Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Microsoft Entra B2B collaboration to invite partners as guest users.
Microsoft Entra B2B collaboration is the correct feature because it allows you to invite external partners as guest users who can access resources like SharePoint Online using their own identity (e.g., a Microsoft account or a corporate account from another identity provider) without requiring a separate Microsoft Entra ID account in your tenant. This leverages the B2B collaboration protocol, which uses SAML/WS-Federation or OIDC for federation, enabling seamless access while maintaining centralized access control.
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 B2B collaboration with Microsoft Entra B2C, assuming both are for external users, but B2C is for customer-facing apps with self-service sign-up, while B2B is for granting access to business partners with existing identities.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Entra B2B collaboration uses a redemption process where the invited partner receives an email with a link to accept the invitation; upon acceptance, a guest user object is created in the tenant, and the partner authenticates using their home identity provider. This allows the partner to access SharePoint Online via a direct link or through the Azure portal, with access controlled by conditional access policies that can be applied to guest users. In a real-world scenario, you might invite a vendor's employee using their work email, and they will authenticate with their own company's IdP, eliminating the need to manage separate credentials.

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.
