  Requirements. Historical Information Tracking

  You must create a process to identify individuals as a person of interest that the company should consider hiring. You must assign each individual a score based on their past interactions.

  *

  Whether the individual has any of the 12 designations or certifications that the company considers significant

  *

  Etc.

  Each contact can have 0, 1, or many designations or certifications.

  Incorrect:

  *

  A Lookup column cannot store information on 12 designations or certifications

  The LookUp function finds the first record in a table that satisfies a formula. Use LookUp to find a single record that matches one or more criteria.

  *

  A Choices column cannot store information on 12 designations or certifications

  The Choices function returns a table of the possible values for a lookup column.

  Use the Choices function to provide a list of choices for your user to select from. This function is commonly used with the Combo box control in edit forms.

• Question 194:

  You are designing a one-way integration from the Common Data Service to another system.

  You must use an Azure Function to update the other system. The integration must send only newly created records to the other system. The solution must support scenarios where a component of the integration is unavailable for more than a

  few seconds to avoid data loss.

  You need to design the integration solution.

  Solution: Register a service endpoint in the Common Data Service that connects to an Azure Service Bus queue.

  Register a step at the endpoint which runs asynchronously on the record's Create message and in the portoperation stage.

  Configure the Azure Function to process records as they are added to the queue.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: A

• Question 195:

  You are developing a Power Platform solution. The solution connects to a third-party accounting system by using a Web API through a Power Apps app that automatically exchanges contacts with the sales data. You have the following code: (Line numbers are included for reference only.)

  

  You need to ensure that the code only synchronizes data that was not previously synchronized.

  Which code segment should you insert at line 02?

  A. Prefer: odata.track-changes

  B. Prefer: odata.allow-entityreferences

  C. Prefer: odata.include-annotations

  Correct Answer: A

  Use change tracking to synchronize data with external systems

  The change tracking feature in Microsoft Dataverse provides a way to keep the data synchronized in an efficient manner by detecting what data has changed since the data was initially extracted or last synchronized. This article discusses

  how to enable and retrieve changes for a table.

  Retrieve changes for a table using the Web API

  Changes made in tables can be tracked using Web API requests by adding the Prefer: odata.track-changes header. This header requests that a delta link be returned which can subsequently be used to retrieve table changes.

  Delta links are opaque, service-generated links that the client uses to retrieve subsequent changes to a result. They are based on a defining query that describes the set of results for which changes are being tracked. For example, the

  request that generated the results containing the delta link. The delta link encodes the collection of tables for which changes are being tracked, along with a starting point from which to track changes.

• Question 196:

  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 are designing a one-way integration from the Microsoft Dataverse to another system.

  You must use an Azure Function to update the other system. The integration must send only newly created records to the other system. The solution must support scenarios where a component of the integration is unavailable for more than a

  few seconds to avoid data loss.

  You need to design the integration solution.

  Solution: Register a service endpoint in the Dataverse instance that connects to an Azure Service Bus queue.

  Create and register an Azure-aware plug-in that uses the service endpoint.

  Register a step on the plug-in that runs asynchronously on the record's Create message and in the post-operation stage.

  Configure the Azure Function to process records as they are added to the queue.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: A

  Plug-ins are one of two methods used to initiate posting the message containing the data context to the Azure Service Bus, the other method being a custom workflow activity.

  Note: Microsoft Dataverse supports integration with Azure.

  For the Dataverse and Azure connection to work, there must be at least one solution in an Azure Service Bus solution account, where the solution contains one or more service endpoints.

  For a queue endpoint contract, a listener doesn't have to be actively listening.

• Question 197:

  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 are designing a one-way integration from the Microsoft Dataverse to another system.

  You must use an Azure Function to update the other system. The integration must send only newly created records to the other system. The solution must support scenarios where a component of the integration is unavailable for more than a

  few seconds to avoid data loss.

  You need to design the integration solution.

  Solution: Register a webhook in the Dataverse instance that connects to the Azure Function. Register a step on the webhook which runs synchronously on the record's Create message and in the post-operation stage.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead use asynchronous communication.

• Question 198:

  You are creating an integration between Microsoft Dataverse and an external system.

  Messages from Dataverse must be sent to Microsoft Azure Service Bus. An Azure Function will process the messages. Events must be published directly to the ServiceEndpoint for Azure Service Bus.

  You need to create code for the messages.

  Which class should you use?

  A. RemoteExecutionContext

  B. IWorkflowContext

  C. IPluginExecutionContext

  D. IExecutionContext

  Correct Answer: A

  Microsoft Azure solution For the Dataverse and Azure connection to work, there must be at least one solution in an Azure Service Bus solution account, where the solution contains one or more service endpoints. For a relay endpoint contract, a listener application that is “Dataverse-aware” must be actively listening on the endpoint for the Dataverse request on the Service Bus. For a queue endpoint contract, a listener doesn't have to be actively listening. A listener is made Dataverse-aware by linking it to the Microsoft.Xrm.Sdk assembly so that type RemoteExecutionContext is defined

  Note Data Context The data context contains the business data that is being processed as part of the current Dataverse operation. This processing was initiated when a request to perform a certain operation was made by a user, workflow, or application, to the Dynamics 365 platform. The data context is passed to any plug-ins or custom workflow activities that are registered with the event pipeline to execute on the specific request and table combination that is currently being processed. The data context is of type IPluginExecutionContext when it is being passed along the event execution pipeline and RemoteExecutionContext when it is posted to the Service Bus.

• Question 199:

  You create a plug-in to validate data.

  Users report that validation is not working as expected.

  You need to debug the plug-in.

  Which tool should you use?

  A. Plug-in profiler

  B. Power Platform Tools for Visual Studio

  C. Plug-in dashboard

  D. Plug-in Registration Tool

  Correct Answer: A

  Because the plug-in executes on a remote server, you cannot attach a debugger to the plug-in process. The plug-in profiler captures a profile of an executing plug-in and allows you to re-play the execution of the plug-in using Visual Studio on

  your local computer.

  Install plug-in profiler

  There are two tools available from which to run the Plug-in Profiler: the Plug-in Registration Tool and Power Platform Tools for Visual Studio.

  Start profiling

  Follow these steps to begin profiling a plug-in's execution.

  1.

  In the Plug-in Registration tool, select the (Step) BasicPlugin.FollowupPlugin: Create of account step you registered earlier, and click Start Profiling.

  2.

  When presented with the Profiler Settings dialog, accept the default settings and click OK to close the dialog. Reference: https://docs.microsoft.com/en-us/power-apps/developer/data-platform/tutorial-debug-plug-in

• Question 200:

  You are creating an integration that uses an Azure function to create records in the Microsoft Dataverse when leads are submitted from your company website.

  You create a user and grant the user the Basic User security role.

  You do not have administrator access to the environment you are using or access to Azure Active Directory. Company policy dictates that service accounts must be used for integrations, and integrations must not be granted privileges beyond

  what is needed.

  You need to recommend actions that an administrator should perform to configure access for the Azure Function. Which three actions should you perform? Each correct selection presents part of the solution. NOTE: Each correct selection is worth one point.

  A. Create an application registration in Azure Active Directory.

  B. Assign the system administrator security role to the application user.

  C. Assign the Power Platform administrator role to the application user in Azure Active Directory.

  D. Create a new security role with the minimum required permissions and assign to the application user.

  E. Grant the application delegated permissions to the Dynamics CRM API in Azure Active Directory.

  F. Deploy Azure B2B guest permissions to the application user.

  Correct Answer: ADE

  A: Registering an application with Azure Active Directory, enables a user with Power Apps user account to connect to their Microsoft Dataverse environment from external client applications using OAuth authentication.

  D: Use minimum permissions.

  E: In the application registration process you delegate permissions to the Dynamics CRM API in Azure Active Directory.

  Incorrect:

  Not B: The system administrator security role would give the user too much privileges.

  Not C: The Power Platform administrator role would give the user too much privileges.
