PL-900 Practice Test 11 — 15 Questions

Question 1

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. Security roles in model-driven apps define permissions, including the ability to delete records. Option B is wrong because business rules define business logic and form behavior, not security permissions. Option C is wrong because the SharePoint connector is used for integration with SharePoint, not for security. Option D is wrong because app properties control settings like appearance and ownership, not security permissions.

Answer

Business rules

Answer

SharePoint connector

Answer

App properties

Question 2

A non-profit organization wants to automate donation receipt emails and track donor engagement. Which Microsoft Power Platform tool should they use?

Accepted Answer

Power Automate. Power Automate is the correct tool because it enables the non-profit to create automated workflows that can trigger donation receipt emails when a new donation is recorded, and it can also update donor engagement metrics in a connected data source like Dataverse or SharePoint. This directly addresses the need for automating email notifications and tracking engagement without manual intervention.

Answer

Power Virtual Agents

Answer

Power BI

Answer

Power Apps

Question 3

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 support offline capability with explicit data sync configuration, making them suitable for field service technicians who need to work without constant connectivity. Model-driven apps require online connectivity and are not designed for offline use. Option B (Canvas app) is correct. Option A is wrong because model-driven apps are primarily online. Option C is wrong because Power Automate is for automation, not app building. Option D is wrong because Power Pages is for external web portals.

Answer

Model-driven app

Answer

Power Automate

Answer

Power Pages

Question 4

A team is designing a model-driven app for customer service. They need to ensure that only agents in the 'Premium Support' role can see a custom field named 'SLA Level'. What is the best way to implement this security requirement?

Accepted Answer

Configure field-level security in Microsoft Dataverse. Field-level security in Microsoft Dataverse allows administrators to restrict access to a specific field based on security roles. This ensures only agents in the 'Premium Support' role can see the 'SLA Level' field. Option A is incorrect because removing the field from the form would affect all users. Option B is not a standard security feature; Canvas apps are not designed for field-level permissions in model-driven apps. Option D is incorrect because a business rule can only make a field read-only, but it cannot hide the field from specific roles.

Answer

Remove the field from the form and create a separate form for Premium Support agents

Answer

Use the 'Visible' property of the field in a Canvas app embedded in the model-driven app

Answer

Create a business rule that sets the field as read-only for non-Premium roles

Question 5

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

Accepted Answer

Microsoft Dataverse. Options C and D are correct because Microsoft Dataverse and SharePoint are cloud-based data sources that can be accessed directly without a gateway. Options A, B, 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 6

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 7

An organization needs to create a form for employees to submit vacation requests. The form should automatically calculate the number of days requested based on the start and end dates. Which type of app should they build?

Accepted Answer

Canvas app. Canvas apps allow flexible formulas, such as DateDiff, to automatically calculate the number of days between two dates, making them ideal for forms requiring custom calculations. Option A is wrong because Power Apps portal is designed for external-facing websites, not internal employee forms. Option C is wrong because Power Automate is an automation tool, not a form-building app. Option D is wrong because model-driven apps use standardized forms and custom calculations are less straightforward compared to canvas apps.

Answer

Power Apps portal

Answer

Power Automate

Answer

Model-driven app

Question 8

You are troubleshooting a Power Apps issue. Using PowerShell, you run Get-AdminPowerApp and see the exhibit output. What does the EnvironmentName field indicate?

Accepted Answer

The unique identifier of the Dataverse environment hosting the app.. The EnvironmentName field in Get-AdminPowerApp output is a GUID that uniquely identifies the Dataverse environment where the app is hosted. Option A is incorrect because it is not a license key; Option C is incorrect because it is not a custom connector name; Option D is incorrect because it is not a SharePoint site name. Only Option B correctly describes the field.

Answer

The license key for Power Apps.

Answer

The name of the custom connector used by the app.

Answer

The name of the SharePoint site where the app is stored.

Question 9

A company wants to create a canvas app for field technicians to report equipment issues. The app must work offline and sync data when connectivity is restored. Which Power Apps feature should you enable?

Accepted Answer

Enable the 'Enable offline' feature in the Power Apps mobile app settings. The 'Enable offline' feature in the Power Apps mobile app settings allows canvas apps to cache data locally and sync with the server when connectivity is restored, enabling offline operation. Option A is incorrect because Power Automate flows can queue operations but do not provide native offline data caching for canvas apps. Option B is incorrect because Dataverse offline profiles are used for model-driven apps, not canvas apps. Option C is incorrect because the on-premises data gateway is for accessing on-premises data sources, not for enabling offline capabilities.

Answer

Create a Power Automate flow to queue operations

Answer

Use a Dataverse offline profile

Answer

Configure an on-premises data gateway

Question 10

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

Accepted Answer

They have built-in role-based security. Options B, C, and D are correct. Model-driven apps are built on Microsoft Dataverse, have built-in role-based security, and are responsive across devices. Option A is incorrect because model-driven apps do not require custom formulas; they use declarative logic and business rules. Option E is incorrect because model-driven apps work on both web browsers and mobile devices.

Answer

They require custom formulas for business logic

Answer

They can only be used on web browsers

Question 11

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 12

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 13

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 the amount of data transferred and improving performance. Option D is correct because delegation-compatible functions (e.g., Filter, LookUp) ensure only relevant data is retrieved. Option A is wrong because increasing the data row limit loads more data, worsening performance. Option B is wrong because switching to Dataverse might help but is not the best approach—it requires migration and may not always be feasible. Option C is wrong because reducing columns only marginally reduces data size, but without delegation, performance issues persist due to large row counts.

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 14

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 most likely cause is that the relationship between Warehouse and Warehouse Items is not configured correctly or is missing (Option C). Without a proper one-to-many relationship defined, the subgrid cannot retrieve the related records. Option A is incorrect because the lookup field belongs on the Warehouse Items entity, not on the Warehouse form; the subgrid relies on the relationship, not a lookup on the main form. Option B is incorrect because read permissions would affect all views of the entity, not just the subgrid; given that items are linked, permissions are likely sufficient. Option D is incorrect because subgrids are fully supported on main forms in model-driven apps.

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.

Question 15

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. Canvas apps allow drag-and-drop design without code, enabling the creation of mobile-friendly custom forms. Option B (model-driven app) is less flexible for custom form design and requires more configuration. Option C (Power Apps portal) is designed for external user-facing websites, not internal inventory tracking. Option D (customize SharePoint list form) is limited in mobile optimization and customization compared to a canvas app.

Answer

Create a model-driven app using Dataverse

Answer

Create a Power Apps portal

Answer

Customize a SharePoint list form
