Which TWO solutions should you recommend? (Select TWO)
Answer options:
A.
Microsoft Entra External ID (B2B) for the Partner Portal
B.
Azure AD B2C for the Customer Portal
C.
Azure AD B2C for the Partner Portal
D.
Microsoft Entra External ID (B2B) for the Customer Portal
E.
Active Directory Federation Services (AD FS) for both portals
How to approach this question
Match the audience to the service: B2B is for business partners (corporate identities), B2C is for consumers (social/local identities).
Full Answer
Microsoft Entra External ID (formerly Azure AD B2B) is the correct choice for the Partner Portal because it allows partner organizations to use their own corporate credentials, simplifying lifecycle management. Azure AD B2C is the correct choice for the Customer Portal because it is a Customer Identity Access Management (CIAM) solution designed to scale to millions of users and natively supports social identity providers like Facebook and Google.
Common mistakes
Thinking B2B and B2C are interchangeable. They serve entirely different architectural use cases.
