PL-900 Demonstrate the capabilities of Power Apps — 10 Questions

Question 1

Which THREE components are part of a model-driven app? (Choose three.)

Accepted Answer

Forms. Model-driven apps are composed of components such as forms (for data entry), views (for data display), and sitemap (for navigation). Screens are not a component of model-driven apps; they are used in canvas apps. Triggers are not relevant to model-driven apps; they are used in Power Automate. Therefore, the correct three components are Forms, Views, and Sitemap.

Answer

Screens

Answer

Triggers

Question 2

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. Power Apps uses delegation to process queries efficiently. SharePoint has a default delegation limit of 5,000 items; when a list exceeds this, the app may freeze. By adding filters that can be delegated (e.g., using operators like '=' or '>' on indexed columns), the query is executed on the server, returning only matching items. Option A is not the most appropriate because switching to SQL Server involves unnecessary migration and does not inherently solve the delegation issue; SQL Server also has limits and requires delegatable queries. Option C (Dataverse) also has delegation limits, so migrating is not a direct fix. Option D (increasing the data row limit) does not address delegation; it still loads all items into the app, causing performance issues.

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

Question 3

You are designing a model-driven app for a sales team. The app must show related opportunities on an account form using a subgrid. The subgrid should only display open opportunities. Which configuration should you apply?

Accepted Answer

Add a subgrid and select a view that filters for status equals 'Open'. A subgrid in a model-driven app can be filtered by a view that filters for open opportunities. Option B is wrong because business rules cannot filter subgrids. Option C is wrong because calculated fields modify data, not filter subgrids. Option D is wrong because workflows run in the background and don't filter subgrids.

Answer

Use a business rule to hide closed opportunities

Answer

Set a calculated field to mark opportunities as open

Answer

Create a workflow to remove closed opportunities from the subgrid

Question 4

An organization needs a Power App that allows employees to submit expense reports by filling out a form and attaching receipts. Which type of app should you create and why?

Accepted Answer

Canvas app, because it provides flexible form design and supports file attachments. Canvas apps are best for custom form-based interfaces with file uploads. Option B is wrong because model-driven apps use standard Dataverse forms, which are less flexible for custom form design and file attachments. Option C is wrong because AI Builder is an add-on capability, not a standalone app type; it can process receipts but cannot create the form itself. Option D is wrong because Power Apps portals are designed for external users, not internal employees submitting expenses.

Answer

Model-driven app, because it uses standard Dataverse forms

Answer

AI Builder app, because it can process receipts automatically

Answer

Power Apps portal, because it allows external users to submit expenses

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'. The policy is a JSON business rule that sets the 'description' field to 'High-value account' when the revenue exceeds $1,000,000. Since the saved record has revenue of $2,000,000, the condition is met, so the description is updated. Therefore, Option A is correct. Option B is incorrect because the policy only updates an attribute and does not block save. Option C is incorrect because it does not change the revenue. Option D is incorrect because it does not create a task; it only sets a field.

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

A company uses a model-driven app to manage customer cases. The app needs to ensure that when a case is resolved, the resolution time (in hours) is automatically calculated and stored in a custom field. Which feature should be used?

Accepted Answer

A real-time workflow (cloud flow) triggered when a case is resolved.. (calculated field) is incorrect because calculated fields are computed only when the record is created or updated via the form, and they cannot recalculate based on subsequent status changes. Option B (real-time workflow/cloud flow) is correct because a Power Automate cloud flow can be triggered immediately when a case is updated and, if the status is 'Resolved', calculate the resolution time and update the custom field. Option C (business rule) is incorrect because business rules run on the client side and cannot perform calculations that persist to the database or reference other record fields dynamically. Option D (scheduled flow) is incorrect because it runs on a timer, not in response to the status change, resulting in delays and potential inaccuracies.

Answer

A calculated field that computes the difference between created and resolved dates.

Answer

A business rule that sets the resolution time field when the status changes.

Answer

A scheduled Power Automate flow that runs every hour and updates resolved cases.

Question 7

An organization plans to build a Power App that will be used by external partners. The app must allow partners to log in with their own credentials (Azure AD B2B). Which feature should be configured?

Accepted Answer

Set up Azure AD B2B guest user access. Azure AD B2B enables external users to use their own identities for Power Apps. Option A is wrong because SharePoint external sharing settings are for sharing SharePoint content, not for authenticating users in a Power App. Option B is wrong because anonymous access would not require partners to log in with their own credentials. Option D is wrong because Azure AD B2C is designed for customer-facing identity management, not B2B partner scenarios.

Answer

Use SharePoint external sharing settings

Answer

Enable anonymous access in Power Apps

Answer

Configure Azure AD B2C for the app

Question 8

Which THREE actions can be performed using Power Apps AI Builder?

Accepted Answer

Form processing. AI Builder in Power Apps includes several prebuilt models. Option A (Form Processing) correctly extracts key-value pairs from documents. Option B (Text Classification) categorizes text into predefined classes. Option C (Sentiment Analysis) detects positive, negative, or neutral sentiment in text. Option D (Object Detection) is not a prebuilt AI Builder model; it requires custom training or Azure Cognitive Services. Option E (Predictive Forecasting) is not available in AI Builder. Therefore, the three correct actions are A, B, and C.

Answer

Object detection in images

Answer

Predictive forecasting

Question 9

Which TWO of the following are valid data sources for a canvas app?

Accepted Answer

SharePoint list. Options B and D are correct. SharePoint lists and SQL Server are common data sources for canvas apps. Option A is wrong because Power Pages is a website builder, not a data source. Option C is wrong because Power Virtual Agents is a chatbot builder and not a data source. Option E is wrong because Power BI is a visualization tool, not a data source.

Answer

Power Pages form

Answer

Power Virtual Agents topic

Answer

Power BI dataset

Question 10

You need to share a canvas app with all users in a specific Microsoft Entra ID group. The app connects to a SharePoint list. Which step is required to ensure users can access the app and data?

Accepted Answer

Share the app with the group and ensure the group has access to the SharePoint list. Sharing a canvas app requires both app-level sharing (via Power Apps) and ensuring the group has permissions to the underlying data source (SharePoint list). Option A is incorrect because adding users as co-owners gives them edit access to the app, but they still need data access; co-ownership is not required for usage. Option B is incorrect because a Power Automate flow is not necessary; app permissions and data source permissions are the only requirements. Option D is incorrect because granting Can Use permission only allows users to run the app, but they cannot access the SharePoint list data unless the group also has permissions to the list.

Answer

Add users as co-owners of the app

Answer

Create a Power Automate flow to grant access

Answer

Share the app with the group and grant Can Use permission
