Question 486 of 975

Implement and manage identity and access in Microsoft Entra ID →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is to enable 'External identities' > 'Self-service sign-up' in Azure AD. This configuration is correct because it allows external users from a partner company to sign up for access to a SharePoint Online site using their own Azure AD accounts without requiring manual admin intervention, as the self-service sign-up flow automatically creates guest user objects in your tenant. On the Microsoft 365 Administrator MS-102 exam, this scenario tests your understanding of Azure AD External Identities and how they integrate with SharePoint Online’s sharing model; a common trap is confusing this with SharePoint’s external sharing settings, which control site-level permissions but not the identity provisioning process. Remember that self-service sign-up handles the *creation* of guest accounts, while SharePoint external sharing controls *access* to content. A useful memory tip is “SSU for IDs, SharePoint for access”—self-service sign-up provisions the identity, then SharePoint policies govern what they can see.

Full question →

A
Enable 'Email one-time passcode authentication' for guests
Why wrong: Email one-time passcode is an authentication method for users without Azure AD accounts, not for allowing self-service sign-up.
B
Enable 'External identities' > 'Self-service sign-up' in Azure AD
This setting allows external users to sign up for access to resources using their own Azure AD or Microsoft account identities.
C
Configure a cross-tenant access policy for the partner tenant
Why wrong: Cross-tenant access policies control inbound/outbound trust settings, but don't enable self-service sign-up; users still need to be invited or sign up.
D
Create guest user accounts manually in Azure AD
Why wrong: Manual creation does not allow self-service sign-up; the requirement is for users to sign up themselves.

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

✓

Enable 'External identities' > 'Self-service sign-up' in Azure AD

Option B is correct because enabling 'Self-service sign-up' in Azure AD External Identities allows external users to sign up for access to applications (including SharePoint Online sites) using their own Azure AD accounts without manual admin intervention. This feature creates guest user objects automatically when the external user completes the sign-up flow, which satisfies the requirement for partner users to sign up using their existing Azure AD credentials.

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

The trap here is that candidates often confuse 'self-service sign-up' with 'cross-tenant access policies' or 'email OTP,' thinking that any guest authentication method enables self-service sign-up, but only the explicit self-service sign-up feature creates the automated user provisioning flow.

Detailed technical explanation

How to think about this question

Self-service sign-up leverages Azure AD B2B collaboration to create guest user objects with a UserType of 'Guest' when an external user signs up via a company-branded portal. The sign-up flow uses OpenID Connect and OAuth 2.0 to authenticate the external user against their home tenant, and the resulting guest account is added to the resource tenant's directory with a configurable attribute set (e.g., allowed domains). In a real-world scenario, this is useful for partner onboarding where you want to avoid manual provisioning but still enforce domain restrictions via allowed domain lists.

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.

TExam Day Tips

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Variation 1. A company uses Azure AD and SharePoint Online. They want to allow users from a partner organization (which also uses Azure AD) to access a specific SharePoint Online site using their existing partner credentials. The partner users should not require new accounts to be created. Which Azure AD feature should be configured?

medium

✓ A.Azure AD B2B collaboration
B.Azure AD B2C
C.Azure AD Domain Services
D.Organizational Relationships

Why A: Azure AD B2B collaboration allows you to invite external users from a partner organization to access your Azure AD-integrated applications, such as SharePoint Online, using their own existing Azure AD credentials. This feature leverages cross-tenant trust and does not require creating new user accounts in your tenant, fulfilling the requirement exactly.
