PL-900 Practice Test 17 — 15 Questions

Question 1

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. Reducing the number of data requests by using delegation and filtering can significantly improve performance. Option B is incorrect because moving to model-driven app is not a simple fix. Option C is incorrect because increasing network bandwidth may not help if the app is making inefficient queries. Option D is incorrect because Power BI is not the issue.

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 2

A small business owner wants to create a customer loyalty program. They want customers to earn points for purchases and redeem them for discounts. The owner has no coding experience and a limited budget. They need a mobile-friendly app for customers to check points and a backend to manage points and redemptions. What should they use?

Accepted Answer

Power Apps, Power Automate, and Dataverse. Power Apps (canvas app) can create a mobile-friendly app with minimal coding. Power Automate can handle point calculations and redemption logic. Dataverse provides a scalable data store. Option B is incorrect because Power Pages is for websites, not a mobile app. Option C is overkill with AI Builder. Option D is incorrect because Power BI is for analytics, not transaction processing.

Answer

Power BI, Power Automate, and Dataverse

Answer

Power Apps, AI Builder, and Dataverse

Answer

Power Pages, Power Automate, and SharePoint

Question 3

Your organization uses Power Platform environments for development, test, and production. A developer accidentally deleted a managed solution from the production environment. You need to restore the solution without affecting other components. What should you do?

Accepted Answer

Restore the environment from a backup taken before the deletion.. The correct answer is C because restoring the environment to a previous point in time using backup/restore will bring back the solution and all other components as they were. Option A is incorrect because reimporting the solution may cause data loss or conflicts. Option B is incorrect because solutions cannot be recovered from the recycle bin. Option D is incorrect because solutions cannot be recovered from the source-controlled repository automatically; you would need to deploy again, which may cause issues.

Answer

Reimport the solution from the source-controlled repository using Azure DevOps.

Answer

Use the Power Platform admin center to recover the solution from the recycle bin.

Answer

Reimport the managed solution from a backup file.

Question 4

You are a Power Platform administrator. A user reports that they are unable to share a canvas app with external users. What is the most likely cause?

Accepted Answer

The environment is not enabled for external sharing.. The correct answer is B because sharing canvas apps with external users requires that the environment is enabled for external sharing and the user has the appropriate permissions. Option A is incorrect because DLP policies do not affect sharing. Option C is incorrect because external users do not need a Power Apps license if the app is shared with them and they have appropriate access. Option D is incorrect because the environment type does not determine sharing capabilities; sandbox and production environments both support external sharing if configured.

Answer

The environment is a sandbox environment, which does not support external sharing.

Answer

The environment has a data loss prevention (DLP) policy that blocks sharing.

Answer

External users must have a Power Apps license to access the app.

Question 5

Your organization uses Power Automate to automate business processes. A flow that runs daily fails intermittently with 'HTTP 429 - Too Many Requests' errors. What should you do to resolve this issue?

Accepted Answer

Configure retry policies with exponential backoff in the flow actions.. The correct answer is C because HTTP 429 errors indicate throttling. Implementing retry policies with exponential backoff allows the flow to retry after a delay, reducing the request rate. Option A is incorrect because increasing the flow run frequency would increase the number of requests, worsening the issue. Option B is incorrect because changing the trigger type does not address throttling. Option D is incorrect because using an on-premises data gateway does not affect throttling limits.

Answer

Increase the frequency of the flow to run more often.

Answer

Change the flow trigger from a schedule to an instant trigger.

Answer

Set up an on-premises data gateway to bypass the throttling limits.

Question 6

Your organization has multiple Power Platform environments. You need to ensure that a specific connector (e.g., SQL Server) is blocked in the production environment but allowed in the development environment. What should you configure?

Accepted Answer

Create a data loss prevention (DLP) policy and assign it to the production environment.. Data loss prevention (DLP) policies in Power Platform allow administrators to classify connectors as Blocked, Business Data Only, or No Business Data Allowed. By creating a DLP policy and assigning it to the production environment, you can specifically block the SQL Server connector in that environment while leaving it available in the development environment, which is not assigned the same policy.

Answer

Set the connector's API rate limits to zero in the production environment.

Answer

Modify the connector's sharing settings in the environment.

Answer

Configure environment-level security roles to restrict connector usage.

Question 7

Your organization uses Power Virtual Agents (now Copilot Studio) for customer service. You need to ensure that the bot can access customer data from a Dataverse table that contains sensitive information. What is the best approach to secure the data?

Accepted Answer

Assign appropriate security roles and field-level security to the bot's service principal.. The correct answer is B because using Dataverse security roles and field-level security allows you to control access to the sensitive data within the bot. Option A is incorrect because DLP policies do not control data access within Dataverse. Option C is incorrect because environment-level security roles affect all users, not just the bot. Option D is incorrect because the bot's authentication settings control user identity, not data access.

Answer

Configure a data loss prevention (DLP) policy to block the bot from accessing the table.

Answer

Use the bot's authentication settings to require multi-factor authentication.

Answer

Restrict access to the environment to only the bot's service account.

Question 8

A company plans to deploy Power Apps for field service technicians. The IT department requires that all users authenticate using their corporate credentials and that access to the Power Apps environment is restricted to users from the company's tenant only. Which configuration should the administrator use?

Accepted Answer

Set the environment security group to 'Only internal users' and disable external sharing. Option D is correct because setting the environment security group to 'Only internal users' and disabling external sharing ensures that only authenticated users from the company's own Microsoft Entra ID (formerly Azure AD) tenant can access the Power Apps environment. This meets the IT requirement of restricting access to corporate credentials and the company's tenant only, preventing any external guest or user from another tenant from signing in.

Answer

Enable 'Allow users from other tenants' in environment settings

Answer

Set the environment security group to 'All users' and enable external sharing

Answer

Assign a security group that includes only specific technicians

Question 9

A Power Platform administrator needs to monitor usage and performance of environments. Which TWO actions should the administrator take? (Choose two.)

Accepted Answer

Enable audit logging in Microsoft Purview compliance portal. Option B is correct because enabling audit logging in the Microsoft Purview compliance portal captures user and admin activities across Power Platform environments, which is essential for monitoring usage and performance. Audit logs provide a detailed record of events such as environment creation, solution imports, and data access, enabling administrators to track changes and diagnose performance issues. This aligns with the requirement to monitor usage and performance, as audit data can be analyzed to identify patterns and anomalies.

Answer

Enable capacity alerts for storage

Answer

Set up Microsoft Defender XDR for Power Platform

Answer

Configure DLP policies to block high-risk connectors

Question 10

A large enterprise uses Power Platform with multiple environments. They need to enforce a policy that blocks all Canvas apps from using the 'Twitter' connector, but only in the 'Production' environment. What should the administrator do?

Accepted Answer

Create an environment-level DLP policy for the Production environment and set 'Twitter' to 'Blocked'. Option C is correct because environment-level DLP policies allow administrators to apply connector restrictions to specific environments, such as blocking the 'Twitter' connector only in 'Production' while leaving it available in other environments. This granular control is essential for enforcing governance without affecting development or testing environments.

Answer

Create a DLP policy at the tenant level and set the 'Twitter' connector to 'Blocked'

Answer

Disable the 'Twitter' connector in the Power Platform admin center for the Production environment

Answer

Use the 'Set Connector' API to disable the connector for the Production environment

Question 11

A company wants to allow external partners to access a Power Apps portal without requiring a Microsoft Entra ID account. What should the administrator configure?

Accepted Answer

Configure the portal to use local authentication with username and password. Option B is correct because Power Apps portals support local authentication, which allows external users to sign up and sign in using a username and password without requiring a Microsoft Entra ID account. This is the appropriate method when the goal is to grant access to partners who do not have or need Microsoft Entra ID credentials.

Answer

Create Microsoft Entra ID guest accounts for each partner

Answer

Share the Power Apps app directly with the partners

Answer

Enable Microsoft Entra ID B2B collaboration and invite partners

Question 12

Refer to the exhibit. A Power Platform administrator applies this DLP policy to the default environment. What is the result?

Accepted Answer

Microsoft Teams and Twitter connectors are blocked in the default environment. The exhibit shows a Data Loss Prevention (DLP) policy configured with Microsoft Teams and Twitter connectors in the 'Blocked' group. Since this policy is applied to the default environment, only those two connectors are blocked in that environment. All other connectors remain in the 'Allowed' group by default, so they are permitted. Therefore, the correct result is that Microsoft Teams and Twitter connectors are blocked in the default environment.

Answer

All connectors are allowed

Answer

All connectors are blocked

Answer

The policy applies to all environments

Question 13

A user wants to create a simple app to track personal expenses using an Excel file stored in OneDrive. Which Power Apps approach should they use?

Accepted Answer

Create a canvas app from the Excel file. A canvas app can be created directly from an Excel file stored in OneDrive using the Power Apps 'Start from data' option. This generates a three-screen app (browse, detail, edit) that connects to the Excel table via the OneDrive for Business connector, making it ideal for simple personal expense tracking without requiring Dataverse or custom development.

Answer

Use Power Pages to display the Excel file

Answer

Create a model-driven app using Dataverse

Answer

Use Power Automate to create a mobile app

Question 14

A company wants to grant a user the ability to manage environments in Power Platform, including creating and deleting environments, but without full tenant admin access. Which role should be assigned?

Accepted Answer

Environment Admin. Option A is correct because the Environment Admin role allows managing environments within the tenant. Option B is wrong because System Administrator is a Dataverse role, not for environment management. Option C is wrong because Power Platform Admin has broader tenant-level permissions. Option D is wrong because Global Admin has full access to all services.

Answer

Global Administrator

Answer

Power Platform Administrator

Answer

System Administrator

Question 15

The exhibit shows a DLP policy configuration for a Power Platform environment. Which connector is allowed for business use?

Accepted Answer

SharePoint. SharePoint is classified as 'Business' in the DLP policy because it is a Microsoft-owned enterprise service that supports data loss prevention (DLP) actions like blocking, monitoring, or restricting data flow. The exhibit shows SharePoint under the 'Business' data group, meaning it is allowed for business use without triggering policy violations. In contrast, Outlook, Twitter, and Facebook are placed in the 'Non-Business' group, which blocks their connectors from being used in apps and flows within this environment.

Answer

Outlook

Answer

Twitter

Answer

Facebook
