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 uses Microsoft Entra ID. They frequently collaborate with an external partner organization. The IT team wants to allow the partner's users to access the company's internal SharePoint site using their existing corporate credentials from their own Microsoft Entra tenant. The partner users should not have to create separate guest accounts or remember another password. Which Microsoft Entra feature should the IT team configure?
Why wrong: B2C is for customer identity and access management, designed for consumer-facing applications, not for B2B collaboration with partner organizations.
B
Microsoft Entra B2B collaboration
Correct. B2B collaboration lets external partners use their own work or school accounts to access your resources, enabling seamless collaboration without additional credentials.
C
Microsoft Entra Domain Services
Why wrong: Domain Services provides managed domain services like domain join and group policy, not external identity collaboration.
D
Microsoft Entra Application Proxy
Why wrong: Application Proxy allows secure remote access to on-premises web applications, but does not handle external identities from other tenants.

Correct answer & explanation
✓
Microsoft Entra B2B collaboration
Microsoft Entra B2B collaboration is the correct feature because it enables external users from a partner organization to access the company's internal SharePoint site using their own corporate credentials from their Microsoft Entra tenant. B2B collaboration creates a guest user object in the resource tenant without requiring separate guest accounts or additional passwords, leveraging cross-tenant trust and SAML/WS-Federation for authentication.
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 with B2C, thinking both are for external users, but B2C is for consumers with self-service sign-up, while B2B is for business partners using their existing corporate identities.
Detailed technical explanation
How to think about this question
Under the hood, B2B collaboration uses the SAML 2.0 or WS-Federation protocol to establish trust between the resource tenant and the partner's tenant. When a partner user accesses the SharePoint site, Entra ID issues a token based on the partner's home tenant authentication, and the resource tenant's conditional access policies can still apply. In real-world scenarios, B2B collaboration supports cross-tenant access settings that allow granular control over inbound and outbound trust, including multifactor authentication from the home tenant.

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.
