Exam AWS Certified DevOps Engineer - Professional DOP-C02 topic 1 question 111 discussion

The answer is D because: A few hours ago, I just finished the DOP-C02 exam. My score is 1000 points. This question has come up, I choose D.

Here's why this solution is the best approach: Nested Stacks: CloudFormation nested stacks allow you to break down complex templates into smaller, more manageable templates. You can create a root stack that references and manages multiple nested stacks. This approach simplifies the management and deployment of multiple interdependent templates in the correct order. StackSets: CloudFormation StackSets allow you to create, update, or delete stacks across multiple AWS accounts and regions with a single operation. This addresses the requirement of deploying applications across multiple regions efficiently. Amazon SNS: Amazon Simple Notification Service (SNS) can be used to send notifications to the data engineering team whenever changes are made to the CloudFormation templates or stacks.

should be D

Answer is D.

the nested for order : https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-nested-stacks.html

D is correct: <uses a series of individual Amazon CloudFormation templates to deploy its multi-Region applications> and <wants to deploy new templates more efficiently> mean stacksets, which is template for multiple regions. <the data engineering team must be notified of all changes> means SNS A and B: no mention of stacksets C: no mention of SNS

D is the answer

It's D. C is not correct since according to this link: https://aws.amazon.com/blogs/mt/implementing-an-alarm-to-automatically-detect-drift-in-aws-cloudformation-stacks/ We need AWS config rule to detect drifts and to send event. There is no build in solution to notify drift detection like mentioned in C,

C is for notifying changes on what has been deployed by Cloud Formation D is for notifying changes made on the Cloud Formation template (the recipe) itself

C didn't mention how to deploy in a specific order. D mentioned nested stack, which you can configure the dependency ordering

I got D as my answer

D is correct

it' s D, I think.

D is correct.

The correct solution is D: The solution works as follows: AWS Config triggers the evaluation when any resource that matches the rule’s scope (currently set to “AWS::CloudFormation::Stack”) changes in configuration and at the frequency (“MaximumExecutionFrequency” parameter) that you specify at the time of this solution deployment. EventBridge receives the events from AWS Config, applies the EventBridge rule to match the compliance change event, and transforms the input (customize the text) as defined in the “InputTransformer” template. The chosen customer-managed KMS Key is then accessed to encrypt the notification. The encrypted notification is published to the target SNS topic. The endpoints subscribed to this topic start receiving the published messages.
