The Microsoft 365 Copilot and Agent Administration Fundamentals (AB-900)

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 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.

The correct answer is A. Data access governance in the SharePoint admin center . Microsoft Learn documents Data access governance reports in the SharePoint admin center as the reporting solution used to understand data exposure, including permission structure and sharing link activity . Microsoft specifically states that the site permissions snapshot report provides visibility across SharePoint and OneDrive sites , helping administrators understand current permissions exposure, and that separate reports are created for SharePoint and OneDrive . Microsoft also documents sharing links activity reports as part of Data access governance for monitoring link-sharing activity, and notes that OneDrive support is available through PowerShell for those reports. Together, this is the Microsoft reporting capability aligned with permissions and active sharing links for OneDrive content.

The other options do not fit this requirement. Microsoft 365 admin center reports focus mainly on usage and activity reporting, not detailed permissions and sharing-link governance. Defender Audit is for security investigation activity, and Purview eDiscovery is for legal and investigative content search, not for generating OneDrive permissions and sharing-link governance reports. Therefore, the best Microsoft-documented answer is Data access governance in the SharePoint admin center .

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 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 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 answers are A and D because Microsoft Entra Identity Secure Score is based on identity security recommendations, and Microsoft Learn specifically lists recommendations such as “Designate more than one Global Administrator” and “Do not expire passwords.” That means the number of global administrators in the tenant and whether password expiration is disabled directly influence the Identity Secure Score. Microsoft also notes that the score measures how closely an organization aligns with Microsoft’s recommended identity security best practices.

Option B is incorrect because SharePoint site permissions are related to SharePoint and Microsoft 365 workload permissions, not to the Entra identity-focused scoring model. Option C is incorrect because user location may be evaluated in Conditional Access and Zero Trust scenarios, but it is not itself listed as a direct Identity Secure Score factor in the Microsoft Entra recommendations referenced by Microsoft Learn. Identity Secure Score is driven by tracked identity recommendations and security configurations, not by simple geographic placement of users.
