- A
Use Microsoft Entra ID as the only identity provider and configure federation with Google and Facebook.
Why wrong: Microsoft Entra ID does not directly support consumer social logins; it is for enterprise identity.
- B
Use Microsoft Entra External ID with Google and Facebook only, and advise corporate users to create local accounts.
Why wrong: Corporate users should use their existing corporate identities, not create new local accounts.
- C
Configure Google and Facebook as social identity providers, and add Microsoft Entra ID as a custom identity provider.
Microsoft Entra External ID allows multiple identity providers, including social and enterprise Microsoft Entra ID tenants.
- D
Configure only Google and Facebook as identity providers, and use Microsoft account for corporate users.
Why wrong: Corporate users need to use their corporate Microsoft Entra ID, not personal Microsoft accounts.
Quick Answer
The answer is to configure Google and Facebook as social identity providers, and add Microsoft Entra ID as a custom identity provider. This is correct because Microsoft Entra External ID (formerly Azure AD B2C) natively supports social identity providers like Google and Facebook through its built-in federation, while corporate Microsoft Entra ID accounts must be added as a custom identity provider using OpenID Connect or SAML protocols to enable single sign-on for enterprise users. On the AZ-305 exam, this scenario tests your ability to distinguish between built-in social providers and custom corporate providers, often appearing in a multi-tenant authentication design question where you must support both consumer and enterprise identities. A common trap is assuming Microsoft Account can serve corporate users, but it only handles personal accounts, not corporate Entra ID tenants. Memory tip: think “Social = built-in, Corporate = custom” to avoid mixing up provider types.
AZ-305 Design infrastructure solutions Practice Question
This AZ-305 practice question tests your understanding of design infrastructure solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are designing an authentication solution for a mobile application that uses Azure AD B2C (now Microsoft Entra External ID). The application needs to support social logins (Google, Facebook) and also allow users to sign in with their corporate Microsoft Entra ID accounts. Which of the following identity providers should you configure?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure Google and Facebook as social identity providers, and add Microsoft Entra ID as a custom identity provider.
Option A is correct because Microsoft Entra External ID (formerly Azure AD B2C) supports both social identity providers and Microsoft Entra ID as a custom identity provider. Option B is wrong because Microsoft Entra ID alone does not support social logins. Option C is wrong because Microsoft account is not for corporate accounts. Option D is wrong because it doesn't include corporate identity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
