A team wants to provision identical infrastructure stacks for dev, stage, and production from one CloudFormation template. Which mechanism makes the same template environment-specific?

• AA. Use CloudFormation Parameters and reference per-environment values from an SSM Parameter Store SecureString using dynamic references
• BB. Duplicate the template three times and hand-edit each copy
• CC. Hard-code the production values and override at runtime via the console
• DD. Use multiple AWS accounts and rewrite the template per account
