The developer decides to update the Amazon EC2 Auto Scaling launch template with new Amazon Machine Images (AMIs) for each environment. The
CloudFormation update for the new AMIs is successful in the test environment, but the update fails in the production environment.
What are the possible causes of the CloudFormation update failure in the production environment? (Choose two.)
