SC-300 Certification Practice Question #79

Question

You have a Microsoft Entra tenant named contoso.com that has cross-tenant access configured as shown in the following table.

You have two partner organizations named Fabrikam, Inc. and A. Datum Corporation. Fabrikam has a Microsoft 365 domain named fabrikam.com. A. Datum has a Microsoft 365 domain named adatum.com.

You configure cross-tenant access for fabrikam.com as shown in the following table.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.

NOTE: Each correct selection is worth one point.

Accepted Answer

Cross-tenant access settings are directional. **Inbound** B2B collaboration controls who can be invited into contoso (i.e., whether contoso can *send* a guest invitation to an external user); **outbound** controls whether contoso's own users can be invited into / authenticate with an external org (i.e., whether a contoso user can *accept* an invitation from that org). For fabrikam.com the custom entry sets Inbound = All allowed and Outbound = All blocked, so statement 1 (send to fabrikam) is Yes and statement 3 (accept from fabrikam = contoso user joining fabrikam, an outbound action) is No. A. Datum has no organizational entry, so it falls back to the default settings, which here are All blocked in both directions, making statement 2 (send to adatum) No. The top-voted comment (VidJay, 2 👍) reaches the same Y, N, N and its directional reasoning matches MS Learn; the two lower-voted dissenters mis-read the inbound-allowed entry for fabrikam. Confidence is held at 84 rather than higher because no official Suggested Answer is recorded and total community volume is low.
