Your CloudFormation template launches a two-tier web application in us-east-1. When you attempt to create a development stack in us-west-1, the process fails. What could be the problem?

• The AMIs referenced in the template are not available in us-west-1

• The IAM roles referenced in the template are not valid in us-west-1

• Two ELB Classic Load Balancers cannot have the same Name tag

• CloudFormation templates can be launched only in a single region

Answer explanation

AMIs are stored in a region and cannot be accessed in other regions. To use the AMI in another region, you must copy it to that region. IAM roles are valid across the entire account.

Answer explanation

You can use the Parameters section to take in values at runtime. You can then use the values of those parameters to define how the template gets executed.
