Question 24
A global e-commerce company wants to perform geographic load testing of its order processing API. The company must deploy resources to multiple AWS Regions to support the load testing of the API.
How can the company address these requirements without additional application code?
-
A
Set up an AWS CloudFormation template that defines the load test resources. Leverage the AWS CLI create-stack-set command to create a stack set in the desired Regions
-
B
Set up an AWS Cloud Development Kit (CDK) ToolKit that defines the load test resources. Leverage the CDK CLI to create a stack from the template in each Region
-
C
Set up an AWS Organizations template that defines the load test resources across the organization. Leverage the AWS CLI create-stack-set command to create a stack set in the desired Regions
-
D
Set up an AWS CloudFormation template that defines the load test resources. Develop region-specific Lambda functions to create a stack from the AWS CloudFormation template in each Region when the respective function is invoked

Correct answer: A
Explanation
Correct option:
Set up an AWS CloudFormation template that defines the load test resources. Leverage the AWS CLI create-stack-set command to create a stack set in the desired Regions
AWS CloudFormation StackSets extends the capability of stacks by enabling you to create, update, or delete stacks across multiple accounts and AWS Regions with a single operation. Using an administrator account, you define and manage an AWS CloudFormation template, and use the template as the basis for provisioning stacks into selected target accounts across specified AWS Regions.
A stack set lets you create stacks in AWS accounts across regions by using a single CloudFormation template. A stack set's CloudFormation template defines all the resources in each stack. As you create the stack set, specify the template to use, in addition to any parameters and capabilities that the template requires.
After you've defined a stack set, you can create, update, or delete stacks in the target accounts and AWS Regions you specify.
Incorrect options:
Set up an AWS CloudFormation template that defines the load test resources. Develop region-specific Lambda functions to create a stack from the AWS CloudFormation template in each Region when the respective function is invoked - If you do not use a stack set, then you need to define the CloudFormation templates in each region as well as develop lambda functions in each region to create a stack from the corresponding CloudFormation template. This is unnecessary bloat that can be avoided by simply using the CloudFormation StackSets.
Set up an AWS Cloud Development Kit (CDK) ToolKit that defines the load test resources. Leverage the CDK CLI to create a stack from the template in each Region - AWS CDK is a framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. The CDK Toolkit again poses regional limitations and is not the right fit for the given use case.
Set up an AWS Organizations template that defines the load test resources across the organization. Leverage the AWS CLI create-stack-set command to create a stack set in the desired Regions - This option acts as a distractor. AWS Organizations cannot be used to create templates for provisioning AWS infrastructure. AWS Organizations is an account management service that enables you to consolidate multiple AWS accounts into an organization that you create and centrally manage.
