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. What should the SysOps administrator do to remediate this issue?

Answers
E.
Create an Amazon CloudWatch dashboard that shows the Sum statistic of the ProcessedBytes metric for the ALB.
Suggested answer: A, C

Explanation:

Enable Access Logging for the ALB:

Access logging provides detailed information about requests sent to your load balancer.

Steps:

Go to the AWS Management Console.

Navigate to EC2 and select 'Load Balancers.'

Select your Application Load Balancer.

Under the 'Attributes' tab, enable 'Access logs.'

Specify an S3 bucket where the logs will be saved.

Use Amazon Athena to Query the ALB Logs:

Athena allows you to run SQL queries on data stored in S3.

Steps:

Go to the AWS Management Console.

Navigate to Athena.

Create a table for the ALB logs using the appropriate schema.

Run queries to calculate the total bytes sent and received, grouped by the target field.

Example query:

SELECT target, SUM(received_bytes) as total_received, SUM(sent_bytes) as total_sent

FROM alb_logs

GROUP BY target, port
