You need to implement a solution that allows external partners to access specific SharePoint Online sites without creating guest user objects in Microsoft Entra ID. The partners will authenticate using their own identity provider. What should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SharePoint Online external sharing with one-time passcode authentication
Option D is correct because SharePoint Online external sharing with one-time passcode authentication allows external partners to access SharePoint sites without creating guest user objects in Microsoft Entra ID. When the partner's identity provider is not federated with Entra ID, the one-time passcode feature sends a code to their email for authentication, bypassing the need for a guest account. This meets the requirement of no guest user objects while enabling access from an external identity provider.
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 (which always creates guest objects) with SharePoint external sharing features that can bypass guest object creation, leading them to select A or B instead of D.
Detailed technical explanation
How to think about this question
SharePoint Online external sharing with one-time passcode authentication leverages the 'Email one-time passcode' feature in Microsoft Entra ID, which is enabled by default for external sharing scenarios. When a partner authenticates via a one-time passcode, Entra ID does not create a guest user object; instead, it uses a transient token tied to the email address for the session. This is particularly useful in scenarios where partners use non-federated identity providers (e.g., Gmail, Yahoo) and you want to avoid polluting your directory with guest accounts.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
