AB-900 Microsoft 365 Copilot and Agent Administration Fundamentals Question and Answers

The correct answer is B. the Microsoft Purview DSPM for AI solution . Microsoft documents that Data Security Posture Management for AI (DSPM for AI) in Microsoft Purview provides a central place to secure data for AI apps and proactively monitor AI use , including Copilots and agents . Microsoft also states that DSPM for AI helps organizations identify where sensitive content is used in AI interactions , review Copilot prompts and responses , analyze usage patterns , assess exposure and oversharing risks, and get recommendations for protections such as sensitivity labels and DLP policy coverage.

The other options do not fit this requirement. Microsoft Viva Insights focuses on productivity and work-pattern analytics, not sensitive-data protection in Copilot interactions. Microsoft Security Copilot is a security assistant for analysts, not the Purview governance solution that analyzes sensitive content use in Copilot and recommends data protections. Insider Risk Management is for identifying risky user behavior, not for broad AI interaction posture analysis and protection recommendations. Microsoft specifically positions DSPM for AI as the “front door” for discovering, monitoring, and protecting AI-related data usage in Microsoft 365 Copilot.

The correct answer is Activate the role. Microsoft Learn states that in Microsoft Entra Privileged Identity Management (PIM), when a user is made eligible for a Microsoft Entra role, they do not immediately have the permissions of that role. Microsoft specifically explains that eligible users must activate the role assignment before using the role. Only after activation does the user receive the permissions associated with that role for the approved time period.

That means if you are only eligible for the User Administrator role, you cannot create user accounts until you activate that role in PIM. The other options are incorrect because installing Microsoft Authenticator, requesting a license, or updating location information are not the universal prerequisite stated by Microsoft for using an eligible PIM role. Multifactor authentication can be required during activation depending on policy, but the core required action is still to activate the role first. Microsoft also notes that activation can involve entering a reason, selecting a duration, and completing any required approval or MFA steps.

The correct answer is A. Microsoft 365 Copilot Chat. The requirement specifically asks for unlicensed users who used Copilot in Microsoft Teams. That points to Copilot Chat usage, not the standard Microsoft 365 Copilot licensed-user report. Microsoft’s usage documentation distinguishes Copilot Chat activity, including Copilot Chat work and web experiences, and lists Microsoft Teams as an entry point where users can access Copilot Chat. Microsoft also states that the Microsoft 365 Copilot usage report’s user-level table is scoped to users who were licensed for Microsoft 365 Copilot, which makes it the wrong report for identifying unlicensed Copilot Chat users. Microsoft 365 Apps and Copilot Search reports do not target this Teams Copilot Chat usage scenario.

The correct answer is C. the Microsoft 365 Copilot dashboard in Microsoft Viva Insights . Microsoft documents that the Microsoft Copilot Dashboard in Viva Insights provides detailed organizational reporting for Copilot usage and impact, including meeting-related metrics such as total meeting hours summarized or recapped , intelligent recap actions taken using Copilot , and summarize meeting actions taken using Copilot in Teams . Those metrics directly match the scenario in the question.

The other options are less suitable. The Microsoft 365 Apps usage report focuses on app usage generally, not detailed Copilot-in-Teams behavior. The Copilot readiness report is for readiness and deployment planning, not deep Teams usage metrics. The Microsoft 365 Copilot usage report in the admin center provides adoption information, but Microsoft’s detailed meeting-action and meeting-hours metrics are documented in the Viva Insights Copilot Dashboard . Therefore, for detailed Teams-specific Copilot reporting during a pilot, the best answer is the Microsoft 365 Copilot dashboard in Microsoft Viva Insights .

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 selections are Yes, Yes, No. Microsoft Purview sensitivity labels are used to classify and protect organizational data. Microsoft documents that sensitivity labels can protect content such as documents and emails, and it explicitly states that documents and emails can have sensitivity labels applied. Microsoft also supports sensitivity labels for containers, including Microsoft Teams, Microsoft 365 Groups, SharePoint sites, Viva Engage communities, and Loop workspaces. Therefore, a SharePoint site can be labeled, and an Exchange email message can be labeled. Windows 11 devices are different: they are managed and protected through endpoint management and security solutions such as Microsoft Intune and Microsoft Defender for Endpoint. Sensitivity labels apply to supported content and containers, not directly to Windows device objects.

In Microsoft 365 Copilot, you should use the Researcher agent to perform multi-step reasoning over unstructured data.

The correct answer is the Researcher agent . Microsoft describes Researcher in Microsoft 365 Copilot as an agent for complex, multi-step research that can reason across information sources and synthesize findings into structured outputs. That aligns with the phrase multi-step reasoning in the question. Microsoft’s guidance also contrasts Researcher with Analyst , which is aimed more at data analysis and spreadsheet-oriented tasks.

The other options are less suitable. Chat is general-purpose and not the specialized tool Microsoft positions for deeper multi-step research workflows. A notebook is used to organize materials and chats, not as the main reasoning engine for this scenario. The Analyst agent is better suited to structured data analysis, trends, and calculations rather than broad reasoning over unstructured data such as documents, notes, and mixed content. Based on Microsoft’s product positioning, the best fit for multi-step reasoning over unstructured information is the Researcher agent .

The correct answer is B. Data explorer. Microsoft Learn states that Data explorer in Microsoft Purview shows a current snapshot of items that have been classified as a sensitive information type in your organization. Microsoft’s sensitive information type documentation specifically lists examples such as social security numbers and credit card numbers, which means Data explorer is the appropriate portal feature for identifying files and emails that contain those data types. Data explorer is designed to help administrators see where sensitive data exists across supported Microsoft 365 locations.

The other options are less appropriate for this task. Information Protection reports focus more broadly on label and protection reporting. Information Protection policies are for configuring classification and protection behavior, not for finding existing files and emails containing SSNs or credit card numbers. Activity explorer is primarily used to review user and policy-related activities, such as label changes or DLP events, rather than to provide the direct sensitive-data inventory view requested here. Since the question asks to identify the files and emails containing specific sensitive information types, Microsoft’s documented answer is Data explorer.

The correct selections are No, Yes, No . Microsoft defines Zero Trust as a security strategy and explicitly states that it isn’t a product or a service . Instead, it is an approach based on principles such as verify explicitly , use least privilege access , and assume breach . That makes statement 2 true.

Statement 1 is false because Zero Trust does not require an Azure subscription. Microsoft provides Zero Trust guidance across many environments, including Microsoft 365, Copilot, Azure, and hybrid scenarios. It is a strategy that can be implemented with different technologies and is not dependent on owning Azure specifically.

Statement 3 is also false because there is no single switch in the Microsoft 365 admin center to “enable Zero Trust” for an organization. Microsoft’s documentation presents Zero Trust as a set of policies, configurations, and deployment steps across services such as Microsoft Entra, Intune, Defender, and Microsoft 365 workloads, not as one admin-center toggle.

Bottom of Form

The correct answer is A. the Microsoft Defender portal . Microsoft documents that phishing investigation and analysis for email threats is handled in Microsoft Defender for Office 365 through the Microsoft Defender portal . Microsoft’s phishing investigation guidance and email security reporting both point admins to Defender capabilities such as Threat Explorer , campaign views , and phish reports to understand the scope, affected users, and impact of phishing attacks.

The other options are not the primary investigation tool for this scenario. The Microsoft 365 admin center is mainly for tenant administration and usage reporting, not detailed phishing impact investigation. The Microsoft Entra admin center focuses on identity and access management, not email threat analysis. The Exchange admin center manages mail flow and Exchange settings, but Microsoft’s current phishing investigation workflows are centered in the Microsoft Defender portal , where security analysts can review detections, remediation actions, and affected recipients.

So, to review the impact of a phishing incident that targeted email users, the Microsoft-documented choice is the Microsoft Defender portal .

The correct answer is D. an app registration . Microsoft Learn states that to delegate identity and access management functions to Microsoft Entra ID , an application must be registered with a Microsoft Entra tenant . When you register an application, you create its identity configuration in Microsoft Entra, and a corresponding service principal is created so the application can authenticate and integrate with the tenant. This is the standard Microsoft mechanism for allowing a third-party cloud service or app to authenticate to Microsoft Entra.

The other options do not provide the app identity required for authentication. Multifactor authentication (MFA) strengthens user sign-ins, but it does not onboard a third-party service as an application identity in Entra. Conditional Access enforces access policies after authentication and authorization decisions are being made; it does not create the application identity itself. A Microsoft 365 Copilot connector is used to bring external data into Microsoft 365 experiences, not to let a third-party cloud service authenticate to Microsoft Entra. Therefore, the correct configuration is an app registration .

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.

Option A is incorrect because SharePoint site permissions are part of SharePoint content and collaboration security, not a direct factor in the Microsoft Entra Identity Secure Score model. Option D is also incorrect because the location of users can be used in Conditional Access and other access control decisions, but Microsoft does not list user geographic location itself as a direct Identity Secure Score recommendation. Identity Secure Score is driven by Entra identity best-practice checks and recommendations rather than by SharePoint permission structure or user location data.

The correct answer is Microsoft SharePoint sites . Microsoft Learn documents that Microsoft Purview sensitivity labels for containers can be applied to Microsoft Teams, Microsoft 365 groups, and SharePoint sites . These labels can control settings such as privacy, external sharing, and unmanaged device access for the labeled site. That is the official Microsoft feature that matches the sentence in the question.

The other options are not the best match for this item. Microsoft 365 Copilot conversations are not the standard object to which admins directly apply a sensitivity label in the way this question is asking. Copilot can honor labels on source content and may display label context in responses, but the selectable resource here is not “Copilot conversations.” Azure Blob Storage is also not the intended answer in the Microsoft 365 Copilot and Agent Admin context for Purview sensitivity labels.

So for this hotspot, the sentence is correctly completed with Microsoft SharePoint sites , because Microsoft explicitly supports applying Purview sensitivity labels to SharePoint sites as a container-level labeling capability.

time-bound role activation

The correct answer is time-bound role activation . Microsoft Learn explains that Microsoft Entra Privileged Identity Management (PIM) allows users to be made eligible for privileged roles and then activate those roles only when needed. Microsoft also states that once activated, the role is active for a preconfigured period of time , after which the privileged access expires automatically. This is the core just-in-time and time-limited access model that PIM is designed to provide. ( learn.microsoft.com )

The other options do not match Microsoft’s definition of PIM. It is not primarily described as providing restricted access to Microsoft 365 services , the lifecycle management of users , or the management of enterprise applications . Those areas relate more closely to other Microsoft Entra and Microsoft 365 governance capabilities. Microsoft specifically positions PIM as a service to manage, control, and monitor access to important resources by using eligible assignments , approval workflows , MFA if required , and temporary role activation . Therefore, the phrase that correctly completes the sentence is time-bound role activation . ( learn.microsoft.com )

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 .

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 .

The correct selections are No, No, Yes . Microsoft states that in Microsoft 365 Copilot and Microsoft 365 Copilot Chat, prompts and responses aren’t used to train the underlying foundation models . Microsoft also documents that Copilot works within the Microsoft 365 service boundary and that data accessed through Microsoft Graph isn’t used to train foundation models . That makes statements 1 and 2 No .

Statement 3 is Yes because Microsoft documents that Microsoft 365 Copilot honors the same data protection, access control, and compliance capabilities that apply across Microsoft 365. Microsoft also states that Copilot only surfaces organizational data that users already have permission to access, including content retrieved through Microsoft Graph in services such as SharePoint, OneDrive, Exchange, and Teams.

The correct answer is C. Site lifecycle management . In the SharePoint admin center, Microsoft includes a Site ownership policy under Site lifecycle management that can identify sites with too few owners and drive remediation. Microsoft documents that this policy can detect sites with fewer than the required number of owners, notify site owners, and if the issue is not fixed, enforce an action such as making the site read-only . That directly matches the requirement that sites with fewer than two owners be marked as read-only when they are not remediated.

The other options do not fit this scenario. Site-level access restriction is about controlling who can access a site, not enforcing ownership-count governance. Data access governance reports help identify oversharing and permissions exposure, but they do not enforce a minimum-owner remediation policy that makes sites read-only. Block download policy for SharePoint and OneDrive is used to restrict downloading from unmanaged devices or similar access scenarios, not to handle insufficient site ownership. Therefore, the Microsoft-documented feature to configure is Site lifecycle management .

The correct answer is C. Microsoft Graph . Microsoft documents that Microsoft 365 Copilot combines large language models with content and context from the Microsoft Graph to generate grounded responses. Microsoft Graph provides access to organizational data and signals across Microsoft 365 services, including SharePoint , OneDrive , Exchange , Teams , calendars, chats, files, and other work content. When SharePoint data is relevant to the prompt and the user already has permission to access it, Copilot uses Microsoft Graph as the layer that retrieves and grounds that corporate data for the response.

The other options are incorrect for this question. Microsoft Intune is used for endpoint and device management. Microsoft Defender is used for threat protection and security operations. Microsoft Purview provides compliance, governance, data protection, and risk management capabilities. While Copilot honors Purview protections and Microsoft 365 permissions, the specific service it uses to access and ground responses in SharePoint-based corporate data is Microsoft Graph . Therefore, the correct answer is Microsoft Graph .
