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

Question 1

A developer is creating a custom control using Power Apps Component Framework (PCF). After importing the solution, the control appears but does not show any data. What is the most likely issue based on the exhibit?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

The control requires a dataset property but only a text property is defined. The 'abilities' section indicates the control expects a dataset, but the only property defined is a single line of text. The control likely needs a dataset property to receive data. The version, namespace, and display key are not causing data issues.

Answer

The display-name-key is missing a translation

Answer

The version number is incorrect

Answer

The namespace is misspelled

Question 2

A user wants to build an app that allows field technicians to view work orders and capture photos offline. Which type of Power App should be chosen?

Accepted Answer

Canvas app with offline capability enabled.. Canvas apps can be enabled for offline use via the mobile app, allowing field technicians to view work orders and capture photos without connectivity. Option A is incorrect because Power Pages sites are public-facing websites, not designed for offline field worker scenarios. Option B is incorrect because AI Builder is a service for adding AI capabilities, not an app type; embedding it does not provide native offline support. Option C is incorrect because model-driven apps have limited offline capabilities and are not as flexible for offline data capture as canvas apps.

Answer

Power Pages site with offline access.

Answer

AI Builder model embedded in a canvas app.

Answer

Model-driven app because it natively supports offline.

Question 3

A company wants to create a Power App that allows employees to submit expense reports with receipts. The app must be accessible from both mobile devices and desktop browsers, and must include a workflow for approval. Which combination of Power Platform components should be used?

Accepted Answer

Canvas app with Power Automate flow triggered by form submission.. A canvas app is designed for responsive UI across mobile and desktop, making it suitable for both devices. Power Automate can be triggered from the canvas app (e.g., on form submission) to handle the approval workflow. Option B is incorrect because model-driven apps are not as flexible for custom mobile layouts. Option C is incorrect because AI Builder is not required for receipt processing in this scenario; while it could be used, it is not necessary. Option D is incorrect because Power Pages is for external-facing websites, not internal apps with approval workflows.

Answer

Model-driven app with embedded Power Automate flow for approval.

Answer

Canvas app with AI Builder to process receipts and Power Automate for approval.

Answer

Power Pages site with a custom workflow.

Question 4

A user reports that a canvas app is loading slowly. The app connects to a large SharePoint list with over 10,000 items. Which change would most improve performance?

Accepted Answer

Apply a delegable filter on the data source to limit records returned.. Delegation is the key to performance with large data sources. When a canvas app connects to SharePoint, operations that can be translated into a query (delegable) are processed server-side, returning only the necessary records. Applying a delegable filter (e.g., using '=' or 'StartsWith' on indexed columns) reduces the amount of data transferred and processed by the app, directly improving load time. Non-delegable operations force Power Apps to fetch the first 500 (or up to 2000) records and process them locally, which is slow and may miss data.

Answer

Increase the delegation limit to 10,000.

Answer

Add more screens to distribute the data.

Answer

Disable offline mode.

Question 5

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

Accepted Answer

Use of formulas like If, Switch, Filter. Option B is correct because canvas apps are built on Power Fx, a formula language that lets makers write expressions such as If, Switch, and Filter directly in property formulas, whereas model-driven apps rely on declarative configuration (forms, views, business rules) rather than a formula language. Option D is correct because canvas apps can call device and media capabilities through connectors and Power Fx functions (for example Camera, Location, and Barcode), giving them native access to hardware like the camera and GPS, while model-driven apps do not expose these device capabilities in the same way. Option A is incorrect because both canvas and model-driven apps can integrate with Microsoft Dataverse as their data source. Option C is incorrect because AI Builder models can be consumed from both canvas apps and model-driven apps. Option E is incorrect because embedding a canvas app inside a model-driven app is supported, so it is not exclusive to canvas apps.

Answer

Integration with Microsoft Dataverse

Answer

Ability to use AI Builder models

Answer

Embedding a canvas app in a model-driven app

Question 6

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 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 FetchXML query includes a filter on statecode equal to 0 (Active) and a condition on createdon within the last 30 days, and it specifies only the name, accountid, and createdon attributes. Therefore, it returns active accounts created in the last 30 days with only those three 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

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. Delegable queries push filtering and sorting operations to the data source (SharePoint) rather than pulling the entire dataset into Power Apps for client-side processing. This dramatically reduces the volume of data transferred and the memory footprint on the client, which is the primary cause of slow loads and timeouts. Non-delegable functions force Power Apps to retrieve the first 500 (or up to 2,000) records and process them locally, which breaks correctness and performance on large lists.

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 9

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 10

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. Microsoft Entra B2B (Business-to-Business) is Microsoft's feature for inviting external users as guest accounts into the organization's tenant, allowing them to authenticate with their own credentials while accessing internal resources. Configuring Microsoft Entra B2B guest user access enables external partners to sign in to Power Apps using their existing organizational identities. This matches the requirement exactly.

Answer

Use SharePoint external sharing settings

Answer

Enable anonymous access in Power Apps

Answer

Configure Azure AD B2C for the app

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

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

Accepted Answer

SharePoint Online. Option C (SharePoint Online) is correct because it is a cloud-based Microsoft 365 service that canvas apps connect to directly through the built-in SharePoint connector, with no on-premises data gateway required. Option E (Microsoft Dataverse) is correct because it is a native cloud data platform in Power Platform, and canvas apps use the standard Dataverse connector to access it directly without a gateway. Options A (SQL Server on-premises), B (SAP ERP on-premises), and D (Oracle database on-premises) are all on-premises systems, so reaching them from a canvas app requires an on-premises data gateway to bridge the cloud service to the local network.

Answer

SQL Server on-premises

Answer

SAP ERP on-premises

Answer

Oracle database on-premises

Question 13

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 in Power Apps model-driven apps are server-side/client-side logic components that can show, hide, enable, disable, or set field values based on conditions without writing code. They support conditional visibility tied to another field's value (e.g., show Approved only when Amount > 1000), and they run on both the form and the Dataverse layer. This makes them the correct no-code feature for the described requirement.

Answer

Form scripting

Answer

Workflow process

Answer

Power Automate flow

Question 14

Refer to the exhibit. An administrator wants to enforce a mobile app management policy that prevents screen capture in Power Apps. Which Microsoft service should the administrator use to deploy this policy?

Accepted Answer

Microsoft Intune. Microsoft Intune is the mobile device and application management (MDM/MAM) service in the Microsoft 365 stack, and it is where app protection policies are configured. An Intune app protection policy can enforce data-loss-prevention controls such as blocking screen capture, preventing copy/paste to unmanaged apps, and requiring a PIN, specifically for mobile apps like Power Apps on iOS and Android. This is the correct service to deploy the policy described.

Answer

Microsoft Entra ID

Answer

Microsoft Defender XDR

Answer

Microsoft Purview

Question 15

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. A canvas app is the right choice because it lets the maker design a custom, task-focused UI from scratch and connect directly to an existing SQL database via the SQL Server connector (or through a data gateway for on-premises SQL). Field technicians need a tailored mobile experience for logging service calls, which is exactly the canvas app design pattern. Model-driven apps require Dataverse as the data platform and are not designed to bind directly to an external SQL database as their primary source.

Answer

Power Automate flow

Answer

Model-driven app

Answer

Power Pages
