Question 1

Your organization has a Microsoft 365 subscription.

Your company recently purchased Microsoft 365 Copilot licenses for some users.

You need to identify how many unlicensed users have used Copilot in Microsoft Teams.

Which usage report should you use in the Microsoft 365 admin center?



Answer : A


Question 2

You use Microsoft 365 Copilot.

You need to schedule a prompt to run at midnight.

What task should you include in your solution?



Answer : C


Question 3

Your organization has a Microsoft 365 subscription.

All users are assigned a Microsoft 365 Copilot license.

You need to prevent the users from generating images by using Copilot.

What should you use?



Answer : C

The correct answer is C. the Microsoft 365 admin center. Microsoft Learn documents a specific Copilot image generation setting in the Microsoft 365 admin center under Copilot > Settings > Copilot actions > Copilot image generation. Microsoft states that when this scenario is allowed, users can ask Copilot to create, design, and edit images. When it is not allowed, Copilot does not generate images and instead responds with stock or brand images. This directly matches the requirement to prevent users from generating images by using Copilot.

The other options are incorrect because Microsoft does not document this control as being managed from Defender, Purview, or Entra for this scenario. Microsoft also separately notes that organizations can control access to Designer image generation through policy, but the admin experience for managing the Microsoft 365 Copilot scenario itself is explicitly surfaced in the Microsoft 365 admin center. Therefore, for an exam question focused on where an admin should go to disable image generation in Copilot, the best and documented answer is the Microsoft 365 admin center.


Question 4

Your organization has a Microsoft 365 subscription.

You need to evaluate your organization's Identity Secure Score.

Which two factors affect the score? Each correct answer presents a complete the solution.

NOTE: Each correct selection is worth one point.



Answer : B, C

The correct answers are B and C. Microsoft documents that Identity Secure Score in Microsoft Entra is based on identity security recommendations, including recommendations such as ''Designate more than one Global Administrator'' and ''Do not expire passwords.'' Those recommendations directly map to the number of global administrators and whether passwords are set to never expire, so both factors affect the score.


Question 5

Your company plans to use Microsoft 365 Copilot.

You need to provide a user with the ability to use Microsoft 365 Copilot, including the Researcher and Analyst agent. What should you use?



Answer : D

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.


Question 6

Your organization has a Microsoft 365 subscription.

All users are assigned Microsoft 365 Copilot licenses.

Some users report receiving Copilot responses that contain information from a Microsoft SharePoint site named Finance. The users report that the information is commercially sensitive.

You need to prevent Copilot from providing responses that contain information from the Finance site.

What should you do?



Answer : D

The correct answer is D. From the Finance site, configure permissions. Microsoft states that Microsoft 365 Copilot honors existing Microsoft 365 permissions and only grounds responses in content that the signed-in user is already allowed to access. That means if users are getting Finance-site content in Copilot responses, those users likely still have permission to that SharePoint content. The direct fix is to review and correct the site, library, folder, or file permissions on the Finance site so only the intended users retain access.

The other options do not directly solve this requirement. Information Barriers are designed for communication and collaboration segmentation scenarios, not for ordinary site-level oversharing remediation. A Defender data connector is unrelated to SharePoint permission enforcement. Conditional Access controls sign-in and session access conditions, but it does not selectively remove Copilot grounding from one SharePoint site for users who still have site permissions. Because Copilot uses SharePoint and Microsoft Graph permissions as its boundary, the Microsoft-documented corrective action is to fix the Finance site permissions.


Question 7

Your company is evaluating Microsoft 365 Copilot pay-as-you-go billing instead of purchasing a Microsoft 365 Copilot license. In which scenario can pay-as-you-go billing apply?



Answer : B

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.
