PL-900 Practice Test 18 — 15 Questions

Question 1

A user wants to create an app that allows employees to submit expense reports from their mobile devices. The app should capture photos of receipts and store them. Which type of app is most suitable?

Accepted Answer

Canvas app. A canvas app in Power Apps provides a blank canvas where the maker designs the UI and logic from scratch, making it ideal for a mobile-friendly expense reporting app with custom photo capture and storage. Canvas apps offer full control over layout and can integrate with the camera control and connectors to store images. This matches the requirement for a tailored mobile experience.

Answer

Model-driven app

Answer

Power Apps portal

Answer

Power Automate flow

Question 2

A developer builds a canvas app that uses a custom connector to call an external API. The API requires an OAuth 2.0 client credentials flow. Which authentication type should the developer configure in the custom connector?

Accepted Answer

OAuth 2.0. OAuth 2.0 client credentials flow is a standard OAuth flow used for server-to-server authentication where no user is involved. Option B is incorrect because Windows Authentication is not OAuth-based and does not support client credentials flow. Option C is incorrect because API Key is a simple token-based authentication, not OAuth. Option D is incorrect because Basic Authentication sends credentials in plaintext and is not OAuth 2.0.

Answer

Windows Authentication

Answer

API Key

Answer

Basic Authentication

Question 3

A company uses Power Automate to automate approval workflows for purchase orders. The flow should send an approval request to the manager of the requestor. When the manager approves, the flow should update a SharePoint list and send a confirmation email. However, the flow fails with an error 'Unable to find the manager for the specified user'. What is the most likely cause?

Accepted Answer

The user profile in Microsoft Entra ID does not have a manager assigned.. The error 'Unable to find the manager for the specified user' indicates that the user's profile in Microsoft Entra ID (Azure AD) does not have a manager attribute populated. Power Automate's approval action relies on the manager relationship defined in Entra ID to route the request.

Answer

The SharePoint list column for manager is missing.

Answer

The flow trigger is set to 'When a new item is created' but the item already exists.

Answer

The SharePoint list does not have the correct permissions.

Question 4

A user wants to create a flow that runs when a specific button is clicked in a mobile app. Which type of flow should be used?

Accepted Answer

Instant flow. An instant flow is triggered manually by a user action, such as clicking a button in a mobile app, and runs on demand. Power Automate provides a mobile app where users can trigger instant flows with a button, making it the correct flow type for this requirement. Instant flows are designed for manual initiation, unlike automated or scheduled flows.

Answer

Business process flow

Answer

Scheduled flow

Answer

Automated flow

Question 5

A company uses Microsoft Power Platform to automate invoice processing. They want to integrate with their existing ERP system hosted on Azure SQL Database. Which Power Platform component is best suited for this integration?

Accepted Answer

Power Automate. Power Automate is the correct choice because it provides built-in connectors for Azure SQL Database, enabling seamless integration with the existing ERP system without custom code. It can trigger automated workflows based on invoice events, such as when a new record is created in the SQL database, and orchestrate data processing across multiple systems.

Answer

Question 6

A sales team needs to create a custom app to track leads and manage follow-ups, but they have no coding experience. Which Power Platform tool should they use?

Accepted Answer

Power Apps. Power Apps (Option D) is the correct tool because it enables users with no coding experience to build custom apps using a low-code, drag-and-drop interface. The sales team can create a lead-tracking app with forms, galleries, and data connections to Microsoft Dataverse or SharePoint without writing traditional code.

Answer

Power Pages

Answer

Power BI

Answer

Power Automate

Question 7

A sales team wants to track customer interactions and automate follow-up emails without custom development. What Microsoft Power Platform component should they use?

Accepted Answer

Power Automate. Power Automate is the correct choice because it enables the sales team to create automated workflows that trigger follow-up emails based on customer interactions, such as when a new contact is added or a meeting ends. It integrates with common data sources like Dynamics 365, SharePoint, or Outlook, and uses prebuilt connectors to send emails without any custom code.

Answer

Power BI

Answer

Power Apps

Answer

Power Virtual Agents

Question 8

A small marketing team wants to automate the process of capturing leads from their website into a Dataverse table. Currently, the website sends an email notification when a lead submits a form, and a team member manually enters the data into a Power Apps app. The team wants to eliminate manual data entry. They also want to automatically send a confirmation email to the lead and create a task in Microsoft To Do for the sales representative to follow up. You need to recommend a Power Platform solution. What should you do?

Accepted Answer

Use Power Automate to monitor the website's email inbox, parse the lead data, add it to Dataverse, send confirmation email, and create a task in Microsoft To Do.. It directly addresses the requirement to eliminate manual data entry by using Power Automate to monitor the website's email inbox (via a trigger like 'When a new email arrives'), parse the lead data from the email body or attachments, add it to a Dataverse table, send a confirmation email, and create a task in Microsoft To Do. This solution automates the entire workflow without requiring changes to the existing website form or manual intervention.

Answer

Replace the website form with a Power Apps portal form, and use Power Automate for emails and tasks.

Answer

Use Microsoft Forms to collect leads, and Power Automate to add to Dataverse and send emails.

Answer

Create a Power Apps app on the website to capture leads, and use Power Automate to send emails and create tasks.

Question 9

You are a Power Platform consultant for a large university that wants to build a public-facing Power Pages site for alumni. The site must allow alumni to register, update their profile, view upcoming events, and donate to the university. The university uses Microsoft Entra ID for staff and students, but alumni will use their personal email accounts to register. The security team requires that all data transmitted between the browser and the portal be encrypted. Additionally, the alumni relations team needs to send targeted emails to alumni based on their interests, which are captured during registration. The development team wants to use a low-code approach to integrate the donation functionality, which should process payments through a third-party payment gateway. You need to design the solution. Which of the following is the best approach?

Accepted Answer

Enable HTTPS for the site (default), store alumni profiles and interests in Dataverse, use Power Automate with a custom connector for payment processing, and use Power Automate to send targeted emails.. The best approach. Power Pages enables HTTPS by default, ensuring encrypted data transmission. Alumni can register using personal accounts via local authentication or external identity providers (like Microsoft Entra ID, but not required). Storing profiles and interests in Dataverse allows the alumni relations team to use Power Automate to send targeted emails based on interests. For payment processing, a custom connector in Power Automate can be built to call the third-party payment gateway, satisfying the low-code requirement. Option A is incorrect because using a custom web API with Liquid contradicts the low-code requirement and adds complexity. Option B is incorrect because requiring alumni to create Microsoft accounts and using Entra ID as the only provider would prevent alumni from using personal email accounts, which is a requirement. Option C is incorrect because using custom JavaScript for payment processing violates the low-code approach and may introduce security risks.

Answer

Create a custom web API in Azure to handle payments and call it from Power Pages using Liquid.

Answer

Configure Microsoft Entra ID as the only identity provider and require alumni to create a Microsoft account.

Answer

Use the Power Pages design studio to build the donation page with custom JavaScript to call the payment gateway API.

Question 10

A marketing team needs to create a public event registration page that captures attendee information and stores it in Dataverse. They want to design the page using drag-and-drop components without writing code. Which feature of Power Pages should they use?

Accepted Answer

Power Pages Studio. Power Pages Studio is the low-code/no-code design surface for building external-facing websites, including public event registration pages, using drag-and-drop components, templates, and Dataverse-backed forms. It lets the marketing team capture attendee data directly into Dataverse without writing code, which matches the requirement exactly.

Answer

Power Automate cloud flow

Answer

Power Apps canvas app

Answer

Power BI dashboard

Question 11

Refer to the exhibit. This Power Automate flow is triggered manually via HTTP request. The action 'Send_approval_email' sends an email. What is a potential issue with this flow design?

Accepted Answer

The flow does not include an approval action, only an email notification.. The flow is named 'Send_approval_email' and the question states it sends an email, but the design only performs a notification action rather than using Power Automate's dedicated Approvals connector (Start and wait for an approval). Without an approval action, the flow cannot capture an approve/reject decision or branch on the outcome, so it fails to fulfill its stated purpose. The HTTP request trigger is valid, authentication is a separate concern, and the email action is not deprecated.

Answer

The manual trigger cannot be used for HTTP requests.

Answer

The authentication parameter is missing.

Answer

The email action uses deprecated parameters.

Question 12

You need to automatically send an email notification when a new file is added to a SharePoint document library. Which trigger should you use in a Power Automate cloud flow?

Accepted Answer

When a file is created. The 'When a file is created' trigger is designed to start a flow when a new file appears in a SharePoint library. Option A is wrong because 'When a file is deleted' triggers on file removal, not creation. Option B is wrong because 'When a file is modified' triggers on updates, not new files. Option D is wrong because 'When a file is created or modified' includes modification events, which are not required for the specified requirement.

Answer

When a file is deleted

Answer

When a file is modified

Answer

When a file is created or modified

Question 13

Which TWO actions can be used to implement error handling in a Power Automate flow?

Accepted Answer

Use a Scope action to group actions and configure error handling. Option A is correct because the Scope action groups a set of actions into a single block, and its Run After settings can be configured so that a subsequent action (such as a Terminate or a notification) runs only when the Scope fails, times out, or is skipped, which is the standard pattern for try/catch-style error handling in Power Automate. Option D is correct because Run After settings define the dependency and outcome conditions (is successful, has failed, is skipped, has timed out) under which an action executes, and configuring an action to run after a previous action 'has failed' is the core mechanism for branching into error-handling logic. Option B is not the intended answer because a Condition action only evaluates data expressions at runtime and cannot by itself detect whether a prior action failed; failure detection is driven by Run After, not by Condition. Option C is not the intended answer because Compose merely outputs a value or expression for later use and does not provide any error-detection or error-handling behavior. Option E is not the intended answer because Apply to Each is a looping construct for iterating over arrays and does not implement error handling.

Answer

Add a Condition action to check for errors

Answer

Use a Compose action to store error details

Answer

Add an Apply to Each action

Question 14

Which TWO data sources can be directly connected to a canvas app without using a premium connector?

Accepted Answer

Excel (OneDrive/SharePoint). Option A (Excel in OneDrive/SharePoint) is correct because Excel workbooks stored in OneDrive for Business or SharePoint are accessed through the standard Excel connector, which is a non-premium (Standard) connector included with Power Apps. Option C (SharePoint) is correct because the SharePoint connector is also a Standard connector, allowing canvas apps to read and write SharePoint lists and libraries without a premium license. Option B (Microsoft Dataverse) is incorrect because Dataverse requires premium licensing/connectors. Option D (SQL Server) is incorrect because the SQL Server connector is a premium connector. Option E (Salesforce) is incorrect because the Salesforce connector is a premium connector.

Answer

Microsoft Dataverse

Answer

SQL Server

Answer

Salesforce

Question 15

Your organization uses Power Automate to automate onboarding processes. The flow creates a user in Microsoft Entra ID, assigns licenses, and sends a welcome email. Recently, the flow failed because the 'Create user' action returned 'PrivilegedOperationNotAllowed'. What is the most likely cause?

Accepted Answer

The service principal lacks required permissions in Microsoft Entra ID. The error 'PrivilegedOperationNotAllowed' from the 'Create user' action in Power Automate indicates that the connection or service principal used by the flow lacks the required Microsoft Graph permissions (such as User.ReadWrite.All or Directory.ReadWrite.All) in Microsoft Entra ID. This is a permissions issue, not a data or rate-limit issue. The service principal must be granted admin consent for the necessary Graph scopes.

Answer

The user already exists in the directory

Answer

The flow is using an expired connection

Answer

The flow has exceeded API rate limits
