Microsoft AB-100 Online Questions & Answers

• Question 71:

  A business team asks whether to build a custom AI component, buy a prebuilt capability, or extend an existing Microsoft agent. The use case is common across sales teams and already maps closely to Microsoft 365 Copilot for Sales capabilities, with only minor extra data needed from a partner application.

  What should you recommend?

  A. Build a custom model from scratch before evaluating existing products.
  B. Extend the existing sales Copilot experience with the partner data where needed.
  C. Replace Dynamics 365 Sales with a spreadsheet-based process.
  D. Avoid ROI analysis because prebuilt agents never have operating costs.
  B. Extend the existing sales Copilot experience with the partner data where needed.

  ---

  Explanation

  Extending the existing sales Copilot experience is best when the use case is common across sales teams and already maps closely to Microsoft 365 and Dynamics 365 sales workflows. Buying or building a completely custom component would add cost and complexity before proving that the standard experience cannot be extended. Extensibility keeps users in the tools they already use. The build-versus-buy rule is to extend first when the Microsoft product already fits most of the scenario.

• Question 72:

  DRAG DROP

  A company has an AI solution that uses a Microsoft Copilot Studio agent.

  You need to monitor the agent's performance. The solution must meet the following requirements: Monitor the agent's telemetry in near-real-time (NRT).

  Download transcripts of full conversations.

  Monitor the agent's usage and performance.

  What should you use for each requirement? To answer, drag the appropriate options to the correct requirements. Each option may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

  NOTE: Each correct selection is worth one point.

  The completed drag-and-drop maps near-real-time telemetry to Application Insights, transcript download to Microsoft Power Apps, and usage and performance monitoring to Copilot Studio. The answer image uses Application Insights for detailed telemetry, Copilot Studio for built-in analytics, and the app surface for transcript access in this scenario. Application Insights is the monitoring sink for operational events, while Copilot Studio provides native dashboards for usage and performance. The visual answer separates telemetry, transcript access, and aggregate monitoring instead of treating them as one feature.

• Question 73:

  A sales organization uses Copilot in Dynamics 365 Sales. Sellers ask Copilot for summaries of leads and opportunities. The security team wants assurance that sellers do not receive information from records they cannot access.

  Which design principle applies?

  A. Copilot summaries should ignore Dynamics 365 security roles to improve productivity.
  B. Copilot should be trained on exported CRM data outside Dynamics 365.
  C. Copilot can retrieve information only from records and files the signed-in user can access.
  D. Copilot must be disabled for all users who have access to SharePoint.
  C. Copilot can retrieve information only from records and files the signed-in user can access.

  ---

  Explanation

  Copilot in Dynamics 365 Sales respects the signed-in user's access to records and files. The seller should only receive information from data the user is already permitted to access. This permission trimming is essential for security because sales records often contain sensitive customer information. The design should rely on the product permission model rather than exposing a broader shared data source.

• Question 74:

  A company uses multiple Microsoft Copilot Studio agents across different channels.

  You need to recommend a monitoring solution that provides comprehensive telemetry data and performance insights for the agents.

  What should you include in the recommendation?

  A. Application Insights
  B. Microsoft Dynamics 365 Customer Voice
  C. Log Analytics
  D. Microsoft Purview
  A. Application Insights

  ---

  Explanation

  Application Insights is the monitoring solution for detailed telemetry and performance insight across Copilot Studio agents and channels. It supports centralized analysis of events, traces, and operational behavior. Customer Voice captures survey feedback, Log Analytics can store logs but is not the agent instrumentation choice by itself, and Purview focuses on governance. For comprehensive agent telemetry, use Application Insights.

• Question 75:

  A company wants a model selection strategy that can route requests to suitable underlying models while helping architects balance cost, performance, and compliance. The company also wants to monitor the cost of the routed requests.

  What should you recommend?

  A. A separate manually selected model for every prompt with no routing layer
  B. A Copilot Studio file group
  C. A SharePoint knowledge source
  D. A Microsoft Foundry model router deployment
  D. A Microsoft Foundry model router deployment

  ---

  Explanation

  A Microsoft Foundry model router deployment fits a strategy that routes requests to suitable underlying models while balancing cost, performance, and compliance. It centralizes model selection rather than hard-coding one model in every client. The same design also enables cost and usage monitoring across routed model calls. Use a router when the architecture needs policy-based model choice and operational visibility.

• Question 76:

  HOTSPOT

  You are designing an AI strategy for Microsoft Dynamics 365 finance and operations apps. You are evaluating the use of Microsoft Copilot Studio to provide in-app help and guidance based on generative AI general knowledge.

  You need to recommend which knowledge sources to include in the generative help and guidance agent. The solution must minimize the risk of generating inaccurate responses.

  What should you recommend? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

  ---

  The completed hotspot states that custom knowledge sources must be uploaded to the agent and AI general knowledge must be disabled. The answer image reflects an in-app help and guidance strategy that limits the agent to approved company content. Uploaded custom sources provide the organization's procedures, and disabling general knowledge reduces unsupported answers that are outside those sources. This is the safer pattern for regulated finance and operations help content.

• Question 77:

  A company has Microsoft Foundry agents that generate responses by using Azure OpenAI resources. The agents are deployed to both the United States and Europe.

  A company mandate states that the agents and their grounding data must adhere to data residency and movement regulations.

  You need to recommend a governance solution for the agents.

  What should you include in the recommendation?

  A. Microsoft Defender for Cloud
  B. Azure Policy
  C. Azure Monitor
  D. Microsoft Purview
  D. Microsoft Purview

  ---

  Explanation

  Microsoft Purview is the governance choice for data residency and data movement concerns because it provides data governance, classification, compliance, and audit capabilities across the estate. Azure Monitor observes resources, Defender focuses on security posture, and Azure Policy can enforce resource configuration, but Purview is the broader data governance service. The mandate is about grounding data and regulatory movement, so the data governance layer matters most. Use Purview when the question emphasizes data compliance rather than only resource health.

• Question 78:

  Note: This section contains one or more sets of questions with the same scenario and problem. Each question presents a unique solution to the problem. You must determine whether the solution meets the stated goals. More than one solution in the set might solve the problem. It is also possible that none of the solutions in the set solve the problem.

  After you answer a question in this section, you will NOT be able to return. As a result, these questions do not appear on the Review Screen.

  A company uses Microsoft 365 and Dynamics 365.

  You need to recommend a solution to automatically summarize email threads, generate suggested replies in Microsoft Outlook, and provide meeting preparation summaries that include relevant customer relationship management (CRM) data.

  Solution: You recommend a classic Microsoft Dataverse workflow.

  Does this meet the goal?

  A. Yes
  B. No
  B. No

  ---

  Explanation

  A classic Dataverse workflow does not meet the goal because it automates Dataverse record operations, not Outlook email summarization, suggested replies, or meeting preparation with CRM context. The requested capabilities are generative sales-assistance experiences in Microsoft 365. Even if a workflow can trigger backend actions, it cannot replace Copilot for Sales in Outlook and Teams. Use the embedded sales copilot rather than classic workflow automation for this scenario.

• Question 79:

  A Microsoft Foundry agent must answer from a private search index and also invoke serverless business logic to update a downstream system.

  Which two Foundry Agent Service tool types should you include? Each correct answer presents part of the solution.

  A. Azure AI Search
  B. Azure Functions
  C. Microsoft Planner labels
  D. SharePoint page templates
  E. Viva Engage communities
  A. Azure AI Search
  B. Azure Functions

  ---

  Explanation

  Azure AI Search provides the private retrieval index, and Azure Functions provides serverless business logic that the Foundry agent can call as a tool. These two tool types match the two requirements: answer from private search content and update a downstream system. A model alone cannot retrieve private indexed content or perform the update safely. Foundry agents combine retrieval tools and action tools to complete multi-step tasks.

• Question 80:

  HOTSPOT

  A company deploys a Microsoft Copilot Studio agent that integrates with a Microsoft Power Automate desktop flow.

  You need to recommend a testing solution that meets the following requirements:

  1. Test cases must validate the most recent changes to the agent before the agent is released.

  2. The flow must be validated as part of the agent's orchestration.

  What should you recommend for each requirement? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

  ---

  The completed hotspot should run tests against the latest unpublished version of the agent and add the desktop flow to the agent as a tool when validating orchestration. The visual answer area is about pre-release testing, so testing live users or production would be too late. The flow must be exercised through the agent path to validate orchestration, not only from the desktop-flow console in isolation. For release testing, validate the unpublished agent and the tool call together.
