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 uses Microsoft Entra ID and wants to provide external business partners with access to a specific internal application. The partners already use Microsoft Entra ID in their own organization. The company wants the partners to use their existing corporate credentials to sign in, without creating new user accounts in the company's tenant. The company also wants to manage the access lifecycle, including automatically removing access after a project ends. Which Microsoft Entra ID feature should they use?
Correct. B2B collaboration enables external partners to use their own corporate identities to access apps in your tenant, with full lifecycle management capabilities.
B
Microsoft Entra B2C
Why wrong: B2C is designed for customer-facing applications where users can sign in with social or local accounts, not for business partner access using existing Azure AD credentials.
C
Identity Protection
Why wrong: Identity Protection detects and responds to identity-based risks; it does not provide external user access or guest lifecycle management.
D
Privileged Identity Management (PIM)
Why wrong: PIM manages just-in-time privileged roles for internal users, not the onboarding or lifecycle of external partner users.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Entra B2B collaboration
Microsoft Entra B2B collaboration is the correct feature because it allows external users from partner organizations who already have their own Microsoft Entra ID accounts to sign in using their existing corporate credentials, without requiring new user accounts in the company's tenant. It also supports access lifecycle management through features like entitlement management and access reviews, enabling automatic removal of access when a project ends.
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 B2B collaboration (for business partners with existing corporate identities) with B2C (for customers using social or local accounts), leading them to select B2C when the scenario clearly describes partner organizations using their own corporate credentials.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Entra B2B collaboration uses the SAML 2.0 or WS-Federation protocol to federate with the partner's Microsoft Entra ID tenant, enabling cross-tenant trust without duplicating identities. A real-world scenario where this matters is when a company needs to grant time-limited access to a project management application; by using B2B collaboration with entitlement management, access can be automatically revoked when the project ends via access reviews or expiration policies.

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.
