Explore CloudFormation template anatomy

At NovaTech, your team is standardizing CloudFormation templates. Use the CloudFormation template explorer to examine how templates are structured. The explorer shows all six sections (Resources, Parameters, Outputs, Mappings, Conditions, Transform) and lets you toggle each one to see examples.

Pay attention to how intrinsic functions connect the sections: !Ref references Parameters and Resources, !GetAtt reads resource attributes like ARNs, and !Sub substitutes variables into strings.

Question: A CloudFormation template has a Parameter called EnvName and a Lambda function resource. Which intrinsic function inserts the value of EnvName into a string like "my-app-${EnvName}-bucket"?
