- A
Microsoft Entra Connect
Why wrong: Microsoft Entra Connect is used to synchronize on-premises directories with Microsoft Entra ID, not to invite external users with their own identity providers.
- B
Microsoft Entra External Identities (B2B collaboration)
B2B collaboration allows you to invite external users to your tenant using their own identities (e.g., Google, Facebook, or any Microsoft Entra ID tenant). Combined with Conditional Access, you can enforce MFA for those guest users.
- C
Microsoft Entra Identity Protection
Why wrong: Identity Protection detects and responds to identity-based risks, but it does not provide the ability to invite external users or allow them to authenticate with their own IdPs.
- D
Microsoft Entra Privileged Identity Management (PIM)
Why wrong: PIM provides just-in-time access to privileged roles inside the organization, not for external user access or identity federation.
External Identities B2B Collaboration: Granting Partner Access with MFA Enforcement
This SC-900 practice question tests your understanding of describe the capabilities of microsoft entra. 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.
A company wants to allow external business partners to access a specific SharePoint Online site using their own corporate identities (such as Google or Facebook accounts). The company also needs to enforce multi-factor authentication (MFA) for these external users. Which Microsoft Entra capability should the administrator configure?

Correct answer & explanation
Microsoft Entra External Identities (B2B collaboration)
Microsoft Entra External Identities (B2B collaboration) allows you to invite external users (including those with social identities like Google or Facebook) to access your organization's resources using their own identities. It supports conditional access policies, including the enforcement of multi-factor authentication (MFA) for guest users, which meets both requirements.
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 Microsoft Entra Connect (which handles hybrid identity sync) with External Identities (which handles guest user access), or they assume Identity Protection or PIM can be used to grant external access, when they are security monitoring and privilege management tools respectively.
Detailed technical explanation
How to think about this question
B2B collaboration uses the SAML/WS-Federation or OIDC protocols to allow external users to authenticate with their own identity providers (e.g., Google, Facebook). The MFA enforcement is achieved by applying a Conditional Access policy that targets guest/external users and requires MFA, which is evaluated at the resource tenant level, not the home tenant. In a real-world scenario, if a guest user's home tenant does not support MFA, the resource tenant can still require MFA via its own policies, but the user must register for MFA in the resource tenant.
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 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.

Same concept, more angles
3 more ways this is tested on SC-900
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company wants to allow external business partners to access its internal applications using their own corporate credentials (e.g., their Microsoft Entra ID or Google account), without creating separate user accounts in the company's directory. Which Microsoft Entra ID feature should they use?
medium- A.Azure AD B2C (Business-to-Consumer)
- ✓ B.B2B collaboration
- C.Microsoft Entra Domain Services
- D.Conditional Access
Why B: B2B collaboration allows the company to grant external business partners access to its internal applications using their own corporate identities (such as Microsoft Entra ID or Google accounts) without creating separate user accounts in the company's directory. It leverages federation trust and cross-tenant authentication, enabling partners to authenticate with their home organizations while accessing resources in the host tenant.
Variation 2. A company needs to allow external business partners to securely access internal SharePoint Online sites and Teams channels. The partners use various identity providers, including Microsoft Entra ID and Google. The company wants to manage these external users in their directory and assign access policies. Which Microsoft Entra ID capability should they use?
easy- A.Microsoft Entra B2C (Business to Customer)
- ✓ B.Microsoft Entra External ID (B2B Collaboration)
- C.Microsoft Entra Domain Services
- D.Microsoft Entra Identity Protection
Why B: Microsoft Entra External ID (B2B Collaboration) is the correct capability because it allows the company to invite external business partners (B2B users) from any identity provider, including Microsoft Entra ID and Google, into their own Microsoft Entra directory. This enables the company to manage these external users in their directory, assign conditional access policies, and grant them secure access to internal SharePoint Online sites and Teams channels without requiring a separate application or customer-facing identity system.
Variation 3. A company wants to allow its partners to access a specific SharePoint Online site using their own corporate credentials. The company does not want to manage partner accounts. Which Microsoft Entra feature should they use?
medium- ✓ A.Microsoft Entra External ID
- B.Microsoft Entra Privileged Identity Management
- C.Microsoft Entra Identity Protection
- D.Microsoft Entra Conditional Access
Why A: Microsoft Entra External ID (formerly Azure AD B2B) allows organizations to grant external partners access to resources like SharePoint Online using their own corporate or social identities. This eliminates the need to create and manage separate user accounts for partners, as they authenticate through their home identity provider via federation or invitation redemption.
