PL-900 Demonstrate the capabilities of Power Apps Practice Test 5 — 15 Questions

Question 1

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?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Use a canvas app with offline capability and the Camera and Signature controls, syncing to Dataverse when online. Canvas apps in Power Apps support offline capability, and the Camera and Signature controls can capture images and signatures while offline, syncing to Dataverse when connectivity is restored. Option A is incorrect because a SharePoint list with Power Apps integration does not support offline capture of images and signatures; SharePoint requires connectivity for such data. Option B is incorrect because although the Offline template and Dataverse provide offline capabilities, the Offline template is designed for basic data types and does not inherently support image and signature capture; you would need to use Camera and Signature controls as in option C. Option D is incorrect because model-driven apps with Dataverse offline sync have limitations on which controls can be used offline, and typically they do not support the Camera and Signature controls in the same way a canvas app does.

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 2

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. Canvas apps (Option A) are the correct choice because they allow business analysts to build custom apps without writing code, using drag-and-drop interfaces. They are ideal for simple forms like expense reports. Option B (Power Pages) is for creating external-facing websites, not apps. Option C (Copilot Studio) is for building conversational AI chatbots. Option D (Model-driven apps) requires a Dataverse database and schema, which adds complexity and is not necessary for a simple expense report app.

Answer

Power Pages

Answer

Copilot Studio

Answer

Model-driven app

Question 3

A Power App connected to Dataverse uses a column of type 'Choice' with two options: 'Active' and 'Inactive'. The app needs to display only active records by default. Which filter expression should be used in the app's OnStart property?

Accepted Answer

Filter(Accounts, Status = 'Active'). Uses the correct syntax: Filter(Accounts, Status = 'Active') with no quotes around the column name and single quotes around the choice value. Option D incorrectly uses double quotes around both the column name and value, which will cause an error. Options B and C also have wrong quotation usage. Therefore, only Option A is correct.

Answer

Filter(Accounts, "Status" = 'Active')

Answer

Filter(Accounts, Status = "Active")

Answer

Filter(Accounts, "Status" = "Active")

Question 4

A user reports that a Power App button does nothing when clicked. The button's OnSelect property contains: Navigate(Screen2). What is the most likely cause?

Accepted Answer

Screen2 does not exist in the app. If Screen2 does not exist, the Navigate function fails silently, causing the button to appear to do nothing. Option A is incorrect because the formula syntax is valid and parentheses are properly used. Option B is incorrect because navigation permissions are not enforced within the same app; any user can navigate between screens. Option C is incorrect because the app does not need to be published for the button to work in the editor or when running the app.

Answer

The formula is missing parentheses

Answer

The user lacks permission to navigate to Screen2

Answer

The app is not published

Question 5

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 6

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 7

A Power App is used by a global team. The app displays dates in US format (MM/DD/YYYY), but users in Europe expect DD/MM/YYYY. What is the best way to handle this?

Accepted Answer

Do nothing; Power Apps automatically formats dates based on the user's browser locale. Power Apps automatically formats dates based on the user's browser locale, respecting regional preferences without custom code. Option A is wrong because hardcoding a format ignores the user's locale and requires manual detection. Option C is wrong because the Language function returns locale information, but Power Apps already handles locale automatically; manually setting the format is unnecessary and can override the automatic behavior. Option D is wrong because using a text input for dates loses the validation and user experience benefits of a date picker and still requires locale-specific formatting.

Answer

Hardcode the date format based on the user's region in the app

Answer

Use the Language function to set the date format manually

Answer

Use a text input for dates instead of a date picker

Question 8

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. Using a gallery to list orders and navigating to a detail screen on selection is the most efficient pattern for browsing and drilling into details. Option A is incorrect because a data table directly connected to the data source does not provide an easy way to drill into each order's details without additional configuration. Option C is incorrect because a single form with navigation buttons is less efficient for browsing a list and requires manual navigation. Option D is incorrect because exporting to Excel defeats the purpose of a real-time app and is not efficient.

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 9

A Power App uses a Timer control to refresh data every 5 minutes. The app experiences performance degradation after running for several hours. What is the most likely cause?

Accepted Answer

The data source is not delegating queries, causing the app to load all data each time. If the data source does not support delegation, Power Apps loads all rows into memory each time the Timer control triggers a refresh. Over several hours, the accumulation of data in memory causes performance degradation. Option A is incorrect: while a Timer control could contribute to memory usage if not properly disposed, it does not inherently have a memory leak. Option B is incorrect: a 5-minute interval is not excessively short for typical data refresh scenarios. Option C is incorrect: CDNs are used for static content delivery, not for resolving memory buildup from non-delegated queries.

Answer

The Timer control has an internal memory leak

Answer

The timer interval is too short, causing excessive network calls

Answer

The app is not using a CDN for static resources

Question 10

Which TWO are valid ways to share a canvas app with other users in your organization? (Select two.)

Accepted Answer

Add users to a security group that has been granted access to the app. Adding users to a security group that has been granted access to the app is a valid way to share. Option C is correct because sharing the app directly with individual users or Microsoft Entra ID groups is the primary sharing method. Option A is wrong because the app must be published before sharing a link. Option D is wrong because Power Apps does not generate public URLs for sharing. Option E is wrong because exporting as a .msapp file is for transferring between environments, not for sharing with users.

Answer

Send a direct link to the app via email before publishing

Answer

Generate a public URL that anyone in the organization can use

Answer

Export the app as a .msapp file and email it to users

Question 11

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

Accepted Answer

Dataverse tables. Dataverse tables provide the data foundation for model-driven apps. Option C is correct because views define which records to display and in what format. Option D is correct because forms define how data is presented for viewing or editing. Option B is incorrect because Power Automate flows are automations, not core components of a model-driven app. Option E is incorrect because canvas app screens belong to canvas apps, not model-driven apps.

Answer

Power Automate flows

Answer

Canvas app screens

Question 12

Which TWO data sources can be used directly in a canvas app without a premium connector? (Select two.)

Accepted Answer

SharePoint list. SharePoint is a standard connector in Power Apps canvas apps. Option E is correct because Excel files stored in OneDrive for Business can be used through the standard OneDrive for Business connector. Option B is incorrect because SQL Server requires a premium connector. Option C is incorrect because Dataverse requires a premium license. Option D is incorrect because Salesforce requires a premium connector.

Answer

SQL Server database

Answer

Dataverse

Answer

Salesforce

Question 13

Refer to the exhibit. You are deploying a Power Apps environment using an ARM template. The template deploys a Production environment with Dataverse and the D365_FieldService template. After deployment, you need to ensure that users can create model-driven apps based on the Field Service tables. What additional step is required?

Accepted Answer

Assign appropriate Dynamics 365 licenses to users and install the Field Service app in the environment. After deploying the environment with Dataverse and the Field Service template via ARM template, users need appropriate Dynamics 365 licenses (which include rights to use Field Service) and the Field Service app must be installed in the environment (typically done through the Power Platform admin center or license assignment). This step is required to make the Field Service tables available for model-driven app creation. Option B is incorrect because the ARM template already includes Dataverse, so no manual database addition is needed. Option C is incorrect because the deployed environment already contains the necessary template. Option D is incorrect because model-driven apps do not require Power Automate flows for basic functionality.

Answer

Add a Dataverse database manually after deployment

Answer

Create a new environment with a different template

Answer

Create a Power Automate flow to sync Field Service data

Question 14

Refer to the exhibit. A canvas app has a gallery (Gallery1) with the Items property shown. The app also has a text input (TextSearchBox1) for searching accounts. Users report that when they type a search term, the gallery does not update until they click a button. What is the most likely cause?

Accepted Answer

The gallery's Items property is set to a static value instead of using TextSearchBox1.Text. The gallery's Items property is set to a static value instead of using TextSearchBox1.Text. In canvas apps, the Items property of a gallery must dynamically reference the text input's Text property to update as the user types. If it's set to a static collection or a value that doesn't change, the gallery won't reflect search input until it's manually refreshed (e.g., by a button). Option D directly addresses this issue.

Answer

The data source is not delegable, causing the filter to fail

Answer

The text input's OnChange event is not set to refresh the gallery

Answer

The gallery's DelayOutput property on the text input is set to true

Question 15

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. If the user does not have write permissions to the Orders table, the Patch function may execute without throwing an error but the record will not be created. Options A and B would typically cause an error, not silent failure. Option D (non-delegable data source) does not prevent record creation. Therefore, the most likely cause is insufficient permissions.

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
