A company uses AWS CloudFormation to deploy resources and needs to update an existing stack. What should the company examine to understand how the proposed changes will affect currently running resources?

Reviewing change sets for the stack is the correct approach because AWS CloudFormation change sets allow you to preview how proposed changes to your stack will impact existing resources before you implement them. This includes identifying resources that will be created, modified, or deleted. Reviewing stack policies is incorrect because stack policies define which actions can be performed on specific resources during a stack update, but they don't show the effect of a proposed change. Reviewing the Metadata section of the template is incorrect as Metadata provides information about the template itself, not the impact of changes. Reviewing the Resources section of the template is incorrect because while it defines the resources, it doesn't show the difference between the current state and the proposed new state after an update.
