PL-900 Practice Test 49 — 15 Questions

Question 1

Refer to the exhibit. A Power Pages site is configured with the given authentication settings. When a user clicks 'Sign In', they are redirected to Microsoft Entra ID, but after successful login, they are redirected back to the site and see an error. What is the most likely cause?

Accepted Answer

The redirectUrl is not registered in the Microsoft Entra ID app.. The redirectUrl must be registered as a reply URL in the Microsoft Entra ID app registration. If it is missing, the login fails.

Answer

The clientId is invalid.

Answer

The tenantId is incorrect.

Answer

The site requires HTTPS but is using HTTP.

Question 2

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 3

Refer to the exhibit. A Power Pages web role configuration snippet is shown. What access does this web role grant to the 'incident' entity?

Accepted Answer

Read all incidents, write incidents related to the user, and create new incidents.. The configuration grants read, write, and create privileges with different scopes. Read and create are Global (all records), write is Deep (records owned by user's business unit). Scope 'Contact' means records related to the user's contact record.

Answer

No access because the scope is set to Contact.

Answer

Only read incidents related to the user's contact.

Answer

Read, write, and create all incident records globally.

Question 4

A Power Pages site uses a custom Liquid template to display a list of events. The template uses {% assign events = entities.event | top: 10 %} but the page shows no results even though there are events in Dataverse. What is the most likely cause?

Accepted Answer

The user's web role lacks read permission on the Event table. Option C is correct because table permissions must allow read access for the user's web role. Option A is wrong because 'top' is a valid filter and syntax is correct. Option B is wrong because page caching would not affect Liquid execution. Option D is wrong because Liquid syntax errors would cause an error message, not empty results.

Answer

The 'top' filter is not valid in Liquid

Answer

Page caching is preventing fresh data

Answer

The Liquid syntax is incorrect

Question 5

A Power Pages site needs to display a chart showing sales data from a Dataverse table. The chart must update automatically when data changes. Which component should you use?

Accepted Answer

Add a PCF (Power Apps component framework) control. Option C is correct because PCF controls can be embedded in Power Pages to display dynamic charts. Option A is wrong because Power BI embedded requires a separate license and setup. Option B is wrong because charts are not native to Power Pages without custom development. Option D is wrong because Excel Online is not integrated.

Answer

Embed a Power BI report

Answer

Use an Excel Online iframe

Answer

Use a chart web template from the portal

Question 6

Refer to the exhibit. A Power Pages site has two pages. Which page(s) are visible to anonymous users?

Accepted Answer

Only the Home page. Option A is correct because only published pages are visible. Option B is wrong because Draft pages are not visible. Option C is wrong because Home is published. Option D is wrong because only Home is published.

Answer

Both pages

Answer

Neither page

Answer

Only the Contact page

Question 7

Which TWO of the following are valid authentication providers for Power Pages? (Choose two.)

Accepted Answer

Local authentication. Power Pages supports multiple identity providers. Microsoft Entra ID (Option A) is commonly used for internal users. Local authentication (Option C) allows users to sign up with an email/password. Option B (Windows authentication) is not supported in Power Pages. Option D (Microsoft Account) is not directly supported as a standalone provider; it can be used via Azure AD B2C. Option E (LDAP) is not supported.

Answer

LDAP

Answer

Microsoft Account

Answer

Windows authentication

Question 8

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

Question 9

You are troubleshooting a Power Pages site where authenticated users in the 'Partner' web role cannot see any records from a Dataverse table, even though the table permission is set to 'Read' with 'Contact' scope. The site uses a custom page that retrieves data via a Liquid template. What is the most likely cause?

Accepted Answer

The table permission is not enabled for the 'Partner' web role.. Liquid templates respect table permissions only if the permission is enabled, otherwise they may bypass security.

Answer

The 'Partner' web role does not inherit the 'Authenticated Users' role permissions.

Answer

The Liquid template is using a direct Web API call that bypasses table permissions.

Answer

The contact record for the user does not have the correct 'Owner' value.

Question 10

Which TWO statements about Power Pages security are true?

Accepted Answer

Page permissions can restrict access to specific pages based on web roles.. Options A and D are correct. Page permissions (A) control access to individual pages, and table permissions (D) control access to Dataverse data. Option B is wrong because authentication providers are configured in Power Pages admin, not Dataverse. Option C is wrong because web roles can be associated with multiple users. Option E is wrong because IP restrictions are not a built-in feature; they are handled at the Azure level.

Answer

Authentication providers are configured in Dataverse.

Answer

IP restrictions can be set directly in Power Pages.

Answer

Web roles can only be assigned to one user at a time.

Question 11

Which TWO components are required to build a Power Pages site?

Accepted Answer

A Dataverse environment. Options A and B are correct. A Dataverse environment is required to store data, and a Power Pages license is required to create the site. Option C is wrong because Azure AD B2C is optional. Option D is wrong because Power Automate is optional. Option E is wrong because a custom domain is optional.

Answer

Custom domain

Answer

Azure AD B2C tenant

Answer

Power Automate license

Question 12

A Power Pages site uses a custom Liquid template to display a chart using Chart.js. The chart data is fetched from a Dataverse table using a web API call from JavaScript. The page loads but the chart fails to render. You suspect a cross-origin issue. What is the most likely cause and solution?

Accepted Answer

Upload the Chart.js library as a web file in the portal and reference it locally.. Power Pages sites impose a Content Security Policy (CSP) that restricts the sources from which scripts and data can be loaded. The external Chart.js library may be loaded from a CDN that is not allowed by the CSP. The solution is to upload the Chart.js library to the portal's web files and reference it locally. Option A is incorrect because disabling CSP is not recommended. Option B is incorrect because the web API call to Dataverse is same-origin. Option D is incorrect because cookies are not typically the issue.

Answer

Disable Content Security Policy in the portal settings.

Answer

Configure the web API call to use credentials: 'include'.

Answer

Use a different JavaScript library that doesn't require external resources.

Question 13

Refer to the exhibit. A Power Pages developer is creating a custom page template using Liquid. The template includes a reference to a CSS file hosted on the portal's CDN. However, the CSS does not apply when the page is viewed. What is the most likely cause?

Accepted Answer

The CSS file URL is incorrect; it should be a relative path to the web file.. The exhibit shows a Liquid template that includes a static link to a CSS file. However, in Power Pages, the correct way to reference portal web files is to use the web file's path relative to the portal root, not the full CDN URL. The CDN URL might be blocked by Content Security Policy (CSP) or the file might not be accessible via that direct URL. The most likely cause is that the CSS file URL is incorrect or not accessible. Option B is incorrect because Liquid syntax is correct. Option C is incorrect because the HTML structure is fine. Option D is incorrect because the header include is not related to CSS not applying.

Answer

The page template is missing a DOCTYPE declaration.

Answer

The header web template is overriding the CSS.

Answer

The Liquid syntax for including the header is wrong.

Question 14

Which TWO of the following are capabilities of Power Pages?

Accepted Answer

Create data-driven websites using Dataverse. Option A is correct because Power Pages allows external users to access sites. Option C is correct because Power Pages uses Dataverse as the primary data source. Option B is wrong because Power Pages is not a low-code platform for building mobile apps; that is Power Apps. Option D is wrong because Power Pages does not include an integrated SQL editor. Option E is wrong because Power Pages does not include advanced analytics; that is Power BI.

Answer

Generate advanced analytics reports and dashboards

Answer

Build canvas mobile apps with offline capabilities

Answer

Run SQL queries directly on the site

Question 15

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
