You need to identify the Azure service to use for the Planning Hub application. Which service should you use?

A. Logic App
B. Service Bus
C. Key Vault
D. Function
Show Answer
Correct Answer: A
Explanation:
The Planning Hub application requires an out-of-the-box service to orchestrate a multi-step business process after submission: retrieving customer and improvement details, requesting approval in Microsoft Teams, calling a REST API, implementing retry logic with delays, sending failure notifications, and updating status. Azure Logic Apps is designed specifically for workflow orchestration and integration, provides native connectors for Teams, Outlook, Dataverse, and HTTP APIs, supports built-in retry policies and error handling, and requires minimal code. Service Bus is for messaging, Key Vault is for secret storage, and Azure Functions focuses on custom code rather than end-to-end workflow orchestration.

Question 35

DRAG DROP - You plan to integrate Microsoft Dataverse data to a system using a Microsoft Azure function. You configure the message containing the data to be sent asynchronously. You need to plan for the following errors: • The failure of business logic that uses a synchronous plug-in. • The Azure function is unreachable. You need to determine the behavior when an error occurs. Which retry behavior will be used? To answer, move the appropriate retry behaviors to the correct error scenarios. You may use each retry behavior once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.

Illustration for PL-400 question 35
Show Answer
Correct Answer: Plug-in failure: Message is not sent and will not retry. Azure Function unreachable: Message is not sent and will retry continually.
Explanation:
A synchronous plug-in failure causes the Dataverse operation to fail, so the asynchronous message is never sent and no retry occurs. If the Azure Function endpoint is unreachable, the message cannot be delivered, so Dataverse keeps retrying delivery until the endpoint becomes available.

Question 36

A company requires a plug-in that makes multiple requests to an external web service. The plug-in must not time out when the web service has issues or is slow to respond. You need to create the plug-in. What should you do?

A. Send requests to use multiple threads.
B. Register the plug-in to run synchronously.
C. Register the plug-in step once for each web service request.
D. Set the HTTP connection timeout value explicitly to limit how long each connection can remain open.
Show Answer
Correct Answer: D
Explanation:
The plug-in must avoid exceeding the platform execution time when calling a slow or unresponsive external service. Explicitly setting the HTTP connection timeout ensures each request waits only a controlled amount of time instead of hanging indefinitely, allowing the plug-in to handle failures gracefully and preventing overall plug-in timeouts. The other options do not address external call latency or can worsen timeout behavior.

NOTE: Each correct selection is worth one point.

A. pac solution version
B. pac solution import
C. pac pcf push
D. pac pcf version --strategy manifest
Show Answer
Correct Answer: B, C
Explanation:
The issue states that changes to the eligibility assessment tool do not appear in the development environment after deployment. This commonly occurs when solution changes or PCF components are not properly deployed. Running **pac solution import** ensures that the latest version of the solution containing the Suitability Assessment Tool is imported into the development environment. Running **pac pcf push** is required when the application uses Power Apps Component Framework (PCF) components, as it deploys the updated component directly to the environment. Without this step, PCF changes will not be visible.

A. Power App Component Framework (PCF) control
B. view
C. component library
D. form
Show Answer
Correct Answer: C
Explanation:
The Suitability Assessment Tool must be built using modular, reusable components that integrate natively with Power Platform, are optimized for tablet use, and can be reused by other applications. A Power Apps component library is designed specifically for this purpose, enabling low-code, reusable components across canvas apps within solutions. This aligns with the requirement for out-of-the-box solutions and rapid development, whereas PCF controls are pro-code and only necessary for highly customized UI or behavior not achievable with standard components.

If an error occurs after three times, the application should send an email notification to the application support team. o Must record the status on the funding application. Suitability Assessment Tool - The company plans to implement a new application named the Suitability Assessment Tool for the assessors. The new application has the following requirements: • Must integrate with Microsoft Power Platform. • Assessors must be able to complete the eligibility assessment by using the Suitability Assessment Tool. The assessors must be able to upload photographs to the on-premises file share. • Must be developed by using modular components that can be used by other applications. • Must be optimized for use on tablet devices. • All changes to the application must be completed in the Suitability Assessment Tool solution. Reporting - The company has the following requirements for a reporting solution: • The data source for the reporting solution must support incremental refreshes. • The solution must report accurate data if an error occurs. Issues - • A recent audit identified that all users can access the PII in the Planning Hub spreadsheet. • After a developer deploys a change to the production environment, a user reports information is loaded incorrectly to the test system when processing a funding application. • After deploying a change to the new eligibility assessment tool in the development environment, you observe that the changes do not appear in the development environment. • After removing a column from the Planning Hub application and deploying the changes to the production environment, you observe that the column is still present. • You deploy the customizations for the data model. Users report that the email address of the user who created the appointment is missing and that searches on the description information do not return any results. You need to design the Planning Hub data model. Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Show Answer
Correct Answer: Select the Contact table. Modify a column. Enable column security. Create column security profile.
Explanation:
The Planning Hub must store customer PII, so the existing Contact table is used as the base. Required fields such as creator email and searchable description are added or adjusted by modifying columns. Column-level security is then enabled on sensitive PII fields, and a column security profile is created to restrict access to team leaders and senior managers only.

Question 41

You are creating a FetchXML query. The query must return data from a table and return filtered data from a related table. You need to configure the FetchXML query. Which two elements should you use? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

A. attribute
B. link-entity
C. alias
D. condition
Show Answer
Correct Answer: B, D
Explanation:
To return data from a primary table and apply filters based on a related table in FetchXML, you must use a link-entity element to join the related table, and a condition element within a filter to apply the required filtering criteria on that related table. Attributes select columns, and alias is optional for naming, but they do not handle relationships or filtering logic.

Question 42

A company deploys managed customizations by using two solutions, SolutionA and SolutionB. The solutions share components with one another. A developer for SolutionA requires a new development environment. Customizations made in SolutionA must not interfere with customizations made in SolutionB. You need to import solutions to prepare the environment. What should you do?

A. Import SolutionA as managed and SolutionB as unmanaged.
B. Import SolutionA and SolutionB as unmanaged.
C. Import SolutionA as unmanaged and SolutionB as managed.
D. Import SolutionA and SolutionB as managed.
Show Answer
Correct Answer: C
Explanation:
In a development environment, the solution being actively worked on should be imported as unmanaged so the developer can modify and publish changes. To ensure that customizations in SolutionA do not interfere with SolutionB—especially since they share components—SolutionB should be imported as managed, which seals its components and prevents accidental edits or overwrites. This aligns with recommended ALM practices in Power Platform.

Question 43

DRAG DROP - You are testing the deployment of a model-driven app. Microsoft Entra ID groups are used exclusively to manage environment- and team-level permissions. Users encounter several access-related issues that prevent them from testing the app. You need to select the component to use to resolve each issue by using the principle of least privilege. What should you assign to resolve each issue? To answer, move the appropriate resolutions to the correct issues. You may use each resolution once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.

Correct Answer: Unable to access a single environment: Microsoft Entra ID group Unable to update Account rows: Security role Unable to access rows owned by the human resources team: Team Unable to create a sandbox environment: Microsoft Power Platform
Explanation:
Environment access is controlled via Entra ID group membership. Row-level create/update permissions come from Dataverse security roles. Access to records owned by another group is granted through team membership. Environment creation rights are governed at the tenant level in the Power Platform admin settings.
