You can monitor AWS resources in multiple regions using a single CloudWatch dashboard.
For more information on the Cloudwatch dashboard, please refer to the below URL.
http://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/cross_region_dashboard.htmlOption B is the correct answer.
Amazon CloudWatch is a monitoring and observability service provided by AWS that allows you to monitor AWS resources and the applications running on them. CloudWatch can collect and track metrics, collect and monitor log files, and set alarms.
To monitor the performance of EC2 instances in different regions using CloudWatch, you can register instances running in different regions to CloudWatch using the CloudWatch agent. The CloudWatch agent can be installed on your EC2 instances and can collect system-level metrics and log files from your instances.
Once you have registered your instances, you can use CloudWatch to view metrics and create alarms that track changes in metrics over time. You can also create dashboards to view metrics from multiple instances and regions on a single page.
Option A is not the best approach because it would require creating separate dashboards in every region, which could be time-consuming and difficult to manage. Option C is a better approach because it allows you to view metrics from multiple instances and regions on a single page, but it is not the best answer because it assumes that you can report metrics from different regions to a single dashboard without registering the instances to CloudWatch.
Option D is incorrect because CloudWatch can monitor resources across different regions and services, including EC2 instances.
