AWS Certified Cloud Practitioner — Question 553

A company needs to monitor compute usage and receive an email message notification every time an Amazon EC2 instance starts or stops.

Which AWS service should the company use to meet these requirements?

Answer options

• A. Amazon EventBridge
• B. Amazon WorkMail
• C. Amazon Simple Email Service (Amazon SES)
• D. AWS Trusted Advisor

Correct answer: A

Explanation

Amazon EventBridge can detect state changes in Amazon EC2 instances, such as starting or stopping, and route those events to targets like Amazon SNS to send email notifications. Amazon SES and Amazon WorkMail are email services but lack the native ability to monitor and trigger actions based on EC2 state changes. AWS Trusted Advisor is used for optimization recommendations rather than real-time event-driven monitoring.
