• Question 31:

  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.

  You must create a new attribute class in which to mark other classes in the ISV solution and their respective methods with the error levels Warning and Error. You have the following class: (Line numbers are included for reference only.)

  

  You need to ensure that the compiler will report an error if code calls the bike method.

  Solution:

  Create the following attribute class:

  

  Insert the following code at line 04:

  [SysObsoleteAttribute("Deprecated. Please use the bicycle class instead.", false)]

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  The second parameter of SysObsoleteAttribute should be true to produce a compiler error message. If it set to false it produces a compiler warning message.

  SysObsoleteAttribute The system provides several attributes, including the SysObsoleteAttribute class. One use of the SysObsoleteAttribute class is to tell the X++ compiler that it should fail if a particular method is called in the source code. The X++ compiler rejects the compile, and it displays the specific message that is stored in this use of the attribute. The SysObsoleteAttribute class can also be used to tell the compiler to issue warning messages instead of errors.

  // X++

  [SysObsoleteAttribute("The Automobile class might be a better choice for faster performance.", false)]

  class Bicycle

  {

  // Members of the Bicycle class go here.

  }

  Note: Each object (Form, class, report, method) in AX has any parent class. That parent class can be an x++ class or a kernel class. Super() means calling a method with the same name in parent class.

  Writing code before super() means, doing something before "execution"

  Writing code after super() means doing something after "execution"

• Question 32:

  Users report that a company's Dynamics 365 Finance website is slow.

  You suspect that a SQL query attached to the task GetFormInteractionTask is the cause.

  You need to determine how long it takes for the query to run and return results.

  What should you use?

  A. Performance timer

  B. Performance monitor

  C. Microsoft Edge debugging tools

  D. Fiddler

  Correct Answer: A

  Performance timer is a tool that helps you to determine why your system's performance might be slow.

  To open the Performance timer, open your webpage with the added parameter debug=develop: https://yoursite.cloud.test.dynamics.com/en/?cmp=USMFanddebug=develop Note: When you run in debug mode you will notice slower

  performance. You can quickly get an overview of most performance issues by pressing F12 and working with the debugging tools that are available in your browser. The timer will show up here.

  To open a list page, for example, such as the purchase order list page, click the Performance timer. The following screenshot shows the separation between client time and server time, and the total time.

  You need to set up the form for the menu.

  What should you add to the menu?

  A. display menu item

  B. menu reference

  C. output menu item

  D. action menu item

  Correct Answer: A

• Question 34:

  A company requires a Power Apps app that will enable users to view and create new leads in Dynamics 365 from the app.

  The data is in a custom entity named LeadsTable, which is not accessible outside Dynamics 365.

  You need to make the data available outside Dynamics 365.

  What should you do?

  A. Enable IsPublic for the data entity linked to the LeadsTable.

  B. Assign the create, read, update, and delete operations for the LeadsTable to the sales associate role.

  C. Enable all create, read, update, and delete operations on the LeadsTable table.

  D. Create an aggregate data entity for the LeadsTable.

  E. Enable data management capabilities on the data entity.

  Correct Answer: A

  The data entities in Dynamics 365 for Finance and Operations has 'IsPublic' property which when enabled, makes the data entity available to be consumed via OData. List of data entities exposed to Odata can be viewed using the URL [baseURL]/data, where baseURL is the URL to access Dynamics 365 Finance and Operations.

  Some of the data entities do not have this 'IsPublic' property enabled out-of-the-box and therefore not exposed for OData.

• Question 36:

  You need to prepare to deploy a software deployable package to a test environment. What should you do to prepare?

  A. In Visual Studio, create a Dynamics 365 deployment package and upload the package to the asset library.

  B. In Azure DevOps, queue a build from the corresponding branch and upload the model to the asset library.

  C. In Azure DevOps, queue a build from the corresponding branch and upload the package to the asset library.

  Correct Answer: A

  Create deployable packages of models

  An AOT package is a deployment and compilation unit of one or more models that can be applied to an environment. It includes model metadata, binaries, reports and other associated resources. One or more AOT packages can be

  packaged into a deployable package, which is the vehicle used for deployment of code (and customizations) on demo, sandbox, and production environments.

  Create a deployable package

  We recommend using a build environment to create deployable packages. You can also create a deployable package on a development environment.

  On a development environment, after you have completed development and testing, follow these steps to create a deployable package in Visual Studio.

  1.

  In Microsoft Visual Studio, select Dynamics 365 > Deploy > Create Deployment Package.

  2.

  Select the packages that contain your models, and then select a location in which to create the deployable package.

  3.

  After a deployable package is created, sign in to Lifecycle Services, and then, in your LCS project, click the Asset Library tile.

  4.

  Upload the deployable package that you created earlier.

• Question 37:

  A company uses Dynamics 365 Finance.

  You must add fields to a standard table in Visual Studio.

  You need to create an extension of the table.

  What should you do?

  A. Create an extension class for the base table.

  B. Drag the table from the AOT to the project.

  C. Create a new table object in the pitied.

  D. Create a table extension from the base table.

  Correct Answer: D

  To add a new field to an existing table, you must first create a table extension. For example, to add a field that holds the radius of the released product, you must create an extension for the InventTable table in your model

  Reference: https://docs.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/extensibility/add-field-extension

• Question 38:

  A company plans to integrate Dynamics 365 finance and operations apps with an external application.

  The apps must send each vendor's name and address in a single field to the external application.

  You need to add a computed field to meet the requirement.

  What should you do?

  A. Create an extension for VendTable and then add the new display method.

  B. Create an extension of VendVendorV2Entity, select New, and then select Siting Unmapped Field.

  C. Create an extension for VendVendorV2Entity, select the Fields node, select New, and then select Mapped Field.

  Correct Answer: B

  How to extend a data entity to add a custom virtual field in Dynamics 365 Finance and Operations Unmapped fields include 2 types: Computed fields are generated by SQL Virtual fields are generated by custom X++ code

  How to Add a Custom Virtual Field

  1.

  In Visual Studio, open your project under your own custom model. Then in AOT window, find the standard data entity that you want to extend so as to create extension of it. Open the extended data entity to add a new unmapped field

  2.

  Etc.

  Incorrect:

  Not C: Mapped fields are mapped directly to fields of a data source.
