PL-900 Practice Exam 51 — 20 Questions

Question 1

A company wants to use Power Platform to streamline its expense reporting process. Which TWO components can be used together to create a complete solution that allows employees to submit expenses, managers to approve them, and finance to analyze trends?

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

Accepted Answer

Power Apps. Power Apps allows employees to submit expenses via a custom app, while Power Automate handles the approval workflow and routes data to finance. Together they form a complete solution for submission and approval; Power BI can be added later for trend analysis but is not required for the core process.

Answer

Copilot Studio

Answer

Power BI

Answer

Power Pages

Question 2

Match each AI Builder model type to its use case.

Accepted Answer

Object Detection: Identify and locate specific objects in images.. The correct matches are: Object Detection identifies objects in images; Form Processing extracts data from forms; Text Classification categorizes text. Common confusions involve swapping these definitions.

Answer

Object Detection: Extract key-value pairs from forms.

Answer

Text Classification: Extract specific entities from text.

Question 3

Match each Power Apps license type to its description.

Accepted Answer

Power Apps per user plan: A user can run unlimited custom apps and access premium connectors.. Correct matches: Per user plan gives unlimited app access and premium connectors; per app plan is for a single app; Office 365 plan offers limited standard connector usage. Common confusions involve swapping the per user and per app definitions or overstating the Office 365 capabilities.

Answer

Power Apps per user plan: A user can run only one specific app.

Answer

Power Apps for Office 365: A user can run unlimited custom apps with premium connectors.

Question 4

An administrator configures a Power Platform tenant-level policy with the JSON shown. What is the effect of this policy?

Accepted Answer

It restricts all users from accessing any Power Platform environment. The JSON policy sets the 'blocked' property to true for all environments, which effectively denies all users (including admins) access to any Power Platform environment. This is a tenant-level restriction that overrides individual environment permissions, making it impossible for anyone to interact with Power Apps, Power Automate, or Power Virtual Agents within the tenant.

Answer

It allows only admins to manage environments

Answer

It prevents data export from environments

Answer

It blocks all users from creating new environments

Question 5

Match each Common Data Service (Dataverse) term to its description.

Accepted Answer

Entity: A container for records, similar to a database table.. The correct matches are Entity with 'container for records' and Attribute with 'field in an entity'. Common confusions include swapping Entity with Attribute and Relationship with Solution.

Answer

Relationship: A package that contains customizations and configurations.

Answer

Solution: An association between two entities.

Question 6

Which THREE of the following are capabilities of Power Apps?

Accepted Answer

Use AI Builder to add artificial intelligence. Power Apps allows users to connect to Microsoft 365 data (e.g., SharePoint, Outlook) for building business applications. It also integrates with AI Builder to add artificial intelligence capabilities. Additionally, Power Apps can run on mobile devices (iOS, Android, Windows) through the Power Apps mobile app. Option A is incorrect because complex workflow automations are a capability of Power Automate, not Power Apps. Option B is incorrect because real-time streaming analytics is not a core capability of Power Apps; it is more aligned with Azure Stream Analytics or Power BI.

Answer

Create complex workflow automations

Answer

Perform real-time streaming analytics

Question 7

A model-driven app includes a custom entity 'Project' with a lookup to 'Account'. Users need to see the account name and phone number on the Project form. What is the best way to display these fields?

Accepted Answer

Add a quick view form for the Account entity. A quick view form displays related data from the lookup entity (Account) directly on the Project form without storing duplicate fields. Option A is incorrect because calculated fields only compute values from existing fields within the same entity, not from related entities. Option B is incorrect because creating a new main form for the Project entity does not automatically show related Account fields. Option C is incorrect because adding account fields directly to the Project entity would duplicate data and violate normalization.

Answer

Use a calculated field on the Project entity

Answer

Create a new main form for the Project entity

Answer

Add the account fields directly to the Project entity

Question 8

A company uses Power BI to monitor manufacturing efficiency. The dataset includes a column 'RunTime' (in minutes) and 'DownTime' (in minutes). A user wants to calculate 'Availability' as (RunTime / (RunTime + DownTime)) * 100. Which DAX measure should be used?

Accepted Answer

Availability = DIVIDE(SUM([RunTime]), SUM([RunTime])+SUM([DownTime])) * 100. It uses the DIVIDE function to safely handle division by zero, and multiplies by 100 to express the result as a percentage. The formula sums RunTime and DownTime across all rows, then computes Availability = (Total RunTime / (Total RunTime + Total DownTime)) * 100, which matches the user's requirement exactly.

Answer

Availability = DIVIDE(SUM([RunTime]), SUM([RunTime])+SUM([DownTime]))

Answer

Availability = AVERAGE(Table[RunTime]) / (AVERAGE(Table[RunTime])+AVERAGE(Table[DownTime])) * 100

Answer

Availability = SUMX(Table, [RunTime]/([RunTime]+[DownTime])) * 100

Question 9

A canvas app includes a gallery that shows a list of customers. The app loads slowly when the gallery displays more than 500 records. What is the best way to improve performance?

Accepted Answer

Apply a filter to the gallery data source. Applying a filter to the gallery data source reduces the number of records loaded into the gallery, which improves performance because fewer records need to be transferred and rendered. Option A (non-delegable query) would actually worsen performance by loading all records locally. Option B (converting to a model-driven app) is a significant redesign and not a simple performance fix. Option D (increasing gallery height) does not affect the amount of data loaded; it only changes the display area.

Answer

Use a non-delegable query

Answer

Convert the app to a model-driven app

Answer

Increase the gallery height

Question 10

A Power Apps developer needs to create an app that uses AI Builder to extract information from invoices. The app should allow users to upload an image and then display extracted fields. Which control should be used to capture the image?

Accepted Answer

Add picture control. The Add picture control is the correct choice because it provides functionality for users to either take a photo using their device's camera or upload an existing image file. This is essential for the app's requirement to capture an invoice image and then use AI Builder to extract information from it. Option A (Camera control) is incorrect because it only allows real-time video capture and does not support file upload. Option C (Image control) is used solely to display images, not to capture them. Option D (Button control) can trigger actions but cannot directly capture images. Therefore, the Add picture control (B) is the only control that enables both photo capture and image upload, meeting the user's needs.

Answer

Camera control

Answer

Image control

Answer

Button control

Question 11

A company uses Power Automate to send approval emails when a new employee is added to Microsoft Entra ID. The approval flow fails intermittently with a '403 Forbidden' error. What is the most likely cause?

Accepted Answer

The connection used in the flow lacks appropriate permissions.. A '403 Forbidden' error typically indicates that the connection used in the flow does not have the necessary permissions to access Microsoft Entra ID. Option A is incorrect because license expiration would result in a different error, such as a '402 Payment Required'. Option B is incorrect because throttling limits cause '429 Too Many Requests' errors. Option D is incorrect because a deprecated connector would likely cause errors related to compatibility or connectivity, not a '403 Forbidden'.

Answer

The Microsoft Entra ID license has expired.

Answer

The flow is exceeding the API request throttle limit.

Answer

The Power Automate connector for Microsoft Entra ID is deprecated.

Question 12

A company is planning to build a Power Apps app for field service technicians to view and update work orders. The app must work offline and sync data when connected. Which TWO components are required to achieve offline capability?

Accepted Answer

Offline profile in Microsoft Dataverse. An offline profile in Microsoft Dataverse defines which tables, columns, and relationships are available when the app is disconnected. It enables the Power Apps mobile player to cache data locally and synchronize changes automatically when connectivity is restored. Without an offline profile, the app cannot determine what data to store or how to resolve conflicts during sync.

Answer

Power Automate flow triggered on data change

Answer

SharePoint list as data source

Answer

Common Data Service (Dataverse) database

Question 13

Refer to the exhibit. A Power Pages site has an entity permission configured as shown. A user assigned to the 'Support Staff' web role reports that they cannot see any cases when visiting the case list page. Other users with the same role can see cases. What is the most likely issue?

Accepted Answer

The scope should be 'User' instead of 'Global'.. The entity permission scope is set to 'Global', which grants access to all records of the entity. However, the user cannot see any cases because the scope should be 'User' to limit visibility to records owned by the user. Other users with the same role can see cases because they own cases, while this user does not own any cases.

Answer

The entity name is misspelled; it should be 'cases'.

Answer

The permission type should be 'Write' to see records.

Answer

The user is not assigned to the 'Support Staff' web role.

Question 14

Refer to the exhibit. The JSON defines a business process flow for expense reports in a model-driven app. How many stages must be completed before the process is considered complete?

Accepted Answer

Both stages (Submit and Approval).. Both stages 'Submit' and 'Approval' must be completed because the process flow includes them. Option C is correct. Option A is wrong because the process has two stages. Option B is wrong because the Approval stage also needs completion. Option D is wrong because the process does not have three stages.

Answer

Only the Approval stage.

Answer

All three stages (including a hidden stage).

Answer

Only the Submit stage.

Question 15

A healthcare organization is developing a Power Apps model-driven app for patient case management. The app uses Microsoft Dataverse as the data source and includes a custom table named 'Patient Cases' with columns: Patient Name, Case Type (choice: Consultation, Procedure, Follow-up), Assigned Doctor, Status (choice: New, In Progress, Completed), and Priority (choice: Low, Medium, High, Critical). The organization requires that when a case is created with Priority = 'Critical', an immediate notification must be sent to the Assigned Doctor via Microsoft Teams and the case must be automatically escalated to the manager if not resolved within 4 hours. Additionally, the app must use a Copilot to summarize patient history when a case is opened. The security team mandates that only doctors and managers can view cases assigned to them, and that all data access must be audited. Which combination of features should you implement to meet all requirements with minimal custom development?

Accepted Answer

Implement JavaScript in the form to call Power Automate for notifications, use owner teams to restrict access, add a custom Copilot page, and enable auditing via Power Apps settings.. It uses owner teams to provide record-level security, ensuring that doctors and managers only see cases assigned to them. JavaScript can call a Power Automate flow to send immediate Teams notifications when Priority is Critical, and the flow can implement a 4-hour escalation timer. Adding a custom Copilot page provides patient history summarization. Auditing can be enabled via Power Apps settings. This combination meets all requirements with minimal custom development. Option B is incorrect because field-level security profiles control access to specific fields, not record visibility; they cannot restrict users to only seeing records assigned to them. Option C is incorrect because sharing permissions are not designed for role-based, record-level access control; they are for ad-hoc sharing. Option D is incorrect because business rules cannot trigger notifications or set timers; they are for simple logic within forms.

Answer

Use a Dataverse business process flow to trigger Power Automate flows for notifications and escalation, configure field-level security profiles to restrict data access, enable Copilot in the model-driven app to summarize patient history, and enable audit logging on the Patient Cases table.

Answer

Design a Power Automate flow triggered on case creation that sends Teams notifications and waits for 4 hours before escalation, use sharing permissions to control access, and embed a Copilot AI Builder component.

Answer

Create business rules to send email notifications and set escalation timers, use role-based security for data access, add a Copilot chat control, and rely on Dataverse default auditing.

Question 16

Refer to the exhibit. A Power BI report connecting to the SalesDB database is slow. The exhibit shows a SQL Server activity snapshot. What is the most likely cause of the performance issue?

Accepted Answer

SPID 55 is blocked by SPID 54, causing delays. The exhibit shows SPID 55 (a SELECT query) in a 'suspended' state with a non-zero 'blocked_by' column value of 54, indicating it is waiting for a lock held by SPID 54. SPID 54 is in a 'sleeping' state but still holds locks, which blocks SPID 55 from proceeding. This blocking chain directly causes the report's slow performance, as the Power BI query cannot complete until the blocking session releases its locks.

Answer

The database server has insufficient memory

Answer

The SELECT query (SPID 55) is performing a table scan

Answer

The sleeping session (SPID 54) is using too much CPU

Question 17

Refer to the exhibit. A Power Pages site is configured with the given authentication settings. When a user clicks 'Sign In', they are redirected to Microsoft Entra ID, but after successful login, they are redirected back to the site and see an error. What is the most likely cause?

Accepted Answer

The redirectUrl is not registered in the Microsoft Entra ID app.. The redirectUrl must be registered as a reply URL in the Microsoft Entra ID app registration. If it is missing, the login fails.

Answer

The clientId is invalid.

Answer

The tenantId is incorrect.

Answer

The site requires HTTPS but is using HTTP.

Question 18

A healthcare organization uses Power Pages to provide a patient portal where patients can view their medical records, schedule appointments, and communicate with their care team. The portal uses Dataverse with Microsoft Entra ID (formerly Azure AD) as the identity provider. Due to regulatory requirements, the portal must ensure that session timeouts occur after 15 minutes of inactivity, and any unsaved data in forms should be preserved for up to 24 hours. Additionally, the solution must log all user activity for auditing. You need to configure these requirements in Power Pages. What should you do?

Accepted Answer

In the Power Pages admin center, configure 'Session Timeout' to 15 minutes, enable 'Save Progress' on forms with 24-hour retention, and enable 'Audit logging' to capture user activity.. Power Pages provides built-in settings to meet all three requirements directly from the Power Pages admin center. 'Session Timeout' can be set to 15 minutes to enforce inactivity logout. 'Save Progress' on forms with a 24-hour retention period preserves unsaved data. 'Audit logging' captures user activity and logs it to Dataverse. Option A is incorrect because Azure Monitor is not integrated into Power Pages natively and modifying IIS settings is not applicable in the Power Pages managed environment. Option C is incorrect because Azure AD Conditional Access policies control authentication but do not manage form data preservation or session timeout within the portal. Option D is incorrect because developing custom JavaScript and Power Automate flows is overly complex and not necessary when built-in settings are available.

Answer

Use Azure Monitor to track user activity and configure the web application session timeout in the IIS settings via the portal's hosting environment.

Answer

Configure session timeout using Azure AD Conditional Access policies and use Power Automate to save form data periodically to Dataverse.

Answer

Develop custom JavaScript to track inactivity and trigger a Power Automate flow that saves form data to a Dataverse table.

Question 19

Your organization wants to allow employees to submit help desk tickets through a mobile app. The solution must be low-code and integrate with Microsoft Teams. Which Microsoft Power Platform component should you use?

Accepted Answer

Power Apps. Power Apps is the correct component because it enables the creation of custom mobile apps with low-code development, allowing employees to submit help desk tickets directly from their mobile devices. It integrates natively with Microsoft Teams through the Power Apps app in Teams, enabling users to access and submit tickets without leaving the Teams interface. This aligns with the requirement for a low-code solution that works within the Teams ecosystem.

Answer

Power Virtual Agents

Answer

Power Automate

Answer

Power BI

Question 20

A marketing department wants to create a custom portal where external partners can submit project proposals and track their status. Which Power Platform product should they use?

Accepted Answer

Power Apps portal (now Power Pages). Power Apps portals (now Power Pages) is the correct choice because it enables organizations to create low-code, externally facing websites that allow external users—such as partners—to sign in, submit project proposals, and track their status. It integrates with Microsoft Dataverse to store and manage the proposal data, and supports role-based access control to ensure partners only see their own submissions.

Answer

Power Automate

Answer

Power Virtual Agents

Answer

Power BI
