PL-900 Demonstrate the capabilities of Power Apps Practice Test 6 — 15 Questions

Question 1

A company wants to create a mobile app for field service technicians to log work orders. The app must use a SharePoint list as the data source and include offline capability. Which type of Power App should they build?

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

Accepted Answer

Canvas app. A canvas app allows custom layout and offline support via Power Apps mobile. Model-driven apps (C) are primarily for data management and require online connectivity. Power Pages (A) is for external websites. Power Automate (B) is for workflow automation.

Answer

Power Pages site

Answer

Power Automate flow

Answer

Model-driven app

Question 2

A Power Apps developer created a canvas app that uses a SQL Server data source. Users report that the app is slow when navigating between screens. Which design change should the developer make to improve performance?

Accepted Answer

Apply delegation-compatible filters on galleries to reduce data loaded from the server.. To improve performance in a canvas app with a SQL Server data source, the most effective design change is to apply delegation-compatible filters on galleries (option D). Delegation allows the server to process the filtering, reducing the amount of data transferred to the app and speeding up screen navigation. Option A is incorrect because replacing SQL Server with SharePoint does not inherently improve delegation; both support delegation, but the root cause is unfiltered data loads. Option B is wrong because moving logic to App.OnStart preloads data only once, not per screen, and doesn't address data volume during navigation. Option C is incorrect because preloading with a Timer control adds complexity and does not reduce the data transferred; delegation is the proper solution.

Answer

Replace the SQL data source with a SharePoint list to increase delegation limits.

Answer

Move all data loading logic from OnVisible to the App.OnStart property.

Answer

Add a Timer control to preload data for the next screen.

Question 3

A model-driven app uses a custom table 'Service Request' with a status field. The business requires that when a status changes to 'Resolved', the app automatically sends an email to the requester. Which approach should be used?

Accepted Answer

Create a Power Automate flow with a trigger 'When a record is updated' and condition on status change.. The correct approach is to create a Power Automate flow with a trigger 'When a record is updated' and a condition on the status change to 'Resolved'. This automates the email sending when the status is updated. Option A (PCF control) requires custom development and does not automatically trigger on status change. Option C (manual button) requires user interaction and does not trigger automatically. Option D (business rule) cannot send emails directly; business rules only modify fields or show messages.

Answer

Use a Power Apps component framework (PCF) control to trigger an email.

Answer

Add a button on the form that runs a Power Automate flow on demand.

Answer

Create a business rule that sends an email when the status is updated.

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 (option A) is the correct solution because it enables external-facing websites that can be accessed by anonymous users without requiring a Microsoft account or license. Canvas apps and model-driven apps require authenticated users with appropriate licenses, and Power Automate is an automation service, not a portal for external submissions.

Answer

Canvas app shared with everyone

Answer

Model-driven app with anonymous access

Answer

Power Automate portal

Question 5

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.. The Switch function in the gallery's Fill property directly maps each priority choice value to a color without requiring additional tables, flows, or nested conditions. Option A adds an unnecessary lookup table, option B involves an external flow which is overkill for simple color mapping, and option D uses multiple If conditions which is less efficient and harder to maintain than a Switch function.

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 6

A model-driven app has a subgrid showing related opportunities. Users want to be able to edit opportunity fields directly in the subgrid without opening the record. Which feature should be enabled?

Accepted Answer

Change the subgrid type from 'Standard' to 'Editable'.. Editable subgrid (C) allows inline editing. A is for charts. B is for custom views. D is for read-only subgrids.

Answer

Enable the 'Chart' option on the subgrid properties.

Answer

Set the subgrid's 'Default view' to a custom view.

Answer

Set the subgrid's 'View Selector' to show multiple views.

Question 7

A company has a canvas app that uses Microsoft Dataverse. The app is shared with many users, and some users report that they cannot see any data. What is the most likely cause?

Accepted Answer

Users do not have appropriate security roles in Dataverse to read the data.. Permissions in Dataverse (A) control data access. B, C, D are less likely because the app is shared and appears functional.

Answer

The app uses a premium connector that requires a license.

Answer

The app is not published to the environment.

Answer

The app is configured to run only on mobile devices.

Question 8

A Power Apps developer needs to store an image uploaded by a user in a canvas app. The app uses Microsoft Dataverse. Which column type should be used for the image?

Accepted Answer

Image column. Image column (B) in Dataverse is designed to store images. A is for text. C is for files. D is binary but not directly accessible.

Answer

Text column

Answer

File column

Answer

Binary column

Question 9

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.. The most likely cause is that the business rule is configured to run only when the form loads, not when a field is changed. In model-driven apps, business rules can be set to trigger 'on form load' or 'on every change'. If the rule is set to 'on form load', it will execute only when the form initially opens and will not re-fire when the 'Request Type' field is changed later. This matches option C. Option A is incorrect because scope 'All Forms' includes custom forms. Option B is incorrect because the condition type ('contains' vs 'equals') would not prevent the rule from firing; it would affect which records meet the condition. Option D is incorrect because a deactivated rule would never fire, not just when changing a field.

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 10

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 11

Which TWO actions can be performed using Power Apps? (Choose two.)

Accepted Answer

Create a mobile app to capture customer feedback.. Power Apps allows users to create custom apps with minimal code. Option D (create a mobile app to capture customer feedback) is a core use case for Power Apps, enabling rapid development of data-driven mobile applications. Option E (build a custom portal for external users to submit support tickets) can be achieved using Power Apps portals, which extend app capabilities to external audiences. Option A describes Power BI (dashboards and visualizations). Option B is Power Virtual Agents (chatbots). Option C is Power Automate (workflow automation). Therefore, the correct choices are D and E.

Answer

Build interactive dashboards with visualizations.

Answer

Create a chatbot to answer common questions.

Answer

Automate a business process to send email notifications.

Question 12

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

Accepted Answer

Microsoft Dataverse. Microsoft Dataverse and SharePoint are standard connectors that can be used without a premium license. Salesforce requires a premium connector. Excel Online (Business) is also a standard connector, but the correct answers for this question are Dataverse and SharePoint. SQL Server requires a premium connector.

Answer

Salesforce

Answer

Excel Online (Business)

Answer

SQL Server

Question 13

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. (Canvas app) 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 14

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 15

A business analyst wants to build an app quickly using a pre-built template. Which Power Apps capability should they use?

Accepted Answer

Use a Power Apps template from the template gallery. Power Apps offers templates for common scenarios. Canvas apps from blank require more effort. Model-driven apps are not template-based. Power Automate is for workflows.

Answer

Create a Model-driven app from a Dataverse table

Answer

Use Power Automate to generate the app

Answer

Create a Canvas app from blank
