Check Impact of Changes in CloudFormation Stack Resources
Question
You are in charge of designing a number of Cloudformation templates for your organization.
You are required to make changes to the stack resources every now and then based on the requirement.

The AWS Documentation mentions.
When you need to update a stack, understanding how your changes will affect running resources before you implement them can help you update stacks with confidence.
Change sets allow you to preview how proposed changes to a stack might impact your running resources, for example, whether your changes will delete or replace any critical resources, AWS CloudFormation makes the changes to your stack only when you decide to execute the change set, allowing you to decide whether to proceed with your proposed changes or explore other changes by creating another change set.
You can create and manage change sets using the AWS CloudFormation console, AWS CLI, or AWS CloudFormation API.

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-changesets.htmlThe correct answer is B. Use Cloudformation change sets to check for the impact to the changes.
CloudFormation is a service provided by AWS that enables users to automate the creation and management of AWS resources. With CloudFormation, users can define templates that specify the resources they need, as well as any dependencies or other configuration details. Once a template is defined, CloudFormation can create and manage the resources automatically, using the AWS APIs.
When you make changes to a CloudFormation stack, it's important to understand the impact those changes will have on the stack resources. CloudFormation change sets can help with this process. A change set is a summary of the proposed changes to a stack, and it includes information about how those changes will impact the stack resources.
To use CloudFormation change sets, you first create a change set that describes the changes you want to make to the stack resources. This change set is created separately from the actual stack, so you can review the proposed changes before applying them. Once you have reviewed the change set, you can either execute it to make the changes or discard it if you decide not to proceed.
Here are the steps to create a change set in CloudFormation:
- Open the AWS Management Console and navigate to the CloudFormation dashboard.
- Select the stack you want to modify.
- Click the "Actions" button and select "Create Change Set."
- Follow the prompts to specify the changes you want to make.
- Review the change set to see how the changes will impact the stack resources.
- Decide whether to execute or discard the change set.
Using CloudFormation change sets can help you avoid making unexpected changes to your stack resources. By reviewing the proposed changes before applying them, you can ensure that your stack remains stable and consistent over time.
