PL-900 Practice Test 6 — 10 Questions

Question 1

Match each connector type in Power Automate to its description.

Question 2

Match each Power Virtual Agents feature to its purpose.

Question 3

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 4

Which TWO components are part of the Microsoft Power Platform? (Choose two.)

Accepted Answer

Power Virtual Agents. Power Virtual Agents (A) is a component of the Microsoft Power Platform that enables users to create intelligent chatbots using a no-code graphical interface, without requiring developers or data scientists. It integrates with Power Automate and Power Apps to extend bot capabilities, making it a core part of the platform's low-code AI offerings.

Question 6

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. Option C is correct because 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 7

A sales team uses a Canvas app to track leads. Users report that the app loads slowly when accessing on mobile devices. Which component should be optimized to improve performance?

Accepted Answer

Optimize data source connections and queries. Optimizing data source connections and queries directly reduces the amount of data transferred and the number of round trips between the Canvas app and its data source (e.g., Dataverse, SharePoint, SQL). On mobile devices, network latency and bandwidth are often constrained, so inefficient queries (e.g., loading all records instead of using filters) cause significant slowdowns. This is the primary performance lever for Canvas apps, as per Microsoft's guidance on app optimization.

Answer

Update the app version number

Answer

Increase the app icon size

Answer

Change the app's background color

Question 8

A retail company uses Power Apps to build a mobile app for store managers to approve discount requests. The app must work offline and sync when connected. Which type of app should the developer choose?

Accepted Answer

Canvas app. Canvas apps are the correct choice because they support offline capability by leveraging the Power Apps offline sync feature, which allows data to be cached locally on the device and synchronized with the data source (e.g., Dataverse or SharePoint) when connectivity is restored. This makes them ideal for mobile scenarios like store managers approving discount requests in areas with intermittent connectivity.

Answer

Portal

Answer

Model-driven app

Answer

Power Automate

Question 9

A developer is trying to create a business process flow (BPF) for the 'Opportunity' table in a model-driven app. When activating the BPF, the developer receives the error shown in the exhibit. What is the most likely cause?

Accepted Answer

The BPF is trying to use a table that is not enabled for business process flows.. The error shown in the exhibit indicates that the business process flow (BPF) references a table that is not enabled for business process flows. In Power Apps, only tables that have the 'Business process flows' option enabled in their table settings can be used as the primary entity for a BPF. The 'Opportunity' table is a standard table that is enabled by default, but if it has been disabled or the BPF is referencing a custom table that lacks this setting, activation will fail with this error. Option C correctly identifies this root cause.

Answer

The developer does not have sufficient security role permissions to activate BPFs.

Answer

The BPF has no stages defined.

Answer

The Opportunity table does not exist.

Question 10

A sales manager wants to create a dashboard that shows sales by region and product category. The data is stored in an Excel file that is updated weekly. What is the most efficient way to ensure the dashboard reflects the latest data?

Accepted Answer

Publish the report from Power BI Desktop and schedule a daily data refresh in Power BI service. Option A is correct because it separates the report creation (in Power BI Desktop) from the data refresh schedule (in the Power BI service). By publishing the report once and configuring a daily scheduled refresh, the dashboard automatically reflects the latest data from the Excel file without manual intervention, which is the most efficient approach for weekly updates.

Answer

Use Power BI Desktop to connect to the Excel file and publish a new report weekly

Answer

Use Power Query to merge data from the Excel file and create a composite model

Answer

Upload the Excel file to the Power BI service each week
