AWS Certified DevOps Engineer – Professional — Question 203

A company uses a series of individual Amazon CloudFormation templates to deploy its multi-Region applications. These templates must be deployed in a specific order. The company is making more changes to the templates than previously expected and wants to deploy new templates more efficiently. Additionally, the data engineering team must be notified of all changes to the templates.
What should the company do to accomplish these goals?

Answer options

• A. Create an AWS Lambda function to deploy the CloudFormation templates in the required order. Use stack policies to alert the data engineering team.
• B. Host the CloudFormation templates in Amazon S3. Use Amazon S3 events to directly trigger CloudFormation updates and Amazon SNS notifications.
• C. Implement CloudFormation StackSets and use drift detection to trigger update alerts to the data engineering team.
• D. Leverage CloudFormation nested stacks and stack sets for deployments. Use Amazon SNS to notify the data engineering team.

Correct answer: D

Explanation

The correct answer, D, is appropriate because it allows for organized deployment of CloudFormation templates using nested stacks and stack sets, while also facilitating notifications through Amazon SNS. Option A lacks the efficiency of nested stacks, option B doesn't ensure the required order of deployments, and option C, while useful, doesn't incorporate the ease of notifications as effectively as option D.
