Which solution will meet these requirements?
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 of 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 S3 buckets provide.

Suggested answer: A

Explanation:

Amazon CloudWatch Synthetics:

CloudWatch Synthetics allows you to create canaries to monitor your endpoints and API calls, simulating user behavior to detect issues before users do.

Steps:

Go to the AWS Management Console.

Navigate to CloudWatch and select 'Synthetics.'

Click on 'Create canary.'

Choose 'Heartbeat monitoring' as the blueprint.

Configure the canary to point to the FQDN of the website.

Set the frequency and retention settings as per your requirement.

Create the canary.

This setup continuously checks the operational status of your website, alerting you if it becomes unreachable or has issues.
