You are an AWS administrator. Last week, a new employee accidentally deleted a repository branch in CodeCommit. For certain key repositories, you are told to create a notification when someone deletes any branch in CodeCommit. You plan to configure a trigger in CodeCommit. Which service should you use to implement this in the best way?

Answer options:

A.In CodeCommit, create a trigger to a Lambda function that works with AWS Simple Email Service to send emails to notify users when a branch is deleted.
B.In CodeCommit, create a trigger for branch deletion event to an Amazon SQS queue to provide warnings to users.
C.For the repository event of deleting branches, create a trigger in CodeCommit to an Amazon SNS topic to provide notifications to users.
D.For the repository event of deleting branches, create a trigger in CodeCommit to an AWS CloudWatch Event to provide warnings.

Correct Answer – C
For a CodeCommit repository, you can configure triggers so that code pushes or other events can trigger actions. The supported trigger services are SNS and Lambda. You can create up to 10 triggers for each CodeCommit repository:
Option A is incorrect: Although the Lambda function potentially works, it brings unnecessary work to interact with SES. For this case, the best way is to use SNS.
Option B is incorrect: Because the CodeCommit trigger service does not support SQS.
Option C is CORRECT: Because SNS is the easiest and straightforward method. Users need to subscribe to the SNS topic and get notified.
Option D is incorrect: Same reason as Option
B.
