PL-900 Demonstrate the capabilities of Power Apps Practice Test 10 — 15 Questions

Question 1

A model-driven app for project management uses a custom entity 'Project' with a status field. The app maker wants to show a timeline of project phases using a timeline control. What must be configured for the timeline to display correctly?

Accepted Answer

Create an activity entity for project phases and relate it to the Project entity.. The timeline control requires a relationship to an activity entity (like Appointment) or a custom entity configured as an activity. Option A is wrong because the timeline does not require a specific field. Option B is wrong because timeline does not use subgrid. Option D is wrong because timeline is not a standard SharePoint integration.

Answer

Add a subgrid of project phases and configure it as a timeline.

Answer

Set the timeline control's date field to the project start date.

Answer

Integrate with Microsoft Project for timeline data.

Question 2

Which TWO features are available in canvas apps but NOT in model-driven apps?

Accepted Answer

Use of formulas like If, Switch, Filter. Canvas apps allow custom formulas and mobile device features (camera, GPS). Model-driven apps do not have formula-based logic; they use business rules/processes. Option A is available in both. Option B is available in both (embedded canvas). Option D is not a feature.

Answer

Integration with Microsoft Dataverse

Answer

Ability to use AI Builder models

Answer

Embedding a canvas app in a model-driven app

Question 3

Which THREE actions can be performed by using Power Apps component framework (PCF) in a model-driven app?

Accepted Answer

Implement data validation using Dataverse Web API. Option B is correct because Power Apps component framework (PCF) allows developers to create custom components that can interact with the Dataverse Web API to perform data validation. This is achieved by using the `context.webAPI` methods within a PCF component, enabling server-side validation logic beyond simple client-side scripts.

Answer

Add a client-side script that runs on field change

Answer

Change the layout of the main form using drag and drop

Answer

Configure a business rule to set field values

Question 4

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 role-based security out of the box and consistent UI across devices. Option C is true for canvas apps too. Option D is not a benefit; model-driven apps are not easily customizable. Option E is not a benefit; canvas apps have more formulas.

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 5

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 wrong because there is no update. Option B is wrong because it is not creating. Option D is wrong because it is not deleting.

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 6

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 is a GUID that uniquely identifies the environment in Dataverse. Option A is wrong because it's not a connector. Option B is wrong because it's not a workspace. Option D is wrong because it's not a license key.

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 7

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 8

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. Option C is correct because Power Apps mobile app supports offline capabilities by caching data and syncing when connectivity is restored. Option A is wrong because canvas apps require connectivity for initial load but can be configured for offline use; however, the question asks about the capability that enables offline, which is the mobile app's offline sync feature. Option B is wrong because model-driven apps also support offline, but the best answer is the mobile app feature. Option D is wrong because the Common Data Service (now Microsoft Dataverse) provides offline sync, but the capability is accessed through the Power Apps mobile app.

Answer

Canvas apps from Power Apps Studio

Answer

Microsoft Dataverse offline profiles

Answer

Model-driven apps

Question 9

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. Option B is correct because delegating data operations to the data source reduces the amount of data retrieved and processed client-side, improving performance. Option A is wrong because increasing timeouts does not address the root cause. Option C is wrong because splitting into multiple screens may help but does not solve delegation issues. Option D is wrong because using SQL Server might help but is not a direct solution; the question is about improving performance without changing data source.

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 10

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. Option A is correct because canvas apps allow building from a blank canvas or template with a drag-and-drop interface, requiring minimal code. Option B is wrong because model-driven apps are more structured and require Dataverse. Option C is wrong because Power Automate is for workflows. Option D is wrong because Power Pages is for external websites.

Answer

Power Pages site

Answer

Model-driven app

Answer

Power Automate flow

Question 11

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. Option B is correct because the HTTP with Azure AD connector can call any REST API and supports authentication. Option A is wrong because SharePoint connector is for SharePoint lists. Option C is wrong because SQL Server connector is for SQL databases. Option D is wrong because Office 365 Users connector is for user profiles, not custom APIs.

Answer

Office 365 Users connector

Answer

SQL Server connector

Answer

SharePoint connector

Question 12

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. Option C is correct because using delegable filters ensures that only relevant data is retrieved, reducing load. Option A is wrong because removing filters could increase data load. Option B is wrong because increasing the data row limit in Dataverse may not help; the issue is delegation. Option D is wrong because using a different data source is not allowed.

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 13

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. Option B is correct because 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 14

An organization plans to build a Power App that will be used by external partners. The app must allow partners to log in with their own credentials (Azure AD B2B). Which feature should be configured?

Accepted Answer

Set up Azure AD B2B guest user access. Option C is correct because Azure AD B2B enables external users to use their own identities. Option A is wrong because the app is for partners, not anonymous. Option B is wrong because Azure AD B2C is for customer identities, not B2B. Option D is wrong because SharePoint external sharing is for SharePoint, not Power Apps authentication.

Answer

Use SharePoint external sharing settings

Answer

Enable anonymous access in Power Apps

Answer

Configure Azure AD B2C for the app

Question 15

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. Option D is correct because OAuth 2.0 client credentials is a standard OAuth flow. Option A is wrong because API Key is a different mechanism. Option B is wrong because Basic authentication is not OAuth. Option C is wrong because Windows Authentication is not OAuth.
