Which file is used to configure global settings in a SFCC project?

In a Salesforce Commerce Cloud (SFCC) project, the file utilized to configure global settings is dw.json. This file is critical for managing various environment configurations, including API versions, application settings, and credentials necessary for the proper functioning of the application across different environments, such as development, staging, and production.

The dw.json file is structured in a way that allows developers to define configurations that are essential for the entire project, rather than settings that apply only to specific modules or features. It supports deploying the application with the correct context and behavior, making it an integral part of the SFCC setup.

The other options represent files that may contain different types of settings or configurations but do not serve as the primary source for global project settings. For instance, settings.json or config.json may pertain to specific configurations related to particular modules or packages rather than global project settings. The use of dw.json ensures that the correct information is applied universally across the application, making it the right choice in this context.
