AWS Certified DevOps Engineer – Professional (DOP-C02) — Question 86

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 is D because using CloudFormation nested stacks and stack sets allows for organized deployments in the specified order while efficiently managing resources across multiple regions. This approach also enables the use of Amazon SNS for sending notifications, ensuring the data engineering team is promptly informed of any changes. The other options either do not efficiently manage the deployment order or lack a robust notification mechanism.
