AWS Certified Developer – Associate (DVA-C02) — Question 331

A company is using AWS CloudFormation templates to deploy AWS resources. The company needs to update one of its AWS CloudFormation stacks.

What can the company do to find out how the changes will impact the resources that are running?

Answer options

• A. Investigate the change sets.
• B. Investigate the stack policies.
• C. Investigate the Metadata section.
• D. Investigate the Resources section.

Correct answer: A

Explanation

AWS CloudFormation change sets allow you to preview how proposed changes to a stack might impact your running resources before actually implementing them. Stack policies are used to protect specific stack resources from unintentional updates, while the Metadata and Resources sections define template-specific metadata and the actual resources to be provisioned, rather than showing the impact of an update.
