Question 1
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear on the review screen. An agent uses a flow that calls an external service which can occasionally fail or time out. When a failure occurs, the agent must meet the following requirements: Must not terminate silently. Must send a notification containing the error details. You need to configure the agent flow so that failures are handled in a controlled and predictable way. Solution: Retry the failing action without handling failure. Does the solution meet the goal?
Show answer and explanation
Correct answer: B. No
Retrying without handling failure does not meet the stated requirements. The solution must ensure the agent does not terminate silently and must send notifications with error details. Simply retrying the action without any error handling mechanism leaves both requirements unmet, as failures could still occur silently after exhausting retries.
Why the other options are wrong
- A. This solution fails because retrying without error handling does not send notifications or prevent silent termination.
Question 2
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear on the review screen. An agent uses a flow that calls an external service which can occasionally fail or time out. When a failure occurs, the agent must meet the following requirements: Must not terminate silently. Must send a notification containing the error details. You need to configure the agent flow so that failures are handled in a controlled and predictable way. Solution: Configure run after conditions for failure paths. Does the solution meet the goal?
Show answer and explanation
Correct answer: A. Yes
Configuring run after conditions for failure paths directly addresses both requirements. Run after conditions allow the flow to detect when the external service call fails and execute alternative actions, such as sending a notification with error details. This prevents silent termination and ensures controlled handling of failures through predictable error paths.
Why the other options are wrong
- B. This approach meets the requirements by enabling failure path configuration and error notification handling.
Question 3
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear on the review screen. An agent uses a flow that calls an external service which can occasionally fail or time out. When a failure occurs, the agent must meet the following requirements: Must not terminate silently. Must send a notification containing the error details. You need to configure the agent flow so that failures are handled in a controlled and predictable way. Solution: Send a notification with relevant error details. Does the solution meet the goal?
Show answer and explanation
Correct answer: A. Yes
Sending a notification with relevant error details directly satisfies one of the two key requirements: the agent must send a notification containing error details. This action ensures users are informed of failures and prevents silent termination. While it addresses one requirement, it is a necessary component of the complete solution.
Why the other options are wrong
- B. Sending an error notification is a requirement explicitly stated in the problem, making this solution correct.
Question 4
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear on the review screen. A company is configuring an agent in Copilot Studio that uses a generative answers node inside multiple topics. The company requires responses to meet the following requirements: Must use an executive summary format. Must apply only within a specific topic. Must continue using configured knowledge sources. Must comply with connector security controls. You need to configure a custom prompt to meet the formatting requirements. Solution: Remove the generative answers node and rely only on the custom prompt to produce formatted responses. Does the solution meet the goal?
Show answer and explanation
Correct answer: B. No
Removing the generative answers node would eliminate the ability to use configured knowledge sources, which is explicitly listed as a requirement that must continue. The solution requires customizing the prompt within the existing generative answers node to apply formatting requirements while preserving the use of knowledge sources, not replacing the node entirely.
Why the other options are wrong
- A. Removing the generative answers node breaks the requirement to continue using configured knowledge sources.
Question 5
An agent calls a flow. The agent requires structured output values to be returned. The agent receives unexpected or empty values. You need to configure the agent so that data is exchanged correctly between the agent and the flow. What should you do?
Show answer and explanation
Correct answer: A. Validate parameter definitions.
When an agent receives unexpected or empty values from a flow, the issue typically stems from parameter definition mismatches. Validating parameter definitions ensures the agent and flow have matching schemas, data types, and required fields, enabling correct data exchange. Parameter validation is the first diagnostic step and most direct solution for structured output issues between agent and flow components.
Why the other options are wrong
- B. Changing the trigger schema may not resolve the issue if the problem is in how parameters are defined or mapped between components.
- C. Reviewing run history provides diagnostics but does not configure the system to exchange data correctly.
- D. Adding Parse JSON is a flow-level operation that does not address parameter definition validation at the agent-flow interface.
- E. Republishing the agent without fixing parameter definitions will not resolve the underlying data exchange problem.
Question 6
A company is building an agent in Copilot Studio. The agent must meet the following requirements: Responses must be grounded in approved internal content. The agent must be able to retrieve information from configured data sources in a topic. You need to configure the agent so that topic responses are grounded from custom data sources. What should you configure?
Show answer and explanation
Correct answer: C. Configure knowledge sources in a generative answers node.
To configure topic responses grounded in custom data sources, configure knowledge sources in a generative answers node within topics. This enables the agent to retrieve information from configured data sources at the topic level, ensuring responses are grounded in approved internal content and meeting the requirement for responses to be sourced from custom data sources.
Why the other options are wrong
- A. Analytics review usage patterns but do not configure data source grounding.
- B. A custom prompt instructing the agent to use company data is weaker than actual knowledge source configuration and does not guarantee grounding.
- D. Configuring knowledge sources only at agent level does not allow topic-specific data source selection and retrieval.
- E. Increasing response length does not address knowledge source configuration or grounding requirements.
Question 7
A company is deploying an agent for employees. The company has the following requirements: Access must be restricted to the internal employees only. End-user authentication must be enforced. You need to configure the agent based on the company requirements. What should you do?
Show answer and explanation
Correct answer: A. Select Authenticate with Microsoft Entra ID for the agent.
To restrict access to internal employees only with enforced end-user authentication, select Authenticate with Microsoft Entra ID for the agent. This configuration requires employees to authenticate using organizational Microsoft Entra ID credentials, ensuring only authorized internal users can access the agent.
Why the other options are wrong
- B. Require Secure Access in Web channel security alone does not enforce end-user authentication or restrict to employees only.
- C. Publishing as a public website experience contradicts the requirement to restrict access to internal employees only.
- D. Personal account authentication does not restrict access to organizational employees and does not meet enterprise requirements.
Question 8
An agent in Copilot Studio already exists in a development environment. You need to prepare the agent so it can be moved to a production environment using the supported solution-based approach. You need to create an exportable package that contains the existing agent. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
Show answer and explanation
Correct answer: C, E. Export the unmanaged solution that contains the agent; Create a custom solution and add the existing agent to the solution.
To prepare an existing agent for production deployment using the solution-based approach: (C) Export the unmanaged solution that contains the agent creates the exportable package, and (E) Create a custom solution and add the existing agent to the solution establishes the proper solution structure before export. Unmanaged solutions in development allow modifications and can be exported to production environments where they can be converted to managed solutions if needed.
Why the other options are wrong
- A. Removing agent topics from the solution would corrupt the agent and prevent successful export.
- B. Converting to managed solution before export prevents further modifications; solutions are converted to managed in the target environment after export.
- D. Publishing to a channel and exporting channel configuration is not the supported solution-based approach for moving agents between environments.
