PL-900 Describe the business value of Microsoft Power Platform — 20 Questions

Question 1

A small business owner wants to create a customer loyalty program. They want customers to earn points for purchases and redeem them for discounts.

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

Accepted Answer

Power Apps, Power Automate, and Dataverse. Power Apps (canvas app) can create a mobile-friendly app with minimal coding, meeting the need for a customer-facing interface. Power Automate handles point calculations and redemption logic through automated workflows. Dataverse provides a scalable and secure data store for customer points and redemptions. Option A is incorrect because Power BI is for analytics, not for building a transactional app. Option C is overkill with AI Builder, which is unnecessary for basic point tracking. Option D is incorrect because Power Pages is for external websites, not a mobile app, and SharePoint lacks the relational data capabilities needed for point management.

Answer

Power BI, Power Automate, and Dataverse

Answer

Power Apps, AI Builder, and Dataverse

Answer

Power Pages, Power Automate, and SharePoint

Question 2

A large retail chain uses Power Platform to manage store operations. They have 500 stores, each with a tablet running a Power Apps canvas app for inventory management. The app connects to Dataverse. Recently, store managers reported that the app is slow during peak hours. The IT team suspects that the issue is due to the number of concurrent users and the design of the app. They need to improve performance without rewriting the app. What should they do first?

Accepted Answer

Redesign the app to use delegation and reduce data requests. Redesigning the app to use delegation and reduce data requests can significantly improve performance by minimizing the amount of data transferred over the network. Option A is incorrect because migrating to a model-driven app is a major rewrite, not a simple fix, and may not address the root cause. Option B is incorrect because replacing the app with a Power BI dashboard would not provide the same inventory management functionality. Option C is incorrect because increasing network bandwidth may help but is not a guarantee if the app is making inefficient queries; it is also not a first step.

Answer

Migrate the app to a model-driven app

Answer

Replace the app with a Power BI dashboard

Answer

Increase the network bandwidth at each store

Question 3

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

Question 5

A hospital uses Power BI to monitor patient wait times. The data source is an on-premises SQL Server database. To ensure real-time reporting, what should the hospital deploy?

Accepted Answer

On-premises data gateway. The on-premises data gateway (Option C) is the correct choice because it acts as a bridge between Power BI in the cloud and the on-premises SQL Server database, enabling real-time or near-real-time data refreshes for dashboards. Without this gateway, Power BI cannot directly connect to on-premises data sources, making it impossible to achieve real-time reporting from the hospital's local database.

Question 6

A non-profit organization wants to automate donation receipt emails and track donor engagement. Which Microsoft Power Platform tool should they use?

Accepted Answer

Power Automate. Power Automate is the correct tool because it enables the non-profit to create automated workflows that can trigger donation receipt emails when a new donation is recorded, and it can also update donor engagement metrics in a connected data source like Dataverse or SharePoint. This directly addresses the need for automating email notifications and tracking engagement without manual intervention.

Question 7

A retail chain uses Power Apps for an inventory management app. Employees report that the app loads slowly. What is the most likely cause?

Accepted Answer

The app uses a non-delegable query on a large data source. The most likely cause of slow loading in a Power Apps inventory management app is a non-delegable query on a large data source. When a query cannot be delegated, Power Apps retrieves all records from the data source to the client device, then filters locally, causing significant performance degradation with large datasets. This is a common issue when using functions like `Filter` with unsupported operators or columns on large tables.

Answer

The app has too many controls per screen

Answer

The app uses too many screens

Answer

The app has complex formulas in OnStart

Question 10

A retail company wants to reduce the time store managers spend on manual inventory reporting. Currently, managers use paper forms and email to submit daily stock counts, which then need to be manually entered into a central system. This process is error-prone and delays replenishment. The company wants a solution that automates data entry, provides real-time dashboards, and allows managers to submit reports from their phones without installing any software on the phones. Which combination of Microsoft Power Platform tools should the company use?

Accepted Answer

Power Apps, Power Automate, and Power BI. The scenario requires a combination of Power Apps (for mobile-friendly report submission without installing software), Power Automate (to automate data entry into the central system), and Power BI (to provide real-time dashboards). Power Apps alone cannot automate data entry or provide dashboards; Power Automate alone cannot provide a mobile input interface or dashboards; Power BI alone cannot capture data or automate workflows. Only the trio covers all requirements: mobile input, automated processing, and real-time visualization.

Answer

Power Automate only

Answer

Power Apps only

Answer

Power BI only

Question 11

A global manufacturing company uses Microsoft Power Platform to manage its equipment maintenance processes. The company has over 10,000 maintenance technicians worldwide who use a Power Apps mobile app to report equipment issues and log repairs. The app connects to a common data service (Dataverse) that stores all maintenance records. Recently, the company experienced a data breach where a malicious user exploited a vulnerability in the app to access and delete maintenance records from multiple high-value machines. The security team traced the issue to the app's permissions model: the app was using a single service account with elevated privileges to perform all data operations. The company now wants to redesign the app's security to follow the principle of least privilege while maintaining usability for technicians. The technicians need to view their assigned work orders, create new issue reports, and update the status of their own repairs, but they should not be able to delete records or access records from other regions. Which approach should the company take?

Accepted Answer

Implement row-level security in Dataverse to restrict technicians to their own records and region, assign appropriate role-based access (create, read, update, no delete), and use individual user accounts.. It applies the principle of least privilege by using individual user accounts with Dataverse role-based security and row-level security (RLS). This ensures each technician can only create, read, and update their own assigned records within their region, while explicitly denying delete permissions. This approach eliminates the shared, over-privileged service account and enforces granular data isolation.

Answer

Replace the Power Apps app with a Power Automate flow that technicians trigger via email to submit and update records.

Answer

Configure each technician's individual user account with a basic user role in Dataverse, and remove the service account.

Answer

Create a separate Power Apps app for each region, each with its own service account that has restricted permissions to that region's data.

Question 12

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

Accepted Answer

Question 15

A non-profit organization needs to collect feedback from event attendees via a form that automatically populates a SharePoint list. Which Power Platform component should they use?

Accepted Answer

Power Apps (canvas app). The requirement is to collect feedback via a form that automatically populates a SharePoint list. Power Apps (canvas app) is the correct component because it allows building custom forms that can directly write data to a SharePoint list. Power Virtual Agents is a chatbot platform, not a form builder, so it is not suitable. Power Automate can automate workflows but does not provide a user-facing form interface, and Power BI is for analytics.

Question 16

Drag and drop the steps to configure a Power Virtual Agents chatbot in the correct order.

Accepted Answer

Step 1: Create a new chatbot, Step 2: Define topics, Step 3: Add nodes to topics, Step 4: Test the chatbot, Step 5: Publish the chatbot. The correct sequence for configuring a Power Virtual Agents chatbot is: first create the bot, then define topics to handle user intents, add nodes to each topic to define the conversation flow, test the bot in the test pane to verify behavior, and finally publish the bot to make it available to users. Publishing before testing risks deploying unresolved issues.

Answer

Step 1: Create a new chatbot, Step 2: Add nodes to topics, Step 3: Define topics, Step 4: Test the chatbot, Step 5: Publish the chatbot

Question 17

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 18

Question 20

An organization is deploying Power Apps to external customers for a self-service portal. They need to ensure that customer data is isolated from internal employee data. What is the best approach?

Accepted Answer

Create separate environments for internal and external users. Creating separate environments for internal and external users provides full tenant-level isolation of customer data from employee data. Each environment in Power Platform has its own databases, security settings, and data storage, ensuring that external customers cannot access internal resources even if security roles are misconfigured.

Answer

Use Data Loss Prevention (DLP) policies in the same environment

Answer

Add external customers as B2B guests in the same environment

Answer

Use the same environment with security role-based access
