AWS Certified Solutions Architect – Associate (SAA-C02) — Question 591

A company is making a prototype of the infrastructure for its new website by manually provisioning the necessary infrastructure. This infrastructure includes an
Auto Scaling group, an Application Load Balancer, and an Amazon RDS database. After the configuration has been thoroughly validated, the company wants the capability to immediately deploy the infrastructure for development and production use in two Availability Zones in an automated fashion.
What should a solutions architect recommend to meet these requirements?

Answer options

• A. Use AWS Systems Manager to replicate and provision the prototype infrastructure in two Availability Zones.
• B. Define the infrastructure as a template by using the prototype infrastructure as a guide. Deploy the infrastructure with AWS CloudFormation.
• C. Use AWS Config to record the inventory of resources that are used in the prototype infrastructure. Use AWS Config to deploy the prototype infrastructure into two Availability Zones.
• D. Use AWS Elastic Beanstalk and configure it to use an automated reference to the prototype infrastructure to automatically deploy new environments in two Availability Zones.

Correct answer: B

Explanation

AWS CloudFormation is the standard Infrastructure as Code (IaC) service designed to define and provision AWS resources repeatedly and reliably using templates. AWS Systems Manager and AWS Config are meant for operational management and compliance auditing, respectively, rather than resource provisioning. AWS Elastic Beanstalk simplifies application deployment but does not automatically convert manually created infrastructure into repeatable environment templates.
