Microsoft Microsoft Certifications PL-400 Questions & Answers

• Question 291:

  You fix a bug in the code of your application, which is currently on version 10.0.2.1.

  You need to publish an updated version of the solution.

  Which version identifier should you use?

  A. 10.0.3.1

  B. 10.0.2.2

  C. 10.1.0.2

  D. 11.0.0

  Correct Answer: B

  The version number are ....

  This is just a bug fix so we only update the revision number.

  Note: When we create patches in Dynamics 365, the system will automatically increment the build version (you can overwrite the chosen number when you create the patch). For example, if our solution starts at 1.0.0.0, we export it to

  become 1.0.0.1. We then create a patch, and the version of the patch is 1.0.1.1. If we export it now, it might become 1.0.1.2. In all cases, the build or version number has been incremented. Patches require the build or version number to

  increment, but not the major or minor version.

  Incorrect:

  Not C: This is not a minor update.

  Not D: This is not a major update.

• Question 292:

  A client uses a model-driven app that is deployed by using a managed solution in the production environment. The app contains only entities and UI components and has no custom code or extensions to the platform.

  The client needs an exact copy of the app with a different name in the production environment.

  You need to recreate this app in production without disrupting the end users.

  What should you do?

  A. Select the original model-driven app, select Edit, and then select Save As.

  B. Create a new model-driven app. Select the Use existing solution to create the App check box, and then select the solution that contains the original app.

  C. Select the managed solution and select Clone.

  D. Create a new model-driven app, manually add each component, and then recreate its original functions.

  E. Add the original app to a solution, export it as unmanaged, import it into a test environment and rename it, and then deploy it back into production.

  Correct Answer: B

  The option Use existing solution allow users to select a specific solution for this app. Users can create a whole new design from scratch by not checking check box of use existing solution.

• Question 293:

  You plan to create a canvas app to manage large sets of records. Users will filter and sort the data.

  You must implement delegation in the canvas app to mitigate potential performance issues.

  You need to recommend data sources for the app.

  Which two data sources should you recommend? Each correct answer presents a complete solution.

  NOTE: Each correct selection is worth one point.

  A. SQL Server

  B. Microsoft Dataverse

  C. Azure Data Factory

  D. Azure Table Storage

  Correct Answer: AB

  When you are creating reports from large data sources (perhaps millions of records), you want to minimize network traffic.

  Working with large data sets requires using data sources and formulas that can be delegated. It's the only way to keep your app performing well and ensure users can access all the information they need. Delegation is supported for certain

  tabular data sources only.

  These tabular data sources are the most popular, and they support delegation:

  Microsoft Dataverse

  SharePoint

  SQL Server

• Question 294:

  An organization has a Dynamics 365 Customer Engagement.

  You plan to use a JavaScript web resources file in the Accounts form. The file has a dependency on two image web resource files and on the custom field new_placeofbirth in the Account entity.

  You need to add the dependencies for the JavaScript file.

  Which three action should you perform? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. Open the web resource file, add the two image web resources to the dependency's lists, and then add the custom field new_placeofbirth to the dependency's list.

  B. From Settings, select Customizations and then select Customize the System.

  C. In the Account form, select Form Properties, select Non-Event Dependencies, and then add the custom field new_placeofbirth.

  D. Select Account, select Forms, and then select the Account form.

  E. From Web Resources, select the JavaScript file for the Account form and then select the JavaScript file.

  F. In the Account form, select Form Properties and add the primary JavaScript file and the other two images web resources in Form Libraries.

  Correct Answer: BCD

  Step 1 (B): From Settings, select Customizations and then select Customize the System.

  Step 2 (D): Select Account, select Forms, and then select the Account form.

  Step 3 (C): In the Account form, select Form Properties, select Non-Event Dependencies, and then add the custom field new_placeofbirth.

  In our Dynamics 365 forms, there are measures we can take to ensure fields that are being used by JavaScript are not removed from forms. To prevent this from happening, we can go to Form Properties and select the Non-Event Dependencies, and add the website field:

• Question 295:

  An organization uses Dynamics 365 Sales. You plan to add a custom button to the app ribbon.

  You need to ensure that the button displays only when conditions specified by business rules are met.

  Which two code segments can you use? Each correct answer presents a complete solution.

  NOTE: Each correct selection is worth one point.

  A. gridContext.refresh();

  B. formContext.ui.refreshRibbon(refreshAll);

  C. formContext.data.refresh(save).then(successCallback, errorCallback);

  D. formContext.ui.refreshRibbon();

  E. formContext.getControl(arg).refresh();

  Correct Answer: BD

  B: formContext.ui.refreshRibbon(refreshAll);

  Causes the ribbon to re-evaluate data that controls what is displayed in it.

  Indicates whether all the ribbon command bars on the current page are refreshed. If you specify false, only the page-level ribbon command bar is refreshed. If you do not specify this parameter, by default false is passed.

  Remarks: This function is typicaly used when a ribbon (RibbonDiffXml) depends on a value in the form. After your code changes a value that is used by a rule, use this method to force the ribbon to re-evaluate the data in the form so that the

  rule can be applied.

  D: If role is there - just refresh the ribbon to see the button if (isButtonEnabled) {

  formContext.ui.refreshRibbon();

  }

  },

• Question 298:

  You are deploying a Power Apps app that uses the custom connector for ServiceNow.

  The app loads very slowly for some users. You determine that all records from ServiceNow are being retrieved for every user.

  The app must load only incidents that are assigned to each user.

  You need to limit the number of records that the connector returns.

  What should you do?

  A. Apply a Lifecycle Services asset scope

  B. Apply a business process flow

  C. Apply the Azure APIM parameter

  D. Apply a connector policy template

  Correct Answer: D

  You can configure policy templates for custom connectors. Policies allow you to modify the behavior of a custom connector at runtime. You can use policies to perform data conversion, route requests, set parameter values, and more. You can configure policies directly in the custom connector API properties file before import, or you can do it from the maker portal in the custom connector designer by applying policy templates.

  Note: ServiceNow Action: GetRecords Summary: List Records Description: Gets records of a certain ServiceNow object type like 'Incidents' Syntax:ServiceNow.GetRecords (string tableType, [advanced][Optional]boolean sysparm_display_value, [advanced][Optional]boolean sysparm_exclude_reference_link, [advanced][Optional]string sysparm_query, [advanced][Optional]integer sysparm_limit, [advanced][Optional]integer sysparm_offset)

• Question 300:

  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 in the review screen.

  A university implements Dynamics 365 Sales. Several departments use opportunity records to bid for funding for projects within their own departments. You configure the system to ensure that each department can only work on their own

  records.

  Employees in multiple departments often need to work together on an opportunity. Employees report that they are not able to see opportunities from other departments.

  You need to ensure that employees from more than one department can work on the same opportunities when necessary.

  Solution: Use access team templates and give access to members in the two departments.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead use position hierarchy security and define the two departments as positions.
