PL-900 Practice Test 26 — 15 Questions

Question 1

A company wants to build a canvas app to allow field technicians to report equipment issues from their mobile devices. The app must work offline and sync data when connectivity is restored. Which feature should the developer use?

Accepted Answer

Offline. Option B is correct because Power Apps canvas apps support offline capability using the Offline feature, which caches data on the device and syncs when connectivity returns. Option A is wrong because the Common Data Service (now Microsoft Dataverse) is a data platform but does not directly provide offline capabilities; the Offline feature sets up sync. Option C is wrong because the Power Platform admin center is for administration. Option D is wrong because Power Automate flows can be part of the solution but are not the offline feature itself.

Answer

Power Automate

Answer

Power Platform admin center

Answer

Common Data Service

Question 2

Which THREE are valid data sources for a canvas app? (Choose three.)

Accepted Answer

SharePoint list. Option A is correct because SharePoint lists are supported. Option C is correct because SQL Server is supported. Option D is correct because Excel files stored in OneDrive are supported. Option B is wrong because Azure DevOps is not a direct canvas app data source (use connectors). Option E is wrong because Power BI datasets are not data sources; you can embed reports but not use as source.

Answer

Azure DevOps work items

Answer

Power BI dataset

Question 3

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. Option C is correct because constant refreshing of large datasets can cause memory accumulation. Option A is wrong because 5 minutes is not too frequent. Option B is wrong because the timer does not cause memory leaks by itself. Option D is wrong because network latency does not degrade over time.

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 4

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 (C) is designed for external-facing websites with anonymous access. Canvas apps (A) require Power Apps licenses. Model-driven apps (B) require authenticated users. Power Automate (D) is for workflows.

Answer

Canvas app shared with everyone

Answer

Model-driven app with anonymous access

Answer

Power Automate portal

Question 5

A company wants to create a custom app to track inventory in their warehouse. The app needs to integrate with their existing SQL Server database and allow users to scan barcodes to update stock levels. Which type of Power Apps should they use?

Accepted Answer

Canvas app. Option A is correct because Canvas apps allow custom integration with SQL Server and barcode scanning via device capabilities. Model-driven apps are more for data management but not as flexible for custom scanning. Power Pages is for external websites, not scanning. Power Automate is for workflows, not app building.

Answer

Power Pages

Answer

Power Automate

Answer

Model-driven app

Question 6

Which THREE of the following are true about model-driven apps? (Choose THREE.)

Accepted Answer

They have built-in role-based security. Options A, C, and E are correct. Model-driven apps are responsive, built on Dataverse, and use role-based security. Option B is incorrect because they do not support custom formulas like Canvas apps. Option D is incorrect because they are available for web and mobile (not just web).

Answer

They require custom formulas for business logic

Answer

They can only be used on web browsers

Question 7

A company wants to build a Power App that uses AI to extract information from uploaded invoices. Which capability should they use?

Accepted Answer

AI Builder invoice processing model. Option D is correct because AI Builder provides prebuilt models for invoice processing. Option A is wrong because Power Virtual Agents is for chatbots. Option B is wrong because Copilot Studio is for custom copilots. Option C is wrong because Power Automate can incorporate AI Builder but is not the AI capability itself.

Answer

Power Automate with OCR actions

Answer

Power Virtual Agents

Answer

Copilot Studio

Question 8

You are troubleshooting a canvas app that loads slowly. The app uses over 50 data sources and many formulas. Which action is most likely to improve performance?

Accepted Answer

Use delegable queries to filter data at the source. Option C is correct because delegable queries reduce the amount of data transferred by processing on the server side. Option A is wrong because removing data sources might break functionality. Option B is wrong because increasing the data row limit can worsen performance. Option D is wrong because disabling error checking does not affect performance.

Answer

Increase the data row limit for each data source

Answer

Disable the formula-level error checking

Answer

Remove unused data sources from the app

Question 9

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 10

Refer to the exhibit. You are configuring a conditional access policy in Microsoft Entra ID to restrict access to Microsoft 365 services. The policy uses the 'approved client app' condition with the above JSON. What will this policy enforce?

Accepted Answer

Only allow access from Power Apps and Power Automate apps.. The JSON lists approved apps: Power Apps and Power Automate. The policy will block access from other apps. Option B is correct. Option A is wrong because it does not require MFA. Option C is wrong because there is no block for Power Apps. Option D is wrong because it targets all apps.

Answer

Block access from Power Apps and Power Automate.

Answer

Allow access from any app but require compliance.

Answer

Require multi-factor authentication for Power Apps and Power Automate.

Question 11

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. Option B is correct because security roles in model-driven apps define permissions, including delete rights. Option A is wrong because business rules define logic, not permissions. Option C is wrong because the app's properties do not include security settings. Option D is wrong because the SharePoint connector is for integration, not security.

Answer

Business rules

Answer

SharePoint connector

Answer

App properties

Question 12

Which TWO capabilities does Power Apps provide? (Choose two.)

Accepted Answer

Implementing business process flows. Option B is correct because canvas apps allow custom layouts. Option D is correct because model-driven apps provide business process flows. Option A is wrong because Power Apps does not create Power BI dashboards natively. Option C is wrong because Power Automate handles scheduled automations. Option E is wrong because AI Builder is a separate add-on, not a core capability of Power Apps.

Answer

Creating Power BI dashboards

Answer

Scheduling automated workflows

Answer

Training custom AI models

Question 13

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. Option A is correct because sharing directly with users or groups is a standard method. Option C is correct because sharing via a security group is also possible. Option B is wrong because the app must be published first. Option D is wrong because Power Apps does not generate a public URL for sharing. Option E is wrong because exporting and importing is for transferring between environments, not sharing.

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 14

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.. Using the Switch function in the gallery control (A) allows direct conditional formatting without additional datasources. B is overkill for simple mapping. C requires a separate lookup table. D is less efficient than A.

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 15

A user reports that their Canvas app freezes when loading data from a SharePoint list that has grown to over 5,000 items. What is the most appropriate solution?

Accepted Answer

Add filters to the data source to delegate the query and reduce the data loaded. Option B is correct because the SharePoint delegation limit is 5,000 items. Using delegation with filters ensures only relevant data is retrieved. Option A increases delegation limit but still loads all items. Option C is unnecessary for performance. Option D is for on-premises data, not SharePoint.

Answer

Use a SQL Server database instead of SharePoint

Answer

Move the data to a Microsoft Dataverse table

Answer

Increase the data row limit in Power Apps settings to 10,000
