws.com") will resolve to the nearest edge globally, and therefore there is only one url that can be used globally to make use of transfer acceleration, albeit at some additional cost for the data transfer. Setting must be enabled on bucket though. The URLs are worth reviewing (at least they were to me) https://docs.aws.amazon.com/AmazonS3/latest/userguide/transfer-acceleration-examples.html https://www.javatpoint.com/aws-s3-transfer-acceleration etc.

multipart upload ,not a solution for global performance issues,so D is out
