PL-900 Practice Test 30 — 15 Questions

Question 1

An app maker creates a canvas app that uses a Dataverse table with 100,000 records. The app includes a gallery that displays all records. Users experience long load times. What should the app maker do to improve performance without changing the data source?

Accepted Answer

Use delegable functions in the gallery's Items property. Option C is correct because using delegable filters ensures that only relevant data is retrieved, reducing load. Option A is wrong because removing filters could increase data load. Option B is wrong because increasing the data row limit in Dataverse may not help; the issue is delegation. Option D is wrong because using a different data source is not allowed.

Answer

Switch to a SharePoint list as the data source

Answer

Increase the data row limit in Dataverse settings

Answer

Remove all filters from the gallery

Question 2

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. Option B is correct because using a gallery to show orders and linking to a detail screen is a common pattern. Option A is wrong because a single form is not efficient for browsing. Option C is wrong because a data table is less interactive than a gallery. Option D is wrong because exporting to Excel is not an app.

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 3

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.. A Power Automate flow triggered on status change (D) is the correct way to send email automatically. A is a manual action. B does not trigger automatically. C requires user interaction.

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 6

A business analyst wants to create a Power App without writing code. They need to build a mobile-friendly form for inventory tracking. Which approach should they use?

Accepted Answer

Create a canvas app from a template or blank, using drag-and-drop controls. Option C is correct because canvas apps allow drag-and-drop design without code. Option A is wrong because model-driven apps require some configuration but are not as flexible for custom forms. Option B is wrong because portals are for external users. Option D is wrong because SharePoint customizations are limited and not mobile-friendly by default.

Answer

Answer

Create a Power Apps portal

Answer

Customize a SharePoint list form

Question 7

Which TWO Power Apps features allow you to integrate AI capabilities into your app? (Choose two.)

Accepted Answer

Copilot integration. Options A and D are correct because AI Builder allows you to add AI models to Power Apps, and Copilot integration allows you to embed AI-powered copilots. Options B and C are incorrect because Power Automate is a separate product and Power Virtual Agents is a separate product for chatbots. Option E is incorrect because the Common Data Model is a data schema, not an AI feature.

Answer

Power Virtual Agents

Answer

Power Automate

Answer

Common Data Model

Question 8

Refer to the exhibit. You are reviewing the app definition XML for a model-driven app. Based on the exhibit, which tables are included in the app?

Accepted Answer

Account, contact, opportunity. Option B is correct because the <component> elements list account, contact, and opportunity. Option A is wrong because dashboard is a component type, not a table. Option C is wrong because it includes an extra table 'lead'. Option D is wrong because it omits opportunity.

Answer

Account, contact, opportunity, lead

Answer

Account, contact

Answer

Account, contact, opportunity, salesDashboard

Question 9

A Power Apps canvas app uses a SharePoint list as its data source. Users report that the app is slow to load when the list contains over 10,000 items. What is the best approach to improve performance?

Accepted Answer

Use delegation-compatible functions and filters in the app.. Delegation allows queries to be processed on the data source side, reducing data transferred. Option C is correct. Option A is wrong because it doesn't address the root cause. Option B is wrong because limiting fields might not help if delegation is not used. Option D is wrong because using a different data source may not be feasible.

Answer

Increase the data row limit in the app settings.

Answer

Switch to a Microsoft Dataverse data source.

Answer

Reduce the number of columns in the SharePoint list.

Question 10

A company wants to build an app that allows employees to submit expense reports. The app must include approval workflow. Which Power Platform component should be used to define the approval process?

Accepted Answer

Power Automate. Power Automate is the tool for creating approval workflows. Option D is correct. Option A is wrong because Power Apps is for building the app interface, not the workflow. Option B is wrong because Power BI is for data visualisation. Option C is wrong because Power Virtual Agents is for chatbots.

Answer

Power Virtual Agents

Answer

Power Apps

Answer

Power BI

Question 11

You have a canvas app that uses a Microsoft Dataverse table. Users need to see only their own records. What is the most efficient method to implement this security?

Accepted Answer

Use the Filter function with User().Email or User().FullName.. Using the Filter function with the User() function retrieves only relevant records. Option A is correct. Option B is wrong because security roles apply at the data source level but may require additional configuration. Option C is wrong because it removes the ability to see own records. Option D is wrong because storing User ID in the app is not secure.

Answer

Remove the datasource permissions and let the app handle all security.

Answer

Set up Dataverse security roles and assign them to users.

Answer

Store the user ID in a global variable and use it in queries.

Question 12

Your organisation has a Power Apps canvas app that uses a custom connector to call an external API. The API key is stored in a global variable. What is the security concern with this approach?

Accepted Answer

The API key can be exposed to end users in the app code.. Storing secrets in global variables is insecure because they can be accessed in the app code and potentially exposed. Option B is correct. Option A is wrong because the issue is about secret exposure, not custom connector use. Option C is wrong because the API may still work. Option D is wrong because the concern is not about global variables being slow.

Answer

The custom connector cannot be used with Power Apps.

Answer

Global variables cannot store API keys because they are read-only.

Answer

The API key will expire quickly.

Question 13

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 14

Which THREE components are part of a canvas app's formula language?

Accepted Answer

Functions. Canvas app formulas use functions, operators, and controls. Dataverse tables are data sources, not formula components. Power Automate flows are separate.

Answer

Dataverse tables

Answer

Power Automate flows

Question 15

A model-driven app for inventory management uses a custom entity 'Warehouse'. The app maker added a subgrid showing 'Warehouse Items' related to the selected warehouse. However, the subgrid does not show any data even though there are items linked. What is the most likely cause?

Accepted Answer

The relationship between Warehouse and Warehouse Items is not configured correctly or is missing.. The subgrid must have a relationship defined between Warehouse and Warehouse Items; if the relationship is missing or incorrectly configured, the subgrid will not display related records. Option A is wrong because security roles affect visibility, not relationship. Option C is wrong because the subgrid does not require lookup field on the main form. Option D is wrong because subgrids can be added to forms.

Answer

The Warehouse form does not include the lookup field to Warehouse Items.

Answer

The user does not have read permissions on the Warehouse Items entity.

Answer

The subgrid component is not supported on the main form.
