AWS Certified SysOps Administrator – Associate (legacy) — Question 736

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?

Answer options

• A. Create an Amazon CloudWatch dashboard with basic monitoring.
• B. Set up AWS CloudTrail with a dashboard on Amazon QuickSight.
• C. Create an Amazon CloudWatch dashboard, and enable detailed monitoring.
• D. Use the AWS Personal Health Dashboard.

Correct answer: C

Explanation

By default, Amazon EC2 basic monitoring provides metrics at 5-minute intervals, whereas detailed monitoring is required to obtain metrics at 1-minute intervals. Therefore, creating an Amazon CloudWatch dashboard and enabling detailed monitoring fulfills the requirement for 1-minute tracking. AWS CloudTrail is for API logging, and the AWS Personal Health Dashboard tracks service health, making them incorrect for performance metric visualization.
