Microsoft 365 Copilot and Agent Administration Fundamentals AB-900 Exam Questions with Experts Answers Updated Recently

The correct answer is Data access governance . Microsoft documents that Data access governance reports in the SharePoint admin center help administrators discover overshared or sensitive SharePoint content and assess sharing exposure. More specifically, Microsoft’s sharing links activity reports under Data access governance are designed to monitor sharing activity and identify sites where links such as Anyone , People in the organization , and Specific people links have been created. This is the SharePoint admin reporting area Microsoft provides for investigating external sharing patterns and related exposure.

The other listed reports do not fit this requirement. Agent insights is for Copilot/agent usage, App insights is for application-related insights, Change history tracks configuration changes, OneDrive accounts focuses on OneDrive administration, and Site policy comparison compares site settings. None of those is the SharePoint report family intended for identifying externally shared SharePoint content. Based on Microsoft’s documentation, the report area you should use is Data access governance .

The correct answer is View all the users in the Microsoft Entra tenant . In the exhibit, John is assigned the Global Reader role. Microsoft documents that the Global Reader role is intended for users who need to view administrator features and settings in admin centers that a Global Administrator can view, but without edit permissions. That makes it appropriate for read-only visibility into tenant-wide directory and admin information, including users in Microsoft Entra.

The other answer choices are not supported by the Global Reader role. Microsoft distinguishes admin-center visibility from access to content in workloads such as SharePoint sites and Exchange mailboxes . Global Reader is a read-only administrative role, not a content access role for reading all documents or mailbox items. Likewise, performing eDiscovery of Microsoft 365 Copilot prompts requires Purview eDiscovery permissions or role group membership, not merely the Global Reader role. Microsoft documents eDiscovery permissions separately in Purview role groups.

Therefore, based on the assigned role shown, the valid completion is that John can view all the users in the Microsoft Entra tenant .

The correct answer is Microsoft 365 Copilot . Microsoft Learn states that Restricted SharePoint Search (RSS) gives organizations time to review and correct permissions on SharePoint sites, and then add only those reviewed sites to an allowed list that Copilot can access . That means RSS is specifically about restricting Copilot’s access to SharePoint content, not blocking administrators, guest users, or Microsoft Purview eDiscovery from those sites.

This distinction is important. Microsoft explains that users can still access SharePoint content based on their normal permissions, while RSS limits what Microsoft 365 Copilot can use as grounding data until site permissions are reviewed and approved. So the feature helps reduce oversharing risk in Copilot without removing a user’s direct ability to find or open content they already have permission to access in SharePoint. In other words, the restriction is placed on Copilot’s searchable grounding scope , not on the user’s own SharePoint permissions. That is why the sentence is correctly completed with Microsoft 365 Copilot .
