A company is using Microsoft Entra ID to manage identities for a multi-tenant SaaS application. They want to allow users from partner organizations to access the application using their own corporate credentials, without needing to manage separate accounts. Which solution should they implement?
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 solution because it enables partner users to access the company's multi-tenant SaaS application using their own corporate credentials, without requiring separate accounts. B2B collaboration supports cross-tenant access by creating lightweight guest user objects in the resource tenant, which can authenticate via their home tenant's identity provider. This aligns with the requirement to allow partner organizations to use their existing credentials while avoiding account management overhead.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here

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, mistakenly thinking both handle external users, but B2C is for customer identities (social/local accounts) while B2B is for partner identities (corporate credentials).
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Entra B2B collaboration leverages the SAML and OIDC protocols to perform cross-tenant authentication, where the resource tenant issues a token after the user authenticates in their home tenant. A subtle behavior is that B2B collaboration supports direct federation with identity providers that are not Microsoft Entra tenants, such as Google or SAML/WS-Fed providers, by using the 'direct federation' feature. In a real-world scenario, a company with a multi-tenant SaaS app can invite partner users via email, and those users will be redirected to their own corporate IdP for authentication, with the guest user object automatically created in the resource tenant's directory.

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.
