Correct answer & explanation
✓
The DBPassword parameter is not defined in the Parameters section
The template uses !Ref DBPassword, but DBPassword is not defined in the Parameters section of the template. CloudFormation requires parameters to be declared before they can be referenced. The other options are not indicated by the error message.
