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

AWS CloudFormation is a service designed to help you model and set up your Amazon Web Services resources so that you can spend less time managing those resources and more time focusing on your applications. The correct answer emphasizes that CloudFormation creates and provisions AWS resources through templates. These templates are written in JSON or YAML and enable you to define the desired state of your architecture clearly and concisely.

This means that you can automate the creation of a collection of related AWS resources, manage them as a single unit (called a stack), and allow for easy updates, version control, and rollback functionality. By specifying the desired configurations and dependencies in the templates, CloudFormation automates the complexities of resource management, which is key to its purpose.

The other options, while related to different functionalities within AWS, do not fully capture the essence of what AWS CloudFormation is about. For example, simply creating instances is too narrow and does not showcase the full scope of resource management, while designing resources is not an accurate representation of the provisioning aspects. Meanwhile, keeping a watch on AWS resources pertains more to monitoring solutions within AWS, which is outside the direct scope of CloudFormation's purpose.
