Question 156

You are mapping data from an enterprise resource planning (ERP) system to Microsoft Dataverse. You must reference the Name and Email from the ERP system during mapping to ensure that records are unique. You need to create an alternate key that references the Name and Email columns. How should you create the key?

Question 91

You create a custom API. You define the API as a function. The custom API does not appear in the response received from https://[yourorg].api.crm.dynamics.com/api/data/v9.2/$metadata and returns an error when called. You need to identify why the custom API is not working. What should you do?

Question 49

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. 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 on the review screen. You are designing an integration that sends created records from a custom Dataverse table to an exposed REST API. When the REST API is unavailable, you must be able to retry if the response status code is 500. You need to select a solution that meets the requirement. Solution: Register a service endpoint for an Azure Service Bus queue. Use an Azure Function to process messages from the queue and forward them to the REST API. Redirect failed messages to the dead-letter queue. Does the solution meet the goal?

Question 38

The company subsidizes home improvements for domestic customers, to improve energy efficiency and to meet environmental commitments. The company also distributes and generates electricity for domestic and commercial customers. The company has 2,000 employees in multiple offices and in work-from-home locations. City Power & Light uses a team of schedulers, assessors, field engineers, and customer support agents for home improvements in a program named Get Energy Fit. Current Environment - Get Energy Fit Program - City Power & Light uses the following to manage the Get Energy Fit program: • The company uses a Microsoft Excel spreadsheet named Planning Hub on Microsoft SharePoint Online to store information about customer appointments, customer details, and customer eligibility in the program. • The company records sensitive customer information that includes the document identification numbers and the customer's financial information. • The company uses an assessor to verify customer eligibility in the program and to perform a suitability assessment. The assessor completes the suitability assessment by using a paper and clipboard at the customer property and enters the data to the Planning Hub after the assessment is completed. The assessor also uploads photographs to an on-premises document library. The assessor completes the eligibility assessment by using an application written in React. • Schedulers use Microsoft Outlook to schedule engineers and assessors for home improvement appointments. About 200 appointments are scheduled daily. • Employees for the company submit funding claims on behalf of the customer by uploading evidence and compliance checks information to an application named the Claim Submission Portal. Technical Environment - • Schedulers use Windows 11 desktop and laptop computers with the latest version of Microsoft Edge. • Assessors use iOS and Android tablet devices. • The Claim Submission Portal uses REST-based APIs for all operations and a dedicated testing environment. Authentication to the API is provided by using the following example header key and value pair: o Authentication: 2C8D41431415E429C7FC7A74D8315 • The company uses Microsoft Azure for hosting multiple applications. Requirements - Overview - City Power & Light plans to implement Microsoft Power Platform to improve the customer experience and increase delivery for the Get Energy Fit program. Business Requirements - • Only team leaders and senior managers should have access to read personally identifiable information (PII). • All development changes must be tested in a separate environment. • The company requires out-of-the-box solutions, when possible. • Sensitive credentials, such as user passwords and API secrets, must be stored securely. • The Claim Submission Portal must allow citizen developers to create automated solutions. • Customer and appointment information must be accessible to all applications. Planning Hub Application - The company is planning to replace the Planning Hub spreadsheet with a new application. The new application has the following requirements: • The application must support a component design that provides rapid changes requested by the schedulers. • The data model for the application must capture the following information: o Information about customers such as name, address, and other PII. o The data and time for an assessor's or engineer's appointment. Schedulers must be able to view all appointments without filters. o Records the details of the home improvements installed for the customer. o Contains all the information and evidence for submission to the Claim Submission Portal. • After an assessor uploads the funding application and all evidence after a home improvement has been complete, the company requires that the status of the application is set to Submit and should run the following: o Retrieve the details about the customer and the improvement installed. o Send an approval to a senior manager to review and approve in Microsoft Teams. o Upload the information to the API endpoint. o If the upload fails to complete, it should retry after a delay of 30 seconds up to three times. If an error occurs after three times, the application should send an email notification to the application support team. o Must record the status on the funding application. Suitability Assessment Tool - The company plans to implement a new application named the Suitability Assessment Tool for the assessors. The new application has the following requirements: • Must integrate with Microsoft Power Platform. • Assessors must be able to complete the eligibility assessment by using the Suitability Assessment Tool. The assessors must be able to upload photographs to the on-premises file share. • Must be developed by using modular components that can be used by other applications. • Must be optimized for use on tablet devices. • All changes to the application must be completed in the Suitability Assessment Tool solution. Reporting - The company has the following requirements for a reporting solution: • The data source for the reporting solution must support incremental refreshes. • The solution must report accurate data if an error occurs. Issues - • A recent audit identified that all users can access the PII in the Planning Hub spreadsheet. • After a developer deploys a change to the production environment, a user reports information is loaded incorrectly to the test system when processing a funding application. • After deploying a change to the new eligibility assessment tool in the development environment, you observe that the changes do not appear in the development environment. • After removing a column from the Planning Hub application and deploying the changes to the production environment, you observe that the column is still present. • You deploy the customizations for the data model. Users report that the email address of the user who created the appointment is missing and that searches on the description information do not return any results. You need to resolve the issue with the eligibility assessment tool. Which two commands should you run? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

Question 44

DRAG DROP - You are designing an implementation that has complex data requirements. The data storage requirements are as follows: • Query large amounts of unstructured data in Dataverse. • Read and update structured data stored outside of Dataverse. You need to implement data storage to meet the requirements. Which table types should you use? To answer, move the appropriate table types to the correct data storage requirements. You may use each table type once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.

Question 297
