• Question 282:

  A company is developing multiple plug-ins.

  One of the plug-ins keeps failing.

  You need to debug the plug-in.

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

  NOTE: Each correct selection is worth one point.

  A. Highlight the plug-in step and select Debug in the Plug-in Registration tool

  B. Copy the pdb file into the server/bin/assembly folder

  C. Select Start Profiling in the Plug-in Registration tool

  D. Attach the debugger to the w3wp.exe process

  E. Install the plug-in profiler

  Correct Answer: ACE

  Step 1: Install plug-in profiler

  Because the plug-in executes on a remote server, you cannot attach a debugger to the 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.

  Step 2: Start profiling

  In the Plug-in Registration tool, select the (Step) BasicPlugin.FollowupPlugin:

  Create of account step, and click Start Profiling. In the Profiler Settings dialog accept the default settings and click OK to close the dialog.

  Step 3: Debug your plug-in

• Question 283:

  A create a model-driven app. You run Solution checker. The tool displays the following error: Solution checker fails to export solutions with model-driven app components.

  You need to resolve the issue. What should you do?

  A. Manually export the solution before running Solution checker

  B. Assign the Environment Maker security role to the Power Apps Checker application user

  C. Assign the System Administrator security role to your user ID

  D. Disable the Power Apps Checker application user

  E. Assign the Environment Maker security role to your user ID

  Correct Answer: B

  To resolve this issue, grant the Environment Maker security role to the Power Apps Checker application user.

  Note: Solution checker fails to export solutions with model-driven app components If a solution contains a model-driven app, Solution Checker might fail to export the solution for analysis. This error is caused by role-based security for sharing

  of apps. If the Power Apps Checker application user does not have appropriate access to model-driven apps, any solutions containing them will fail to export with solution checker.

  An organization has an Azure SQL Database instance that must be synchronized daily with data from Dynamics 365 Sales. A large amount of data might need to be synchronized on some days.

  You need to reduce the time required to synchronize data.

  Solution:

  Enable change tracking for entities that will be synchronized.

  Use the Data Export Service to sync data between the database and Dynamics 365 Sales.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: A

  Large organizations that synchronize their data with external data sources can now enable entities for change tracking. You can export or retrieve a selected set of data, and then keep the external data warehouse in sync.

  The Data Export Service is an add-on service made available on Microsoft AppSource that adds the ability to replicate data from Common Data Service database to an Azure SQL Database store in a customer-owned Azure subscription.

  The Data Export Service intelligently synchronizes the entire data initially and thereafter synchronizes on a continuous basis as changes occur (delta changes) in the system.

  You can use the Data Export Service with model-driven apps in Dynamics 365, such as Dynamics 365 Sales and Dynamics 365 Customer Service.

• Question 285:

  A company uses the Data Export Service (DCS) to refresh their Azure SQL Data Warehouse instance. The data warehouse is used for historical trend analysis and forecasting.

  The refresh process from the Common Data Service (COS! environment lo the data warehouse has errors. Users report that data is missing.

  A CDS lest environment that contains DES is available to troubleshoot the import outside of the production environment. You create a new database for testing.

  You need to configure the lest environment to point to the new database.

  What should you create first lo access the database?

  A. A new secret In Azure Key Vault

  B. A new user in the SQL database

  C. A new export profile in CDS test

  D. A new application registration

  Correct Answer: A

  Because this service requires access to an external Microsoft Azure SQL Database from Dynamics 365 (online), a number of prerequisites must be satisfied before you can successfully access this service including:

  Global / Tenant Admin access, or an Azure Key Vault must be provisioned and the setup user must have permissions on Secrets.

• Question 289:

  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.

  Register a step at the endpoint which 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: B

  Need a plug-in or a custom workflow.

  Note: 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.

• Question 290:

  A company plans to create an order processing app. When orders are created, the app will perform complex business logic and integrate with several external systems.

  Orders that have a large number of line items may take up to six minutes to complete. Processing for each order must be completed in one operation to avoid leaving records in an incomplete state.

  You need to recommend a solution for the company.

  What should you recommend?

  A. an asynchronous workflow that uses a custom workflow activity

  B. a real-time workflow that uses a custom action

  C. a webhook that connects to an Azure Function

  D. an asynchronous plug-in

  Correct Answer: B

  Real-time Workflows roll back all changes if it fails. As the Workflow is going through the process itself, if it fails, it will roll back all of the prior steps taken.
