Explanation:
To track detailed request-level information such as the number of bytes sent to and received from each target group member, you must enable access logging on the Application Load Balancer and store the logs in an Amazon S3 bucket (Option A). Once logs are stored in S3, you can use Amazon Athena to query the logs, filter them, and aggregate the sent_bytes and received_bytes by the target IP/port (Option C) to generate the required report.

Question 47
A SysOps administrator needs to create a report that shows how many bytes are sent to and received from each target group member for an Application Load Balancer (ALB). Which combination of steps should the SysOps administrator take to meet these requirements? (Choose two.)
A
Enable access logging for the ALB. Save the logs to an Amazon S3 bucket.
B
Install the Amazon CloudWatch agent on the instances in the target group.
C
Use Amazon Athena to query the ALB logs. Query the table. Use the received_bytes and sent_bytes fields to calculate the total bytes grouped by the target port field.
D
Use Amazon Athena to query the ALB logs. Query the table. Use the received_bytes and sent_bytes fields to calculate the total bytes grouped by the client port field.
E
Create an Amazon CloudWatch dashboard that shows the Sum statistic of the ProcessedBytes metric for the ALB.
