What is a key benefit of AWS CloudFormation?

1. Enables automated scaling of EC2 instances

2. Facilitates the management of multiple resources as a single unit

3. Provides a direct connection to AWS support

4. Enhances security for AWS resources

The correct answer is: Facilitates the management of multiple resources as a single unit

A key benefit of AWS CloudFormation is its ability to facilitate the management of multiple resources as a single unit. This means that users can define an entire infrastructure stack using a simple template, written in JSON or YAML, which describes all the resources needed for a specific application or service. By using this approach, any changes to the infrastructure, such as updates or modifications, can be easily managed. When you need to provision, update, or delete resources, you can do so through a single operation. This dramatically improves consistency and reduces the potential for errors, as all resources are managed in tandem rather than individually. This overall simplification of infrastructure management allows for better deployment practices, easier updates, and streamlined documentation of resource configurations. While the other options list important features and advantages of different AWS services, they do not pertain directly to the core functionality that CloudFormation offers in the context of resource management.
