Which solution will meet these requirements?
Create five Amazon CloudWatch alarms, one for each Trusted Advisor service quota metric. Configure an Amazon Simple Notification Service (Amazon SNS) topic for email notification each time that usage exceeds 60% of one of the service quotas.
Create five Amazon CloudWatch alarms, one for each Trusted Advisor service quota metric. Configure an Amazon Simple Queue Service (Amazon SQS) queue for email notification each time that usage exceeds 60% of one of the service quotas.
Use the AWS Service Health Dashboard to monitor each Trusted Advisor service quota metric. Configure an Amazon Simple Queue Service (Amazon SQS) queue for email notification each time that usage exceeds 60% of one of the service quotas.
Use the AWS Service Health Dashboard to monitor each Trusted Advisor service quota metric. Configure an Amazon Simple Notification Service (Amazon SNS) topic for email notification each time that usage exceeds 60% of one of the service quotas.
Explanations:
CloudWatch alarms can monitor Trusted Advisor service quota metrics and trigger notifications via Amazon SNS. SNS supports email notifications, which satisfies the requirement of receiving email notifications when usage exceeds 60%.
Although CloudWatch alarms can monitor Trusted Advisor service quota metrics, Amazon SQS is not suitable for email notifications. SQS is used for queuing messages, not sending emails.
The AWS Service Health Dashboard is used for monitoring service status, not specific Trusted Advisor metrics. Therefore, it cannot track service quota metrics to trigger notifications.
The AWS Service Health Dashboard is not designed for monitoring specific Trusted Advisor metrics. It only shows service health and is not suitable for tracking quotas or triggering email notifications.
I categorize that the answer is:
Create five Amazon CloudWatch alarms, one for each Trusted Advisor service quota metric. Configure an Amazon Simple Notification Service (Amazon SNS) topic for email notification each time that usage exceeds 60% of one of the service quotas.
