PL-900 Demonstrate the capabilities of Power Apps Practice Test 7 — 15 Questions

Question 1

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

Create a model-driven app using Dataverse

Answer

Create a Power Apps portal

Answer

Customize a SharePoint list form

Question 2

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 3

Which THREE components are required to build a model-driven app in Power Apps? (Choose three.)

Accepted Answer

Dataverse tables. Dataverse tables are the core data storage and management layer in model-driven apps. They provide the structured schema, relationships, and business logic (such as calculated columns and rollups) that model-driven apps rely on for data operations. Without Dataverse tables, there is no data source to bind forms, views, or the sitemap to, making them a mandatory component.

Answer

Canvas controls

Answer

Power Automate flows

Question 4

Which TWO data sources can be used directly in a canvas app without a gateway? (Choose two.)

Accepted Answer

Microsoft Dataverse. Options A and C are correct because SharePoint and Microsoft Dataverse are cloud-based data sources that can be accessed directly without a gateway. Options B, D, and E are incorrect because SQL Server on-premises, Oracle on-premises, and SAP on-premises require an on-premises data gateway.

Answer

SQL Server on-premises

Answer

Oracle database on-premises

Answer

SAP on-premises

Question 5

Refer to the exhibit. You create a policy in Power Apps using the above JSON. The policy is applied on the account entity. What will happen when an account record with revenue of $2,000,000 is saved?

Accepted Answer

The description field will be updated to 'High-value account'. Option B is correct because the policy checks if revenue > 1,000,000; if true, it sets the description field to 'High-value account'. Option A is wrong because the policy does not block save. Option C is wrong because the policy only sets the description, not revenue. Option D is wrong because the action is to set an attribute, not to create a task.

Answer

The save operation will be blocked

Answer

A task will be created for the account owner

Answer

The revenue field will be updated to 1,000,000

Question 6

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 7

Refer to the exhibit. You deploy this ARM template to create a Power Apps environment. What will be the SKU of the created environment?

Accepted Answer

Production. Option A is correct because the property 'environmentSku' is set to 'Production'. Options B, C, and D are incorrect because they do not match the value in the template.

Answer

Sandbox

Answer

Developer

Answer

Trial

Question 8

A company wants to build a mobile app for field service technicians to view and update work orders. The app must work offline and sync when connectivity is available. Which Power Apps type should they use?

Accepted Answer

Canvas app. Canvas apps allow offline capability with explicit data sync configuration, while model-driven apps require online connectivity. Option A is correct. Option B is wrong because model-driven apps are primarily online. Option C is wrong because Power Pages are for external web portals. Option D is wrong because Power Automate is for automation, not app building.

Answer

Model-driven app

Answer

Power Automate

Answer

Power Pages

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

You are designing a Power Apps model-driven app for a sales team. The app must enforce that a discount field cannot exceed 50% of the total price. Where should you implement this validation?

Accepted Answer

Create a business rule on the table.. Business rules in model-driven apps provide real-time validation on forms. Option B is correct. Option A is wrong because the formula bar is for canvas apps. Option C is wrong because Power Automate is for backend automation, not instant form validation. Option D is wrong because JavaScript can be used but is not the recommended low-code approach.

Answer

In the canvas app formula bar.

Answer

Use a Power Automate flow triggered on record creation.

Answer

Write JavaScript in the form customisation.

Question 11

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 12

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 13

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 14

A manager wants to create an app without writing any code. Which Power Apps type should they use?

Accepted Answer

Canvas app from a template. Power Apps Studio with templates or from data allows no-code app creation. Option A is correct. Option B is wrong because model-driven apps require some configuration but still no code, but the question implies ease of use. Option C is wrong because Power Automate is for workflows. Option D is wrong because Power BI is for analytics.

Answer

Power BI

Answer

Model-driven app

Answer

Power Automate

Question 15

You have a model-driven app that includes a custom table. You need to add a field that calculates a value based on other fields (e.g., total price = quantity * unit price). Which type of field should you create?

Accepted Answer

Calculated field. Calculated fields perform calculations at the data source level. Option A is correct. Option B is wrong because rollup fields aggregate data from related records. Option C is wrong because choice fields are for dropdowns. Option D is wrong because text fields store plain text.

Answer

Text field

Answer

Choice field

Answer

Rollup field
