AWS Certified Developer – Associate — Question 207

An AWS Elastic Beanstalk application needs to be deployed in multiple regions and requires a different Amazon Machine Image (AMI) in each region.

Which AWS CloudFormation template key can be used to specify the correct AMI for each region?

Answer options

• A. Parameters
• B. Outputs
• C. Mappings
• D. Resources

Correct answer: C

Explanation

The correct answer is C, Mappings, as this key allows you to define specific values based on conditions such as region. The other options do not serve this purpose: A (Parameters) is used for input values, B (Outputs) is for returning information after stack creation, and D (Resources) defines the resources to be created.
