AB-900 Microsoft 365 Copilot & Agent Administration Fundamentals Study Prep

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 answer is C. Run the prompt. Scheduled prompts in Microsoft 365 Copilot are based on an existing Copilot prompt interaction. The practical workflow is to run the prompt first, then use the scheduling option for that prompt to define when and how often it should run, such as midnight. Saving a prompt is useful for reuse, but the question asks what task must be included to schedule a prompt execution. Creating an agent is a separate customization workflow and is not required to schedule a normal Copilot prompt. Creating a notebook is also unrelated; notebooks organize materials and chats but do not create a scheduled prompt run by themselves. The required action is to run the prompt so it can be scheduled.

To use Microsoft 365 Copilot Chat to reason over web data, you need a Microsoft 365 Copilot license. Answer: No

To use the Researcher agent in Microsoft 365 Copilot, you need a Microsoft 365 Copilot license. Answer: Yes

To add an agent in the Microsoft 365 Copilot app, you need a Microsoft 365 Copilot license. Answer: No

The correct selections are No, Yes, No . Microsoft documents that Microsoft 365 Copilot Chat is available at no additional cost for eligible Entra account users with qualifying Microsoft 365 licenses, and that it includes secure AI chat grounded in the web . That means a separate Microsoft 365 Copilot add-on license is not required just to use Copilot Chat over web data.

Statement 2 is Yes because Microsoft states that Researcher is part of the core default experience for Microsoft 365 Copilot licensed users . In other words, access to the Researcher agent requires the Microsoft 365 Copilot license.

Statement 3 is No because Microsoft documents that users can access agents and create them in the Microsoft 365 Copilot app through Copilot Chat, and Microsoft 365 service descriptions state that web-grounded agents are available at no extra cost for commercial users with a qualifying Microsoft 365 license. A Copilot add-on license is required for certain advanced capabilities, but not simply to add an agent in the app in general.

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.

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.

Communications Compliance uses OCR (optical character recognition) and machine learning to detect offensive or risky text inside images , including those in SharePoint and OneDrive.

By default, Communications Compliance pseudonymizes user identities to reduce investigator bias. Admins can later deanonymize if needed.

It does not add disclaimers. It silently monitors communications and flags policy violations; disclaimers are handled by Exchange transport rules, not Communications Compliance.

The correct answer is C because Microsoft explains that authorization is the process of determining whether an authenticated identity is allowed to access a resource . Microsoft Learn distinguishes authorization from authentication by stating that authentication proves who you are, while authorization decides what you can access or do after identity has been established. In Microsoft 365 and the Microsoft identity platform, authorization commonly involves permissions, scopes, roles, and consent that control access to data and services such as Microsoft Graph, Exchange, SharePoint, or Teams.

Option A is incorrect because it refers more to external identity validation or federation concepts, not authorization itself. Option B describes authentication , not authorization, since it is about verifying identity claims. Option D describes a control such as multifactor authentication or Conditional Access requirements, which can happen before access is granted, but that still is not the definition of authorization. Authorization begins after identity verification and focuses on whether the identity has the right permissions for the requested resource.

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.

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 .
