AWS Certified SysOps Administrator – Associate (legacy) — Question 217

A user has launched 10 instances from the same AMI ID using Auto Scaling. The user is trying to see the average CPU utilization across all instances of the last 2 weeks under the CloudWatch console. How can the user achieve this?

Answer options

• A. View the Auto Scaling CPU metrics
• B. Aggregate the data over the instance AMI ID
• C. The user has to use the CloudWatchanalyser to find the average data across instances
• D. It is not possible to see the average CPU utilization of the same AMI ID since the instance ID is different

Correct answer: A

Explanation

The correct answer is A because Auto Scaling provides aggregated metrics for all instances under its management, allowing users to view the average CPU utilization. The other options are incorrect as they either suggest an invalid method or imply that the differences in instance IDs prevent aggregation, which is not the case in Auto Scaling.
