Microsoft AB-900 Dumps

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.

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 .

provide control over how users can access cloud apps.

The correct answer is provide control over how users can access cloud apps . Microsoft Learn defines Microsoft Entra Conditional Access as the Zero Trust policy engine that uses if-then logic to make access decisions. Microsoft states that Conditional Access policies determine who can access resources, what resources they can access, and under what conditions . These policies can require actions such as multifactor authentication, compliant devices, or other controls before allowing access to applications and services like Microsoft 365. That means Conditional Access is specifically used to control how users access cloud apps .

The other options are incorrect. Conditional Access policies are not configured by using the Microsoft Defender portal ; they are managed in the Microsoft Entra admin center . They are also not applied only to on-premises resources , because Microsoft documents Conditional Access primarily for cloud identities, cloud apps, and cloud-connected resources. Finally, Conditional Access does not require a Microsoft Exchange mailbox. It can be applied broadly across many Microsoft and third-party cloud applications integrated with Microsoft Entra.

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 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 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.

Prevent users from sharing PII: Data Loss Prevention

Use machine learning to train a model: Information Protection

The correct selections are Data Loss Prevention and Information Protection . Microsoft states that Microsoft Purview Data Loss Prevention (DLP) helps organizations identify, monitor, and automatically protect sensitive information, including preventing people from sharing sensitive items such as PII in Microsoft 365 locations and other supported channels. That directly matches the requirement to stop users from sharing files that contain personally identifiable information.

For the second requirement, the correct choice is Information Protection because Microsoft Purview’s classification and labeling capabilities include trainable classifiers , which Microsoft describes as a tool you can train using machine learning to recognize types of sensitive or business content. Microsoft positions these classification capabilities under Microsoft Purview Information Protection and data classification. That makes Information Protection the best fit for “use machine learning to train a model that detects sensitive content.”

The other options are not the best match here. Communication Compliance monitors risky communications, DSPM for AI focuses on AI posture and exposure, and Insider Risk Management detects risky user behavior rather than blocking PII sharing or training classifiers.

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 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 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 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.

You can use the eDiscovery Microsoft Purview solution to find all the content that relates to the term “Project Falcon” in the emails exchanged by two users.

The correct answer is eDiscovery . Microsoft documents that Microsoft Purview eDiscovery is used to search for content in Microsoft 365 data sources that is relevant to an investigation, legal matter, or internal review. Microsoft specifically states that eDiscovery search can find email messages, documents, instant messages, and other content across Microsoft 365 locations, including Exchange Online mailboxes . This makes it the correct solution for locating content related to a keyword or phrase such as “Project Falcon” in emails exchanged between specific users.

This is different from other Purview solutions such as Communication Compliance, which is designed to monitor risky or inappropriate communications, or Data Lifecycle Management, which is for retention and deletion. The requirement here is targeted search and retrieval of content connected to a specific term in user email communications, which is exactly what eDiscovery is designed to do. Microsoft also notes that eDiscovery supports keyword queries and search conditions , which further aligns with this scenario.

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 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.

You can use a Microsoft Entra security group to assign permissions to Microsoft Entra ID resources. Answer: Yes

You can use a Microsoft Entra security group to assign Microsoft 365 licenses. Answer: Yes

You can use a Microsoft Entra security group to assign permissions to Microsoft Exchange mailboxes. Answer: No

The correct selections are No, Yes, Yes . Statement 1 is No because Microsoft documents tenant controls for web search on or off , but not a general Microsoft 365 Copilot setting to block only selected websites for normal Copilot responses. Microsoft also says it doesn’t recommend or support managing Copilot through selective URL or domain blocking at the network level. Website allow/block lists shown in Microsoft documentation apply to Researcher with Computer Use virtual-device settings, not to standard Microsoft 365 Copilot web grounding overall.

Statement 2 is Yes because Microsoft provides the Allow web search in Copilot policy in Cloud Policy service and in the Microsoft 365 admin center, which can disable web search for Microsoft 365 Copilot and Copilot Chat.

Statement 3 is Yes because Microsoft states that admins can block Researcher and Analyst , and agent governance includes a Block action. Microsoft also notes that for Researcher and Analyst, user scoping isn’t edited through the usual panel; availability is managed by blocking the selected agent at the tenant level.

The correct answer is Connectors . Microsoft documents that Microsoft 365 Copilot connectors are used to bring external, line-of-business data into Microsoft 365 Copilot so users can search, reason over, and act on content from non-Microsoft systems. Microsoft also states that admins must enable and configure Copilot connectors in the Microsoft 365 admin center , and once configured, those connectors can be selected as knowledge sources for custom agents. This directly matches the requirement to let users use an external system as a knowledge source for custom Microsoft 365 Copilot agents.

This is why the hotspot in the Copilot area should be set to Connectors , not Overview, Agents, Search, Billing & usage, or Settings. Overview provides status information, Agents is for agent management, Search is for Microsoft Search experiences, and Billing & usage is for metering and consumption tracking. The specific admin feature that enables external enterprise data sources for agent grounding is Connectors . Microsoft further explains that configured connectors can expose external knowledge securely and respect source-level permissions when used in agent scenarios.

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 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 D. From the Finance site, configure permissions . Microsoft states that Microsoft 365 Copilot honors existing Microsoft 365 permissions and only grounds responses in content that the signed-in user is already allowed to access. That means if users are getting Finance-site content in Copilot responses, those users likely still have permission to that SharePoint content. The direct fix is to review and correct the site, library, folder, or file permissions on the Finance site so only the intended users retain access.

The other options do not directly solve this requirement. Information Barriers are designed for communication and collaboration segmentation scenarios, not for ordinary site-level oversharing remediation. A Defender data connector is unrelated to SharePoint permission enforcement. Conditional Access controls sign-in and session access conditions, but it does not selectively remove Copilot grounding from one SharePoint site for users who still have site permissions. Because Copilot uses SharePoint and Microsoft Graph permissions as its boundary, the Microsoft-documented corrective action is to fix the Finance site permissions .
