Question 1

Which TWO are benefits of using model-driven apps over canvas apps for enterprise data management?

Accepted Answer

Responsive design that automatically adapts to screen size. Model-driven apps provide built-in role-based security and responsive design that adapts to screen size, making them ideal for enterprise data management. Option A is correct because model-driven apps automatically adapt to different devices without extra effort. Option E is correct because they inherit Dataverse role-based security. Option B is incorrect because offline capability is more commonly associated with canvas apps. Option C is incorrect because custom connectors are available in both app types. Option D is incorrect because canvas apps are better suited for complex formulas with Power Fx.

Answer

Ability to work offline on mobile devices

Answer

Support for custom connectors to external systems

Answer

Easier to create complex formulas and logic

Question 2

You are reviewing a Power Automate flow that uses an Office 365 Users connector. The exhibit shows a JSON definition of an action. What does this action do?

Accepted Answer

Retrieves the user profile of the record owner.. The action uses the GetUserProfile operation with a User parameter taken from the trigger output. It retrieves the profile of the user who is the owner of the triggering record. Option A is incorrect because the action does not perform an update; it only retrieves data. Option B is incorrect because the action does not delete a profile. Option C is incorrect because the action does not create a new profile. Therefore, option D is correct.

Answer

Updates the profile of the user who triggered the flow.

Answer

Deletes the user profile of the record owner.

Answer

Creates a new user profile in Office 365.

Question 3

You are troubleshooting a Power Apps issue. Using PowerShell, you run Get-AdminPowerApp and see the exhibit output. What does the EnvironmentName field indicate?

Accepted Answer

The unique identifier of the Dataverse environment hosting the app.. The EnvironmentName field in Get-AdminPowerApp output is a GUID that uniquely identifies the Dataverse environment where the app is hosted. Option A is incorrect because it is not a license key; Option C is incorrect because it is not a custom connector name; Option D is incorrect because it is not a SharePoint site name. Only Option B correctly describes the field.

Answer

The license key for Power Apps.

Answer

The name of the custom connector used by the app.

Answer

The name of the SharePoint site where the app is stored.

Question 4

You are reviewing a FetchXML query used in a Power Apps component. The exhibit shows the query. What data will this query return?

Accepted Answer

Active accounts created in the last 30 days, returning name, accountid, and createdon.. The query selects accounts where statecode equals 0 (Active) and createdon is within the last 30 days. It returns name, accountid, and createdon. Option A is wrong because statecode 0 is Active, not Inactive. Option B is wrong because it's not all accounts. Option D is wrong because it does not include all attributes.

Answer

All inactive accounts created in the last 30 days, including all attributes.

Answer

All accounts created in the last 30 days, only name, accountid, and createdon.

Answer

All accounts regardless of state, returning all attributes.

Question 5

A company wants to build a mobile app for field service technicians to view and update work orders. The app must work offline when technicians are in areas with no connectivity. Which Power Apps capability should the developer use?

Accepted Answer

Power Apps mobile app with offline sync. The Power Apps mobile app includes built-in offline sync capabilities that allow field service technicians to view and update work orders even when there is no network connectivity. Data is cached locally and synchronized with the server once connectivity is restored. Option A is incorrect because while canvas apps can be configured for offline use, the question specifically asks about the capability that enables offline functionality, which is the mobile app's offline sync feature rather than the development tool. Option B is incorrect because Microsoft Dataverse offline profiles are a configuration option within Dataverse, but the enabling feature for offline use in Power Apps is the mobile app itself. Option C is incorrect because model-driven apps rely on Dataverse and can support offline, but again, the key capability that makes offline possible is the Power Apps mobile app's offline sync, not the app type.

Answer

Canvas apps from Power Apps Studio

Answer

Microsoft Dataverse offline profiles

Answer

Model-driven apps

Question 6

An organization has a canvas app that uses a SharePoint list as its data source. Users report that the app loads slowly and sometimes times out. The developer needs to improve performance. Which approach should the developer take?

Accepted Answer

Use delegable queries to filter data at the source. Using delegable queries allows the data source to filter data before sending it to the app, reducing the amount of data transferred and improving performance. Option A is wrong because increasing timeouts does not address the root cause of slow loading. Option B is wrong because migrating to SQL Server is an unnecessary and costly change; the issue can be resolved within the current data source by using delegation. Option C is wrong because splitting into multiple screens does not reduce the data load per screen if queries are not delegable.

Answer

Increase the timeout setting in the app settings

Answer

Migrate the data source to SQL Server to improve performance

Answer

Split the app into multiple screens to reduce load per screen

Question 7

A business analyst wants to create a simple app to track employee vacation requests without writing code. Which type of Power App should they use?

Accepted Answer

Canvas app from a template. Canvas apps from templates provide a low-code or no-code way to build apps with a drag-and-drop interface, ideal for simple tasks like tracking vacation requests. Option A is wrong: Power Pages is for building external-facing websites, not internal apps. Option B is wrong: Model-driven apps are more complex and rely on Dataverse, requiring more structure than needed. Option D is wrong: Power Automate is for automating workflows, not for building interactive apps.

Answer

Power Pages site

Answer

Model-driven app

Answer

Power Automate flow

Question 8

A company has a legacy system that exposes a REST API. They want to build a Power App that displays data from this API and allows users to update records. Which connector should they use?

Accepted Answer

HTTP with Azure AD connector. The HTTP with Azure AD connector can call any REST API and supports authentication, making it suitable for integrating with a legacy system that exposes a REST API. Option B is wrong because the Office 365 Users connector is designed for retrieving user profiles from Microsoft 365, not for calling custom REST APIs. Option C is wrong because the SQL Server connector is used to connect to SQL databases, not REST APIs. Option D is wrong because the SharePoint connector is intended for interacting with SharePoint lists and documents, not for consuming REST APIs.

Answer

Office 365 Users connector

Answer

SQL Server connector

Answer

SharePoint connector

Question 9

An app maker creates a canvas app that uses a Dataverse table with 100,000 records. The app includes a gallery that displays all records. Users experience long load times. What should the app maker do to improve performance without changing the data source?

Accepted Answer

Use delegable functions in the gallery's Items property. Using delegable functions (such as Filter, Sort, LookUp) in the gallery's Items property allows the query to be processed on the Dataverse server, returning only the necessary subset of records. This significantly reduces the amount of data transferred and improves performance for large datasets like 100,000 records. Option B is incorrect because it involves changing the data source, which is not allowed per the question. Option C is incorrect because increasing the data row limit in Dataverse settings does not address the delegation issue and may even worsen performance. Option D is incorrect because removing filters would cause the entire dataset to be loaded, making load times even longer.

Answer

Switch to a SharePoint list as the data source

Answer

Increase the data row limit in Dataverse settings

Answer

Remove all filters from the gallery

Question 10

A user needs to create an app that shows data from a SQL Server database and allows users to edit records. The user has no coding experience. Which Power Apps approach should they use?

Accepted Answer

Use the Power Apps template for SQL Server. The Power Apps template for SQL Server provides a ready-made app that can be connected to a database. Option A is wrong because model-driven apps require Dataverse. Option C is wrong because starting from blank is more complex. Option D is wrong because Power Automate is for automation.

Answer

Create a model-driven app

Answer

Start from blank canvas and use SQL Server connector

Answer

Use Power Automate to create a user interface

Question 11

A developer builds a canvas app that uses a custom connector to call an external API. The API requires an OAuth 2.0 client credentials flow. Which authentication type should the developer configure in the custom connector?

Accepted Answer

OAuth 2.0. OAuth 2.0 client credentials flow is a standard OAuth flow used for server-to-server authentication where no user is involved. Option B is incorrect because Windows Authentication is not OAuth-based and does not support client credentials flow. Option C is incorrect because API Key is a simple token-based authentication, not OAuth. Option D is incorrect because Basic Authentication sends credentials in plaintext and is not OAuth 2.0.

Answer

Windows Authentication

Answer

API Key

Answer

Basic Authentication

Question 12

A company wants to build a Power App that can be used on mobile devices and tablets. They need the app to adapt to different screen sizes. Which feature should they use?

Accepted Answer

Responsive layout containers. Power Apps responsive layout containers allow controls to automatically resize and reposition. Option A is wrong because static layouts do not adapt. Option C is wrong because the mobile app does not automatically adapt layouts. Option D is wrong because screen templates are fixed.

Answer

Power Apps mobile app with no changes

Answer

Use of screen templates only

Answer

Static layout with fixed sizes

Question 13

Which TWO Power Apps features allow sharing apps with users who have a Power Apps per app plan?

Accepted Answer

Sharing the app with a security group. Sharing an app with a security group allows you to assign per app plan licenses to all members of that group. Option C is correct because you must assign per app plan licenses to users explicitly to grant access. Option A is incorrect because adding users as co-owners does not provide them with a license; they still need a per app plan or per user plan. Option D is incorrect because granting Dataverse access does not include a Power Apps license. Option E is incorrect because sharing with everyone in the organization requires a per user plan or different licensing agreement.

Answer

Adding users as co-owners of the app

Answer

Granting Dataverse access to users

Answer

Sharing the app with everyone in the organization

Question 14

Which TWO data sources can be directly connected to a canvas app without using an on-premises data gateway?

Accepted Answer

SharePoint Online. Options C and E are correct because SharePoint Online and Microsoft Dataverse are cloud-based data sources that can be directly connected to canvas apps without an on-premises data gateway. Options A, B, and D are incorrect because SQL Server on-premises, SAP ERP on-premises, and Oracle database on-premises all require an on-premises data gateway to connect.

Answer

SQL Server on-premises

Answer

SAP ERP on-premises

Answer

Oracle database on-premises

Question 15

Refer to the exhibit. A developer is creating a model-driven app based on a custom Dataverse table defined by this JSON. The app needs a form that shows the Approved field only when the amount is greater than 1000. Which feature should the developer use?

Accepted Answer

Business rule. Business rules can show or hide fields based on conditions without requiring code. Option A is correct because business rules are designed for declarative logic in model-driven apps, such as showing the Approved field only when Amount > 1000. Option B is incorrect because form scripting requires JavaScript, which is not necessary here. Option C is incorrect because workflow processes handle backend logic, not form behavior. Option D is incorrect because Power Automate flows are for automation outside of forms.

Answer

Form scripting

Answer

Workflow process

Answer

Power Automate flow
