PL-900 Describe the business value of Microsoft Power Platform Practice Test 3 — 15 Questions

Question 1

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 2

Which THREE components are part of the Microsoft Power Platform? (Select THREE)

Accepted Answer

Power Apps. Power Apps (A) is a core component of the Microsoft Power Platform, providing a low-code/no-code canvas and model-driven app development environment for building custom business applications. Power Automate (B) is also a core component, delivering workflow and robotic process automation (RPA) capabilities to automate repetitive tasks and integrate services via connectors. Power BI (C) is the third core component, offering business analytics and interactive data visualization to turn data into actionable insights. These three, along with Power Virtual Agents and Power Pages, are often grouped as the platform's key services, but the question's marked correct answers are specifically A, B, and C. Power Virtual Agents (D) and Power Pages (E) are not marked correct here, so they do not belong to the set of three components this question expects.

Answer

Power Virtual Agents

Answer

Power Pages

Question 3

Your organization uses Microsoft Power Platform to manage customer support tickets. The current process: when a ticket is created in Dataverse, a Power Automate flow sends an email to the support team. The team then updates the ticket status manually in a Power Apps canvas app. However, the team often forgets to update the status, leading to delayed responses. The manager wants an automated solution that sends a reminder if the status is not changed within 24 hours. Additionally, if the status is not changed within 48 hours, the ticket should be escalated to the manager. You need to design a solution using Power Automate and Power Apps. Which approach should you take?

Accepted Answer

Create two scheduled Power Automate flows: one runs daily to check tickets older than 24 hours and send reminder; another runs daily to check tickets older than 48 hours and escalate.. It uses two separate scheduled flows that run daily to check ticket ages and perform actions based on conditions. This approach ensures automatic reminders after 24 hours and escalation after 48 hours without relying on user action. Option A is wrong because the Power Apps notify function would require the app to be open and doesn't provide recurring checks. Option C is wrong because an hourly recurrence may waste resources and create duplicate actions; a daily schedule is more appropriate. Option D is wrong because a single flow triggered on creation with delays would only run once per ticket, not continuously check for updates.

Answer

Modify the Power Apps app to include a reminder notification using the notify function after 24 hours.

Answer

Create one Power Automate flow with a recurrence trigger every hour. Check tickets older than 24 hours and send reminder; if also older than 48 hours, escalate. Add condition to avoid duplicate actions.

Answer

Create a single Power Automate flow triggered when a ticket is created. Add a 24-hour delay then check status; if not updated, send reminder and wait another 24 hours then escalate.

Question 4

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?

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

Accepted Answer

Power Apps portals. Power Apps portals (now part of Power Pages) allow external users, such as suppliers, to access data through a low-code, authenticated website without requiring a Power Apps license or internal network access. This enables suppliers to view stock levels via a browser-based interface while preventing any modification, as permissions can be set to read-only. Canvas apps, by contrast, are designed for internal users and require a license or guest access in Microsoft Entra ID, making portals the correct choice for external, unauthenticated or lightly authenticated scenarios.

Answer

Power BI dashboard

Answer

Canvas app

Answer

Power Automate

Question 5

A financial services firm uses Microsoft Power Platform to automate loan approval processes. They have a Power Automate flow that triggers when a new loan application is submitted in SharePoint, then uses AI Builder to extract key fields from uploaded documents, and finally updates a Dataverse table. The compliance team requires that all automated decisions be auditable and explainable. Which feature should the firm use to meet this requirement?

Accepted Answer

Enable Power Automate audit logging in the environment. Power Automate audit logging captures detailed records of flow runs, including which automated decisions were made, when, and by which flow. This provides the compliance team with a verifiable, immutable audit trail that meets regulatory requirements for explainability and accountability. Unlike AI Builder's explainability mode, which only offers model-level insights, audit logging records the full execution context of the flow.

Answer

Enable AI Builder explainability mode

Answer

Store all extracted data in a separate SharePoint list with versioning

Answer

Use Copilot Studio to create a chatbot that logs decisions

Question 6

A manufacturing company uses Power Automate to approve purchase orders. The flow includes a condition that if the order amount exceeds $10,000, it requires approval from the finance manager; otherwise, it is auto-approved. Recently, the finance manager left the company, and the flow fails. The IT admin needs to update the flow to use a new finance manager. What is the recommended way to maintain this configuration?

Accepted Answer

Use an environment variable for the approver email. Environment variables in Power Automate allow you to store configuration values, such as an approver's email, separately from the flow logic. When the finance manager changes, you only need to update the environment variable value once, and all flows referencing it automatically use the new value. This decouples configuration from code, making maintenance easier and reducing the risk of errors.

Answer

Create a SharePoint list with the approver email and look it up in the flow

Answer

Edit the flow to hardcode the new finance manager's email

Answer

Use dynamic content from a Dataverse table

Question 7

A global organization uses Power Platform to manage IT support tickets. They have the following requirements: 1) Tickets must be routed to the appropriate team based on category. 2) The routing logic must be easy to update by non-developers. 3) All ticket data must be stored in a secure, auditable data source. Which THREE Power Platform components should they use?

Accepted Answer

Power Automate. Power Automate (B) is correct because it provides the workflow engine that can automatically route tickets to the appropriate team based on category, using triggers and conditions that non-developers can edit in the visual designer. Business rules in Dataverse (D) are correct because they let non-developers define and easily update routing logic (such as setting or validating the assigned team based on category) declaratively, without writing code. Dataverse (E) is correct because it is the secure, role-based, auditable data store for Power Platform, providing built-in security roles, auditing, and compliance features for all ticket data. Copilot Studio (A) is not appropriate here because it is for building conversational AI agents, not for routing logic or data storage. Power Apps (C) is a UI layer for building the ticket entry app, but it does not by itself provide the routing logic or the secure auditable data source required.

Answer

Copilot Studio

Answer

Power Apps

Question 8

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

Answer

Power Automate flow

Answer

Power BI app

Question 9

You are the Power Platform administrator for a large enterprise with multiple departments. The HR department uses a Power Apps canvas app to manage employee onboarding. The app is connected to Dataverse and includes a flow that sends a welcome email via Power Automate. Recently, the IT security team mandated that all Power Platform solutions must use Microsoft Entra ID for authentication and that sensitive data (e.g., social security numbers) must be encrypted at rest. The HR app currently uses Dataverse's default encryption. Additionally, the HR team wants to extend the app to external contractors who do not have Microsoft Entra ID accounts. They need to be able to submit their personal information through a secure web form. You need to design a solution that meets security requirements and allows external access. What should you do?

Accepted Answer

Enable customer-managed encryption key (CMEK) for Dataverse, and create a Power Pages site with Microsoft Entra External ID authentication for external contractors.. It addresses both security requirements: customer-managed encryption key (CMEK) for Dataverse ensures sensitive data like social security numbers is encrypted at rest with a key controlled by the enterprise, meeting the IT security mandate. Additionally, creating a Power Pages site with Microsoft Entra External ID authentication allows external contractors without Microsoft Entra ID accounts to authenticate via social or email-based identities, enabling secure submission of personal information through a web form while maintaining compliance.

Answer

Create a SharePoint list for external contractors to submit data, and use Power Automate to send emails.

Answer

Use Power Apps portals with Microsoft Entra ID B2B collaboration for external contractors, and leave encryption as default.

Answer

Implement a Power Automate flow to collect data via Microsoft Forms, and store results in Dataverse with default encryption.

Question 10

A healthcare provider wants to digitize patient intake forms. The solution must comply with HIPAA and allow patients to fill forms on their own devices. The data should be stored securely, and staff should receive notifications when a form is completed. Which approach using Power Platform should they take?

Accepted Answer

Use Power Pages for the patient portal, Dataverse for storage, and Power Automate for notifications. Power Pages provides a secure, externally-facing portal where patients can fill forms on their own devices, Dataverse (the underlying data platform) supports HIPAA-compliant storage with encryption and auditing, and Power Automate can trigger notifications to staff when a form is completed. This combination meets all requirements: patient self-service, secure storage, and automated alerts.

Answer

Build a Power Apps canvas app for patients and use Power Automate for notifications

Answer

Use Power BI dashboards for patients to submit data and Power Automate for notifications

Answer

Use Power Automate with AI Builder to process forms and store results in SharePoint

Question 11

A multinational corporation uses Power Platform extensively. They have multiple Dataverse environments for development, test, and production. The security team requires that all solution changes be tracked, and deployment must follow a controlled process with approval gates. They also need to ensure that sensitive data in production cannot be exported to development. Which combination of Power Platform capabilities should they implement?

Accepted Answer

Managed Environments, Solution History, and DLP policies. Managed Environments provide governance controls like sharing limits, solution checker enforcement, and maker welcome content, while Solution History tracks all solution changes for auditing. DLP policies prevent sensitive data from being exported from production to development by restricting connectors and data flow between environments. Together, these three capabilities satisfy the requirements for controlled deployment, change tracking, and data loss prevention.

Answer

Power BI, Managed Environments, and Solution History

Answer

Solution History, AI Builder, and DLP policies

Answer

Managed Environments, Copilot Studio, and DLP policies

Question 12

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 13

A university wants to create a system for students to register for extracurricular activities. The system should allow students to view available activities, sign up, and receive confirmation emails. Staff should be able to manage activities and view attendance reports. The university has Power Platform licenses but limited IT resources. Which solution should they implement?

Accepted Answer

Power Apps (model-driven) for staff, Power Apps (canvas) for students, Power Automate for emails, and Power BI for reports. It uses the right tool for each job: a model-driven Power App gives staff the structured, data-centric interface needed to manage activities and view attendance reports, while a canvas Power App provides students with a flexible, user-friendly sign-up experience. Power Automate handles the confirmation emails, and Power BI delivers the attendance reports, all within the university's existing Power Platform licenses and without requiring extensive IT resources.

Answer

AI Builder and Power Automate to process registrations

Answer

Power Automate for everything, with SharePoint lists for data storage

Answer

Power Pages for students, Power Automate for emails, and Power BI for reports

Question 14

A logistics company uses Power Platform to track shipments. They have a Power Apps app for drivers to update delivery status, and Power Automate flows to notify customers. Recently, drivers reported that the app sometimes fails to sync data when they are in areas with poor connectivity. The company needs a solution that allows offline data entry and automatic sync when connectivity is restored. What should they do?

Accepted Answer

Enable offline capability in the Power Apps canvas app and use Dataverse for offline data storage. Power Apps canvas apps support offline capability when connected to Dataverse, which can store data locally on the device and automatically synchronize with the server when connectivity is restored. This directly addresses the drivers' need for offline data entry and sync in poor connectivity areas.

Answer

Use AI Builder to predict connectivity issues and queue data

Answer

Migrate the app to a model-driven app with offline sync

Answer

Replace the app with a Power BI dashboard that refreshes periodically

Question 15

A logistics company's finance department receives hundreds of PDF invoices each week as email attachments. Staff currently open each PDF, retype the vendor name, invoice number, and total into an Excel workbook, then route the file to the correct approver. Management wants to eliminate the retyping and ensure consistent field extraction without hiring developers. Which Power Platform capability best addresses the data extraction step?

Accepted Answer

AI Builder prebuilt invoice processing model used from Power Automate. The finance team needs automated, consistent extraction of specific fields from PDF invoices. AI Builder's prebuilt invoice processing model is trained for exactly this document type and returns structured vendor, invoice number, and total values. Because it can be called from Power Automate, the same flow can then route the invoice to the correct approver, delivering both the extraction and the downstream routing the company described.

Answer

Power BI dashboards connected to the Excel workbook

Answer

A Power Apps canvas app with a gallery of invoice attachments

Answer

Power Virtual Agents bot that asks vendors to resubmit invoice details
