Microsoft Azure Architect Design (AZ-301) Practice Exam

What is the primary benefit of using Azure AD B2C for certain applications?

1. Support for high volumes of authentication requests.

2. Multi-tenancy capabilities.

3. Support for personal accounts and multi-factor authentication.

4. Integrated support for legacy applications.

The correct answer is: Support for personal accounts and multi-factor authentication.

The primary benefit of using Azure AD B2C is its support for personal accounts and multi-factor authentication. This service is designed to handle customer identity and access management, allowing businesses to provide a seamless sign-up and sign-in experience for their customers using personal accounts, such as social media logins (like Facebook or Google) and custom email/password combinations. Furthermore, Azure AD B2C includes robust multi-factor authentication options, enhancing security by requiring users to verify their identity through additional means, such as SMS messages or authenticator apps. This makes it particularly valuable for applications where secure customer authentication is critical, such as e-commerce platforms or services that handle sensitive information. The other options, while relevant in different contexts, do not capture the specific focus of Azure AD B2C on customer identity. For example, high volumes of authentication requests may be a consideration for Azure AD in general but does not specifically highlight the unique characteristics of B2C. Multi-tenancy is a feature that is typically associated with both Azure AD and Azure AD B2C, but the emphasis on personal accounts and multi-factor authentication distinctly separates B2C from other Azure services. Finally, integrated support for legacy applications would pertain more to Azure AD or other enterprise-related features
