PL-900 Practice Test 16 — 15 Questions

Question 1

An organization uses Power BI to analyze sales data. They notice that the report takes over a minute to load, and they need to improve performance quickly without changing the data source. Which action should they take?

Accepted Answer

Reduce the number of visuals on the dashboard.. Option C is correct because reducing the number of visuals on a Power BI dashboard directly decreases the number of queries sent to the data model and the rendering workload, which can significantly improve load times without altering the data source. This is the quickest performance optimization available when the data source cannot be changed, as each visual typically triggers separate DAX queries and rendering processes.

Answer

Change the data source to use DirectQuery instead of Import.

Answer

Implement data aggregations in Power BI.

Answer

Create a new composite model.

Question 2

Refer to the exhibit. The JSON snippet represents an ARM template for deploying a Power Apps app. The deployment fails with an error that the environment 'Environment1' does not exist. What is the most likely reason?

Accepted Answer

The environment ID is not a full ARM resource ID.. Option D is correct because ARM templates require the environment to be specified as a full Azure resource ID (e.g., `/providers/Microsoft.PowerApps/environments/{environmentId}`) to uniquely identify the target environment across tenants and subscriptions. The error 'environment does not exist' indicates that the provided ID is likely a short name or GUID, not the full ARM resource path, so the deployment cannot resolve the environment.

Answer

The app name contains invalid characters.

Answer

The lifecycleId should be 'Development' instead of 'Production'.

Answer

The apiVersion is incorrect.

Question 3

A marketing department wants to create a custom portal where external partners can submit project proposals and track their status. Which Power Platform product should they use?

Accepted Answer

Power Apps portal (now Power Pages). Power Apps portals (now Power Pages) is the correct choice because it enables organizations to create low-code, externally facing websites that allow external users—such as partners—to sign in, submit project proposals, and track their status. It integrates with Microsoft Dataverse to store and manage the proposal data, and supports role-based access control to ensure partners only see their own submissions.

Question 12

You are the Power Platform administrator for a large enterprise with multiple departments. The HR department uses a Power Apps canvas app to manage employee onboarding. The app is connected to Dataverse and includes a flow that sends a welcome email via Power Automate. Recently, the IT security team mandated that all Power Platform solutions must use Microsoft Entra ID for authentication and that sensitive data (e.g., social security numbers) must be encrypted at rest. The HR app currently uses Dataverse's default encryption. Additionally, the HR team wants to extend the app to external contractors who do not have Microsoft Entra ID accounts. They need to be able to submit their personal information through a secure web form. You need to design a solution that meets security requirements and allows external access. What should you do?

Accepted Answer

Enable customer-managed encryption key (CMEK) for Dataverse, and create a Power Pages site with Microsoft Entra External ID authentication for external contractors.. Option B is correct because it addresses both security requirements: customer-managed encryption key (CMEK) for Dataverse ensures sensitive data like social security numbers is encrypted at rest with a key controlled by the enterprise, meeting the IT security mandate. Additionally, creating a Power Pages site with Microsoft Entra External ID authentication allows external contractors without Microsoft Entra ID accounts to authenticate via social or email-based identities, enabling secure submission of personal information through a web form while maintaining compliance.

Answer

Create a SharePoint list for external contractors to submit data, and use Power Automate to send emails.

Answer

Use Power Apps portals with Microsoft Entra ID B2B collaboration for external contractors, and leave encryption as default.

Answer

Implement a Power Automate flow to collect data via Microsoft Forms, and store results in Dataverse with default encryption.

Question 13

A global organization wants to standardize expense reporting across subsidiaries using Power Platform. They require integration with Microsoft Entra ID for identity and must ensure data residency compliance. Which TWO capabilities should they use?

Accepted Answer

Dataverse environments with specific regions. Dataverse environments can be created in specific geographic regions (e.g., Canada, France, UK) to ensure data residency compliance by storing data at rest within that region. Integration with Microsoft Entra ID is inherent to Dataverse, which uses Entra ID as its identity provider for authentication and authorization, meeting the requirement for standardized identity management across subsidiaries.

Answer

AI Builder

Power BI dashboards

Answer

Copilot Studio

Question 14

A university wants to create a system for students to register for extracurricular activities. The system should allow students to view available activities, sign up, and receive confirmation emails. Staff should be able to manage activities and view attendance reports. The university has Power Platform licenses but limited IT resources. Which solution should they implement?

Accepted Answer

Power Apps (model-driven) for staff, Power Apps (canvas) for students, Power Automate for emails, and Power BI for reports. Power Apps (model-driven) can be used by staff to manage activities, and a canvas app (or portal) can be used by students. Power Automate sends confirmation emails. Power BI can generate attendance reports. Option B is incorrect because Power Pages is an alternative but more complex. Option C is incomplete without Power Apps. Option D is incorrect because AI Builder is not needed.

Answer

AI Builder and Power Automate to process registrations

Answer

Power Automate for everything, with SharePoint lists for data storage

Answer

Power Pages for students, Power Automate for emails, and Power BI for reports
