  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: Configure the Azure Function with a timer trigger that runs every five minutes. The function will query the Dataverse instance and process records created in the last five minutes.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead use Azure Service Bus queue solution with asynchronous communication.

• Question 262:

  A company needs to illustrate the relationships of the entities in Dynamics 365 Sales.

  You need to select the appropriate tool to show this graphic.

  Which tool should you select?

  A. Metadata diagram

  B. Sales Insights

  C. Power Automate

  D. Security model

  Correct Answer: A

  Visual representation of metadata can be useful, especially when you are trying to describe the relationship between entities in the system. You can use the Metadata Diagram sample code provided for Dynamics 365 Customer Engagement (on-premises) to generate the entity relationship diagrams.

  You can create a diagram that shows a relationship for just one entity, or a complex diagram that includes dozens of related entities, including custom and system entities.

  Reference: https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/developer/use-metadata-generate-entity-diagrams

• Question 263:

  The communication department for a company plans to add a publicly accessible survey page to the company's public website.

  You must add the new survey page to the company's public website and capture data from the page to a Common Data Service environment.

  Explicit user credentials must not be required to write survey data to Common Data Service.

  You need to implement authentication.

  Which authentication mechanism should you implement?

  A. Microsoft 365

  B. X.509 certificate

  C. OAuth2.0

  D. Claims-based

  Correct Answer: C

  OAuth is the preferred means to authenticate because it provides access to both the OData RESTful web services (Web API and OData global Discovery service) as well as to the SOAP web services (Organization service and Discovery service).

  OAuth is also required to support:

  Azure Active Directory configurations for conditional access, such as Two-factor Authentication (2FA)

  Use of client secrets to enable server-to-server authentication scenarios. Cross-Origin Resource Sharing (CORS) to connect a Single-page Application (SPA)

• Question 264:

  You are creating a Power Apps app that retrieves customer information from Azure Active Directory when you use the app to look up a customer record.

  You create an Azure Function by using JSON code to retrieve the customer information.

  You need to make the application work.

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

  NOTE: Each correct selection is worth one point.

  A. Create a Power Automate flow to import data.

  B. Create a custom connector that uses the Azure Function API.

  C. Copy your JSON code to the app.

  D. Create a custom connector that uses the JSON code.

  E. Create an API definition for the Azure Function.

  Correct Answer: BE

  E: Before exporting an API, you must describe the API using an OpenAPI definition.

  B: This OpenAPI definition contains information about what operations are available in an API and how the request and response data for the API should be structured. PowerApps and Microsoft Flow can create custom connectors for any OpenAPI 2.0 definition.

• Question 265:

  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: Create a security role that has organization-level access to opportunities. Give this security role to all members of the two departments who need access.

  Does the solution meet the goal? role to all members of the two departments who need access.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead use access team templates and give access to members in the two departments.

• Question 266:

  A bank uses a Common Data Service solution to manage clients.

  Bank representatives perform client credit checks while the client is present. Credit checks may take up to five minutes to complete.

  Bank policy dictates that the bank representative's app must stay blocked until credit checks are complete.

  You need to display a model-driven app while credit checks run to ask the bank representative and client to

  wait for the credit check to complete.

  Which function should you use?

  A. Xrm.Navigation.openWebResource("prefix.myPoliteMessage.html")

  B. Xrm.Navigation.openAlertDialog(myPoliteMessage)

  C. Xrm.Utility.openWebResource("prefix_myPoliteMessage.html")

  D. Xrm.Utility.showProgressIndicator(myPoliteMessage)

  Correct Answer: D

  showProgressIndicator displays a progress dialog with the specified message.

  Any subsequent call to this method will update the displayed message in the existing progress dialog with the message specified in the latest method call.

  The progress dialog blocks the UI until it is closed using the closeProgressIndicator method. So, you must use this method with caution.

• Question 267:

  A travel company plans to track the address of places their clients visit in an entity named Destination. Client

  information is captured as contact records. Client records include links to the places that clients visit.

  The company must be able to link multiple rating records to the new address record.

  You find a custom Rating entity that is incomplete.

  You need to expand the Rating entity to include contact, address, and rating information in one place.

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

  NOTE: Each correct selection is worth one point.

  A. Create a 1:N relationship between the Contact system entity and the Address system entity named Destination.

  B. Create a mapping for the Contact – Rating relationship.

  C. Create a 1:N relationship between the Address system entity and the Rating entity.

  D. Create a 1:N relationship between the Contact system entity and the Rating entity.

  E. Create a mapping for the Destination – Rating relationship.

  F. Create a 1:N relationship between the Destination entity and the Rating entity.

  Correct Answer: ABC

  A: Each Contact can visit a destination many times.

  Note: A travel company plans to track the address of places their clients visit in an entity named Destination. Client information is captured as contact records. Client records include links to the places that clients visit.

  C (not D): The company must be able to link multiple rating records to the new address record.

  Each address entity can be linked to many rating records.

  B (not E): You need to expand the Rating entity to include contact, address, and rating information in one place.

  Need a mapping between for the Contact and Rating entities (through the Address/Destination entity).

  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:

  Write a SSIS package to connect to the source and target. Develop the SSIS package to find the records by the Modified on field. Create or update the records in the database instance based on results.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead enable change tracking for entities that will be synchronized, and use the Data Export Service to sync data between the database and Dynamics 365 Sales.

• Question 269:

  A multinational company requires that all phone numbers be standardized as country code + area code + phone number.

  The application design team decides that a custom PowerApps component framework (PCF) control should be used to prompt users for an area code and correctly format the phone number.

  You need to get the list of valid area codes when a contact record is opened and before the user enters a new phone number.

  In which function should you call webAPI.retrieveMultipleRecords?

  A. notifyOutputChanged

  B. init

  C. getOutputs

  D. updateView

  Correct Answer: D

  The updateView method will be called when any value in the property bag has changed. This includes field values, data-sets, global values such as container height and width, offline status, component metadata values such as label, visible, etc.

  Note: webAPI.retrieveMultipleRecords retrieves a collection of entity records.

  Incorrect Answers:

  notifyOutputChanged is a callback method to alert the framework that the control has new outputs ready to be retrieved asynchronously.

  getOutputs is called by the framework prior to a component receiving the new data. Returns an object based on nomenclature defined in manifest, expecting objects[s] for the property marked as bound.

• Question 270:

  A financial services company uses the Common Data Service (CDS) to develop solutions. The company uses development and production instances.

  You need to move solutions from the development instance to the production instance.

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

  NOTE: Each correct selection is worth one point.

  A. In the development instance, make changes to the solutions that are deployed in the production instance, export the solutions as managed solutions, and import the managed solutions into the production instance.

  B. In the development instance, highlight the solution you want to make changes to, select Clone a Patch, make changes, export the solution, and import the solution into the production instance.

  C. Export all managed solutions from the development instance and import the solutions into the production instance.

  D. In the production instance, import solutions with the same version number or higher when updating solutions.

  Correct Answer: AB

  A: When you import a managed solution, all component changes will be brought into the environment in a published state.

  B: You can apply patches to either managed or unmanaged solutions and include only changes to entities and related entity assets. Patches do not contain any non-customized system components or relationships that it dependents upon because these components already exist in the deployed-to organization. At some point in your development cycle, you can roll up all the patches into a new solution version to replace the original solution that the patches were created from.
