Question 1
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 has a team that analyzes its customers by using a manual process.
You are designing an AI-based agent to automate and improve the process.
You need to recommend on which platform to build the agent. The solution must meet the following requirements:
• Use generative AI to answer common questions.
• Provide analytics to review AI performance.
• Identify customer demographics.
• Minimize custom development.
Solution: You recommend Microsoft Copilot Studio.
Does this meet the goal?
A. Yes
B. No
Show Answer
Correct Answer: A
Explanation: Microsoft Copilot Studio is a low-code platform for building generative AI agents, includes built-in analytics for bot performance, and can connect to Microsoft Dataverse, Microsoft Fabric, Power Platform, and other data sources to retrieve and use customer demographic information with minimal custom development.
Question 1
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. the Analytics tab in Copilot Studio
B. Azure Advisor
C. Log Analytics
D. Microsoft Purview
Show Answer
Correct Answer: C
Explanation: Log Analytics provides a centralized place to query and analyze telemetry across multiple agents, including performance data and errors. The Copilot Studio Analytics tab is more limited to built-in agent analytics; Azure Advisor and Microsoft Purview do not provide this monitoring capability.
Question 2
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. Azure Advisor
B. Microsoft Dynamics 365 Customer Voice
C. Application Insights
D. Log Analytics
Show Answer
Correct Answer: C
Explanation: Application Insights provides comprehensive telemetry and performance monitoring for Copilot Studio agents, including data that can be used to analyze agent activity across channels and diagnose performance issues.
Question 3
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.

Solution: You recommend Microsoft Security Copilot.
Does this meet the goal?
A. Yes
B. No
Show Answer
Correct Answer: B
Explanation: Microsoft Security Copilot is designed to assist cybersecurity professionals with security operations. It is not the appropriate platform for building a customer analysis AI agent that uses generative AI for common customer questions, identifies customer demographics, provides AI performance analytics for business agents, and minimizes custom development. Platforms such as Microsoft Copilot Studio combined with AI services are better suited to those requirements.
Question 3
A company has an AI agent that automates the review of customer feedback stored in a cloud database.
You plan to generate monthly reports from the agent's output to provide insights into customer sentiment and guide product development and marketing.
You need to ensure that the data ingested by the agent is clean and suitable for the intended use.
What should you do to prepare the data?
A. Identify and address biased data.
B. Ensure that the size of the database does not exceed 100 GB.
C. Verify data privacy and security compliance.
D. Translate the data into a single language.
Show Answer
Correct Answer: A
Explanation: Identify and address biased data so the agent’s sentiment analysis is representative and reliable. Database size is not a measure of data quality, while privacy compliance and translation address other concerns and are not universally required for this use case.
Question 4
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.

Solution: You recommend GitHub Copilot.
Does this meet the goal?
A. Yes
B. No
Show Answer
Correct Answer: B
Explanation: GitHub Copilot is an AI coding assistant for software development, not a platform for building customer-facing AI agents. It does not provide built-in conversational agent capabilities, AI performance analytics, or customer demographic analysis. It also does not minimize development for this scenario compared to dedicated AI agent platforms such as Microsoft Copilot Studio.
Question 4
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. Azure DevOps
B. Microsoft Power BI
C. Microsoft Dynamics 365 Customer Voice
D. Application Insights
Show Answer
Correct Answer: D
Explanation: Application Insights provides telemetry and performance monitoring for Copilot Studio agents, including activity, errors, and performance data across channels.
Question 5
A company has an Azure environment that supports multiple business units.
The company plans to implement an AI solution that will perform sentiment analysis on customer product reviews.
You need to evaluate the potential cost of the solution to support return on AI investment (ROAI) analysis.
What should you use?
A. Azure Reservations
B. Microsoft Fabric SKU Estimator
C. Anomaly Detection in Azure Cost Management
D. Azure pricing calculator
Show Answer
Correct Answer: D
Explanation: The Azure pricing calculator is used to estimate the cost of planned Azure deployments before implementation. It helps model the expected costs of AI services, compute, storage, and other resources, making it the appropriate tool for evaluating potential costs as part of return on AI investment (ROAI) analysis. The other options are for reserved capacity discounts, Microsoft Fabric capacity estimation, or monitoring existing Azure costs rather than forecasting new solution costs.
Question 5
A company has an AI agent that automates the review of customer feedback stored in a cloud database.
You plan to generate monthly reports from the agent's output to provide insights into customer sentiment and guide product development and marketing.
You need to ensure that the data ingested by the agent is clean and suitable for the intended use.
What should you do to prepare the data?
A. Identify and address missing or inconsistent data.
B. Sort the database by customer last name.
C. Ensure that the size of the database does not exceed 100 GB.
D. Verify data privacy and security compliance.
Show Answer
Correct Answer: A
Explanation: Identify and address missing or inconsistent data to improve data quality and ensure the agent can produce reliable sentiment insights. Sorting by last name or limiting database size does not clean the data; privacy and security compliance is important but is not the data-cleaning step asked for.
Question 6
A company has an Azure environment that supports multiple business units.
The company plans to implement an AI solution that will perform sentiment analysis on customer product reviews.
You need to evaluate the potential cost of the solution to support return on AI investment (ROAI) analysis.
What should you use?
A. Azure savings plans
B. Microsoft Fabric SKU Estimator
C. Cost Management + Billing
D. Azure Monitor
Show Answer
Correct Answer: C
Explanation: Cost Management + Billing is used to estimate, analyze, forecast, and allocate Azure costs across subscriptions, resource groups, and business units. It supports budgeting and cost analysis needed to evaluate the expected cost of an AI solution for return on AI investment. Azure Monitor is for monitoring, Azure savings plans are a pricing option rather than a cost analysis tool, and Microsoft Fabric SKU Estimator is specific to Fabric capacity sizing.
