Microsoft Azure Architect Design (AZ-301) Practice Exam

The primary purpose of Azure Active Directory B2C is to provide identity management for customer-facing applications. This service is designed specifically to help businesses implement secure authentication and authorization for their customers, enabling them to sign up, sign in, and manage their profiles while interacting with the application.

Azure Active Directory B2C allows businesses to customize the user experience in a way that reflects their branding and application needs, enhancing customer engagement and security. It supports various identity providers, such as social accounts (like Facebook or Google) as well as local accounts, offering flexibility for customers during the authentication process.

This focus on customer identity management distinctly differentiates Azure AD B2C from Azure Active Directory, which targets enterprise identity management, including employee identities and access to organizational resources. Therefore, the correct answer reflects the specialized role of Azure AD B2C in enabling businesses to cater directly to their customer base through identity services.
