AWS Certified Solutions Architect – Professional — Question 42

How can you check the operational validity of your AWS CloudFormation template?

Answer options

• A. To check the operational validity, you need to attempt to create the stack.
• B. There is no way to check the operational validity of your AWS CloudFormation template.
• C. To check the operational validity, you need a sandbox or test area for AWS CloudFormation stacks.
• D. To check the operational validity, you need to use the aws cloudformation validate-template command.

Correct answer: A

Explanation

The correct answer is A because the only definitive way to check if a CloudFormation template is operationally valid is to create the stack based on it. Option B is incorrect as there are methods to check validity, option C is misleading since a sandbox is not necessary for this validation, and option D, while it provides a way to validate syntax, does not confirm operational validity.
