A SysOps Administrator has an AWS CloudFormation template of the company’s existing infrastructure in us-west-2. The Administrator attempts to use the template to launch a new stack in eu-west-1, but the stack only partially deploys, receives an error message, and then rolls back.
Why would this template fail to deploy? (Choose two.)

A. The template referenced an IAM user that is not available in eu-west-1
B. The template referenced an Amazon Machine Image (AMI) that is not available in eu-west-1
C. The template did not have the proper level of permissions to deploy the resources
D. The template requested services that do not exist in eu-west-1
E. CloudFormation templates can be used only to update existing services
