A company recently migrated its three-tier web application to AWS.The application runs on Amazon EC2 instances that are in an Auto Scaling group.A SysOps administrator must create a monitoring dashboard to watch CPU and network utilization for each instance at 1-minute intervals.
How can the SysOps administrator meet this requirement?
Create an Amazon CloudWatch dashboard with basic monitoring.
Set up AWS CloudTrail with a dashboard on Amazon QuickSight.
Create an Amazon CloudWatch dashboard, and enable detailed monitoring.
Use the AWS Personal Health Dashboard.
Explanations:
Basic monitoring provides data at 5-minute intervals, not 1-minute intervals.
AWS CloudTrail records API activity and isn’t used for performance metrics like CPU and network utilization.
Enabling detailed monitoring in CloudWatch provides data at 1-minute intervals, which meets the requirement.
The AWS Personal Health Dashboard provides information about AWS service events, not instance performance metrics.
