PL-900 Practice Test 20 — 15 Questions

Question 1

Which THREE components are part of a model-driven app? (Choose three.)

Accepted Answer

Form. In a model-driven app, Forms (C) provide the data entry interface, Dashboards (D) offer visual overviews of key metrics, and Business process flows (E) guide users through a defined process. Galleries (A) are components of canvas apps, not model-driven apps. Cloud flows (B) are automation tools in Power Automate and not part of the app UI.

Answer

Gallery

Answer

Cloud flow

Question 2

Which TWO data sources can be used with a canvas app? (Choose two.)

Accepted Answer

SharePoint list. SharePoint lists and Microsoft Dataverse are both valid data sources for canvas apps. SharePoint lists allow you to read and write data from SharePoint. Microsoft Dataverse is a scalable data platform that stores business data. The other options are not data sources: Microsoft Power Platform is the product family, Microsoft Teams is a collaboration app, and Power Automate is an automation service.

Answer

Microsoft Power Platform

Answer

Microsoft Teams

Answer

Power Automate

Question 3

Refer to the exhibit. The JSON describes a Power Apps function. Which call to this function will return a table of records where the 'Status' column equals 'Active'?

Accepted Answer

Filter(Accounts, Status = 'Active'). The Filter function in Power Apps takes the data source as the first argument and a formula as the second argument. Option B correctly uses Filter(Accounts, Status = 'Active'). Option A is incorrect because 'Active' alone is not a valid formula. Option C has the arguments reversed. Option D has the formula as the first argument and the source as the second, which is invalid.

Answer

Filter(Accounts, 'Active')

Answer

Filter('Active', Accounts)

Answer

Filter(Status = 'Active', Accounts)

Question 4

A company uses Power Apps to create a canvas app for employee expense reporting. The app needs to integrate with the corporate HR system to fetch employee details such as manager email and cost center. The HR system exposes a REST API that requires an API key in the header. Which approach should the app maker use to securely connect to the HR system?

Accepted Answer

Create a custom connector with API key authentication and use it in the app.. The correct approach is to create a custom connector with API key authentication. This securely stores the API key in the connector definition and allows the canvas app to call the HR system's REST API without exposing the key in the app code. Option A is wrong because a SharePoint list is not a REST API and cannot integrate with an external HR system. Option B is wrong because although Power Automate can call the API, it does not inherently provide a more secure way to handle the API key than a custom connector; the custom connector is specifically designed for this purpose within Power Apps. Option D is wrong because hardcoding the API key in the app's HTTP action headers exposes the key in the app code, which is not secure.

Answer

Store the HR data in a SharePoint list and connect the app to SharePoint.

Answer

Build a Power Automate flow that calls the API and returns data to the app.

Answer

Use the HTTP action in Power Apps to call the API and include the API key in the headers as a static value.

Question 5

A user creates a model-driven app for incident management. They want a custom button on the Incident form that, when clicked, creates a new activity record of type 'Phone Call' with the incident number in the subject. What is the recommended approach?

Accepted Answer

Add a custom ribbon button with a JavaScript command that uses Xrm.WebApi.createRecord.. Adding a custom ribbon button with a JavaScript command that uses Xrm.WebApi.createRecord allows creating a new activity record with specific values directly from the form. Option A is incorrect because business rules cannot create new records; they can only set field values or show/hide fields. Option B is incorrect because custom connectors are used for external APIs, not for standard Dataverse operations. Option C is incorrect because while Power Automate flows can create records, they require additional licensing and are more complex than a simple client-side script.

Answer

Define a business rule on the form that creates a new activity when the button is clicked.

Answer

Create a custom connector to the Dataverse API and use it in the app.

Answer

Use a Power Automate flow triggered from the button with a Dataverse 'Create a new record' action.

Question 6

Which TWO features are available in Canvas apps but NOT in model-driven apps? (Choose two.)

Accepted Answer

Custom connectors to external APIs. Options C and D are correct because Canvas apps allow custom connectors to external APIs and custom JavaScript/Power Fx formulas, while model-driven apps use predefined logic and connectors. Option A is wrong because both Canvas and model-driven apps can embed Power BI reports. Option B is wrong because both support Dataverse integration. Option E is wrong because both types support offline capability.

Answer

Embedding Power BI reports

Answer

Integration with Microsoft Dataverse

Answer

Offline capability

Question 7

Which TWO features are unique to model-driven apps compared to canvas apps? (Choose two.)

Accepted Answer

Business process flows. Options B and C are correct. Business process flows are unique to model-driven apps; they provide a guided workflow. Responsive design that adapts to screen size is built into model-driven apps, while canvas apps require manual layout adjustments. Option A is incorrect because custom controls from Microsoft AppSource are available for both canvas and model-driven apps. Option D is incorrect because Power Fx formulas are primarily used in canvas apps (model-driven apps use forms and views with limited formula support). Option E is incorrect because offline capability can be configured in both canvas and model-driven apps.

Answer

Custom controls from Microsoft AppSource

Answer

Power Fx formulas

Answer

Offline capability

Question 8

You are designing a Power Apps solution for a global sales team. The app must display data in the user's local time zone. The data is stored in Dataverse in UTC. What is the best practice for time zone handling?

Accepted Answer

Store times in UTC and let Power Apps handle conversion automatically. The best practice is to store times in UTC and let Power Apps handle the conversion to the user's local time zone automatically based on their browser or device settings. This ensures consistency across global users and avoids errors from manual conversion or storing local times. Option A is error-prone due to complex formulas, option C causes confusion because the same record would show different times for different users, and option D adds unnecessary complexity.

Answer

Convert UTC to each time zone using Power Fx formulas

Answer

Store local time in the database based on user's location

Answer

Use a Power Automate flow to convert time zones

Question 9

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 10

A company wants to create a mobile app for field technicians to log service calls. The app will connect to an existing SQL database. Which type of Power App should they build?

Accepted Answer

Canvas app. Canvas apps allow custom layout and connectivity to many data sources like SQL, ideal for mobile scenarios. Option A is wrong because Power Automate is for automation, not app building. Option B is wrong because model-driven apps are form-centric and designed for complex business processes. Option C is wrong because Power Pages is for external-facing websites.

Answer

Power Automate flow

Answer

Model-driven app

Answer

Power Pages

Question 11

Which THREE are capabilities of model-driven apps?

Accepted Answer

Business process flows to guide users through steps. Options A, D, and E are correct. Model-driven apps include business process flows to guide users, server-side logic via classic workflows or Power Automate, and business rules to enforce field behavior. Option B is incorrect because custom CSS is not a capability; model-driven apps use responsive design. Option C is incorrect because pixel-perfect drag-and-drop layout is a canvas app feature.

Answer

Custom CSS to style the app

Answer

Pixel-perfect layout design using drag and drop

Question 12

Which THREE components are required to build a model-driven app in Power Apps? (Choose three.)

Accepted Answer

View. Options A, B, and C are correct because a model-driven app requires a Microsoft Dataverse database, tables (entities) to store data, and views to display data. Option D is incorrect because canvas apps are a different type of app, not a component of a model-driven app. Option E is incorrect because Power Automate flows are optional and not required components.

Answer

Canvas app component

Answer

Power Automate flow

Question 13

Refer to the exhibit. An administrator sees this JSON output from a Power Apps management command. The administrator needs to change the owner of the app to another user. Which tool should they use?

Accepted Answer

Power Platform admin center. The Power Platform admin center provides the environment-level management capabilities needed to change app ownership. Option A is incorrect because Power Apps PowerShell cmdlets can also change ownership, but the admin center is the recommended and more accessible tool for non-scripting administrators. Option C is incorrect because Power Apps Studio is used for designing and editing apps, not for administrative tasks like changing ownership. Option D is incorrect because Azure portal is used for managing Azure resources, not Power Apps administration.

Answer

Power Apps PowerShell cmdlets

Answer

Power Apps Studio

Answer

Azure portal

Question 14

Which TWO of the following data sources can be used directly in a canvas app without using a gateway? (Choose TWO.)

Accepted Answer

Dataverse. The correct answers are D (Dataverse) and E (SharePoint Online). Both are cloud-based data sources that can be directly accessed in a canvas app without needing an on-premises data gateway. On-premises data sources such as SQL Server, Oracle Database, and SAP HANA (options A, B, and C) require a gateway to connect from a cloud canvas app.

Answer

On-premises SQL Server

Answer

On-premises Oracle Database

Answer

On-premises SAP HANA

Question 15

Refer to the exhibit. You are designing a Power Automate flow that receives an HTTP request with a JSON body. You use the 'Parse JSON' action with the schema shown. The flow fails when the incoming JSON contains an 'items' array with a product object missing the 'quantity' field. What is the best way to fix this?

Accepted Answer

Remove 'quantity' from the required array inside the items schema.. The schema defines 'quantity' as required in each item. To make it optional, you should remove it from the 'required' array inside the items schema. Option B is wrong because the 'items' array itself is not required. Option C is wrong because changing the type to 'string' is incorrect. Option D is wrong because the issue is in the child object, not the parent.

Answer

Add 'items' to the top-level required array.

Answer

Change the type of 'quantity' to 'string'.

Answer

Remove the 'required' array from the top level.
