Why would this template fail to deploy?
(Choose two.)
The template referenced an IAM user that is not available in eu-west-1
The template referenced an Amazon Machine Image (AMI) that is not available in eu-west-1
The template did not have the proper level of permissions to deploy the resources
The template requested services that do not exist in eu-west-1
CloudFormation templates can be used only to update existing services
Explanations:
IAM users are global resources in AWS, meaning they are not region-specific. Thus, referencing an IAM user in the template would not cause a failure.
AMIs are region-specific. If the template references an AMI that is not available in eu-west-1, the stack deployment will fail.
The issue described is related to a failed resource deployment due to regional differences, not permissions. Permissions would affect the ability to create resources, but not regional availability.
Some AWS services are region-specific. If the template requests services that are not available in eu-west-1, the stack will fail to deploy.
CloudFormation templates are used for creating and managing resources, not just updating existing services. Therefore, this option does not apply.
If I had to guess, I’d say the answer is:
The template referenced an Amazon Machine Image (AMI) that is not available in eu-west-1
