PL-900 Practice Exam 2 — 20 Questions

Question 1

A company wants to extend their existing copilot built with Copilot Studio to trigger a workflow when an employee requests time off. The workflow must create a record in a Dataverse table and send an approval email. What should the copilot developer use?

Accepted Answer

Add a Power Automate flow as a plugin. Option D is correct because Copilot Studio allows extending a copilot's capabilities by adding a Power Automate flow as a plugin. This enables the copilot to trigger a workflow that creates a record in a Dataverse table and sends an approval email, directly fulfilling the requirement without needing to embed an app or use AI Builder.

Answer

Embed a Power Apps canvas app

Answer

Use AI Builder to create a model

Answer

Configure the Dataverse connector directly

Question 2

A flow fails with the error: 'GatewayTimeout'. The flow connects to an on-premises SQL Server via a data gateway. What is the most likely cause?

Accepted Answer

The on-premises data gateway is not running or unreachable. The 'GatewayTimeout' error indicates that the flow successfully reached the on-premises data gateway but the gateway did not respond within the expected time frame. This typically occurs when the gateway service is not running, the machine hosting the gateway is offline, or network connectivity between the gateway and the SQL Server is broken. Incorrect credentials or missing tables would produce different errors (e.g., 'Login failed' or 'Invalid object name').

Answer

The SQL login credentials are incorrect

Answer

The SQL table does not exist

Answer

The flow trigger did not fire

Question 3

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 4

A company wants to automate sending a welcome email to new employees after they are added to a SharePoint list. Which type of trigger should be used in the Power Automate flow?

Accepted Answer

When an item is created - SharePoint. The 'When an item is created - SharePoint' trigger is the correct choice because it initiates the flow automatically whenever a new item (in this case, a new employee record) is added to the specified SharePoint list. This event-driven trigger eliminates the need for manual intervention, making it ideal for automating the welcome email process immediately upon creation.

Answer

For a selected item - SharePoint

Answer

Recurrence

Answer

Start and wait for an approval

Question 5

You have a Power Automate flow that sends an email notification when a new file is added to a SharePoint document library. Users report that emails are not being sent for some files. What is the most likely cause?

Accepted Answer

A trigger condition is filtering out some files. Option C is correct because trigger conditions in Power Automate allow you to define expressions that must evaluate to true for the flow to run. If a condition is configured to filter out certain files (e.g., based on file name, metadata, or size), those files will not trigger the flow, and no email will be sent. This is the most likely cause when emails are missing for some files but not all.

Answer

The flow uses a premium connector that requires a license

Answer

The file is being co-authored by multiple users

Answer

The file content contains sensitive information

Question 6

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

Dataverse

Answer

Power BI

Answer

Power Apps

Question 7

A company wants to create a custom copilot that answers employee questions about IT policies. The copilot must use existing SharePoint documents as a knowledge source. Which feature of Microsoft Copilot Studio should the company use?

Accepted Answer

Add a knowledge source. Option D is correct because the 'Add a knowledge source' feature in Microsoft Copilot Studio allows you to connect a copilot to existing SharePoint document libraries, enabling it to retrieve and answer questions based on the content of those documents. This is the direct mechanism for grounding a custom copilot with enterprise content without requiring additional development.

Answer

Generative AI feature

Answer

Power Automate cloud flow

Answer

Copilot for Microsoft 365

Question 8

A company has deployed a custom copilot built with Microsoft Copilot Studio. Users report that the copilot sometimes provides outdated information. The knowledge sources are SharePoint sites and public websites. The copilot uses Generative AI to formulate answers. What should the administrator do to improve the accuracy of the copilot's responses?

Accepted Answer

Refresh the knowledge sources periodically. Option C is correct because the copilot's knowledge sources (SharePoint sites and public websites) are not automatically refreshed in real time. By periodically refreshing these sources, the administrator ensures the copilot's generative AI has access to the most current content, directly addressing the issue of outdated information.

Answer

Enable the 'Show citations' option

Answer

Reduce the number of topics

Answer

Turn off Generative AI for responses

Question 9

A sales manager wants to track leads and opportunities without custom development. Which Power Platform component should they use?

Accepted Answer

Power Apps (model-driven app). A model-driven app in Power Apps is designed for data-centric business processes like lead and opportunity tracking, providing out-of-the-box tables, forms, and views without custom development. It leverages the Dataverse to store and manage structured data, making it ideal for a sales manager to track leads and opportunities through a pre-configured, customizable interface.

Answer

Power BI

Answer

Power Virtual Agents

Answer

Power Automate

Question 10

A company's IT department is overwhelmed with password reset requests. They want to allow employees to reset passwords themselves using a conversational interface. Which Power Platform tool should they use?

Accepted Answer

Power Virtual Agents. Power Virtual Agents (C) is the correct tool because it enables the creation of conversational AI chatbots that can handle password reset requests through natural language interactions. It integrates with Azure Active Directory and other identity systems to allow employees to securely reset their own passwords without IT intervention, reducing the helpdesk workload.

Answer

Answer

Power Apps

Answer

Power Automate

Question 11

A developer creates a canvas app to display orders from Microsoft Dataverse. The app uses the gallery and data configuration shown in the exhibit. When the app runs, the gallery shows orders but the 'View Details' button does nothing when tapped. What is the most likely cause?

Accepted Answer

The target screen 'OrderDetailScreen' does not exist in the app. Option B is correct because the Navigate function in the button's OnSelect property references 'OrderDetailScreen', but if that screen does not exist in the app, the function cannot execute, causing the button to appear unresponsive. The gallery displays orders correctly, confirming the data source and Items property are functional, isolating the issue to the navigation target.

Answer

The button's OnSelect property has a syntax error

Answer

The Dataverse connection requires user authentication

Answer

The gallery's items property is misconfigured

Question 12

An organization is configuring a custom connector in Power Automate to connect to Salesforce. The exhibit shows a snippet of the connector definition. However, when attempting to test the connection, the authentication fails. What is the most likely cause?

Accepted Answer

The OAuth flow type is incorrectly set to 'accessCode' instead of 'authorizationCode'.. Option A is correct because the OAuth 2.0 flow type 'accessCode' is not a valid OAuth 2.0 grant type. The correct value for the authorization code grant type is 'authorizationCode'. Power Automate custom connectors require this exact string to properly initiate the OAuth 2.0 authorization code flow with Salesforce. Using 'accessCode' causes the authentication handshake to fail because the connector cannot map the flow to a supported OAuth grant.

Answer

The scopes array is missing the 'id' scope.

Answer

The apiVersion is not supported by Power Automate.

Answer

The serviceUrl should point to the Salesforce instance, not login.salesforce.com.

Question 13

Refer to the exhibit. A Power BI developer imported the JSON data into a Power BI data model. When creating a report, they notice that the 'Sales' table does not display the product name. What is the most likely cause?

Accepted Answer

The relationship between Sales and Product tables is not active or is misconfigured.. Option D is correct because the most likely cause is that the relationship between the Sales and Product tables is either inactive or misconfigured. In Power BI, even when a relationship exists, if it is set to inactive (e.g., using a bidirectional filter or a different cardinality), the report will not automatically propagate the ProductName from the Product table to the Sales table. This prevents the product name from displaying in the report, even though the data is present in the model.

Answer

No relationship is defined between the tables.

Answer

The Sales table and Product table are from different data sources.

Answer

The 'ProductName' column is missing from the Product table.

Question 14

A customer interacts with a Microsoft Copilot Studio bot and says, "I want to check order status." The bot responds with "Please provide your order number." The customer then types their order number, but the bot does not proceed. Which of the following is the most likely cause?

Accepted Answer

The order number entity is not recognized or extracted from the user's input.. The bot fails to proceed because it cannot extract the order number entity from the user's input. In Microsoft Copilot Studio, entities are used to identify and capture specific data types (like order numbers) from user utterances. If the entity is not configured, not trained, or the user's input format doesn't match the entity pattern, the bot will not recognize the order number and cannot pass it to the next topic or action, causing the conversation to stall.

Answer

The bot is stuck in the Fallback topic.

Answer

The trigger phrase does not match exactly.

Answer

The "Redirect to Order Lookup topic" action is placed before the message actions.

Question 15

Which TWO actions can be performed using Microsoft Copilot Studio without writing custom code?

Accepted Answer

Trigger a Power Automate flow from a topic.. Option A is correct because Microsoft Copilot Studio allows you to trigger a Power Automate flow directly from a topic without writing any custom code. This is achieved by adding a 'Call an action' node within a topic and selecting a Power Automate flow, enabling the copilot to execute automated workflows seamlessly.

Answer

Integrate with a custom API by writing JavaScript code.

Answer

Train the copilot with a custom machine learning model.

Answer

Deploy the copilot to a third-party website using custom HTML.

Question 16

A manufacturing company uses Microsoft Power Platform to manage its inventory. They have a Power Apps app that allows warehouse staff to scan items and update quantities in a SharePoint list. Recently, the app has been slow to load and occasionally times out when scanning multiple items in quick succession. The IT team suspects the issue is related to the data source connection. They want to improve performance without changing the user interface. The company has a Microsoft 365 E3 subscription and all data resides in SharePoint Online. What should the IT team do first?

Accepted Answer

Optimize the Power Apps by enabling delegation for the SharePoint connector.. Option C is correct because enabling delegation for the SharePoint connector allows Power Apps to offload filtering and sorting operations to SharePoint Online, rather than retrieving all rows to the client. This reduces the amount of data transferred over the network, which directly addresses the slow load and timeout issues when scanning multiple items in quick succession, without changing the user interface.

Answer

Implement a timer control to delay scanning between items.

Answer

Migrate the SharePoint list to an on-premises SQL Server database.

Answer

Replace SharePoint with Microsoft Dataverse for better performance.

Question 17

Which TWO of the following are components of Power Platform? (Choose two.)

Accepted Answer

Question 18

You are designing a Power Automate flow to approve expense reports. The flow must allow managers to approve or reject directly from the email notification without signing in. Which action should you use?

Accepted Answer

Start and wait for an approval. The 'Start and wait for an approval' action is specifically designed to send an approval request via email or the Power Automate mobile app, and it allows recipients to approve or reject directly from the email notification without needing to sign in, using adaptive cards or lightweight approval buttons. This meets the requirement for manager approval without authentication.

Answer

Create a file

Answer

Send an email (V2)

Answer

Send an HTTP request

Question 19

Which TWO Microsoft Power Platform solutions are designed to be used together to build a complete customer feedback analysis system that collects feedback from multiple channels, processes sentiment, and provides actionable insights?

Accepted Answer

AI Builder. AI Builder (D) is correct because it provides pre-built AI models for sentiment analysis, which can process feedback text from multiple channels to determine positive, negative, or neutral sentiment. Power Automate (E) is correct because it orchestrates the collection of feedback from various sources (e.g., email, forms, social media) and triggers actions based on sentiment results, enabling a complete automated feedback analysis pipeline.

Answer

Dataverse

Answer

Power Apps

Answer

Power BI

Question 20

A company uses Power Automate to send approval requests. The flow is triggered when a new item is added to a SharePoint list. However, the flow fails when the item contains a large attachment. What is the most likely cause?

Accepted Answer

The attachment exceeds the maximum file size allowed by Power Automate. Power Automate imposes a maximum file size limit for attachments processed within flows. When a SharePoint list item includes a large attachment that exceeds this limit, the flow fails during the approval action because the attachment data cannot be transmitted. This is a known constraint in Power Automate, typically around 100 MB for standard connectors, and is the most direct cause of the failure described.

Answer

The flow is using the wrong trigger

Answer

The approval action is not configured for attachments

Answer

The SharePoint list is not properly configured for large files
