PL-900 Practice Test 27 — 15 Questions

Question 1

An organization has a canvas app that uses a SharePoint list as its data source. Users report that the app loads slowly and sometimes times out. The developer needs to improve performance. Which approach should the developer take?

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

Accepted Answer

Use delegable queries to filter data at the source. Using delegable queries allows the data source to filter data before sending it to the app, reducing the amount of data transferred and improving performance. Option A is wrong because increasing timeouts does not address the root cause of slow loading. Option B is wrong because migrating to SQL Server is an unnecessary and costly change; the issue can be resolved within the current data source by using delegation. Option C is wrong because splitting into multiple screens does not reduce the data load per screen if queries are not delegable.

Answer

Increase the timeout setting in the app settings

Answer

Migrate the data source to SQL Server to improve performance

Answer

Split the app into multiple screens to reduce load per screen

Question 2

Which THREE actions are available in Power Automate to handle errors and exceptions?

Accepted Answer

Use a 'Scope' action to group actions and configure error handling. Power Automate provides several built-in features for handling errors and exceptions. Option A is correct: a 'Scope' action groups actions, and you can configure error handling on the scope. Options B and E are correct: the 'Configure run after' option (or 'Run after' settings) on an action allows you to define what happens on failure, timeout, or skip, making it a direct error-handling action. Option C is incorrect because enabling a retry policy is a configuration setting on an action, not a distinct error-handling action like Scope or Run after. Option D is incorrect as the 'if' function is an expression, not an action.

Answer

Enable 'Retry policy' on an action to automatically retry on failure

Answer

Use the 'if' function in expressions to check for errors

Question 3

A company uses Power Virtual Agents (now Copilot Studio) to build a customer service chatbot. The bot needs to securely escalate to a live agent when it cannot resolve the issue. The escalation must pass the conversation context to the agent. What should the bot use?

Accepted Answer

Transfer conversation action. The 'Transfer conversation' action in Copilot Studio is designed to escalate the conversation to a live agent while passing the full conversation context, making it the correct choice for secure escalation with context.

Answer

HTTP request to a webhook

Answer

Power Automate flow trigger

Answer

Custom connector for the live agent system

Question 4

A Power Platform administrator wants to delegate the responsibility of managing environments to regional leads without granting them full admin privileges. Which role should the administrator assign?

Accepted Answer

Environment Admin role.. The Environment Admin role allows a user to manage all aspects of a specific environment, including security and settings, without tenant-wide privileges. Option B, Dynamics 365 Administrator, is a broader role that includes Dynamics 365 apps and is not specific to Power Platform environment management. Option C, System Customizer, only allows customization of system settings and forms, not full environment management. Option D, Power Platform Administrator, is a tenant-wide role that grants administrative access to all environments, which is more than what is needed for delegation to regional leads.

Answer

Dynamics 365 Administrator role.

Answer

System Customizer role.

Answer

Power Platform Administrator role.

Question 5

You are a Power Platform administrator for a non-profit organization. The organization has a single environment used by volunteers and staff. A new volunteer needs to be able to run a specific Power App that manages event registrations, but should not be able to modify the app or access any other resources in the environment. The volunteer has a valid Power Apps license. You need to provide the volunteer with the minimum permissions necessary. What should you do?

Accepted Answer

Share the app directly with the volunteer. To share the app directly with the volunteer. When you share an app in Power Apps, you can grant the volunteer the 'User' permission, which allows them to run the app but not modify it. This satisfies the requirement of minimum permissions. Option B is incorrect because creating a new environment is unnecessary and adds complexity. Option C is incorrect because the Environment Maker role allows the volunteer to create and edit resources, which exceeds the needed permissions. Option D is incorrect because the System Administrator role provides full control over the environment, which is too permissive.

Answer

Create a new environment and add the volunteer there

Answer

Assign the volunteer the Environment Maker role and share the app

Answer

Add the volunteer to the System Administrator role

Question 6

Refer to the exhibit.

{
  "name": "Environment Usage Report",
  "type": "Power BI report",
  "dataset": {
    "name": "Power Platform Admin View",
    "tables": [
      {
        "name": "Environments",
        "columns": [
          { "name": "EnvironmentName", "dataType": "string" },
          { "name": "TotalActiveUsers", "dataType": "int" },
          { "name": "TotalAppUsage", "dataType": "int" },
          { "name": "TotalFlowRuns", "dataType": "int" }
        ]
      }
    ]
  }
}

An admin runs a report to see total active users per environment. The report shows zero active users for a production environment that is actively used. What is the most likely reason?

Accepted Answer

The environment is not included in the Power Platform Admin View dataset. The Power Platform Admin View dataset may not include all environments, especially if the production environment is not designated as an admin-managed environment or if it is a default environment not added to the Admin View. This can result in zero active users reported. Option B is incorrect because the report uses a Power BI report with a dataset, not a canvas app connector. Option C is incorrect because the TotalActiveUsers column is present in the dataset as shown in the exhibit. Option D is incorrect because the admin would typically have permission to view the dataset if they can run the report, and the issue is about data inclusion, not permissions.

Answer

The report uses a canvas app connector that is blocked

Answer

The TotalActiveUsers column is missing from the dataset

Answer

The admin does not have permission to view the dataset

Question 7

Your company wants to analyze sales data from multiple sources and create interactive dashboards. The solution must be cloud-based and require minimal IT support. Which Power Platform component should you use?

Accepted Answer

Power BI. Power BI is the correct choice because it is a cloud-based business analytics service that enables you to connect to multiple data sources, transform and model the data, and create interactive dashboards and reports. It requires minimal IT support through its self-service capabilities, allowing business analysts to build visualizations without deep technical expertise.

Answer

Power Apps

Answer

Power Automate

Answer

Power Virtual Agents

Question 8

A government agency uses Power Platform with strict compliance requirements. They need to retain all audit logs of user activities within Power Platform for at least 7 years. The agency uses Microsoft Purview for compliance and Microsoft Sentinel for security monitoring. The admin needs to ensure that all Power Platform audit events are captured and retained for the required period. What should the admin do?

Accepted Answer

Configure a retention policy in Microsoft Purview for the Power Platform audit logs.. Power Platform audit logs are stored in the Microsoft 365 unified audit log. Microsoft Purview allows configuring retention policies for these logs to meet compliance requirements. Option C is correct because it directly addresses the need to retain logs for 7 years via a Purview retention policy. Options A, B, and D are insufficient or misaligned: A (export to Azure Blob Storage) is an extra step and not the native retention mechanism; B (Microsoft Sentinel) is for security monitoring, not primary retention; D (enabling audit logging) is necessary but does not set the retention duration.

Answer

Export audit logs to Azure Blob Storage and set a retention policy there.

Answer

Use Microsoft Sentinel to store and retain the logs for 7 years.

Answer

Enable audit logging in each Power Platform environment's settings.

Question 9

The exhibit shows a JSON snippet used to create a Power Platform environment via the Power Platform API. The administrator runs the script but the environment is created with the default language and currency instead of the specified values. What is the most likely reason?

Accepted Answer

The JSON syntax is invalid because of the empty securityGroupId.. The JSON snippet uses an empty GUID for 'securityGroupId' (all zeros). In the Power Platform API, an empty or invalid GUID in this field can cause the entire Dataverse settings block to be ignored, resulting in the environment being created with default language and currency. Option A correctly identifies this syntax issue. Options B, C, and D are incorrect because the API version, environment name, and location are valid.

Answer

The API version used does not support specifying language and currency.

Answer

The environment name "ContosoSales" is already in use.

Answer

The location "eastus" is not a valid Azure region for Power Platform.

Question 10

Which TWO actions can a Power Platform admin perform in the Power Platform admin center to manage environments? (Choose two.)

Accepted Answer

Create and delete environments.. Options B and C are correct. A Power Platform admin can create and delete environments and manage environment security roles in the Power Platform admin center. Option A is incorrect because modifying Dataverse table schemas is done in the Power Apps maker portal, not the admin center. Option D is incorrect because assigning Power Apps licenses to users is performed in the Microsoft 365 admin center. Option E is incorrect because creating Microsoft Entra ID security groups is done in the Microsoft Entra admin center.

Answer

Modify Dataverse table schemas.

Answer

Assign Power Apps licenses to users.

Answer

Create Microsoft Entra ID security groups.

Question 11

A company is migrating a complex Power Apps solution from a development environment to production. The solution includes custom connectors, flows, and Dataverse tables. Which THREE steps should the administrator take to ensure a successful migration?

Accepted Answer

Test the solution in a staging environment first. To ensure a successful migration, the administrator should test the solution in a staging environment first (A) to validate functionality, export it as a managed solution (C) to maintain component relationships and support future upgrades, and run the solution checker (E) to identify and fix issues before migration. Deleting the development environment after export (B) is risky because it removes the source before the migration is verified. Manually recreating the solution in production (D) is error-prone and not recommended.

Answer

Delete the development environment after export

Answer

Manually recreate the solution in production

Question 12

An organization wants to analyze customer sentiment from social media data and create interactive dashboards. Which combination of Power Platform tools should they use?

Accepted Answer

Power BI and AI Builder. Power BI can connect to data sources and create dashboards, while AI Builder can analyze sentiment. Power Automate is for workflows, and Power Apps for apps.

Answer

Power BI and Power Apps

Answer

Power Automate and Power Virtual Agents

Answer

Power Apps and Power Automate

Question 13

A Power App uses a Patch function to update a Dataverse table. The app runs into delegation warnings for large datasets. Which approach best resolves delegation warnings while maintaining functionality?

Accepted Answer

Use delegable functions such as Filter and LookUp to retrieve only necessary records before performing updates. Using delegable functions like Filter and LookUp allows the app to process only the necessary subset of records from Dataverse, avoiding delegation warnings by keeping data operations within the server's capacity. Option A is wrong because increasing the data row limit only changes the number of records fetched, but does not resolve delegation warnings; it may even exacerbate performance issues. Option B is wrong because switching to SharePoint does not inherently fix delegation problems—SharePoint has different delegation limits and may still trigger warnings. Option C is wrong because avoiding delegable functions would likely make delegation warnings worse, as non-delegable functions force the app to load all data locally.

Answer

Increase the data row limit in the app settings

Answer

Switch the data source to SharePoint for better delegation support

Answer

Avoid using delegable functions to reduce complexity

Question 14

A company needs to build a Power App that allows employees to submit IT support tickets. The app must be available from both Microsoft Teams and the web, and must use Dataverse for storage. Which type of app should be used?

Accepted Answer

Model-driven app. Model-driven apps are the correct choice because they are designed to work with Dataverse and can be embedded in Microsoft Teams and accessed via the web. They provide a structured, data-centric interface that aligns well with IT support ticket scenarios. Option A is incorrect because Power Pages sites are for external-facing websites, not internal apps. Option B is incorrect because although canvas apps can connect to Dataverse, they are not primarily optimized for Dataverse-driven, structured data apps and may require more custom development. Option C is incorrect because Power Automate is a workflow automation tool, not an app platform.

Answer

Power Pages site

Answer

Canvas app with Dataverse connector

Answer

Power Automate portal

Question 15

A Power Apps canvas app uses a SharePoint list as a data source. Users report that the app is slow when loading data. The list has 10,000 items. Which optimization should you recommend?

Accepted Answer

Use delegable filters like Filter() with indexed columns to limit data retrieved. Delegable filters such as Filter() with indexed columns allow Power Apps to push filtering to the data source (SharePoint), reducing the amount of data retrieved and improving performance. Option A is incorrect because reducing columns has minimal impact on the amount of data loaded, and delegable queries are more effective. Option B is incorrect because increasing the data row limit for non-delegable queries only affects the number of records displayed, not the data retrieved from SharePoint; the query still fetches all 10,000 items. Option C is incorrect because moving to SQL and using Power Automate introduces additional complexity and potential latency, and is not the most direct optimization for a SharePoint data source.

Answer

Reduce the number of columns in the SharePoint list

Answer

Increase the data row limit for non-delegable queries to 2000

Answer

Move the data to a SQL database and connect via Power Automate
