An organization tracks five Trusted Advisor service quota metrics in a single AWS Region and wants to be emailed whenever any quota’s usage goes above 60%. What approach satisfies this requirement?

The correct approach is to create five Amazon CloudWatch alarms, one for each Trusted Advisor service quota metric. CloudWatch alarms can monitor specific metrics and trigger actions when a threshold is breached. In this case, each alarm would be configured to trigger when its respective quota's usage exceeds 60%. By attaching an Amazon SNS topic to these alarms, a single email notification can be sent to subscribers whenever any of the alarms enters an ALARM state. Incorrect options: Using Amazon SQS for email notifications is not a direct method. SQS is a message queuing service, not an email notification service. While SQS could be part of a more complex notification system, SNS is designed for direct fan-out notifications, including email. The AWS Service Health Dashboard provides general health information but does not offer direct, configurable alerting based on specific service quota usage thresholds. It's for broader service health, not granular metric-based alerting.
