AWS Technical Essentials 2025 – 400 Free Practice Questions to Pass the Exam

AWS CloudFormation serves the function of allowing users to define and provision AWS infrastructure as code. This means that users can use CloudFormation templates, which are JSON or YAML formatted text files, to describe the resources needed for their applications, such as EC2 instances, S3 buckets, or RDS databases.

By treating infrastructure as code, CloudFormation enables automated provisioning and management of AWS resources in a consistent and repeatable manner. This approach eliminates the need for manual intervention and reduces the potential for errors during deployments. It also enables collaboration among development and operations teams, as infrastructure configurations can be version-controlled just like application code.

The other options represent different AWS functionalities but do not accurately describe the primary function of AWS CloudFormation. For instance, while some services may provide user interfaces, that isn’t the purpose of CloudFormation, which is more focused on automation and infrastructure management. Similarly, automating billing and cost management does not align with CloudFormation’s capabilities, which center around infrastructure deployment. Lastly, integrating machine learning capabilities pertains to other AWS services and is not the primary role of CloudFormation.
