PL-900 Demonstrate the capabilities of Power Apps Practice Test 12 — 15 Questions

Question 1

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. Security roles in model-driven apps define permissions, including the ability to delete records. Option B is wrong because business rules define business logic and form behavior, not security permissions. Option C is wrong because the SharePoint connector is used for integration with SharePoint, not for security. Option D is wrong because app properties control settings like appearance and ownership, not security permissions.

Answer

Business rules

Answer

SharePoint connector

Answer

App properties

Question 2

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. Canvas apps allow flexible formulas, such as DateDiff, to automatically calculate the number of days between two dates, making them ideal for forms requiring custom calculations. Option A is wrong because Power Apps portal is designed for external-facing websites, not internal employee forms. Option C is wrong because Power Automate is an automation tool, not a form-building app. Option D is wrong because model-driven apps use standardized forms and custom calculations are less straightforward compared to canvas apps.

Answer

Power Apps portal

Answer

Power Automate

Answer

Model-driven app

Question 3

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. Canvas apps can be embedded directly into a Teams channel using the Power Apps app in Teams. Option B is incorrect because AI Builder is not an app type; it is a feature for adding AI models to apps. Option C is incorrect because model-driven apps are designed for data-centric business applications and, while they can be added to Teams as a tab, they are not typically embedded directly into a Teams channel like a canvas app. Option D is incorrect because Power Virtual Agents are chatbots, not the type of app needed for embedding into Teams.

Answer

AI Builder

Answer

Model-driven app

Answer

Power Virtual Agents

Question 4

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

Answer

Common Data Service

Question 5

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. The Power Apps maker portal (make.powerapps.com) is the central environment for customizing model-driven apps, including editing forms. Within the maker portal, you can navigate to the specific app, open the form designer, and add, remove, or rearrange fields. This is the only option that provides the necessary design-time tools for form customization.

Answer

From the app itself by selecting Edit

Answer

Power Automate

Answer

SharePoint list settings

Question 6

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. To capture offline images and signatures in a Power App, you need a canvas app with offline capability and the Camera and Signature controls. The app can store data locally and sync to Dataverse when connectivity is restored. This combination directly supports the required offline capture of text, images, and signatures.

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 7

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. A canvas app is ideal for building a simple expense report app without writing code. It allows the maker to drag and drop controls, connect to data sources, and design a custom user interface. Canvas apps are well-suited for task-specific apps like expense submission and approval.

Answer

Power Pages

Answer

Copilot Studio

Answer

Model-driven app

Question 8

A company uses a Power App to track inventory. The app displays a gallery of items filtered by a dropdown. When the user selects 'Electronics', the gallery shows all electronics items. However, after the user clears the dropdown, the gallery remains empty. What is the most likely reason?

Accepted Answer

The gallery's Items property uses a filter that references Dropdown.Selected.Value, and when the dropdown is cleared, the filter returns blank. When the dropdown is cleared, Dropdown.Selected.Value becomes blank. The gallery's Items property uses a filter that references this value, so the filter returns blank (no items), causing the gallery to be empty. Option A is incorrect because AllowEmptySelection set to false would prevent clearing, not cause emptiness after clearing. Option B is incorrect because the data source does not require a refresh; the issue is the filter logic. Option D is incorrect because OnStart is not involved in the clearing behavior.

Answer

The dropdown's AllowEmptySelection property is set to false

Answer

The data source requires a refresh after clearing selection

Answer

The app's OnStart property is clearing the data source

Question 9

A Power App uses a Patch function to update a Dataverse table. The app runs into delegation warnings for large datasets. Which approach best resolves delegation warnings while maintaining functionality?

Accepted Answer

Use delegable functions such as Filter and LookUp to retrieve only necessary records before performing updates. Using delegable functions like Filter and LookUp allows the app to process only the necessary subset of records from Dataverse, avoiding delegation warnings by keeping data operations within the server's capacity. Option A is wrong because increasing the data row limit only changes the number of records fetched, but does not resolve delegation warnings; it may even exacerbate performance issues. Option B is wrong because switching to SharePoint does not inherently fix delegation problems—SharePoint has different delegation limits and may still trigger warnings. Option C is wrong because avoiding delegable functions would likely make delegation warnings worse, as non-delegable functions force the app to load all data locally.

Answer

Increase the data row limit in the app settings

Answer

Switch the data source to SharePoint for better delegation support

Answer

Avoid using delegable functions to reduce complexity

Question 10

A manager wants to create a Power App that shows a list of customer orders with the ability to drill into each order's details. Which approach is most efficient?

Accepted Answer

Use a gallery to list orders and navigate to a detail screen on selection. The gallery control is the standard Power Apps pattern for displaying a list of records from a data source, and its OnSelect property can navigate to a detail screen while passing the selected record's context. This approach is efficient because it uses a single reusable detail screen that dynamically displays the selected order, avoiding duplication. It also leverages built-in delegation and performance optimizations for large datasets when configured correctly.

Answer

Use a data table connected directly to the data source

Answer

Use a single form with navigation buttons to move between orders

Answer

Export the data to Excel and use Power Apps to display the Excel file

Question 11

A model-driven app uses a custom table 'Service Request' with a status field. The business requires that when a status changes to 'Resolved', the app automatically sends an email to the requester. Which approach should be used?

Accepted Answer

Create a Power Automate flow with a trigger 'When a record is updated' and condition on status change.. To automatically send an email when a record's status changes to 'Resolved', the best approach is to create a Power Automate flow with a trigger 'When a record is updated' and a condition that checks if the status field changed to 'Resolved'. This provides a no-code, automated solution that runs in the background.

Answer

Use a Power Apps component framework (PCF) control to trigger an email.

Answer

Add a button on the form that runs a Power Automate flow on demand.

Answer

Create a business rule that sends an email when the status is updated.

Question 12

A company wants to build an app that allows external vendors to submit invoices through a web portal. The app must be accessible without signing in with a Microsoft account. Which Power Platform solution should they use?

Accepted Answer

Power Pages site with anonymous access enabled. Power Pages (option A) is the correct solution because it enables external-facing websites that can be accessed by anonymous users without requiring a Microsoft account or license. Canvas apps and model-driven apps require authenticated users with appropriate licenses, and Power Automate is an automation service, not a portal for external submissions.

Answer

Canvas app shared with everyone

Answer

Model-driven app with anonymous access

Answer

Power Automate portal

Question 13

A Power Apps app uses a Dataverse table with a choice column 'Priority' (Low, Medium, High, Critical). The app must display the priority as a color-coded badge in a gallery. Which method is most efficient?

Accepted Answer

Use the Switch function in the gallery's Fill property to map each choice value to a color.. The Switch function evaluates a single expression against multiple possible values and returns a corresponding result, making it the cleanest and most efficient way to map four choice values to four colors in one formula. It is more readable and performs better than nested If statements because it evaluates the expression once. This is the idiomatic Power Apps pattern for choice-to-color mapping.

Answer

Add a second table with colors and use LookUp in the gallery.

Answer

Create a Power Automate flow to update a color field on the record.

Answer

Use an If function with multiple conditions to set the Fill property.

Question 14

A model-driven app has a subgrid showing related opportunities. Users want to be able to edit opportunity fields directly in the subgrid without opening the record. Which feature should be enabled?

Accepted Answer

Change the subgrid type from 'Standard' to 'Editable'.. To allow users to edit opportunity fields directly within a subgrid, the subgrid must be configured as an editable grid. This feature enables inline editing of records without opening them. Changing the subgrid type from 'Standard' to 'Editable' is the correct configuration.

Answer

Enable the 'Chart' option on the subgrid properties.

Answer

Set the subgrid's 'Default view' to a custom view.

Answer

Set the subgrid's 'View Selector' to show multiple views.

Question 15

A company has a canvas app that uses Microsoft Dataverse. The app is shared with many users, and some users report that they cannot see any data. What is the most likely cause?

Accepted Answer

Users do not have appropriate security roles in Dataverse to read the data.. In Microsoft Dataverse, access to data is governed by security roles assigned to users. If users can open the canvas app but see no data, the most likely cause is that their Dataverse security roles do not grant read privileges on the tables the app queries. Sharing the app itself does not automatically grant Dataverse data permissions.

Answer

The app uses a premium connector that requires a license.

Answer

The app is not published to the environment.

Answer

The app is configured to run only on mobile devices.
