PL-400 Free Practice Questions

Question 1

You create a custom API as part of a solution that will be made available on Microsoft AppSource. You need to prevent others from using Dataverse code generation tools that create classes and use the messages for your custom API. What should you do?

Question 2

A company is testing a solution that you built by using access team templates. Users report that they are unable to access rows. You need to ensure that the solution works as expected. What should you do?

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. You have two tables, account and contact, with a parent-child relationship. Records in the account table can be created in the UI or from an external system integrated with Dataverse by using an Azure Function. When a user creates a record in the account table, a default record in the contact table must be created automatically. You need to implement a process to create the contact records. Solution: Create a JavaScript function that runs when the account record form is saved. Use the Web API in the JavaScript function to create the contact record. Does the solution meet the goal?

Question 4

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. You have two tables, account and contact, with a parent-child relationship. Records in the account table can be created in the UI or from an external system integrated with Dataverse by using an Azure Function. When a user creates a record in the account table, a default record in the contact table must be created automatically. You need to implement a process to create the contact records. Solution: Create a custom API bound to the account table that uses a plug-in. Use the Organization service to create the contact record. Does the solution meet the goal?

Question 5

DRAG DROP - You are writing code to integrate a system with Dataverse by using the Web API. The code must perform the following operations: • Upsert to create and update records • Upsert only to create new records You need to complete the requests to perform the operations. Which headers should you use? To answer, move the appropriate headers to the correct operations. You may use each header once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content.

Solution: Create a plug-in that runs when the account record is created. Use the Organization service to create the contact record. Does the solution meet the goal?

Question 7

A model-driven app form has JavaScript that runs during the OnLoad event. The event retrieves an account record and changes visibility to a form column based on one of the record columns. The following portion of code retrieves the account record: Xrm.WebApi.retrieveRecord('account', accountId)_ Users report that the form loads slowly. You need to improve the performance of the code that retrieves the account and changes visibility. What should you do?

Question 8

HOTSPOT - Users are directed to a form in a model-driven app through a special URL that passes values for three lookup columns. The form consists of three tabs: A, which is the default tab, B, and C. The form has JavaScript code registered on the OnLoad and OnSave events as follows: • OnLoad: A lookup column on each tab is used to retrieve data. The data is used to populate columns on that same tab. • OnSave: Data validation involves calculations of columns on the form. If a value is outside the acceptable range, the record must not be saved. Users report that loading and saving the form takes too long when they create a new record. You need to shorten the time it takes to load and save the form without losing functionality. Which new event registrations should you create? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Question 9

HOTSPOT - You are implementing a Power Automate flow in a model-driven app. The flow will facilitate an approval process to increase customer credit limits. A user must be able to initiate the process from a customer record. The user must be prompted for the amount of the increase. Once the increase is approved, the customer record must update to reflect the new amount. You need to add a trigger to the flow and locate the ID of the record to update. The flow should be written to use the least number of steps. How should you create the flow? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Question 10

HOTSPOT - You are extending a model-driven app by using modern commanding in Power Fx. When a user selects a button on the Opportunity form, the button must trigger an automation to generate a document by updating a single column in Dataverse. Users must affirm the action before it takes place and receive a message after it completes successfully. You need to write the formula. How should you complete the code segment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
