PL-900 Practice Test 25 — 15 Questions

Question 1

A company has deployed a custom copilot built with Microsoft Copilot Studio to support the sales team. The copilot uses a SharePoint site containing product documentation and a public website for industry news as knowledge sources. The copilot is configured with anonymous access and is published to a demo page. Recently, the sales team has been using the copilot to answer customer questions, but they report that the copilot sometimes provides incorrect product specifications and cites sources that are not related to the company's products. The administrator needs to improve the accuracy and relevance of the copilot's responses while maintaining the ability to answer questions about industry news. What should the administrator do first?

Accepted Answer

Remove the public website as a knowledge source and add a more specific industry news source. The core issue is that the public website knowledge source is introducing irrelevant or incorrect information into the copilot's responses. By removing it and adding a more specific industry news source, the administrator directly addresses the source of inaccuracy while preserving the ability to answer industry news questions. This aligns with the principle that knowledge source quality directly impacts generative AI response relevance in Microsoft Copilot Studio.

Answer

Enable Microsoft Entra ID authentication to restrict access

Answer

Turn off Generative AI and use only manual topics

Answer

Add additional SharePoint sites with product specifications

Question 2

An administrator needs to ensure that only users from a specific Microsoft Entra ID group can access a Power Platform environment. What should the administrator configure?

Accepted Answer

Assign a security group to the environment in the Power Platform admin center. Assigning a security group to an environment in the Power Platform admin center restricts access to only members of that Microsoft Entra ID group. This is the standard method for controlling user access to a Power Platform environment, ensuring that only authorized users can interact with its resources.

Answer

Disable the 'Create personal productivity environments' setting

Answer

Set environment capacity limits

Answer

Configure a data loss prevention (DLP) policy

Question 3

A company has deployed a custom copilot built with Microsoft Copilot Studio. Users report that the copilot sometimes provides outdated information. The knowledge sources are SharePoint sites and public websites. The copilot uses Generative AI to formulate answers. What should the administrator do to improve the accuracy of the copilot's responses?

Accepted Answer

Refresh the knowledge sources periodically. The copilot's knowledge sources (SharePoint sites and public websites) are not automatically refreshed in real time. By periodically refreshing these sources, the administrator ensures the copilot's generative AI has access to the most current content, directly addressing the issue of outdated information.

Answer

Enable the 'Show citations' option

Answer

Reduce the number of topics

Answer

Turn off Generative AI for responses

Question 4

A company wants to build a public-facing website that allows external users to register and submit support tickets. The site must integrate with Dataverse and support custom workflows. Which Power Platform component should they use?

Accepted Answer

Power Pages. Power Pages is designed for external-facing websites with low-code capabilities and seamless Dataverse integration.

Answer

Power Virtual Agents

Answer

Power Automate

Answer

Power Apps portal

Question 5

A company wants to create a mobile app for field technicians to log service calls. The app will connect to an existing SQL database. Which type of Power App should they build?

Accepted Answer

Canvas app. A canvas app is the right choice because it lets the maker design a custom, task-focused UI from scratch and connect directly to an existing SQL database via the SQL Server connector (or through a data gateway for on-premises SQL). Field technicians need a tailored mobile experience for logging service calls, which is exactly the canvas app design pattern. Model-driven apps require Dataverse as the data platform and are not designed to bind directly to an external SQL database as their primary source.

Answer

Power Automate flow

Answer

Model-driven app

Answer

Power Pages

Question 6

An organization wants to enforce that all Power Apps in their tenant use only approved connectors and cannot connect to unmanaged data sources. What should they configure?

Accepted Answer

Data Loss Prevention (DLP) policies in the Power Platform admin center. Data Loss Prevention (DLP) policies in the Power Platform admin center are the correct tool to enforce which connectors can be used across Power Apps, Power Automate, and Power Virtual Agents. By classifying connectors as 'Business' or 'Blocked,' administrators can prevent apps from connecting to unmanaged or non-approved data sources, ensuring compliance with organizational data governance requirements.

Answer

Question 7

Which TWO of the following are key benefits of using Microsoft Dataverse? (Choose two.)

Accepted Answer

Business logic such as calculated columns and business rules. Option A is correct because Microsoft Dataverse natively supports declarative business logic such as calculated columns, rollup columns, and business rules, which run server-side without custom code. Option B is correct because Dataverse provides built-in security at the row and column level through role-based access control (RBAC), business units, teams, and field-level security. Option C is not a key Dataverse benefit because Dataverse is designed for structured/tabular business data, while unstructured content like videos is typically stored in SharePoint or Azure Blob Storage. Option D is incorrect because embedding in Microsoft Teams requires configuration/integration (e.g., via Power Apps or Dataverse for Teams), not automatic direct embedding. Option E is incorrect because real-time analytics dashboards are provided by Power BI, not as a core Dataverse benefit.

Answer

Ability to store unstructured data like videos

Answer

Direct embedding in Microsoft Teams without any integration

Answer

Real-time analytics dashboards

Question 8

A company wants to use Microsoft Copilot Studio to build a chatbot that helps employees reset their passwords. Which TWO components are required? (Choose two.)

Accepted Answer

Power Automate to connect to the password reset system. Power Automate is required to create a flow that connects the chatbot to the password reset system, enabling automated execution of the reset process. Without this integration, the chatbot cannot perform the backend action of resetting the password.

Answer

Power Virtual Agents (classic)

Answer

Power Apps to create the user interface

Answer

AI Builder to process natural language

Question 9

A company uses a model-driven app to manage support tickets. Users want to automate the creation of a follow-up task when a ticket is resolved. Which component should be used?

Accepted Answer

Power Automate flow. Power Automate can trigger on record changes (e.g., status change to resolved) to automatically create a follow-up task. Option B is wrong because Microsoft Copilot Studio is for building chatbots, not for task automation. Option C is wrong because a custom Power Apps page would require manual interaction, not automation. Option D is wrong because Business Rules are limited to simple form logic and cannot create records.

Answer

Microsoft Copilot Studio

Answer

Custom Power Apps page

Answer

Business Rule

Question 10

A non-profit organization wants to create a public donation page using Power Pages. Donors should be able to enter their information and submit without creating an account. What type of authentication should be configured for the donation page?

Accepted Answer

Anonymous. For a public donation page where donors should submit information without creating an account, anonymous authentication is required. Power Pages supports anonymous access, allowing unauthenticated users to view and interact with the site. This is the only option that permits access without any identity provider.

Answer

SAML 2.0

Answer

Microsoft Entra ID

Answer

OpenID Connect

Question 11

A user reports they cannot create a new Power Apps app in the default environment. They have a Power Apps license. What is the most likely cause?

Accepted Answer

The user has not been assigned the Environment Maker security role for the default environment.. The most likely cause is that the user has not been assigned the Environment Maker security role for the default environment. Even with a Power Apps license, a user must be explicitly granted the Environment Maker role in a specific environment (including the default environment) to create apps. Without this role, the user can only run apps, not create or edit them.

Answer

A data loss prevention (DLP) policy is blocking app creation.

Answer

The environment has reached its maximum number of apps.

Answer

The user does not have a Power Apps license.

Question 12

A healthcare organization is deploying Power Apps for patient intake. They must ensure that the app complies with HIPAA regulations. Which feature should they use to protect patient data at rest?

Accepted Answer

Enable Customer Managed Key (CMK) for the Power Platform environment.. Customer Managed Key (CMK) allows the healthcare organization to control the encryption key used to protect data at rest in their Power Platform environment. This ensures that even Microsoft cannot access the underlying data without the organization's key, which is a critical requirement for HIPAA compliance regarding data encryption at rest.

Answer

Require multi-factor authentication (MFA) for app users.

Answer

Enable audit logging in the Power Platform admin center.

Answer

Create a Data Loss Prevention (DLP) policy to restrict connectors.

Question 14

Which THREE of the following are capabilities of AI Builder within Power Platform? (Choose three.)

Accepted Answer

Text recognition (OCR) from images and PDFs.. Option A is correct because AI Builder provides a prebuilt text recognition (OCR) capability that extracts printed or handwritten text from images and PDF documents. Option C is correct because AI Builder includes prebuilt object detection models that identify and locate objects within images. Option D is correct because AI Builder offers form processing models that extract structured data such as key-value pairs and tables from documents like invoices and receipts. Option B is not correct because AI Builder is designed for prebuilt and customizable prebuilt models, not for training custom machine learning models entirely from scratch. Option E is not correct because building custom user interfaces for mobile apps is a Power Apps capability, not an AI Builder capability.

Answer

Custom machine learning model training from scratch.

Answer

Building custom user interfaces for mobile apps.

Question 15

A company wants to enable employees to ask questions about HR policies using a conversational interface. The system should be built with minimal code. Which Power Platform capability should they use?
