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

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 B. the Microsoft 365 admin center . Microsoft documents that administrators assign product licenses to users from the Microsoft 365 admin center , including on the Active users page where you can open a user account and manage Licenses and apps . Microsoft also documents license assignment workflows there for both direct assignment and group-based licensing scenarios. That makes the Microsoft 365 admin center the standard administrative portal for giving a user access to Microsoft 365 services and features.

The other options are incorrect for this task. The Microsoft Purview portal is used for compliance, governance, data protection, eDiscovery, audit, and related Purview solutions, not for assigning Microsoft 365 product licenses. The Microsoft Teams admin center is used to manage Teams settings, policies, devices, voice, and collaboration features, but it is not the central portal for assigning tenant product licenses to users.

Therefore, when the requirement is simply to assign a license to a user in a Microsoft 365 subscription, Microsoft’s documented answer is the Microsoft 365 admin center .

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 Information Protection and Data Loss Prevention . Microsoft documents that Microsoft Purview Information Protection helps organizations discover, classify, protect, and govern sensitive information wherever it lives or travels . Microsoft also describes Information Protection as the Purview solution for data classification, sensitivity labels, and encryption , including scenarios across Microsoft 365, on-premises repositories, cloud stores, and even third-party apps through supported extensions. That makes it the correct choice for the requirement to discover and classify sensitive data across multiple platforms .

For the second requirement, Microsoft states that Microsoft Purview Data Loss Prevention (DLP) helps prevent the unintentional sharing of sensitive items and can block users from prohibited activities , including inappropriate external sharing through services such as SharePoint, OneDrive, Teams, and email. Microsoft specifically documents DLP scenarios for preventing sensitive items from being shared with external users , which matches the requirement to block users from sharing intellectual property externally.

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.

The correct selections are No, Yes, Yes . Statement 1 is No because Microsoft documents that Agent Builder in Microsoft 365 Copilot is included with the Microsoft 365 Copilot license , and agents built with that feature are part of that licensed experience. Microsoft also states that the capability is enabled by default in Microsoft 365 Copilot licensed tenants . While Copilot Chat users with qualifying Microsoft 365 licenses can access web-grounded chat experiences, creating Microsoft 365 Copilot agents in the app is documented under the Copilot-licensed Agent Builder experience, not as an E5-only entitlement.

Statement 2 is Yes because Microsoft states that Researcher and Analyst were deployed to users with Microsoft 365 Copilot licenses . Statement 3 is Yes because Microsoft says users can build agents in Agent Builder by using natural language or manually .

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 A . Microsoft Learn defines Zero Trust as a security strategy built on the principles verify explicitly , use least privilege access , and assume breach . Microsoft also summarizes Zero Trust as a model that assumes breach and verifies every request , rather than trusting users, devices, or traffic simply because they originate from inside the corporate network. This is the key reason option A is correct. Under Zero Trust, every access request should be evaluated continuously using available signals such as identity, device state, location, service, and risk.

Option B is incorrect because improving user experience is not the defining principle of Zero Trust. Option C is incorrect because Zero Trust requires ongoing review and adjustment of permissions, especially through least privilege and risk-based access. Option D is incorrect because Zero Trust explicitly rejects implicit trust based on network location. Microsoft states that organizations should reduce reliance on the traditional idea that anything on the internal network is automatically safe or trustworthy.

A Communication Compliance policy can detect inappropriate text in Microsoft Teams messages. Answer: Yes

A Communication Compliance policy can detect offensive language in Microsoft 365 Copilot prompts. Answer: Yes

A Communication Compliance policy can be used to retain email messages for 10 years. Answer: No

The correct selections are Yes, Yes, No . Microsoft documents that Microsoft Purview Communication Compliance can detect potentially inappropriate messages in supported communication channels, including Microsoft Teams and email . Microsoft also states that reviewers can investigate communications in Microsoft 365 Copilot and Microsoft 365 Copilot Chat , which means Communication Compliance policies can evaluate Copilot prompts and responses for risky or offensive content.

This makes statement 1 Yes , because inappropriate text in Teams messages is a standard Communication Compliance scenario. Statement 2 is also Yes , because Microsoft explicitly includes Microsoft 365 Copilot and Microsoft 365 Copilot Chat among the supported communication sources for policy review and investigation.

Statement 3 is No because retaining email for a fixed period such as 10 years is handled by Microsoft Purview Data Lifecycle Management through retention policies or retention labels, not by Communication Compliance. Communication Compliance is for monitoring and investigating risky communications, not for long-term retention enforcement.

The correct selections are No, No, Yes . Microsoft states that for Microsoft 365 Copilot , customer prompts, responses, and Microsoft Graph grounding data aren’t used to train foundation models . Microsoft also explains that Copilot processes organizational data within the service boundary and applies the same commitments that protect Microsoft 365 customer data. That makes statements 1 and 2 No . Microsoft further documents that Microsoft 365 Copilot grounds responses using Microsoft Graph and only surfaces data that the user is permitted to access , so it respects existing identity, access, and permission controls in the tenant. That makes statement 3 Yes .

This behavior is a core part of Copilot’s enterprise design. Microsoft describes Copilot as inheriting your organization’s existing Microsoft 365 permissions model, including access controls on content in SharePoint, OneDrive, Exchange, Teams, and other Microsoft 365 services. So Copilot does not grant new access; it works within the permissions already assigned to the signed-in user.

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 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 selections are No, Yes, Yes . Microsoft documents that the Audit page in the Microsoft Defender portal can be used to search the unified audit log for user and admin actions in the organization. Microsoft also states that audit log search in the Defender portal is the same as audit log search in the Microsoft Purview portal , which means both portals can be used to review administrative actions taken in Microsoft 365.

Microsoft further explains that Microsoft Purview Audit enables organizations to search for audit records of activities that users and admins perform across Microsoft services, making it a correct tool for this requirement.

By contrast, Search & intelligence in the Microsoft 365 admin center is not the feature used to investigate administrator actions through the unified audit log. It is not Microsoft’s documented audit search tool for this purpose. Therefore, for this hotspot the right answers are No for Search & intelligence, Yes for Audit in Microsoft Defender, and Yes for Audit in Microsoft Purview.

The correct answer is A. Microsoft Entra ID Protection . Microsoft Learn explains that Microsoft Entra ID Protection detects sign-in risk and user risk and can work with Conditional Access risk policies to automatically respond when suspicious authentication activity is identified. Microsoft documents specifically state that organizations can configure sign-in risk policies and user risk policies to automate responses such as blocking access , requiring multifactor authentication , or forcing password changes when risky activity is detected. Microsoft also notes that some very high-confidence risky sign-ins are automatically blocked by built-in protections.

The other options do not match this function. Microsoft Defender for Office 365 focuses on email, collaboration, and threat protection for tools like Exchange Online and Teams, not sign-in risk blocking. Microsoft Entra Privileged Identity Management (PIM) manages privileged role activation and governance, not risky sign-in detection. Microsoft Defender for Identity detects identity-related threats in hybrid identity environments, but the Microsoft feature used to automatically block risky sign-ins is Microsoft Entra ID Protection .

The correct answer is D. the Analyst agent in Microsoft 365 Copilot . Microsoft Learn training for Microsoft 365 Copilot specifically distinguishes the Analyst agent as the tool for gathering insights from data and enhancing data presentations. Microsoft’s guidance also notes in the Researcher FAQ that when the task is spreadsheet-related , Analyst agent is better suited for Microsoft Excel related tasks . This makes Analyst the best choice for a quarterly sales reporting scenario that involves detecting performance trends , surfacing anomalies , and producing visual insights from multiple datasets.

The other options are less suitable. Researcher is intended for complex multi-step research and source-cited reports across web and work content, not specialized data analysis across files. Microsoft 365 Copilot Search is for finding information, not for deep quantitative analysis and anomaly summarization. Copilot in Excel is powerful for workbook-level analysis, but the question emphasizes broader insight generation across multiple files and asks for the best Copilot experience for trends, visuals, and anomaly summaries. Microsoft positions Analyst as the dedicated agent for that kind of data-analysis workflow.

The correct answer is C. a custom Microsoft 365 Copilot agent . Microsoft Learn explains that Agent Builder in Microsoft 365 Copilot lets you create agents with specific instructions , dedicated knowledge sources , and starter prompts . Starter prompts are designed to help users understand the most common supported scenarios, which directly matches the requirement to provide users with a list of common queries. Microsoft also documents that an agent can be grounded in selected SharePoint sites, folders, or files , allowing the response scope to be targeted to the HR policy content in Site1 rather than broad enterprise or web data.

The other options do not fit the requirement. Copilot in Word is document-focused and is not intended to create a reusable, shared query experience grounded only in one SharePoint source. Copilot notebooks group materials and chats, but they are not the right tool for publishing a guided HR policy assistant with starter prompts. Researcher is designed for broader, multi-step research using work data and web content, so it does not satisfy the requirement to keep answers grounded only in Site1.

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 selections are Yes, No, Yes . Microsoft states that Microsoft 365 Copilot inherits the security, compliance, and privacy policies already configured in Microsoft 365, including Microsoft Purview sensitivity labels and other compliance controls. That makes statement 1 Yes . Microsoft also explains that Copilot respects existing access controls and compliance boundaries rather than bypassing them.

Statement 2 is No because Microsoft 365 Copilot does not ignore Microsoft Purview DLP . Microsoft documents that Copilot honors the protections applied to the underlying content and works within Microsoft 365’s existing compliance framework. DLP remains part of the environment governing how sensitive data is protected and shared.

Statement 3 is Yes because Microsoft clearly states that Copilot only surfaces content that a user is already authorized to access through existing Microsoft 365 permissions . Copilot uses Microsoft Graph to ground responses, but it does not grant new permissions or expose content outside the user’s allowed scope. Therefore, the correct hotspot answers are Yes , No , and Yes .
