AWS Certified SysOps Administrator – Associate — Question 13

A SysOps administrator must create a solution that immediately notifies software developers if an AWS Lambda function experiences an error.
Which solution will meet this requirement?

Answer options

• A. Create an Amazon Simple Notification Service (Amazon SNS) topic with an email subscription for each developer. Create an Amazon CloudWatch alarm by using the Errors metric and the Lambda function name as a dimension. Configure the alarm to send a notification to the SNS topic when the alarm state reaches ALARM.
• B. Create an Amazon Simple Notification Service (Amazon SNS) topic with a mobile subscription for each developer. Create an Amazon EventBridge (Amazon CloudWatch Events) alarm by using the LambdaError as the event pattern and the SNS topic name as a resource. Configure the alarm to send a notification to the SNS topic when the alarm state reaches ALARM.
• C. Verify each developer email address in Amazon Simple Email Service (Amazon SES). Create an Amazon CloudWatch rule by using the LambdaError metric and developer email addresses as dimensions. Configure the rule to send an email through Amazon SES when the rule state reaches ALARM.
• D. Verify each developer mobile phone in Amazon Simple Email Service (Amazon SES). Create an Amazon EventBridge (Amazon CloudWatch Events) rule by using Error as the event pattern and the Lambda function name as a resource. Configure the rule to send a push notification through Amazon SES when the rule state reaches ALARM.

Correct answer: A

Explanation

Option A is correct because it uses Amazon SNS to notify developers via email when a CloudWatch alarm, based on the Errors metric, triggers. The other options either use incorrect notification methods (such as mobile subscriptions or SES for emails) or do not properly trigger notifications based on Lambda function errors.
