PL-900 Practice Exam 57 — 20 Questions

Question 1

A company uses Power Automate to automate approval workflows. An employee reports that an approval request sent to their manager is not being delivered. The manager is listed in Microsoft Entra ID with the correct email address. What is the most likely cause?

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

Accepted Answer

The manager does not have a Power Automate license.. The most likely cause is that the manager does not have a Power Automate license (Option A). For approval flows in Power Automate, the approver must have a license that includes Power Automate rights (such as a Power Automate per-user plan or a Microsoft 365 license that includes Power Automate capabilities). Even if the manager's email is correctly configured in Microsoft Entra ID, without the appropriate license the approval request cannot be delivered. Option B (deprecated trigger) is unlikely because a deprecated trigger would cause the flow to fail to run entirely, not specifically fail to deliver an approval. Option C (wrong response options) would only affect the approver's ability to respond, not the delivery of the request. Option D (quota limit) would pause the flow itself, not prevent delivery of an individual approval request.

Answer

The flow is using a deprecated trigger.

Answer

The approval is configured with the wrong response options.

Answer

The flow is paused due to a quota limit.

Question 2

Match each Microsoft Dataverse security concept to its definition.

Accepted Answer

Role-based security: Controls access based on a user's role membership.. Dataverse uses role-based security as its foundation. Role-based security controls access via user roles, field-level security restricts specific attributes, row-level security governs records, and team-based security applies roles to groups. Common mistakes include confusing field-level with row-level or mixing definition of role-based security.

Answer

Role-based security: Restricts access to specific records in an entity.

Answer

Field-level security: Controls access based on user's role membership.

Question 3

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. 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.

Question 4

A financial services company uses Power Automate to process loan applications. The flow uses the ‘When a new email arrives’ trigger from a shared mailbox. The flow recently stopped working after an admin changed the mailbox permissions. What is the most likely cause?

Accepted Answer

The mailbox connection lost permissions to access the mailbox. The flow uses the 'When a new email arrives' trigger, which relies on a connection to the shared mailbox. When an admin changes mailbox permissions, the existing connection loses its authorization to access the mailbox, causing the trigger to fail. This is the most direct cause because the connection object in Power Automate must have valid permissions to read emails from the specified mailbox.

Answer

The mailbox exceeded its storage limit

Answer

The flow owner's Power Automate license was deleted

Answer

The flow was transferred to another owner

Question 5

Drag and drop the steps to create a custom connector in Power Automate in the correct order.

Accepted Answer

Start from blank, then Define basic information, then Configure endpoints, then Test, then Create connector. Custom connectors start from blank, define info, configure endpoints, test, then create.

Answer

Start from blank, then Configure endpoints, then Define basic information, then Test, then Create connector

Answer

Start from blank, then Define basic information, then Test, then Configure endpoints, then Create connector

Answer

Define basic information, then Start from blank, then Configure endpoints, then Test, then Create connector

Question 6

Which TWO actions are supported by Power BI to share a report with external users who do not have an Azure Active Directory (Azure AD) account in the tenant?

Accepted Answer

Publish the report to the web (embed code) and share the link.. Power BI's 'Publish to web' feature generates an embed code that creates a publicly accessible URL, allowing anyone with the link to view the report without requiring an Azure AD account. This bypasses tenant-level authentication entirely, making it suitable for sharing with external users who lack Azure AD credentials in the organization's tenant.

Answer

Share the report directly by entering the external user's email address.

Answer

Export the report to PDF and share the file via a shared drive.

Answer

Send the report as an email attachment to the external user.

Question 7

Question 8

A university uses Power Pages to create an alumni portal where graduates can update their contact information, register for events, and make donations. The portal uses Dataverse and allows both authenticated and anonymous access. The university wants to comply with GDPR and allow users to request deletion of their personal data. They need a mechanism for users to submit a deletion request, which then triggers a manual review process before data is deleted. You need to implement this in Power Pages with minimal effort. What should you do?

Accepted Answer

Build a custom form in Power Pages that submits to a Dataverse table 'Deletion Requests', and create a Power Automate flow that notifies admins and performs the deletion after approval.. Power Pages allows creating custom forms that submit data to Dataverse tables. By building a form that writes to a 'Deletion Requests' table, you can then trigger a Power Automate flow when a new record is created. The flow can send a notification to admins and, after manual approval, perform the actual deletion from Dataverse. This approach requires minimal custom code and leverages existing Power Platform integrations. Option A (manual email) is not automated and lacks audit trail. Option B (Azure Logic App with custom JavaScript) requires additional external configuration and custom scripting. Option C (legacy Power Apps portal) is outdated; Power Pages is the current product and offers native Dataverse integration. Option D is the correct and minimal-effort solution.

Answer

Add a hyperlink to the portal that sends an email to an admin mailbox, and have admins manually delete the data.

Answer

Use an Azure Logic App to expose an HTTP endpoint, and have the portal send data via a custom JavaScript call.

Answer

Create a Power Apps portal (legacy) form that writes to a 'Deletion Requests' Dataverse table and configure a Business Process Flow for review.

Question 9

You are a Power Platform administrator. A user reports that they are unable to share a canvas app with external users. What is the most likely cause?

Accepted Answer

The environment is not enabled for external sharing.. External sharing of canvas apps is controlled at the environment level in the Power Platform admin center. By default, external sharing is disabled for environments, and an administrator must explicitly enable it under the environment's settings. Without this setting enabled, users cannot share canvas apps with external users, even if they have the appropriate permissions.

Answer

The environment is a sandbox environment, which does not support external sharing.

Answer

The environment has a data loss prevention (DLP) policy that blocks sharing.

Answer

External users must have a Power Apps license to access the app.

Question 10

A Power Pages site is experiencing slow load times because it loads all records from a large Dataverse table. The site uses a list component to display data. What is the most effective way to improve performance without custom code?

Accepted Answer

Add a FetchXML filter to the list to load only the necessary records.. Power Pages list components can use FetchXML to filter data server-side, reducing data transfer. Paging in the browser still loads all data if not filtered. OData filters are less efficient. Caching is not a standard feature.

Answer

Use an OData query parameter to limit the number of records.

Answer

Enable client-side caching in the site settings.

Answer

Implement server-side paging by setting the 'Page Size' property in the list configuration.

Question 11

Refer to the exhibit. A Power Pages developer uses the Liquid snippet shown in a web template. What will be displayed to an unauthenticated user viewing the page?

Accepted Answer

Welcome, guest!. The 'user' object is null for unauthenticated users, so the else branch executes, showing 'Welcome, guest!'.

Answer

An empty paragraph.

Answer

Nothing; the page will error.

Answer

Welcome!

Question 12

A global consulting firm uses Power Platform with environments in multiple regions. They need to enforce data loss prevention (DLP) policies that are consistent across all environments, but allow exceptions for specific connectors in a single environment used for a high-security client project. Which three components should they configure?

Accepted Answer

Environment-level DLP policy. Environment-level DLP policies can be created to override tenant-level policies for specific environments. The tenant-level DLP policy provides a baseline. Connector classification (e.g., Blocked, Business, Non-business) is part of DLP policy configuration.

Question 13

You are the Power Platform administrator for Contoso Ltd., a retail company with 500 employees. The company uses Microsoft 365 and has recently adopted Power Platform. The IT department manages a Power Apps canvas app used by the sales team to track customer interactions. The app connects to a Microsoft Dataverse table named 'Customer Interactions' with columns: CustomerID (text), InteractionDate (date), Notes (text), and SalesPerson (text). The app was working fine for three months, but starting last week, users report that the app loads slowly, sometimes timing out, and the 'Customer Interactions' table shows duplicate records. Upon investigation, you find that the app uses a 'Patch' function to create records, and the 'OnStart' property loads all records from the table using 'Filter(Customer Interactions, SalesPerson = User().FullName)' to show only the current user's records. The Dataverse table has grown to 50,000 rows. Additionally, some users have accidentally created multiple submissions by double-clicking the submit button. You need to resolve the performance and duplicate issues with minimal disruption. What should you do?

Accepted Answer

Modify the 'Submit' button to set its 'DisplayMode' to 'Disabled' after the first click to prevent double submission, and change the 'OnStart' filter to delegate by ensuring the 'SalesPerson' column is indexed in Dataverse and using 'Filter(Customer Interactions, SalesPerson = User().FullName)' with delegation enabled.. It addresses both performance and duplicate issues directly. Disabling the submit button after the first click prevents double submissions, a common cause of duplicates in canvas apps. Indexing the SalesPerson column in Dataverse ensures the Filter function delegates, meaning the query runs on the server side and only returns relevant rows, drastically reducing data transfer and load times compared to pulling all 50,000 rows client-side.

Answer

Replace the 'Patch' function with 'Collect' in the app and use the 'Distinct' function to remove duplicates from the table every night via a Power Automate flow.

Answer

Increase the 'Data row limit' for the 'Customer Interactions' table in the app settings to 500 and add a 'Remove duplicates' step in the app's 'OnStart'.

Answer

Remove the 'Filter' from 'OnStart' and load all records into a collection, then use 'Filter' on the collection to show current user's records.

Question 14

Refer to the exhibit. A Power Automate environment has two flows. Flow1 triggers on item creation and sends an email then updates the item. Flow2 triggers on email arrival, creates an item, and sends an approval. If an email arrives that triggers Flow2, and Flow2's first action creates an item, will Flow1 also trigger?

Accepted Answer

Yes, because the item creation will trigger Flow1.. Flow1 triggers on item creation, so when Flow2's first action creates an item, that creation event fires the trigger for Flow1. Power Automate allows multiple flows to respond to the same event independently, so Flow1 will execute as a separate instance. This is why option C is correct.

Answer

No, because Flow2 runs in a separate context.

Answer

Yes, but only if both flows are in the same solution.

Answer

No, because triggers are disabled during flow runs.

Question 15

A retail company uses Power Apps to manage inventory. Store managers report that the app loads slowly during peak hours. Which action should the administrator take to improve performance?

Accepted Answer

Enable app caching in the app settings.. Enabling app caching in Power Apps stores app resources locally on the user's device, reducing load times by minimizing repeated downloads of the app definition and data requests during peak usage. This directly addresses the slow loading reported by store managers by leveraging client-side caching to improve performance.

Answer

Create a Power Automate flow to preload data.

Answer

Increase the data source row limit to 2000.

Answer

Add more screens to distribute data entry.

Question 16

A university uses Power BI to visualize student performance data. They want to allow department heads to create their own reports using the same dataset but without seeing other departments' data. Which TWO features should they implement?

Accepted Answer

Power BI workspace. Row-level security (RLS) restricts data access by user. Power BI workspaces allow organizing content. Power BI apps can distribute reports, but RLS is key for data security. Power Automate is not needed.

Answer

Data gateway

Question 18

You are a Power Platform administrator. A user reports that a Power Automate flow that connects to SharePoint Online fails intermittently with a '403 Forbidden' error. The flow uses a service principal with application permissions. What is the most likely cause?

Accepted Answer

The service principal lacks the necessary SharePoint API permissions or admin consent.. A 403 Forbidden error specifically indicates that the server understood the request but refuses to authorize it. Since the flow uses a service principal with application permissions, the most likely cause is that the service principal lacks the necessary SharePoint API permissions or that admin consent has not been granted for those permissions. Without proper permissions or consent, SharePoint Online rejects the request regardless of authentication validity.

Answer

The flow is exceeding the SharePoint Online API throttling limits.

Answer

The service principal has been disabled in Microsoft Entra ID.

Answer

SharePoint Online is experiencing a service outage.

Question 19

Your company has a Power BI dashboard that displays sales data from a SQL Server database hosted on-premises. The dashboard is used by the sales team to monitor daily performance. Recently, the dashboard has been showing stale data. The data is supposed to refresh every night at 2:00 AM. You have confirmed that the SQL Server database is updated with new data each night. However, the Power BI dataset refresh fails. You need to ensure that the dashboard shows up-to-date data every morning. What should you do?

Accepted Answer

Install and configure an on-premises data gateway and assign it to the dataset.. An on-premises data gateway is required to bridge the connection between Power BI (a cloud service) and an on-premises SQL Server database. Since the dataset refresh fails despite the database being updated, the gateway is either missing or misconfigured. Installing and configuring the gateway allows the scheduled refresh to access the on-premises data source securely, ensuring the dashboard displays up-to-date data each morning.

Answer

Disable scheduled refresh and manually refresh the dataset every morning.

Answer

Change the data source to an Excel file stored in SharePoint Online.

Answer

Republish the Power BI report from Power BI Desktop.

Question 20

A company uses Power Automate flows that access Microsoft SharePoint and Microsoft Dataverse. They want to prevent data from leaving the organization. What should they configure?

Accepted Answer

Create a data loss prevention (DLP) policy in the Power Platform admin center that blocks sharing data with external connectors.. Data Loss Prevention (DLP) policies in the Power Platform admin center are specifically designed to prevent data from leaving the organization by controlling which connectors can share data. By blocking external connectors, the policy ensures that SharePoint and Dataverse data cannot be sent to unauthorized external services, directly addressing the requirement.

Answer

Configure Microsoft Purview to automatically classify and protect data in Power Automate.

Answer

Enable Microsoft Defender XDR to monitor for suspicious data transfers.

Answer

Apply Microsoft Entra ID Conditional Access policies to require managed devices.
