Question 3

An organization uses Power Apps to manage inventory. The app uses a SharePoint list as the data source. Users report that when two employees update the same item simultaneously, data is lost. What is the best solution?

Accepted Answer

Enable versioning on the SharePoint list and modify the app to check the last modified timestamp before update. Option D is correct because it directly addresses the root cause of data loss: concurrent updates overwriting each other. By enabling versioning on the SharePoint list, the app can retrieve the last modified timestamp before performing an update. If the timestamp has changed since the record was loaded, the app can detect a conflict and prompt the user to refresh, preventing silent overwrites. This pattern is known as optimistic concurrency control and is the standard approach for SharePoint-based Power Apps.

Answer

Switch the data source to Microsoft Dataverse

Answer

Restrict editing to one user at a time using permissions

Answer

Use Power Automate to create a flow that queues updates

Question 4

A company wants to automate the process of sending a welcome email to new employees after their HR record is created in Dataverse. Which component should be used?

Accepted Answer

Power Automate. Power Automate is the correct choice because it is designed to create automated workflows that trigger on events in Dataverse, such as the creation of a new HR record. It can then perform actions like sending a welcome email via connectors (e.g., Office 365 Outlook) without manual intervention.

Question 6

A company uses Power Automate to send approval requests. The flow is triggered when a new item is added to a SharePoint list. However, the flow fails when the item contains a large attachment. What is the most likely cause?

Accepted Answer

The attachment exceeds the maximum file size allowed by Power Automate. Power Automate imposes a maximum file size limit for attachments processed within flows. When a SharePoint list item includes a large attachment that exceeds this limit, the flow fails during the approval action because the attachment data cannot be transmitted. This is a known constraint in Power Automate, typically around 100 MB for standard connectors, and is the most direct cause of the failure described.

Answer

The flow is using the wrong trigger

Answer

The approval action is not configured for attachments

Answer

The SharePoint list is not properly configured for large files

Question 7

Accepted Answer

Power Virtual Agents. Power Virtual Agents (D) is the correct choice because it is a Power Platform component specifically designed to create conversational AI chatbots with minimal code. It allows you to build a bot that answers common IT support questions using prebuilt topics and can seamlessly escalate to a human agent via a handoff to a live chat system or Dynamics 365 Customer Service.

Question 8

Which data platform in Power Platform provides a secure, scalable database with built-in business logic and security?

Accepted Answer

Microsoft Dataverse. Microsoft Dataverse is the correct answer because it is the underlying data platform for Power Platform that provides a secure, scalable database with built-in business logic (such as business rules, workflows, and calculated fields) and role-based security.

Question 9

A Power Apps app uses a canvas and connects to multiple data sources. Users complain that the app loads slowly. What is the best practice to improve performance?

Accepted Answer

Use the 'ClearCollect' function to cache data in a collection. Option A is correct because the ClearCollect function allows you to cache data from external sources into a local collection within the app. This reduces the number of round trips to the data source during user interactions, significantly improving load and response times by minimizing network latency and data source throttling.

Answer

Add more screens to distribute the load

Answer

Increase the timeout settings

Answer

Use a single data source

Question 10

A company wants to analyze customer feedback from surveys stored in Excel and create interactive reports. Which combination of Power Platform components is best?

Accepted Answer

Power BI and Power Automate. Option C is correct because Power BI is the primary tool for creating interactive reports and dashboards from data sources like Excel, while Power Automate can be used to automate the ingestion or refresh of survey data from Excel into Power BI, enabling scheduled updates. Together, they directly address the requirement to analyze feedback and build interactive reports without needing custom app development.
