AB-900 Exam Dumps - Microsoft 365 Certified: Copilot and Agent Administration Fundamentals Questions and Answers

The correct answer is D. a sensitivity label policy . In Microsoft Purview, creating a sensitivity label by itself does not make it available to users. Microsoft Learn states that after you create sensitivity labels, you must publish them by creating a label policy so that users and groups can see and apply those labels in Microsoft 365 apps and services. Publishing controls which labels are available and to whom they are shown. This is why a sensitivity label policy is required to ensure that users can apply Label1 to files.

The other options do not meet the requirement. Auto-labeling policies apply labels automatically when content matches conditions, but they are not the primary mechanism for simply making a label available for user selection. A trainable classifier is used to identify content categories, not to publish a label. A retention label policy publishes retention labels for records and lifecycle purposes, which is different from sensitivity labeling for classification and protection. Therefore, the correct Microsoft-documented method to let users apply Label1 to files is to publish it using a sensitivity label policy .

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 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.

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 Microsoft Graph . Microsoft documents that Microsoft 365 Copilot accesses organizational content and context through Microsoft Graph . Microsoft Graph provides the user’s work context, including items such as emails, chats, meetings, files, contacts, and calendar data , along with relationship and activity signals that help Copilot ground and rank responses. Microsoft also explains that Copilot combines organizational content with the user’s working context, such as recent chat conversations, email exchanges on a topic, and the meeting the user is currently in. Those are exactly the kinds of signals described in the question, including collaboration history and document relevance.

The other options do not fit this sentence. Microsoft Copilot Studio is used to build and customize copilots and agents. Microsoft Purview is for compliance, governance, and data protection. Microsoft Viva Insights provides workplace analytics and insights, but it is not the core service described by Microsoft as supplying the contextual signals that ground Microsoft 365 Copilot responses. Therefore, the only option that correctly completes the sentence is Microsoft Graph .

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 answer is C. the code interpreter capability . Microsoft Learn states that the code interpreter capability for Microsoft 365 Copilot declarative agents allows the agent to generate and execute Python code to analyze data and generate visualizations . Microsoft’s agent schema documentation explicitly describes Code Interpreter as a capability used to solve complex math problems, analyze data, and generate visualizations. That directly matches the requirement to create charts and visualizations from a Microsoft Excel workbook .

Microsoft documentation also explains that code interpreter supports working with Excel files and is used for scenarios such as data analysis , statistical computations , and generating charts . This makes it the correct configuration for an agent that must reason over workbook data and produce chart-based outputs. By contrast, the image generator capability is for creating images, not for analyzing workbook data. The Scrum Assistant and Customer Insights Assistant options are templates, not the specific technical capability required to read data and build charts from an Excel workbook.

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 Microsoft Defender XDR . Microsoft Learn defines Microsoft Defender XDR as a unified pre- and post-breach enterprise defense suite that natively coordinates detection, prevention, investigation, and response across endpoints, identities, email, and applications to provide integrated protection against sophisticated attacks. That wording matches the sentence in the question almost exactly, which makes this the clearly correct choice.

The other options do not fit that definition. Microsoft Entra Conditional Access is Microsoft’s Zero Trust policy engine used to evaluate signals and enforce access policies, not a cross-domain threat detection and response suite. Microsoft Entra ID Protection focuses on detecting and responding to identity risks such as risky sign-ins and risky users. Microsoft Purview is Microsoft’s portfolio for data governance, data security, and compliance. None of those products is described by Microsoft as coordinating detection, prevention, investigation, and response across endpoints, identities, email, and applications in the same integrated XDR manner. Therefore, the only answer that correctly completes the sentence is Microsoft Defender XDR .

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.
