SC-100 Certification Practice Question #156

Question

A customer uses Azure to develop a mobile app that will be consumed by external users as shown in the following exhibit.

You need to design an identity strategy for the app. The solution must meet the following requirements:
✑ Enable the usage of external IDs such as Google, Facebook, and Microsoft accounts.
✑ Use a customer identity store.
✑ Support fully customizable branding for the app.
Which service should you recommend to complete the design?

Accepted Answer

All three requirements point exclusively to Azure AD B2C. MS Learn describes B2C as a customer identity access management (CIAM) solution that is itself a customer identity store, lets external users sign in with social identities such as Google, Facebook, and Microsoft accounts, and is a white-label solution providing fully customizable (HTML/CSS/JS) branding. B2B handles guest invitations of external partners (not a consumer store), Azure AD DS provides managed domain services for legacy workloads, and Azure AD Connect only synchronizes on-premises AD to the cloud — none enable social-IdP consumer sign-in with custom branding. The official Suggested Answer and the community Most Voted both select C with no dissent, so confidence is high at 93.
