Question
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 new 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?
A. 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
B. 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.
C. 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.
D. 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.
Answer
C. 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.
Explanation
The correct answer is C. 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.
Amazon S3 is a service that provides scalable, durable, and secure object storage. You can use S3 to store and retrieve any amount of data from anywhere on the web. You can also use S3 to host static websites, serve media files, or store backups.
S3 Transfer Acceleration is a feature that enables you to speed up the upload of large sets of files to S3 buckets from users across the world. S3 Transfer Acceleration leverages the AWS global network and edge locations to route your upload requests to the nearest S3 endpoint, which can reduce the latency and improve the throughput of your uploads.
To use S3 Transfer Acceleration, you need to enable it for your S3 bucket from the S3 console, AWS CLI, or AWS SDKs. You also need to use a different endpoint name for your API calls, which has the format bucketname.s3-accelerate.amazonaws.com. For example, if your bucket name is DOC-EXAMPLE-BUCKET, you need to use DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com as the endpoint name for your uploads.
By using this solution, you can remediate the issue of low upload performance from certain geographic areas for your new S3 bucket. This solution meets the requirements of the company, as it allows them to provision their EC2 instances by using only approved EC2 instance configurations. This solution is also the most operationally efficient one, as it does not require them to use any additional services or tools. It also leverages the existing functionality and scalability of S3 and S3 Transfer Acceleration.
The other options are not correct for the following reasons:
A. 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.
This option is not correct, as ElastiCache for Redis is a service that provides in-memory data store and caching for your applications. It does not provide any functionality or benefit for uploading files to S3 buckets.
B. 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.
This option is not correct, as CloudFront is a service that provides content delivery network (CDN) for your web applications. It can help you improve the performance and availability of your web content by caching it at edge locations near your users. However, CloudFront does not provide any functionality or benefit for uploading files to S3 buckets.
D. 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.
This option is not correct, as S3 multipart upload is a feature that enables you to upload large files to S3 buckets in multiple parts concurrently. It can help you improve the performance and reliability of your uploads by allowing you to resume or retry failed parts without affecting the rest of the upload. However, S3 multipart upload does not provide any functionality or benefit for uploading files from different geographic areas to S3 buckets.
