PL-900 Practice Test 50 — 15 Questions

Question 1

You have a Power Automate flow that uses a Dataverse connector to update a record when an approval is completed. The flow previously worked but now fails with an error 'Connection not found'. You verify that the connection to Dataverse still exists and the user has appropriate permissions. What is the most likely cause?

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

Accepted Answer

The Dataverse environment was deleted or renamed. If the connection exists and permissions are fine, the trigger or action might be using a deleted or renamed environment. The Dataverse environment might have been recently changed or deleted. Other options like license expiry or service outage would show different errors.

Answer

The Microsoft 365 tenant has a service outage

Answer

The flow owner's Power Automate license expired

Answer

The approval action is not configured correctly

Question 2

A user sees the exhibit error when opening a Power BI report in the service. What is the most likely cause?

Accepted Answer

The data source connection in the service was modified. The error shown in the exhibit is a typical 'Couldn't load the data for this visual' message that occurs when the data source connection defined in the Power BI service has been changed (e.g., server name, database name, or authentication method) but the report's underlying dataset still references the old connection. This mismatch prevents the service from retrieving data, even if the gateway is online and credentials are valid. Option D is correct because modifying the data source connection in the service without updating the dataset's connection string breaks the data retrieval pipeline.

Answer

The scheduled refresh failed due to credentials

Answer

The on-premises data gateway is offline

Answer

The dataset was deleted from the workspace

Question 3

A company wants to build a Power Pages site that allows external partners to submit project proposals. The proposals should be stored in Dataverse. What is the first step to create the necessary data structure?

Accepted Answer

Create a custom table in Dataverse. To store project proposals submitted via a Power Pages site, you need a custom table in Dataverse to define the data structure. Power Pages uses Dataverse as its primary data source. Option A is incorrect because Power Automate creates flows, not data structures. Option B is incorrect because Power Pages does not use SharePoint lists natively; it relies on Dataverse. Option D is incorrect because Excel files in OneDrive are not a suitable data source for Power Pages.

Answer

Create a Power Automate flow to collect data

Answer

Create a SharePoint list

Answer

Create an Excel file in OneDrive

Question 4

You are reviewing a Power Automate flow definition. The flow should send an email when a new invoice file is added to a SharePoint folder. However, the flow is not triggering. What is the most likely cause?

Accepted Answer

The folder path '/documents/invoices' is incorrect or the flow lacks permissions.. The most likely cause is that the folder path '/documents/invoices' is incorrect or the flow lacks permissions. Power Automate triggers for SharePoint require exact folder paths and appropriate access rights to monitor file additions. If the path is misspelled, uses a relative path instead of a server-relative path, or the service account does not have read permissions on the folder, the trigger will not fire.

Answer

The email action uses an incorrect dynamic expression.

Answer

The flow needs a 'Get file content' action before sending email.

Answer

The SharePoint trigger requires a 'When a file is created or modified' trigger instead.

Question 5

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

Question 6

A company wants to allow external partners to access a Power Apps portal without requiring a Microsoft Entra ID account. What should the administrator configure?

Accepted Answer

Configure the portal to use local authentication with username and password. Power Apps portals support local authentication, which allows external users to sign up and sign in using a username and password without requiring a Microsoft Entra ID account. This is the appropriate method when the goal is to grant access to partners who do not have or need Microsoft Entra ID credentials.

Answer

Create Microsoft Entra ID guest accounts for each partner

Answer

Share the Power Apps app directly with the partners

Answer

Enable Microsoft Entra ID B2B collaboration and invite partners

Question 7

A nonprofit organization needs to track donations and volunteers using a custom app without writing code. Which Power Platform tool should they use?

Question 9

A manufacturing company wants to use Power Platform to improve operational efficiency. Which TWO benefits of using Microsoft Power Platform are most relevant?

Accepted Answer

Build custom apps without extensive coding. Microsoft Power Platform enables citizen developers to build custom apps using low-code tools like Power Apps, which significantly reduces the need for extensive traditional coding. This aligns directly with the company's goal of improving operational efficiency by allowing rapid application development without deep programming expertise.

Answer

Answer

Eliminate the need for user authentication

Question 10

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 11

Refer to the exhibit. You are reviewing a Power Apps app definition. Based on the exhibit, which connector does the app use?

Accepted Answer

Microsoft Dataverse. The exhibit shows a Power Apps app definition that includes a reference to a Microsoft Dataverse table (e.g., 'Accounts' or 'Contacts') as the data source. Dataverse is the native data platform for Power Apps, providing relational tables, business logic, and security directly within the Power Platform. The connector used is Microsoft Dataverse, which is the default connector when building canvas or model-driven apps with Dataverse tables.

Answer

Office 365 Users

Answer

SQL Server

Answer

SharePoint

Question 12

Your company uses Power Automate to handle approvals for purchase orders. You need to create a flow that triggers when an item is added to a SharePoint list, checks if the amount exceeds $10,000, and if so, sends an approval request to the finance manager. If approved, the item status should be updated to 'Approved'. Which type of flow should you use?

Accepted Answer

Automated cloud flow. An automated cloud flow can trigger on new SharePoint item, include a condition to check amount, use an approval action, and conditionally update the item. Desktop flows are for desktop automation. Business process flows guide users. Instant flows need manual trigger.

Answer

Business process flow

Answer

Instant cloud flow

Answer

Desktop flow

Question 13

Your company wants to use AI to analyze customer feedback from surveys and identify common themes. The solution should be built using Microsoft Power Platform. Which capability should you use?

Accepted Answer

AI Builder. AI Builder provides prebuilt AI models for text classification and entity extraction, enabling analysis of customer feedback to identify common themes. Option A is incorrect because Power Virtual Agents is designed for building conversational chatbots, not for text analysis. Option C is incorrect because Power BI with natural language queries allows users to ask questions about data but does not automatically analyze text for themes. Option D is incorrect because Power Automate is a workflow automation tool that does not include built-in AI capabilities for text analysis.

Answer

Power Virtual Agents with a topic

Answer

Power BI with natural language queries

Answer

Power Automate with a custom connector

Question 14

An organization wants to implement AI-driven insights for sales forecasting using historical data. Which Power Platform capability should they use?

Question 15

An organization has deployed a Power Automate flow that processes sensitive customer data. The security team requires that the flow's connections use managed identities instead of user credentials. What should the administrator do?

Accepted Answer

Use managed identities for the connections where supported.. Managed identities in Power Automate allow connections to authenticate to Azure resources without storing credentials, directly addressing the security team's requirement to avoid user credentials. Managed identities are a secure, Azure AD-backed identity that can be assigned to a flow or environment, eliminating the need for shared secrets or user context.

Answer

Share the flow with the security team and have them modify the connections.

Answer

Use a service principal with a certificate and store the certificate in the flow's environment.

Answer

Store the user credentials in Azure Key Vault and reference them in the flow.
