PL-900 Demonstrate the capabilities of Power Pages — Timed 10 Questions

Question 1

A company wants to create a public-facing website for citizens to submit permit applications and track their status. The site must allow anonymous access and integrate with Dataverse for backend storage. Which Power Platform component should the company use?

Accepted Answer

Power Pages. Power Pages is designed for external-facing websites with anonymous access capabilities and Dataverse integration. Power Apps is for internal apps, Power Automate for workflows, and Power BI for analytics.

Answer

Power Automate

Answer

Power BI

Answer

Power Apps

Question 2

A Power Pages site needs to display data from a Dataverse table only to authenticated users with a specific role. The data includes sensitive personal information. What is the best approach to secure the data?

Accepted Answer

Set the page permission to 'Authenticated Users' and use a web role to grant access.. Power Pages uses web roles to control access to pages and data. Column-level permissions are not available, and custom code is insecure. Disabling anonymous access alone doesn't restrict by role.

Answer

Write a custom JavaScript to check user roles and hide the data.

Answer

Disable anonymous access and allow all authenticated users.

Answer

Configure column-level security in Dataverse to restrict the columns.

Question 3

A Power Pages site is experiencing slow load times because it loads all records from a large Dataverse table. The site uses a list component to display data. What is the most effective way to improve performance without custom code?

Accepted Answer

Add a FetchXML filter to the list to load only the necessary records.. Power Pages list components can use FetchXML to filter data server-side, reducing data transfer. Paging in the browser still loads all data if not filtered. OData filters are less efficient. Caching is not a standard feature.

Answer

Use an OData query parameter to limit the number of records.

Answer

Enable client-side caching in the site settings.

Answer

Implement server-side paging by setting the 'Page Size' property in the list configuration.

Question 4

An organization needs to allow external vendors to log in to a Power Pages site using their existing Microsoft Entra ID accounts. What authentication provider should be configured?

Accepted Answer

Microsoft Entra ID provider. Microsoft Entra ID (formerly Azure AD) is the correct provider for organizational accounts. The local provider is for internal users. OAuth 2.0 is a protocol, not a provider name. 'Microsoft Account' is for personal accounts.

Answer

OAuth 2.0 provider

Answer

Local authentication provider

Answer

Microsoft Account provider

Question 5

A Power Pages site uses a custom form to capture customer feedback. The form should send an email notification to the support team when a new submission is made. What is the recommended way to achieve this?

Accepted Answer

Create a Power Automate flow triggered when a new row is added to the Dataverse table.. Power Automate can be triggered from a Dataverse table event when a new record is created, and send email. Using a custom workflow or Business Rule is less flexible. JavaScript is not reliable for server-side actions.

Answer

Configure a Business Rule on the form to send an email.

Answer

Use a custom JavaScript to call an email API.

Answer

Set up a classic workflow in Dataverse.

Question 6

A Power Pages site has multiple content pages and uses a custom theme. The marketing team wants to change the site's header logo and primary color. What is the most efficient method to apply these changes?

Accepted Answer

Use Power Pages Studio to update the site's theme and logo.. Power Pages Studio provides a no-code interface to modify site styling, including logo and theme colors. Editing CSS in Visual Studio Code is complex and may break the site. Using the Portal Management app is possible but less intuitive. Modifying the Liquid template is unnecessary.

Answer

Navigate to the Portal Management app and update the site settings.

Answer

Edit the site's CSS file directly in Visual Studio Code.

Answer

Modify the Liquid template that renders the header.

Question 7

A company wants to allow customers to view their order history on a Power Pages site. Customers must log in to see their own orders only. Which feature should be used to enforce data security?

Accepted Answer

Configure entity permissions for the Orders table and assign to a web role.. Entity permissions in Power Pages allow you to define granular access rights (Create, Read, Update, Delete) for specific Dataverse tables. By configuring entity permissions for the Orders table and assigning them to a web role that is associated with the authenticated user, you ensure that customers can only see their own orders based on the relationship between the Contact record and the Orders table. This is the correct approach because it enforces row-level security tied to the authenticated user's identity.

Answer

Enable column-level security on the Orders table.

Answer

Use a custom authentication provider to filter data.

Answer

Set page permissions to require authentication.

Question 8

A Power Pages site has a form that submits data to Dataverse. Users report that the form is slow to load because it contains many lookup fields. What is the best practice to improve form load performance?

Accepted Answer

Reduce the number of lookup fields on the form.. Option A is correct because reducing the number of lookup fields directly decreases the number of separate database queries and network round-trips required to load the form. Each lookup field in a Power Pages form triggers an individual request to Dataverse to retrieve the related record's display name and metadata, so fewer lookups means fewer requests and faster load times.

Answer

Disable the cascading lookup feature.

Answer

Enable client-side caching for lookups.

Answer

Add FetchXML filters to each lookup to limit results.

Question 9

A Power Pages site must display a chart showing monthly sales data from Dataverse. The chart should update automatically when new data is added. What is the recommended approach?

Accepted Answer

Embed a Power BI report that connects to Dataverse.. Power Pages can embed Power BI reports, which can refresh automatically. Using a list with a chart is limited to basic charts and may not auto-refresh. Custom JavaScript is complex and unreliable. Excel export is static.

Answer

Write custom JavaScript using the Chart.js library.

Answer

Use a list component with a chart visualization.

Answer

Export data to Excel and display as an image.

Question 10

Which TWO of the following are capabilities of Power Pages?

Accepted Answer

Integrate with Dataverse for data storage. Power Pages allows creation of external websites and supports integration with Dataverse, but it does not create mobile apps or run complex machine learning models directly.

Answer

Run complex machine learning models

Answer

Automate business processes using workflows

Answer

Build custom mobile apps for iOS and Android
