Microsoft 365 Certified: Copilot and Agent Administration Fundamentals AB-900 Book

The correct answer is B. using a custom agent that is grounded in work data . Microsoft Learn states that agents that access shared tenant data , such as SharePoint or Graph Connector content, are billed based on metered consumption . Microsoft also describes pay-as-you-go for Microsoft 365 as applying to agents in Microsoft 365 Copilot Chat , where organizations pay only for the messages used instead of assigning a full Microsoft 365 Copilot license. That is exactly the scenario described in option B: a custom agent grounded in work data.

The other options are not the intended pay-as-you-go scenario. A Teams meeting recap and Copilot in Word are standard Microsoft 365 Copilot application experiences tied to licensed Copilot functionality, not metered agent consumption. Researcher is an advanced Microsoft 365 Copilot agent available as part of Microsoft 365 Copilot capabilities, not the documented example of pay-as-you-go replacing a Copilot license. Microsoft’s pay-as-you-go guidance centers on agent-based usage , especially agents grounded in organizational work data.

The correct answer is D. the Microsoft 365 admin center . Microsoft Learn states that users with a Microsoft 365 Copilot license can use Copilot capabilities, and Microsoft specifically points administrators to the Microsoft 365 admin center and its setup guidance to assign the required licenses to users. Microsoft also documents that the Researcher and Analyst agents were deployed to existing users with Microsoft 365 Copilot licenses and that administrators govern these agents through the Microsoft 365 admin center .

The other portals are not the primary place for this task. Microsoft Entra admin center focuses on identity and access, Microsoft Purview focuses on compliance and governance, and Microsoft Defender focuses on security operations and threat protection. None of those is the main admin experience Microsoft documents for assigning Microsoft 365 Copilot access and managing the availability of Researcher and Analyst. Because the goal is to enable a user to use Microsoft 365 Copilot and its Microsoft-provided agents, the correct administrative tool is the Microsoft 365 admin center .
