MS-102 Deploy and manage a Microsoft 365 tenant Practice Question
A company recently acquired another company and needs to allow users from the acquired tenant to access its SharePoint Online sites as guest users, but only if those users already have accounts in the acquired Azure AD tenant. Which Microsoft 365 feature should be configured?
⚠ Common exam trap
Many candidates confuse B2B direct connect with B2B collaboration, assuming both provide guest access to SharePoint, but B2B direct connect is limited to Teams shared channels and does not support SharePoint guest invitations.

Correct answer & explanation
✓
Cross-tenant access settings for B2B collaboration
Cross-tenant access settings for B2B collaboration allow you to configure inbound and outbound access between two Azure AD tenants. By enabling B2B collaboration with the acquired tenant and setting the appropriate cross-tenant access policies, you can invite users who already have accounts in that tenant as guest users to access SharePoint Online sites. This ensures that only authenticated users from the acquired tenant are granted access, meeting the requirement.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Cross-tenant access settings for B2B collaboration
Why this is correct
Cross-tenant access settings for B2B collaboration are the correct method for controlling and enabling guest access across Microsoft 365 tenants. These settings let you configure inbound and outbound access policies, apply cross-tenant trust for Multi-factor Authentication and device compliance, and set specific automatic redemption options. They govern SharePoint external sharing by controlling which external Azure AD tenants can authenticate and how their guest identities are treated, making this the correct tool for the scenario.
- ✗
B2B direct connect
Why it's wrong here
B2B direct connect is not the correct option because it is specifically intended for enabling Teams Connect shared channels with another organization. It establishes a two-way, real-time trust for channel access without creating guest user objects in your tenant, and it does not extend to SharePoint sites, document libraries, or general guest sharing. The scenario requires general cross-tenant guest collaboration, which B2B direct connect does not support.
- ✗
Multi-Geo
Why it's wrong here
Multi-Geo is irrelevant to this scenario because it addresses data residency and placement of inactive data into different geographic regions within the same Microsoft 365 tenant. It does not manage identity relationships, guest access, or cross-tenant authentication between separate organizations. Enabling Multi-Geo would not allow the acquired company's users to access your SharePoint sites because it has no effect on cross-tenant trust or B2B collaboration.
- ✗
Tenant Restrictions
Why it's wrong here
Tenant Restrictions are a conditional access-style control that limits which external tenants your users can access through their accounts, typically enforced via a proxy on managed networks. It is designed to prevent sign-ins to external Azure AD tenants, not to enable or configure cross-tenant guest access. Therefore, it would block collaboration rather than allow the acquired company's users to authenticate, making it incorrect for this requirement.
