How can the developer meet these requirements?
Publish a custom metric to Amazon CloudWatch. Create a metric alarm. Use Amazon Simple Email Service (Amazon SES) for notification.
Use an Amazon CloudWatch API error metric. Use Amazon Simple Notification Service (Amazon SNS) for notification.
Use an Amazon CloudWatch API error metric. Use Amazon Simple Email Service (Amazon SES) for notification.
Publish a custom metric to Amazon CloudWatch. Create a metric alarm. Use Amazon Simple Notification Service (Amazon SNS) for notification.
Explanations:
While this option suggests publishing a custom metric and creating a metric alarm, it incorrectly specifies using Amazon SES for notifications. SES is primarily for sending emails and is not designed for alerting or notifying about CloudWatch alarms.
This option uses an Amazon CloudWatch API error metric, which is valid, but it incorrectly suggests using Amazon SNS for notifications without specifying any custom metrics or alarms needed to monitor the specific API errors.
Similar to option B, this option uses the Amazon CloudWatch API error metric correctly, but it incorrectly indicates using Amazon SES for notifications. SES does not provide a mechanism to automatically alert based on CloudWatch metrics.
This option correctly proposes publishing a custom metric to Amazon CloudWatch, creating a metric alarm, and using Amazon SNS for notifications. SNS is suitable for sending alerts based on CloudWatch alarm states, making it the correct choice for this scenario.
I plan that the answer is:
Publish a custom metric to Amazon CloudWatch. Create a metric alarm. Use Amazon Simple Notification Service (Amazon SNS) for notification.
