An operations team wants one dashboard that shows metrics for workloads in us-east-1, eu-west-1, and ap-southeast-2. Is that possible with CloudWatch dashboards?
Show answer and explanation
Answer: A
A CloudWatch dashboard is a global view object, and each widget can target metrics in any Region by specifying the Region in the widget definition. That makes a single cross-Region operations board practical.
The dashboard itself must be created in a home Region, and the viewer needs permissions in every Region whose metrics are shown.
Why the other options are wrong
- B. Region selection happens per widget, so a board is not confined to its creation Region.
- C. Lambda is not involved; widgets pull metrics directly from the metric stores in each Region.
- D. CloudFormation can define dashboards, but it is not a prerequisite for cross-Region widgets.
Exam tip. One dashboard, many Regions: set the Region per widget.
