PL-900 Practice Test 24 — 15 Questions

Question 1

Refer to the exhibit. You are deploying a Power Pages site using an ARM template. After deployment, you find that the portal uses local authentication, but you need it to use Microsoft Entra ID. What is the most likely reason the authentication provider is not set correctly?

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

Accepted Answer

The 'authentication' property should be 'identityProviders' with the correct configuration.. The exhibit shows an ARM template with the 'authentication' property set to 'Local'. However, the correct property for configuring identity providers in ARM templates for Power Pages is 'identityProviders', not 'authentication'. Additionally, the API version '2022-03-01-preview' may not support the full configuration. The most likely reason is that the template uses an incorrect property name. Option A is incorrect because local authentication is not the only option. Option C is incorrect because the portal URL does not affect authentication. Option D is incorrect because the location is not relevant.

Answer

The portal URL must be changed to use Microsoft Entra ID.

Answer

The portal location must be in a region that supports Microsoft Entra ID.

Answer

The portal only supports local authentication when deployed via ARM.

Question 2

A company has a Power BI dashboard that displays real-time data from Azure Stream Analytics. Which connection type should they use?

Accepted Answer

Push dataset. Push datasets are designed for real-time streaming scenarios where data is pushed into Power BI via APIs, such as from Azure Stream Analytics. Unlike Import or DirectQuery, Push datasets support automatic refresh of streaming data without requiring a scheduled refresh, making them ideal for real-time dashboards.

Answer

Import

Answer

DirectQuery

Answer

Composite model

Question 3

A financial analyst creates a Power BI report to compare quarterly revenue across years. The data has a 'Date' column and a 'Revenue' column. The analyst wants to display year-over-year growth for each quarter. Which visual and configuration would best achieve this?

Accepted Answer

Matrix visual with years as columns, quarters as rows, and a measure for YoY growth. A Matrix visual allows you to place years as columns and quarters as rows, then define a DAX measure for year-over-year (YoY) growth (e.g., (Current Year Revenue - Previous Year Revenue) / Previous Year Revenue). This directly compares each quarter’s revenue across years in a structured, tabular format, which is the most effective way to display YoY growth for each quarter.

Answer

Line chart with date hierarchy and revenue, adding year-over-year trend line

Answer

Stacked bar chart with quarters on axis and revenue as values, using year as legend

Answer

Scatter plot with revenue on both axes and date as detail

Question 4

A company wants to automate the process of sending a welcome email to new employees after their HR record is created in Dataverse. Which component should be used?

Accepted Answer

Power Automate. Power Automate is the correct choice because it is designed to create automated workflows that trigger on events in Dataverse, such as the creation of a new HR record. It can then perform actions like sending a welcome email via connectors (e.g., Office 365 Outlook) without manual intervention.

Answer

Power Apps

Answer

Power Virtual Agents

Answer

Power BI

Question 5

Refer to the exhibit. A Power Automate flow fails with the error shown. What is the most likely cause?

Accepted Answer

The SharePoint connection used in the flow does not have write permissions. The error message indicates a permission issue when the flow attempts to write to the SharePoint list. Since the flow trigger and HTTP request URL are validated at design time and the SharePoint site is accessible (the flow runs but fails), the most likely cause is that the SharePoint connection used in the flow lacks write permissions on the target list or library.

Answer

The flow trigger is misconfigured

Answer

The SharePoint site is offline

Answer

The HTTP request URL is malformed

Question 6

A company wants to create a public-facing website for customers to submit support tickets, view their ticket history, and update their profile information. Non-authenticated users should only see a welcome page and login option. Which Power Pages feature should be used to control access to pages based on authentication status?

Accepted Answer

Page permissions. Page permissions in Power Pages control access to pages based on user roles and authentication status. Web roles define groups, and page permissions are assigned to those roles. Option A is incorrect because page templates define layout, not access. Option B is incorrect because content snippets are reusable text/HTML, not access control. Option D is incorrect because list forms are for data entry, not page access.

Answer

Content snippets

Answer

List forms

Answer

Page templates

Question 7

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. In the exhibit, the Home page is published and therefore visible to anonymous users, while the Contact page is in Draft status, which is not visible to anonymous users. Options A and B are incorrect (Both pages and Neither page, respectively). Option D is incorrect because the Contact page is not published.

Answer

Both pages

Answer

Neither page

Answer

Only the Contact page

Question 8

An organization uses Power Automate to process invoices from email attachments. Some invoices are processed incorrectly because the flow fails to parse PDFs with non-standard layouts. What should the administrator do to improve accuracy?

Accepted Answer

Use AI Builder to create a custom document processing model.. AI Builder provides prebuilt and custom document processing models that use optical character recognition (OCR) and machine learning to extract data from PDFs with non-standard layouts. This directly addresses the root cause—parsing failures due to layout variability—by training the model on sample invoices to handle diverse formats, unlike static parsing logic.

Answer

Increase the flow run frequency to every minute.

Answer

Add a condition to route non-parsed invoices for manual approval.

Answer

Change the trigger to a manual button in Power Apps.

Question 9

A manufacturing company uses Power Apps to manage inventory tracking. The current app is a canvas app connected to a SharePoint list. The operations team needs to add a new feature that allows warehouse staff to scan barcodes using a mobile device camera to look up product details. Additionally, the app must work offline in areas with no internet connectivity and sync data when connectivity is restored. The app should also incorporate a Copilot assistant to help staff quickly find product information using natural language queries. The IT department requires that the app be deployed to all warehouse staff without requiring manual installation. Which approach should you take to meet all requirements?

Accepted Answer

Add the Barcode scanner control, configure the app for offline use with sync, integrate Copilot using the AI Builder 'Ask a question' component, and deploy the app via Power Apps mobile app with a managed solution and installation policy.. It combines the Barcode scanner control for camera-based scanning, offline capabilities via Power Apps mobile app with offline sync, Copilot in Power Apps for natural language queries, and automatic deployment using a managed solution and Power Apps mobile app installation policy. Option A fails to address offline and Copilot requirements. Option B uses Power Fx formula, which is not a native barcode scanning method. Option C uses Power Automate flows, which are not suitable for real-time offline scanning.

Answer

Add a Text input control for manual barcode entry, use Power Automate flows to fetch product details, enable offline by storing data locally in collections, and deploy by sending a deep link.

Answer

Use a Power Fx formula with the Camera control to decode barcodes, enable offline data in SharePoint lists, add a Copilot chat box, and deploy via Microsoft Intune as a required app.

Answer

Add the Barcode scanner control to the canvas app, enable offline mode in app settings, integrate Copilot using the Copilot control, and deploy the app by sharing it via email link.

Question 10

A company uses Power BI dashboards to monitor real-time production metrics. The dashboards use DirectQuery to a SQL Server database. Users report that the dashboards are slow during peak hours. What is the most effective first step to improve performance?

Accepted Answer

Optimize the SQL queries used in the dataset. Optimizing the SQL queries used in the dataset directly addresses the root cause of slow DirectQuery performance: inefficient queries sent to the SQL Server. DirectQuery translates Power BI visuals into SQL queries executed in real time on the source database, so poorly written or unindexed queries create bottlenecks during peak loads. Improving query efficiency (e.g., adding indexes, reducing joins, filtering early) reduces server load and response time without requiring architectural changes.

Answer

Create aggregations in the dataset

Answer

Increase the Power BI Premium capacity

Answer

Switch the dataset to Import mode

Question 11

Refer to the exhibit. A Power Pages site configuration snippet shows authentication settings. What does this configuration achieve?

Accepted Answer

Users sign in with their Microsoft Entra ID accounts.. The configuration sets Microsoft Entra ID as the authentication provider, meaning users will sign in using their Entra ID credentials. It does not enable local authentication or anonymous access, and it does not require multi-factor authentication.

Answer

Multi-factor authentication is enforced.

Answer

Anonymous access is allowed for all users.

Answer

Users authenticate using local credentials stored in Dataverse.

Question 12

You are designing a canvas app for field service technicians. The app must capture photos of equipment and store them with the service record. Which control and data source combination is most suitable?

Accepted Answer

Camera control with Microsoft Dataverse. The Camera control captures photos directly within the canvas app, and Microsoft Dataverse can store these images using file or image columns, providing a robust data source for field service records. Option B is incorrect because the Add media control only supports media capture in Power Apps Mobile and Excel Online is not capable of storing binary image data effectively. Option C is incorrect because the Attachments control is designed for SharePoint lists but does not capture photos in-app; it only manages file attachments. Option D is incorrect because the Image control displays images but does not capture them, making it unsuitable for this requirement.

Answer

Add media control with Excel Online

Answer

Attachments control with SharePoint list

Answer

Image control with SharePoint list

Question 13

You are the Power Platform administrator for a large enterprise with multiple departments. The HR department uses a Power Apps canvas app to manage employee onboarding. The app is connected to Dataverse and includes a flow that sends a welcome email via Power Automate. Recently, the IT security team mandated that all Power Platform solutions must use Microsoft Entra ID for authentication and that sensitive data (e.g., social security numbers) must be encrypted at rest. The HR app currently uses Dataverse's default encryption. Additionally, the HR team wants to extend the app to external contractors who do not have Microsoft Entra ID accounts. They need to be able to submit their personal information through a secure web form. You need to design a solution that meets security requirements and allows external access. What should you do?

Accepted Answer

Enable customer-managed encryption key (CMEK) for Dataverse, and create a Power Pages site with Microsoft Entra External ID authentication for external contractors.. It addresses both security requirements: customer-managed encryption key (CMEK) for Dataverse ensures sensitive data like social security numbers is encrypted at rest with a key controlled by the enterprise, meeting the IT security mandate. Additionally, creating a Power Pages site with Microsoft Entra External ID authentication allows external contractors without Microsoft Entra ID accounts to authenticate via social or email-based identities, enabling secure submission of personal information through a web form while maintaining compliance.

Answer

Create a SharePoint list for external contractors to submit data, and use Power Automate to send emails.

Answer

Use Power Apps portals with Microsoft Entra ID B2B collaboration for external contractors, and leave encryption as default.

Answer

Implement a Power Automate flow to collect data via Microsoft Forms, and store results in Dataverse with default encryption.

Question 14

You review a failed flow run with the log shown. The flow is supposed to send an email when a SharePoint item is created. What is the most likely issue?

Accepted Answer

The email connector is not properly configured or the SMTP server is down. The flow log shows a failure in the 'Send an email' action, not the trigger. Since the trigger (SharePoint 'When an item is created') successfully initiated the flow, the issue lies with the email connector. The most likely cause is that the email connector (e.g., Office 365 Outlook, SMTP) is misconfigured—such as incorrect SMTP server, port, authentication, or the SMTP server being unreachable—preventing the email from being sent.

Answer

The SharePoint trigger did not fire

Answer

The scope 'SendNotification' failed due to a missing variable

Answer

The SharePoint list permissions are incorrect

Question 15

A company has a legacy system that exposes a REST API. They want to build a Power App that displays data from this API and allows users to update records. Which connector should they use?

Accepted Answer

HTTP with Azure AD connector. The HTTP with Azure AD connector can call any REST API and supports authentication, making it suitable for integrating with a legacy system that exposes a REST API. Option B is wrong because the Office 365 Users connector is designed for retrieving user profiles from Microsoft 365, not for calling custom REST APIs. Option C is wrong because the SQL Server connector is used to connect to SQL databases, not REST APIs. Option D is wrong because the SharePoint connector is intended for interacting with SharePoint lists and documents, not for consuming REST APIs.

Answer

Office 365 Users connector

Answer

SQL Server connector

Answer

SharePoint connector
