PL-900 Describe the business value of Microsoft Power Platform Practice Test 2 — 15 Questions

Question 1

You are a Power Platform administrator. A user reports that they cannot create a new environment in the Power Platform admin center. The user has a Power Apps per user plan license. What is the most likely reason?

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

Accepted Answer

The user does not have a license that includes environment creation rights, such as Power Apps Plan 2 or Power Automate Plan 2.. Creating environments in the Power Platform admin center requires a license that includes environment creation rights, such as Power Apps Plan 2 or Power Automate Plan 2. The user's Power Apps per user plan license only allows them to use apps and flows, not to create or manage environments. Without the appropriate license, the environment creation option is disabled in the admin center.

Answer

The user does not have access to the Power Platform admin center.

Answer

The user is not a global administrator in Microsoft Entra ID.

Answer

The user has not assigned the license to themselves.

Question 2

Refer to the exhibit. A Power Platform environment uses Data Loss Prevention (DLP) policy with this JSON snippet. What is the effect of this policy rule?

Accepted Answer

It blocks all connectors for accounts in Seattle.. The JSON snippet defines a DLP policy rule that applies to the 'Seattle' environment. It sets the connector classification to 'Blocked' for all connectors, meaning no connectors can be used in that environment. Therefore, the correct effect is that all connectors are blocked for accounts in Seattle, making option D correct.

Answer

It requires approval for connectors accessing Seattle accounts.

Answer

It allows all connectors for accounts outside Seattle.

Answer

It classifies connectors as Business for accounts in Seattle.

Question 3

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.. 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 4

Which TWO of the following are advantages of using Power BI dashboards over Power BI reports?

Accepted Answer

Dashboards can show data from multiple reports on one page.. Option A is correct because a Power BI dashboard is a single canvas that can be composed of tiles pinned from many different reports and datasets, letting you consolidate visuals from multiple sources onto one page, whereas a report is bound to a single dataset. Option C is correct because dashboards natively include the Q&A experience, allowing users to ask natural-language questions and get visuals, a capability tied to the dashboard surface rather than the report canvas. Option B is not an advantage specific to dashboards: drill down (and drill through) is a report feature, and dashboards generally offer limited interactivity such as tile focus and Q&A rather than full drill-down hierarchies. Option D is not a dashboard-only advantage because reports can also be exported to PDF, so it does not distinguish dashboards from reports.

Answer

Dashboards allow users to drill down into details.

Answer

Dashboards can be exported to PDF.

Question 5

An organization has deployed a Power Automate flow that processes sensitive customer data. The security team requires that the flow's connections use managed identities instead of user credentials. What should the administrator do?

Accepted Answer

Use managed identities for the connections where supported.. Managed identities in Power Automate allow connections to authenticate to Azure resources without storing credentials, directly addressing the security team's requirement to avoid user credentials. Managed identities are a secure, Microsoft Entra ID-backed identity that can be assigned to a flow or environment, eliminating the need for shared secrets or user context.

Answer

Share the flow with the security team and have them modify the connections.

Answer

Use a service principal with a certificate and store the certificate in the flow's environment.

Answer

Store the user credentials in Azure Key Vault and reference them in the flow.

Question 6

A hospital uses Power Virtual Agents to create a chatbot for patient appointment scheduling. The chatbot needs to check real-time availability from a legacy scheduling system that has an API. What is the best way to integrate?

Accepted Answer

Use Power Automate as a custom connector to call the API.. B is correct because Power Automate can act as a custom connector to call the legacy scheduling system's API, enabling real-time availability checks. This integration allows the Power Virtual Agents chatbot to trigger a Power Automate flow that queries the API and returns the results directly to the user. It is the most direct and efficient method for connecting to external APIs without additional layers.

Answer

Embed a Power BI report in the chatbot to show availability.

Answer

Use Power Pages to expose the scheduling system.

Answer

Create a Power Apps portal for the chatbot to query.

Question 7

Refer to the exhibit. A Power Automate flow uses this custom connector configuration. The flow fails with an authentication error. What is the most likely cause?

Accepted Answer

The client secret is missing.. The custom connector is configured to authenticate using Microsoft Entra ID OAuth 2.0 with a client ID and tenant ID, but the client secret field is empty. Without a valid client secret, the connector cannot obtain an access token from Microsoft Entra ID, resulting in an authentication error. The other options relate to resource names (database, server) or tenant ID, which would produce different errors (e.g., connection failure or invalid tenant) rather than an authentication failure.

Answer

The database name is misspelled.

Answer

The server name is incorrect.

Answer

The tenant ID is invalid.

Question 8

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.. 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 9

Refer to the exhibit. A Power BI developer creates a DAX measure named 'SalesByRegion' as shown. The measure does not appear in the field list. What is the most likely issue?

Accepted Answer

The expression creates a table, not a scalar measure.. DAX measures must return a single scalar value (e.g., a number, date, or string) to appear in the Fields list of a Power BI report. The SUMMARIZE function returns a table with rows and columns, not a scalar, so Power BI treats it as a table expression and does not display it as a measure. Measures that return tables can only be used in other DAX expressions or as calculated tables, not directly in visuals.

Answer

The 'Sales' table does not exist.

Answer

The SUMMARIZE function syntax is incorrect.

Answer

The measure name must be enclosed in single quotes.

Question 10

Refer to the exhibit. You are reviewing a Power Apps app definition. Based on the exhibit, which connector does the app use?

Accepted Answer

Microsoft Dataverse. The exhibit shows a Power Apps app definition that includes a reference to a Microsoft Dataverse table (e.g., 'Accounts' or 'Contacts') as the data source. Dataverse is the native data platform for Power Apps, providing relational tables, business logic, and security directly within the Power Platform. The connector used is Microsoft Dataverse, which is the default connector when building canvas or model-driven apps with Dataverse tables.

Answer

Office 365 Users

Answer

SQL Server

Answer

SharePoint

Question 11

A sales team wants to automate follow-up emails after a lead is created in Dynamics 365 Sales. Which Power Platform component should they use?

Accepted Answer

Power Automate. Power Automate is the correct component because it is designed to create automated workflows that trigger actions based on events, such as sending follow-up emails when a lead is created in Dynamics 365 Sales. It integrates directly with Dynamics 365 via connectors, allowing you to define a trigger (e.g., 'When a lead is created') and an action (e.g., 'Send an email') without custom code.

Answer

Power BI

Answer

Power Apps

Answer

Power Virtual Agents

Question 12

Which THREE are benefits of using Dataverse as the data platform for Power Platform solutions?

Accepted Answer

Built-in role-based security and auditing. Option B is correct because Dataverse natively provides role-based security (security roles, business units, teams, and field-level/record-level privileges) plus built-in auditing that logs create, update, delete, and access operations without custom code. Option C is correct because Dataverse is a first-class data source for AI Builder, allowing models such as form processing, prediction, and document processing to be trained and run directly against Dataverse tables. Option E is correct because Dataverse is the underlying data platform for Dynamics 365 apps (Sales, Customer Service, Field Service, etc.), so Power Platform solutions can read and write Dynamics 365 data through the same Common Data Model tables and business logic. Option A is incorrect because Dataverse does not expose T-SQL query support; it uses the Web API (OData) and the Organization Service, and while it is relational, direct T-SQL access is not a supported capability. Option D is incorrect because Dataverse storage is not free or unlimited; it is licensed with capacity entitlements (database, file, and log storage) that can incur additional cost when exceeded.

Answer

Full relational database capabilities with T-SQL support

Answer

Free unlimited storage for all data types

Question 13

An administrator creates the DLP policy shown above. Which of the following actions will be blocked?

Accepted Answer

Creating a flow that uses SharePoint and Salesforce. The DLP policy shown blocks the SharePoint connector, and creating a flow that uses both SharePoint and Salesforce would involve the SharePoint connector, which is prohibited by the policy. DLP policies in Power Platform restrict specific connectors from being used together in the same app or flow, and since SharePoint is blocked, any flow that includes it is prevented from being created or run.

Answer

Using Power Apps with Dataverse

Answer

Creating a flow that uses Dataverse and SQL Server

Answer

Using Power BI with SQL Server

Question 14

A Power BI report uses the KQL query shown. What is the purpose of this query?

Accepted Answer

To show total sales per product category for North America in descending order. The KQL query uses the `summarize` operator to group sales data by `ProductCategory` and calculate the total sales amount using `sum(SalesAmount)`. The `where` clause filters for `Region == 'North America'`, and `order by` sorts the aggregated results in descending order. This produces a list of product categories with their total sales for North America, sorted from highest to lowest.

Answer

To list all sales transactions for North America

Answer

To calculate average sales amount by region

Answer

To filter sales data by product category

Question 15

An administrator configures a Power Platform tenant-level policy with the JSON shown. What is the effect of this policy?

Accepted Answer

It restricts all users from accessing any Power Platform environment. The JSON policy sets the 'blocked' property to true for all environments, which effectively denies all users (including admins) access to any Power Platform environment. This is a tenant-level restriction that overrides individual environment permissions, making it impossible for anyone to interact with Power Apps, Power Automate, or Power Virtual Agents within the tenant.

Answer

It allows only admins to manage environments

Answer

It prevents data export from environments

Answer

It blocks all users from creating new environments
