You are creating a .NET application to load a large volume of data into a Dataverse table with one default column value. A synchronous plug-in already sets the same default column value for new rows in the table.

To speed up the process, you must disable the plug-in during the data load. The data load must run during business hours. The load must not affect rows users may be creating.

You need to perform the operations.

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

NOTE: Each correct selection is worth one point.

  1. Send the BypassCustomPluginExecution as an optional parameter with the create request.
  2. Send the SuppressCallbackRegistrationExpanderJob as an optional parameter with the request.
  3. Disable the plug-in step prior to starting the data load.
  4. Set the BypassPluginExecution property on the CrmServiceClient.

Answer(s): A,C

Explanation:

Send the BypassCustomPluginExecution as an optional parameter with the create request:
This parameter is specifically designed to bypass plug-ins during a data load, ensuring better performance while not impacting other rows created by users. This approach is granular and only affects the specific operation being executed.

Disable the plug-in step prior to starting the data load:
Temporarily disabling the plug-in step ensures that the plug-in does not execute during the bulk data operation. After the data load is complete, the plug-in can be re-enabled. This approach impacts all operations on the table while the plug-in is disabled, so it must be carefully coordinated.



A company creates a custom connector for its cloud-based ERP system.

The company requires an authentication method that can be consumed by the custom connector.

You need to configure the authentication method.

Which authentication method should you use?

  1. basic authentication
  2. Windows Active Directory authentication
  3. certificate-based authentication
  4. password less authentication

Answer(s): A

Explanation:

Basic authentication is widely supported by custom connectors in Power Platform. It requires a username and password to authenticate and is straightforward to configure for cloud-based ERP systems. It is commonly used when connecting to external systems that do not natively support advanced authentication methods like OAuth.

Background:

Current environment
Adventure Works Cycles wants to replace their paper-based bicycle manufacturing business with an efficient paperless solution. The company has one manufacturing plant in Seattle that produces bicycle parts, assembles bicycles, and distributes finished bicycles to the Pacific Northwest.

Adventure Works Cycles has a retail location that performs bicycle repair and warranty repair work. The company has six maintenance vans that repair bicycles at various events and residences.

Adventure Works Cycles recently deployed Dynamics 365 Finance and Dynamics 365 Manufacturing in a Microsoft-hosted environment for financials and manufacturing. The company plans to leverage the Microsoft Power Platform to migrate all of their distribution and retail workloads to Dynamics 365 Unified Operations.

The customer uses Dynamics 365 Sales. Dynamics 365 Customer Service and Dynamics 365 Field Service.

Retail store information
Adventure Works Cycle has one legal entity, four warehouses, and six field service technicians.
Warehouse counting is performed manually by using a counting journal. All warehouse boxes and items are barcoded.

-Warehouse counting is performed manually by using a counting journal. All warehouse boxes and items are barcoded.
-The Adventure Works Cycles retail location performs bicycle inspections and performance tune-ups.
-Technicians use paper forms to document the bicycle inspection performed before a tune-up and any additional work performed on the bicycle.
-Adventure Works Cycles uses a Power Apps app for local bike fairs to attract new customers.
-A canvas app is being developed to capture customer information when customers check in at the retail location. The app has the following features:
-Customer selects yes or no if they are on the mailing list.
-Customer selects the amount of times they have visited the store.
-Customer selects the type of service needed.
-The search result returns all last name records that match the search term.

-Nine customers arrive in the repair area of the retail store, but no texts were sent to scheduled employees.
-Customers report that the response time from the information email listed on the Adventure Works Cycles website is greater than five days.
-CustomerC requested additional information from the parts department through the customer survey and has not received a response one week later.
-

You need to identify the execution mode that is being used for the ISV solution reported by User5. Which type of execution mode is in use?

  1. asynchronous
  2. atomicity
  3. transfer
  4. synchronous

Answer(s): D

Explanation:

User5 receives the error message: ‘Endpoint unavailable’ during a test of the technician dispatch ISV solution.

When you choose to use a synchronous execution mode any failure will be reported back to the user of the application with an Endpoint unavailable error dialog informing the user that the webhook service endpoint may be configured incorrectly or is not available.

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

You create and configure a Common Data Service application user.

You do not have administrator access to the Common Data Service environment you are using for 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.

  1. Create an application registration in Azure Active Directory.
  2. Assign the system administrator security role to the application user.
  3. Assign the Power Platform administrator role to the application user in Azure Active Directory.
  4. Create a new security role with the minimum required permissions and assign to the application user.
  5. Grant the application delegated permissions to the Dynamics CRM API in Azure Active Directory.
  6. Deploy Azure B2B guest permissions to the application user.

Answer(s): A,D,E

Explanation:

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.
