PL-900 Demonstrate the capabilities of Power Apps Practice Test 3 — 15 Questions

Question 1

A company wants to build a canvas app to allow field technicians to report equipment issues from their mobile devices. The app must work offline and sync data when connectivity is restored. Which feature should the developer use?

Accepted Answer

Offline. Option B is correct because Power Apps canvas apps support offline capability using the Offline feature, which caches data on the device and syncs when connectivity returns. Option A is wrong because the Common Data Service (now Microsoft Dataverse) is a data platform but does not directly provide offline capabilities; the Offline feature sets up sync. Option C is wrong because the Power Platform admin center is for administration. Option D is wrong because Power Automate flows can be part of the solution but are not the offline feature itself.

Answer

Power Automate

Answer

Power Platform admin center

Answer

Common Data Service

Question 2

A team is creating a model-driven app to manage customer service cases. They want to ensure that only users with a specific security role can delete cases. What should they configure?

Accepted Answer

Security roles. Option B is correct because security roles in model-driven apps define permissions, including delete rights. Option A is wrong because business rules define logic, not permissions. Option C is wrong because the app's properties do not include security settings. Option D is wrong because the SharePoint connector is for integration, not security.

Answer

Business rules

Answer

SharePoint connector

Answer

App properties

Question 3

A user reports that a canvas app displays an error: 'The data source is not found.' The app connects to a SQL Server database via an on-premises data gateway. The gateway status shows 'Running' and the connection is configured. What is the most likely cause?

Accepted Answer

The SQL table name in the app formula is incorrect. Option D is correct because the app's query could be referencing a table name that does not exist or is misspelled. Option A is wrong because the gateway is running. Option B is wrong because a missing environment variable would cause a different error. Option C is wrong because a SharePoint list deletion would not affect SQL Server connections.

Answer

A required environment variable is missing

Answer

A SharePoint list used in the app was deleted

Answer

The on-premises data gateway is offline

Question 4

An organization needs to create a form for employees to submit vacation requests. The form should automatically calculate the number of days requested based on the start and end dates. Which type of app should they build?

Accepted Answer

Canvas app. Option B is correct because canvas apps provide flexible formulas to calculate values like date differences. Option A is wrong because model-driven apps use forms but custom calculations are less straightforward. Option C is wrong because portals are for external users. Option D is wrong because Power Automate is for automation, not app building.

Answer

Power Apps portal

Answer

Power Automate

Answer

Model-driven app

Question 5

A company wants to build a Power Apps solution that integrates with Microsoft Teams. They want to embed the app directly into a Teams channel. Which type of app should they build?

Accepted Answer

Canvas app. Option A is correct because canvas apps can be embedded in Teams using the Power Apps app in Teams. Option B is wrong because model-driven apps are not directly embedded in Teams. Option C is wrong because AI Builder is for AI models, not app embedding. Option D is wrong because Power Virtual Agents are chatbots.

Answer

AI Builder

Answer

Model-driven app

Answer

Power Virtual Agents

Question 6

A developer is troubleshooting a canvas app that uses a SharePoint list as a data source. The app works for some users but fails for others with the error 'Access denied.' All users have read access to the SharePoint list. What could be the issue?

Accepted Answer

The users do not have permissions to the SharePoint list. Option D is correct because Power Apps uses the user's own permissions to access SharePoint. Even if the app is shared, the underlying data permissions must be correct. Option A is wrong because licenses are not the issue here. Option B is wrong because the user environment is the same for all. Option C is wrong because the list is not set to private if users have read access.

Answer

The SharePoint list is set to private

Answer

The users do not have Power Apps licenses

Answer

The app is in a different environment than the users

Question 7

An organization wants to build a Power Apps solution that uses AI to extract information from invoices automatically. Which feature should they use?

Accepted Answer

AI Builder. AI Builder is the correct feature because it provides prebuilt and custom AI models that can be trained to extract structured data from documents like invoices. It integrates directly into Power Apps, allowing users to add AI-powered invoice processing without writing code or managing machine learning infrastructure.

Answer

Power BI

Answer

Power Automate

Answer

Common Data Service

Question 8

A user wants to edit the fields displayed in a model-driven app form. Where should they go to customize the form?

Accepted Answer

Power Apps maker portal. Option C is correct because model-driven app forms are customized using the form designer in Power Apps (make.powerapps.com). Option A is wrong because the app is the runtime view. Option B is wrong because SharePoint list settings are unrelated. Option D is wrong because Power Automate is for automation.

Answer

From the app itself by selecting Edit

Answer

Power Automate

Answer

SharePoint list settings

Question 9

A canvas app includes a gallery that shows a list of customers. The app loads slowly when the gallery displays more than 500 records. What is the best way to improve performance?

Accepted Answer

Apply a filter to the gallery data source. Option B is correct because using a filter to reduce the number of records loaded improves performance. Option A is wrong because increasing the gallery height does not affect data loading. Option C is wrong because delegable queries only work with certain data sources; for non-delegable sources, filtering is best. Option D is wrong because moving to a model-driven app is a redesign, not a simple fix.

Answer

Use a non-delegable query

Answer

Convert the app to a model-driven app

Answer

Increase the gallery height

Question 10

Which TWO components are required to create a model-driven app in Power Apps? (Choose two.)

Accepted Answer

Dataverse table. Dataverse tables (Option B) are the fundamental data storage structure for model-driven apps. Every model-driven app must be built on top of at least one Dataverse table to provide the data schema, relationships, and security context that the app's views, forms, and dashboards rely on. Without a Dataverse table, the app has no data source to interact with.

Answer

AI Builder model

Answer

Power Automate flow

Answer

Power BI dashboard

Question 11

Which THREE are valid data sources for a canvas app? (Choose three.)

Accepted Answer

SharePoint list. Option A is correct because SharePoint lists are supported. Option C is correct because SQL Server is supported. Option D is correct because Excel files stored in OneDrive are supported. Option B is wrong because Azure DevOps is not a direct canvas app data source (use connectors). Option E is wrong because Power BI datasets are not data sources; you can embed reports but not use as source.

Answer

Azure DevOps work items

Answer

Power BI dataset

Question 12

Which TWO capabilities does Power Apps provide? (Choose two.)

Accepted Answer

Implementing business process flows. Option B is correct because canvas apps allow custom layouts. Option D is correct because model-driven apps provide business process flows. Option A is wrong because Power Apps does not create Power BI dashboards natively. Option C is wrong because Power Automate handles scheduled automations. Option E is wrong because AI Builder is a separate add-on, not a core capability of Power Apps.

Answer

Creating Power BI dashboards

Answer

Scheduling automated workflows

Answer

Training custom AI models

Question 13

A company wants to build a Power App that allows sales representatives to capture customer feedback offline on their mobile devices. The feedback includes text, images, and signature. Which feature should be used to handle offline image and signature capture?

Accepted Answer

Use a canvas app with offline capability and the Camera and Signature controls, syncing to Dataverse when online. Option C is correct because Power Apps mobile offline capability allows forms and images to be captured offline and synced later. Option A is wrong because Canvas apps with offline capability require the app to be designed for offline use, but images and signatures are supported. Option B is wrong because the Common Data Service (now Microsoft Dataverse) offline sync supports image and signature fields. Option D is wrong because SharePoint integration requires connectivity.

Answer

Use a SharePoint list with Power Apps integration for offline data capture

Answer

Use a canvas app with the Offline template and store data in Dataverse

Answer

Use a model-driven app with Dataverse offline sync

Question 14

A business analyst wants to create a simple expense report app without writing code. The app should allow users to submit expenses and managers to approve or reject them. Which type of Power App should the analyst use?

Accepted Answer

Canvas app. Option B is correct because canvas apps start from a blank canvas or template and allow drag-and-drop design for simple forms. Option A is wrong because model-driven apps are more complex and require Dataverse. Option C is wrong because Power Pages are external-facing websites. Option D is wrong because Copilot Studio is for chatbots.

Answer

Power Pages

Answer

Copilot Studio

Answer

Model-driven app

Question 15

A Power App connected to Dataverse uses a column of type 'Choice' with two options: 'Active' and 'Inactive'. The app needs to display only active records by default. Which filter expression should be used in the app's OnStart property?

Accepted Answer

Filter(Accounts, Status = 'Active'). Option A is correct because the filter syntax is Filter(EntityName, ColumnName = 'Value'). Option B is wrong because the syntax is incorrect (wrong quotes). Option C is wrong because it uses double quotes instead of single quotes for the Choice value. Option D is wrong because it uses double quotes for the field name.

Answer

Filter(Accounts, "Status" = 'Active')

Answer

Filter(Accounts, Status = "Active")

Answer

Filter(Accounts, Status = 'Active')
