AWS Certified SysOps Administrator – Associate (SOA-C03) — Question 51

A CloudOps engineer has an AWS CloudFormation template of the company's existing infrastructure in us-west-2. The CloudOps engineer 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.)

Answer options

• 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

Correct answer: B, D

Explanation

The correct answers are B and D because the AMI must be available in the specified region for deployment, and certain AWS services may not exist in eu-west-1, causing the stack to fail. Options A and C are incorrect as they do not directly relate to region-specific deployment failures, and option E is false since CloudFormation templates can be used for both creating and updating resources.
