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

The correct selections are The Microsoft 365 admin center and A billing policy . Microsoft documents that Microsoft 365 Copilot pay-as-you-go is administered in the Microsoft 365 admin center , specifically under Copilot > Billing & usage , where admins create and manage billing policies . Microsoft explains that a billing policy defines the billing infrastructure for pay-as-you-go, including the Azure subscription and the set of users covered by that policy. That user scoping is what allows organizations to separate usage and spending by groups such as departments.

Microsoft also documents that billing policies support budgets , spending views , and monitoring current expenses for services linked to the policy. This supports the requirement for greater visibility into Copilot usage costs and forecasting departmental spending. By assigning different departments to different billing policies, the organization can track Copilot costs by department. The other listed features do not fit: auto-claim policy is unrelated to cost tracking, and Copilot connector is for external data grounding, not billing segmentation.

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 answers are A and D because both tasks are supported directly in the Exchange admin center (EAC) . Microsoft Learn states that administrators can manage mail flow rules in Exchange Online from the EAC under Mail flow > Rules , which includes creating and managing transport rules for organizational email handling. Microsoft Learn also states that administrators can create shared mailboxes in the EAC under Recipients > Mailboxes , where a shared mailbox can be added and then delegated to users.

Option B is incorrect because adding a custom domain is normally done in the Microsoft 365 admin center , specifically on the Domains page. Although Exchange can later work with accepted domains and related mail flow settings, the act of adding and verifying a custom domain is not an Exchange admin center task. Option C is incorrect because license assignment is handled through Microsoft 365 or Microsoft Entra administrative tools, not the Exchange admin center.

The correct answer is D. Data Lifecycle Management . Microsoft Learn states that Microsoft Purview retention policies and retention labels, managed under Data Lifecycle Management , support three core outcomes: retain-only , delete-only , and retain and then delete . The requirement in this question is exact: keep email for seven years and then permanently delete it. That is a textbook retain and then delete retention configuration, which Microsoft documents as part of Purview’s retention capabilities. Microsoft also recommends using Microsoft 365 retention policies and labels for retaining and deleting emails rather than relying on older Exchange-only approaches in most modern compliance scenarios.

The other options do not meet the requirement. Information Protection focuses on labeling and protecting sensitive information. Insider Risk Management is used to detect and investigate risky user behavior. Data Loss Prevention helps prevent inappropriate sharing or exfiltration of sensitive data. None of those are designed to enforce a timed seven-year retention period followed by automatic permanent deletion. The Microsoft Purview solution explicitly built for that lifecycle requirement is Data Lifecycle Management .

The correct answers are C and D . Microsoft Learn explains that agents created with Agent Builder in Microsoft 365 Copilot allow you to define specific instructions that extend Microsoft 365 Copilot for a business scenario. Microsoft also documents that you can add knowledge sources such as specific public websites and SharePoint content so the agent can reason over targeted information instead of relying only on the default chat experience. Those two capabilities directly match the needs in options C and D.

Option A is incorrect because grouping chats is a Copilot notebook scenario, not the reason to build an agent. Option B is incorrect in the context of creating an agent in the Microsoft 365 Copilot app . Agent Builder supports declarative agents with instructions, knowledge, and capabilities, but Microsoft Learn describes custom AI model control as part of custom engine agents built with tools such as Copilot Studio, SDKs, or Foundry, not as a standard Agent Builder feature in the Microsoft 365 Copilot app. Therefore, when the task is specifically to create an agent in the app, the valid reasons are custom instructions and reasoning over a specific website .

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.

a site member of

The correct answer is a site member of . In the exhibit, the Site members group for Site1 contains Everyone except external users with Edit permissions. Microsoft documents that “Everyone except external users” automatically includes all internal users and excludes external guests . Since User1 is a newly created user in the organization, User1 is an internal user and is therefore included in that built-in principal.

Because that built-in principal is placed in the Site members group, User1 inherits member-level access to the site. User1 is not a site owner, because the Site owners group contains only the Global Administrator entry shown in the exhibit. User1 is also not merely a visitor, because the Site visitors group is listed as None . Finally, User1 is not prevented from accessing the site, because the membership granted through Everyone except external users gives internal users access to the site according to the permissions assigned to that group.

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.

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 Microsoft Authenticator app

The correct answer is the Microsoft Authenticator app . The image shows the familiar Microsoft MFA prompt that says “Are you trying to sign in?” and “Enter the number shown to sign in.” Microsoft documents this as number matching in Authenticator push notifications , which is part of Microsoft Entra multifactor authentication using the Microsoft Authenticator app . Microsoft explains that number matching is a security improvement for Authenticator push approvals and is used when the default sign-in method is Authenticator push notifications.

The other choices do not match the experience shown. Email OTP would involve a one-time code sent by email. SMS would send a text message code to a phone number. Temporary Access Pass is a time-limited passcode used for onboarding or recovery scenarios, not the mobile push screen shown in the image. Because the graphic specifically shows a mobile approval prompt with number matching, the MFA method is clearly the Microsoft Authenticator app .

The correct answer is accountability . Microsoft’s Responsible AI framework is built on six principles: fairness , reliability and safety , privacy and security , inclusiveness , transparency , and accountability . Microsoft describes accountability as the principle that people who design and deploy AI systems must remain responsible for how those systems operate and for the impacts they create. A key part of that principle is ensuring there is human oversight so humans remain in control of decisions and system behavior.

The other options do not match the wording in the sentence as closely. Transparency focuses on helping people understand how AI systems work and why they produce certain outcomes. Privacy and security is about protecting data and securing systems. Reliability and safety is about dependable and safe operation. Inclusiveness is about designing AI that empowers and includes people broadly. The principle tied to oversight, responsibility, and keeping humans in control is accountability .

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 .

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 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 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 .

The correct answer is eDiscovery . In Microsoft Purview, eDiscovery is the solution used to search for content and export copies of that content from Microsoft 365 locations such as SharePoint and OneDrive. Microsoft Learn states that when you export search results from eDiscovery, copies of native Office documents and other documents are exported . That directly matches the requirement to provide HR with a copy of files .

By contrast, Audit is primarily used to investigate user and admin activity records and can export those audit records to CSV , but it does not export the actual files themselves. Audit would help identify that User1 modified files, but the question asks for copies of the recent files modified by User1 , which is an eDiscovery content search and export scenario rather than an activity-log reporting scenario.

So, among the Microsoft Purview solutions shown, the appropriate selection is eDiscovery because it is the Purview tool designed to find and export the actual content items HR wants to receive.

Microsoft Defender for Office 365 provides protection from phishing and malware attacks. Answer: Yes

Microsoft Defender for Identity monitors identities in Active Directory domains. Answer: Yes

Microsoft Defender Vulnerability Management provides protection for software as a service (SaaS) applications. Answer: No

The correct selections are Yes, Yes, No . Microsoft documents that Microsoft Defender for Office 365 protects email and collaboration workloads from threats such as phishing and malware , including zero-day malware and business email compromise scenarios. That makes statement 1 Yes .

Statement 2 is also Yes because Microsoft states that Microsoft Defender for Identity monitors identity signals from on-premises Active Directory and related identity infrastructure to detect suspicious activity and identity-based attacks. Microsoft further describes monitoring information generated from your organization’s Active Directory, network, and event activities.

Statement 3 is No because Microsoft Defender Vulnerability Management is focused on discovering and prioritizing vulnerabilities across devices and assets such as Windows, macOS, Linux, mobile platforms, and network devices. Microsoft’s SaaS application protection offering is Microsoft Defender for Cloud Apps , not Defender Vulnerability Management.

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.
