PL-900 Practice Test 29 — 15 Questions

Question 1

A model-driven app has a business rule that sets the 'Priority' field to 'High' when the 'Request Type' is 'Urgent'. However, the rule does not fire when the request type is changed from the form. What is the most likely cause?

Accepted Answer

The business rule only triggers when the form loads, not on field changes.. Business rules (D) run on the form, not on background updates. A, B, C are not relevant because business rules are not affected by code or order.

Answer

The business rule is set to scope 'All Forms' but the form is custom.

Answer

The condition uses 'contains' instead of 'equals'.

Answer

The business rule is deactivated in the solution.

Question 2

A company wants to use Power Apps to create a mobile app for field technicians. The app must work offline and sync data when connectivity is restored. Which feature should they use?

Accepted Answer

Offline capability in Dataverse (mobile offline sync). Option B is correct because Dataverse supports offline mobile experiences. Option A is not a Power Apps feature. Option C is for debugging. Option D is for performance optimization.

Answer

Power Apps portals

Answer

Power Apps component framework

Answer

Monitor tool in Power Apps

Question 3

Your model-driven app uses a custom entity 'Project' with a 1:N relationship to 'Task'. You need to add a subgrid on the Project form that shows related tasks, but only tasks assigned to the current user. How should you achieve this?

Accepted Answer

Create a system view on the Task entity that filters by 'Owner equals Current User' and select it in the subgrid properties. Option C is correct because you can create a view on the Task entity that filters by the 'Assigned To' field equals the current user, then use that view in the subgrid. Option A is wrong because security roles control access but not subgrid filtering. Option B is wrong because business rules cannot filter subgrids. Option D is wrong because workflows run in the background.

Answer

Create a workflow that updates a field on the Project form to filter the subgrid

Answer

Add a business rule on the Project form to filter the subgrid

Answer

Configure the subgrid to use the default view and assign security roles to filter tasks

Question 4

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 5

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

Question 6

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 7

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. Option A is correct because if the filter uses Dropdown.Selected.Value, when nothing is selected the value is blank, causing the filter to fail. Option B is wrong because the dropdown is not required to be cleared; the issue is the filter. Option C is wrong because performance is not the issue. Option D is wrong because the data source is likely fine.

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 8

Refer to the exhibit. A Power App uses the Patch function to create a new record in the Orders table. The code runs without error, but no record appears in the Orders table. What is the most likely issue?

Accepted Answer

The user does not have write permissions to the Orders table. Option B is correct because Patch returns the created record, but if the result is not assigned to a variable or used, the record may not be saved if there is a missing required field or permission issue. However, the most common cause is that the Patch function is missing the record to patch (second argument should be a record, but Defaults(Orders) is correct for creation). The issue could be that the table does not have a primary key or the user lacks permissions. Option B is plausible.

Answer

The Patch function is missing the 'As' parameter

Answer

The table name 'Orders' is misspelled

Answer

The Patch function is being called from a non-delegable data source

Question 9

A company wants to build a Power App that uses AI to analyze survey responses and extract sentiment. Which Power Platform capability should they use?

Accepted Answer

AI Builder sentiment analysis model. AI Builder (C) provides pre-built models for sentiment analysis. A is for reporting. B is for automation. D is for low-code, not AI.

Answer

Power BI dashboards

Answer

Power Automate flows

Answer

Power Apps Canvas app with formulas

Question 10

A user wants to add a chart to a model-driven app to visualize sales data. Which component should they use?

Accepted Answer

Chart component from the Dataverse table. Option A is correct because model-driven apps include built-in chart visualization for Dataverse data. Option B is for Canvas apps. Option C is for custom visuals in Power BI. Option D is not a standard chart component.

Answer

Chart control from the Power Apps canvas

Answer

Excel chart imported into the app

Answer

Power BI tile embedded in the app

Question 11

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 12

Which TWO of the following are valid data sources for Power Apps?

Accepted Answer

Microsoft SharePoint. SharePoint and Dataverse are both supported data sources. Option A and Option D are correct. Option B is wrong because Excel Online requires a gateway or OneDrive. Option C is wrong because SQL Server requires a gateway or connection. Option E is wrong because JSON is a format, not a data source.

Answer

Microsoft Excel (desktop file)

Answer

SQL Server (on-premises)

Answer

JSON file

Question 13

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 14

A canvas app displays a label with the formula shown. Users report that the label shows 'Welcome, !' without a name. What is the most likely cause?

Accepted Answer

The user is not authenticated with Power Apps. The User() function returns the current user's details. If the user is not signed in or the app doesn't have permission, FullName may be blank. The formula syntax is correct, and concatenation works.

Answer

The FullName property is spelled incorrectly

Answer

The ampersand (&) operator is incorrect

Answer

The User() function is not available in canvas apps

Question 15

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

Accepted Answer

Use of formulas like If, Switch, Filter. Canvas apps allow custom formulas and mobile device features (camera, GPS). Model-driven apps do not have formula-based logic; they use business rules/processes. Option A is available in both. Option B is available in both (embedded canvas). Option D is not a feature.

Answer

Integration with Microsoft Dataverse

Answer

Ability to use AI Builder models

Answer

Embedding a canvas app in a model-driven app
