PL-900 Demonstrate the capabilities of Power Apps Practice Test 9 — 15 Questions

Question 1

Which THREE of the following are capabilities of Power Apps?

Accepted Answer

Use AI Builder to add artificial intelligence. Power Apps allows users to connect to Microsoft 365 data (e.g., SharePoint, Outlook) for building business applications. It also integrates with AI Builder to add artificial intelligence capabilities. Additionally, Power Apps can run on mobile devices (iOS, Android, Windows) through the Power Apps mobile app. Option A is incorrect because complex workflow automations are a capability of Power Automate, not Power Apps. Option B is incorrect because real-time streaming analytics is not a core capability of Power Apps; it is more aligned with Azure Stream Analytics or Power BI.

Answer

Create complex workflow automations

Answer

Perform real-time streaming analytics

Question 2

Which TWO of the following are types of apps you can create with Power Apps?

Accepted Answer

Canvas app. Canvas apps allow you to design a custom user interface by dragging and dropping elements onto a blank canvas, giving you full control over the layout and appearance. They connect to a wide range of data sources, such as SharePoint, Excel, or SQL Server, and are ideal for building task-specific or role-specific applications quickly.

Answer

Power Automate

Answer

Portal app

Answer

Web app

Question 3

Refer to the exhibit. You are configuring a conditional access policy in Microsoft Entra ID to restrict access to Microsoft 365 services. The policy uses the 'approved client app' condition with the above JSON. What will this policy enforce?

Accepted Answer

Only allow access from Power Apps and Power Automate apps.. The JSON lists the approved client apps as Power Apps and Power Automate. The 'approved client app' condition in a conditional access policy requires that the client app used is one of the listed apps. Therefore, this policy allows access only from Power Apps and Power Automate, blocking all other apps. Option C is correct. Option A is incorrect because the policy does not block Power Apps and Power Automate; it allows them. Option B is incorrect because the policy does not require compliance; it only checks the app identity. Option D is incorrect because the policy does not require multi-factor authentication; it only checks the app.

Answer

Block access from Power Apps and Power Automate.

Answer

Allow access from any app but require compliance.

Answer

Require multi-factor authentication for Power Apps and Power Automate.

Question 4

Refer to the exhibit. The JSON shows the definition of a Power Apps canvas app. Based on the exhibit, which data source is the app connected to?

Accepted Answer

SharePoint list. The JSON clearly shows the data source type as 'SharePointList'. Option A is correct. Option B is wrong because Dataverse is not listed. Option C is wrong because SQL Server is not listed. Option D is wrong because Excel is not listed.

Answer

Microsoft Dataverse

Answer

SQL Server

Answer

Excel Online

Question 5

Refer to the exhibit. The JSON defines a business process flow for expense reports in a model-driven app. How many stages must be completed before the process is considered complete?

Accepted Answer

Both stages (Submit and Approval).. Both stages 'Submit' and 'Approval' must be completed because the process flow includes them. Option C is correct. Option A is wrong because the process has two stages. Option B is wrong because the Approval stage also needs completion. Option D is wrong because the process does not have three stages.

Answer

Only the Approval stage.

Answer

All three stages (including a hidden stage).

Answer

Only the Submit stage.

Question 6

A company wants to build a custom app that allows employees to submit expense reports from their mobile devices. The app must be easy to customize and deploy without writing code. Which type of Power App should they use?

Accepted Answer

Canvas app. Canvas apps allow building custom, code-free apps that can run on mobile devices. Model-driven apps are more data-centric and require more configuration, while Power Pages is for external websites and Power Automate is for workflows.

Answer

Power Automate

Answer

Power Pages

Answer

Model-driven app

Question 7

A business analyst creates a canvas app connected to a SharePoint list. Users report that the app loads slowly when accessing it on their mobile phones. What is the most likely cause?

Accepted Answer

The app retrieves all columns from the SharePoint list on startup. Slow loading on mobile is often due to too many data source calls on startup. Using fewer columns reduces load time. The app size and delegation issues are less likely to be the primary cause here.

Answer

The app uses a non-delegable query

Answer

The SharePoint list has more than 500 items

Answer

The app uses too many images and controls on the first screen

Question 8

A Power Apps model-driven app includes a business process flow (BPF) for order processing. After editing the BPF, some users see the old version while others see the new version. What is the most likely reason?

Accepted Answer

Some users have not refreshed their app session. BPF changes are cached and refreshed when users reload the app. Admin vs. user views can differ due to security roles, but the inconsistency is due to caching.

Answer

Users have different security roles that show different BPF stages

Answer

The BPF was published to only a subset of users

Answer

The BPF was not activated after editing

Question 9

An organization needs to create a custom app that displays data from Dynamics 365 Sales and allows users to update records. The app should automatically generate a responsive UI based on the data model. Which type of app should they build?

Accepted Answer

Model-driven app. A model-driven app is the correct choice because it automatically generates a responsive UI based on the underlying data model (e.g., Dynamics 365 Sales entities like Account, Contact, Opportunity). It provides built-in forms, views, and business process flows that allow users to view and update records without manual UI design, aligning with the requirement for automatic UI generation and data update capabilities.

Answer

Canvas app

Answer

Power Automate

Answer

Power Pages

Question 10

A company uses a canvas app to collect customer feedback. The app stores data in Microsoft Dataverse. Users report that some submissions are not saved when the app loses internet connection. How should the app be modified to prevent data loss?

Accepted Answer

Enable offline capability in the app settings. Enabling offline capability with a local cache allows data to be saved locally and synced when online. Reducing controls or increasing data limit won't solve offline loss.

Answer

Use a SharePoint list instead of Dataverse

Answer

Reduce the number of controls on the form

Answer

Increase the data row limit in Dataverse

Question 11

A Power Apps developer creates a canvas app that uses the 'Power Apps for Makers' license. The app is shared with 50 users who have 'Microsoft 365 E3' licenses. When users try to run the app, they get a licensing error. What is the most likely cause?

Accepted Answer

The app is a premium app that requires a Power Apps per user license. Canvas apps require Power Apps per user or per app licenses for users without Power Apps for Makers. Microsoft 365 E3 includes only limited Power Apps rights for basic use, not premium custom apps.

Answer

The app was published to a different environment

Answer

The app uses Microsoft Dataverse, which is not included in E3

Answer

The app uses AI Builder, which is not included in E3

Question 12

A user wants to create a simple app to track personal expenses using an Excel file stored in OneDrive. Which Power Apps approach should they use?

Accepted Answer

Create a canvas app from the Excel file. A canvas app can be created directly from an Excel file stored in OneDrive using the Power Apps 'Start from data' option. This generates a three-screen app (browse, detail, edit) that connects to the Excel table via the OneDrive for Business connector, making it ideal for simple personal expense tracking without requiring Dataverse or custom development.

Answer

Use Power Pages to display the Excel file

Answer

Create a model-driven app using Dataverse

Answer

Use Power Automate to create a mobile app

Question 13

A model-driven app shows a custom form with fields from two related tables: Order and Customer. The form is set to display the Customer fields as a subgrid. Users want to see Customer details inline without navigating away. What should the app maker do?

Accepted Answer

Use a quick view form for the Customer table. Quick view forms allow displaying related entity fields inline. Subgrids show lists, not detail fields. Custom pages are for canvas experiences. Form sections don't add inline detail from other tables.

Answer

Add a new form section for Customer fields

Answer

Create a custom page with a canvas control

Answer

Add a subgrid for the Customer table

Question 14

A canvas app uses a SharePoint list as its data source. The list contains over 5000 items. Users can only see the first 500 items in the app. What is the most likely solution?

Accepted Answer

Modify the query to use a delegable filter. Power Apps has a default delegation limit of 500 items for non-delegable queries. Using a delegable query (e.g., Filter with column that supports delegation) solves this. Changing to gallery doesn't help; increasing list size limit is not possible; switching to Dataverse avoids the issue but is a bigger change.

Answer

Change the gallery to display items in a data table

Answer

Migrate the data to Microsoft Dataverse

Answer

Increase the SharePoint list view threshold

Question 15

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

Accepted Answer

Business process flows. Model-driven apps include business process flows and dashboards natively, while canvas apps require custom implementation. Custom connectors and offline capability are available in both.

Answer

Custom connectors

Answer

Responsive design

Answer

Offline capability
