Microsoft Microsoft Certifications PL-400 Questions & Answers

• Question 201:

  You are creating a plug-in for an app that helps government employees get a proof of vaccination card. You must add the following information to a vaccination record before a proof of vaccination card is created:

  1.

  Vaccination type

  2.

  Date of vaccination

  3.

  Name of person administering the vaccine

  You need to register the plug-in.

  In which stage should you register the plug-in?

  A. PreValidation

  B. PostOperation

  C. MainOperation

  D. PreOperation

  Correct Answer: D

  1.

  Pre-Validation: is before the record even reaching the stage of pre-operation, so means not yet saved, it is the first layer, usually used for validation, but not many people use this, usually will just use pre-operation.

  2.

  Pre-Operation: is also before the record created, not yet database transaction committed.

  This is usually used to modify attribute value by system (logic code), validation as well.

  Any changes of attribute in the pre-validation would be dismissed if you modify the attribute from this stage.

  Since mentioned before, this is not yet created, so, there is no ID created at this point.

  3.

  Post-Operation: is after the record created, database transaction committed, and you would get the GUID.

• Question 203:

  You are implementing business logic for a model-driven app form by using multiple JavaScript web resources.

  The business logic, number of JavaScript files, and the columns that the business logic requires are expected to change frequently. Some form fields will not be visible. Occasionally, non-developers will also make changes to the form.

  You need to prevent columns referenced by the JavaScript from accidentally being removed from the form based.

  What should you do?

  A. Hide columns that should not be displayed.

  B. Set all columns as business required.

  C. Add all columns as non-event dependencies to the form.

  D. Add columns in each JavaScript file as a dependency.

  Correct Answer: D

  Column dependencies

  Starting with model-driven apps, if your JavaScript web resource depends on a table column value that you don't want to display in the form, you can set the column as a dependency for the JavaScript web resource. This means that the

  column will be available within the client API columns collection so you can get or set the value in your code. When you add a dependency this way, the controls collection of the column will be empty because there will be no control on the

  form.

  Before this feature you would need to manually add the column to the form and then configure the control to be hidden. Now you can establish this dependency more directly and eliminate the possibility that someone will remove the hidden

  column from the form.

  Incorrect:

  Not A: Hiding form elements is not a recommended way to enforce security. There are several ways people can view all the elements and data in the form when elements are hidden.

  You need to complete the component manifest.

  Which XML markup segment should you insert at line 03?

  A.

  B.

  C.

  D.

  E.

  Correct Answer: B

• Question 205:

  You are developing a Power Apps app to manage records in the Account table in Microsoft Dataverse.

  You must configure a Web API request to retrieve changes from the table.

  You need to configure the preference header for the API request.

  What should you include in the request header?

  A. odata.context

  B. odata.deltaLink

  C. odata.track-changes

  D. odata.nextLink

  Correct Answer: B

  The @odata.deltaLink Uri returned from the below example can be used to fetch changes in tables. In this example a new account was created and an existing account deleted. The delta link returned from the previous request fetches these changes, as shown in the example below.

  {

  "@odata.context":"[Organization URI]/api/data/v9.0/$metadata#accounts(name,accountnumber,telephone1,fax)", "@odata.deltaLink": "[Organization URI]/api/data/v9.0/accounts?$select=name,accountnumber,telephone1,faxand$deltatoken=919042%2108%2f22%2f2017%2008%3a10%3a44", "value":[

  {

  "@odata.etag":"W/\"915244\"",

  "name":"Monte Orton",

  "accountnumber":null,

  "telephone1":"555000",

  "fax":"10101",

  "accountid":"60c4e274-0d87-e711-80e5-00155db19e6d"

  } ] }

• Question 207:

  You develop a model-driven app to manage customer information. You have the system administrator security role on all environments.

  You create a business process flow that is associated with the Contact table. You grant users Create, Read, and Write permissions on the business process flow.

  Users report that the new business process flow does not appear when the users create new contact records. You verify that you can view the business process flow when you sign into the app and create a new contact record.

  You need to resolve the issue.

  What should you do?

  A. Grant users the Run Flows privilege.

  B. In the app designer, ensure that the business process flow is added to the app.

  C. Grant users the Organization Read permission on the Process table.

  D. Open the business process flow and associate the flow with the user security roles by using the Edit security button on the command bar.

  Correct Answer: D

  Configure Security Role In Dynamics 365 Business Process Flow

  Here are the steps to configuring security roles for a business process flow in Dynamics 365:

  Go to Setting > Security > Security Roles

  Choose the security role you want to add to the business process flow of your choice;

  Go to the Business Process Flows tab;

  You can view the existing security roles, if any, and their associated data privileges like create, read, delete and more. From this information, you can get to know which business process flows can be used for the particular security role you

  have chosen;

  You can add the security privileges to the selected security role by checking on the corresponding privileges;

  Then click on save and close.

• Question 208:

  You create a form in a model-driven app that uses data from the Lead table in a Microsoft Dataverse instance. You add a business rule to the Lead table. The business rule displays an error if the email address is null. You set the scope for

  the business rule to All Forms.

  You configure a Power Apps portal by using the same Microsoft Dataverse instance. You create a web page by using the Lead form.

  You need to ensure the same logic is applied on the Power Apps portal page.

  What are two possible ways to achieve the goal? Each correct answer presents a complete solution.

  NOTE: Each correct selection is worth one point.

  A. Deactivate the business rule. Change the scope for the rule to Table and then reactivate the rule.

  B. Replace the business rule logic with a Microsoft Power Automate cloud flow by using the Dataverse When a row is added, modified or deleted trigger.

  C. Extend the webFormClientValidate JavaScript function to replace the business rule logic. Edit the code in Power Apps Studio. Add the function in a
