AWS Certified Cloud Practitioner Test 2025 – 400 Free Practice Questions to Pass the Exam

AWS CloudFormation is a service that allows users to define and provision AWS infrastructure and resources using a declarative template language, often referred to as "infrastructure as code." This enables users to create and manage AWS resources through JSON or YAML templates. With CloudFormation, you can automate the setup and configuration of your infrastructure in a consistent and repeatable manner.

By defining your infrastructure in code, you can version control your templates, track changes over time, and deploy your infrastructure consistently across different environments. This is particularly useful for environments that require frequent changes or need to be replicated, such as development and production environments.

The other options relate to functionalities not provided by CloudFormation. For example, developing mobile applications and hosting scalable web services are not tasks directly associated with CloudFormation; rather, they pertain to other AWS services. Monitoring cloud resource performance involves services like Amazon CloudWatch, which is distinct from the infrastructure provisioning capabilities that CloudFormation provides.
