AWS Certified SysOps Administrator – Associate (legacy) — Question 171

A SysOps Administrator is running Amazon EC2 instances in multiple AWS Regions. The Administrator wants to aggregate the CPU utilization for all instances onto an Amazon CloudWatch dashboard. Each region should be present on the dashboard and represented by a single graph that contains the CPU utilization for all instances in that region.
How can the Administrator meet these requirements?

Answer options

• A. Create a cross-region dashboard using AWS Lambda and distribute it to all regions
• B. Create a custom CloudWatch dashboard and add a widget for each region in the AWS Management Console
• C. Enable cross-region dashboards under the CloudWatch section of the AWS Management Console
• D. Switch from basic monitoring to detailed monitoring on all instances

Correct answer: B

Explanation

The correct answer is B because creating a custom CloudWatch dashboard allows the Administrator to add specific widgets for each region’s CPU utilization. Options A and C do not provide a direct way to represent each region's data on a single graph, while D only changes the monitoring granularity and does not address the dashboard requirement.
