Quick Answer
The answer is Microsoft Entra B2B collaboration. This is the correct choice because B2B collaboration allows you to grant external partners access to specific SharePoint Online sites without creating full user objects in your Microsoft Entra ID; instead, it creates lightweight guest user objects that represent external identities, enabling partners to authenticate using their own organizational or social credentials while minimizing identity management overhead. On the MS-102 exam, this scenario tests your understanding of how to configure external access for SharePoint while avoiding unnecessary directory bloat—a common trap is confusing B2B collaboration with B2C or direct federation, which create separate identity stores. Remember that B2B collaboration is the go-to for partner access because it keeps guest objects lean and leverages the partner’s existing identity. Memory tip: think “B2B = Bring your own identity, no full user object created.”

Common exam traps
The trap here is that candidates often confuse Microsoft Entra B2B collaboration with Microsoft Entra B2C, mistakenly thinking B2C is for business partners when it is actually designed for consumer-facing applications.
Detailed technical explanation
Under the hood, Microsoft Entra B2B collaboration uses SAML 2.0 or OIDC to authenticate external users against their home identity providers, creating a guest user object in the resource tenant that is linked to the external identity. This guest object is not a full user object and does not consume a license unless additional features like MFA or conditional access are applied. In real-world scenarios, this allows organizations to maintain a clean directory while enabling cross-company collaboration on SharePoint sites.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
