PL-900 Practice Exam 52 — 20 Questions

Question 1

A model-driven app shows a custom form with fields from two related tables: Order and Customer. The form is set to display the Customer fields as a subgrid. Users want to see Customer details inline without navigating away. What should the app maker do?

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

Accepted Answer

Use a quick view form for the Customer table. Quick view forms allow displaying related entity fields inline. Subgrids show lists, not detail fields. Custom pages are for canvas experiences. Form sections don't add inline detail from other tables.

Answer

Add a new form section for Customer fields

Answer

Create a custom page with a canvas control

Answer

Add a subgrid for the Customer table

Question 2

A company has a legacy on-premises SQL Server database and wants to integrate it with a Power App without moving data to the cloud. Which connector should they use?

Accepted Answer

On-premises data gateway with SQL Server connector. The On-premises data gateway acts as a secure bridge between cloud services like Power Apps and on-premises data sources such as SQL Server. When combined with the SQL Server connector, it allows live queries and updates to the on-premises database without requiring data migration to the cloud, fulfilling the requirement to keep data on-premises.

Answer

SQL Server connector directly

Answer

Power Automate on-premises agent

Answer

Dataverse

Question 3

Which TWO components are required to create a Power Automate flow that sends an email when a new item is added to a SharePoint list? (Choose two.)

Accepted Answer

A trigger. A trigger is required because a Power Automate flow must have a starting event to initiate execution. For a SharePoint list, the 'When an item is created' trigger fires automatically when a new item is added, which is the necessary first step before any actions can run.

Answer

An approval action

Answer

A variable

Answer

A condition

Question 4

A flow fails with the error: 'GatewayTimeout'. The flow connects to an on-premises SQL Server via a data gateway. What is the most likely cause?

Accepted Answer

The on-premises data gateway is not running or unreachable. The 'GatewayTimeout' error indicates that the flow successfully reached the on-premises data gateway but the gateway did not respond within the expected time frame. This typically occurs when the gateway service is not running, the machine hosting the gateway is offline, or network connectivity between the gateway and the SQL Server is broken. Incorrect credentials or missing tables would produce different errors (e.g., 'Login failed' or 'Invalid object name').

Answer

The SQL login credentials are incorrect

Answer

The SQL table does not exist

Answer

The flow trigger did not fire

Question 5

A company needs to ensure that all Power Apps and Power Automate flows in the 'Development' environment are automatically backed up daily. What should the administrator configure?

Accepted Answer

Enable Dataverse backups for the Development environment. Dataverse backups are automatically enabled for environments with a Dataverse database, including the Development environment. These backups occur daily and capture the entire environment state, which includes all data, apps (canvas and model-driven), and Power Automate flows stored within Dataverse. No additional configuration is required, making it the simplest way to ensure automatic daily backups of Power Apps and Power Automate flows.

Answer

Enable the 'Backup Policy' in the Power Platform admin center for the Development environment

Answer

Schedule a daily export of all solutions using the Power Platform admin center

Answer

Use the 'Solution Backup' feature in the Power Platform admin center

Question 6

A developer is trying to create a business process flow (BPF) for the 'Opportunity' table in a model-driven app. When activating the BPF, the developer receives the error shown in the exhibit. What is the most likely cause?

Accepted Answer

The BPF is trying to use a table that is not enabled for business process flows.. The error shown in the exhibit indicates that the business process flow (BPF) references a table that is not enabled for business process flows. In Power Apps, only tables that have the 'Business process flows' option enabled in their table settings can be used as the primary entity for a BPF. The 'Opportunity' table is a standard table that is enabled by default, but if it has been disabled or the BPF is referencing a custom table that lacks this setting, activation will fail with this error. Option C correctly identifies this root cause.

Answer

The developer does not have sufficient security role permissions to activate BPFs.

Answer

The BPF has no stages defined.

Answer

The Opportunity table does not exist.

Question 7

Which FOUR of the following are core components of Microsoft Power Platform?

Accepted Answer

Power BI. The question asks for four core components of Microsoft Power Platform. Power BI, Power Virtual Agents, Power Apps, and Power Automate are all core components. Thus, all four options (A, B, D, E) are correct.

Answer

Microsoft 365

Question 8

A sales team wants to quickly create a mobile app to track customer visits without writing code. Which Microsoft Power Platform component should they use?

Accepted Answer

Power Apps. Power Apps is the correct choice because it enables users to build custom mobile apps with a low-code or no-code approach, specifically designed for creating data-driven applications like a customer visit tracker. The sales team can connect to data sources (e.g., Dataverse, SharePoint, or Excel) and design a mobile-friendly interface without writing any code, making it ideal for quickly tracking customer visits.

Answer

Power Automate

Answer

Power Virtual Agents

Answer

Power BI

Question 9

You are a Power BI administrator for a retail company. The sales team uses a Power BI report that connects to an on-premises SQL Server database via an on-premises data gateway. Recently, several users reported that the report is showing stale data. The report is configured to refresh daily at 8:00 AM. Upon investigation, you find that the scheduled refresh failed last night at 8:00 AM with an error: 'The data source credentials could not be encrypted using the gateway's encryption key.' The gateway is installed on a server that was rebooted for maintenance at 7:30 AM. The gateway service account is a local service account. The data source credentials were configured using a SQL Server authentication login. What should you do to resolve the issue?

Accepted Answer

In the Power BI Online service, go to the gateway settings and click 'Recover' to restore the encryption key.. The error 'The data source credentials could not be encrypted using the gateway's encryption key' indicates that the gateway's encryption key was lost or corrupted, which commonly occurs after a server reboot if the key is stored in memory or a volatile location. In the Power BI Online service, the 'Recover' option under gateway settings restores the encryption key from a backup stored in the cloud, allowing the gateway to re-encrypt credentials without reconfiguring the data source. This is the direct fix for the reported error and does not require changing the service account or recreating the data source.

Answer

Change the gateway service account to a domain account and reconfigure the data source credentials.

Answer

Restart the on-premises data gateway service on the server.

Answer

Delete and recreate the data source in the gateway settings.

Question 10

Your organisation has a Power Apps canvas app that uses a custom connector to call an external API. The API key is stored in a global variable. What is the security concern with this approach?

Accepted Answer

The API key can be exposed to end users in the app code.. Storing an API key in a global variable within a Power Apps canvas app is insecure because the app's code is accessible to end users. Anyone with access to the app can view the global variable's value through the App object or by inspecting the app's formulas, potentially exposing the API key. The correct answer is D. Option A is incorrect because custom connectors can be used with Power Apps. Option B is incorrect because global variables in Power Apps are writable, not read-only. Option C is incorrect because API keys typically do not expire quickly; the security concern is exposure, not expiration.

Answer

The custom connector cannot be used with Power Apps.

Answer

Global variables cannot store API keys because they are read-only.

Answer

The API key will expire quickly.

Question 11

Refer to the exhibit. A Power BI dashboard is configured with the shown data sources. The dashboard fails to refresh automatically. What is the most likely cause?

Accepted Answer

The SQL Server data source requires an on-premises data gateway. The dashboard refreshes automatically but fails. The data sources shown are an Excel file stored on SharePoint (supported, no gateway needed) and an on-premises SQL Server (server name indicates on-premises). For Power BI service to access on-premises data, an on-premises data gateway must be installed and configured. Without it, the SQL Server connection will fail during refresh. Options A and D are incorrect because daily frequency and using two data sources are not issues. Option B is incorrect because SharePoint is a supported location for Excel files. Therefore, the most likely cause is that the SQL Server data source requires an on-premises data gateway.

Answer

The refresh frequency is set to daily, which is too infrequent

Answer

The Excel file is stored in an unsupported location

Answer

The dashboard uses two data sources, but only one is allowed

Question 12

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 13

A company uses Power Automate to process purchase orders. After a recent update, the flow fails intermittently with a '429 Too Many Requests' error. What is the most likely cause?

Accepted Answer

The flow is exceeding Power Platform service protection limits.. The '429 Too Many Requests' error is an HTTP status code indicating rate limiting. In Power Automate, this occurs when a flow exceeds the Power Platform service protection limits, which are designed to prevent resource overconsumption. These limits include API request caps (e.g., 30 requests per 60 seconds per connection) and daily invocation quotas (e.g., 5,000 requests per day for a per-user plan). The error is not related to authentication expiry, outdated flow versions, or data source availability.

Answer

The flow uses an expired connector authentication.

Answer

The flow is running an outdated version.

Answer

The data source is temporarily unavailable.

Question 14

A Power Automate flow that sends approval requests is being used by multiple teams. The flow uses the 'Start and wait for an approval' action. The approver reports that they are not receiving the approval request email. What should you check first?

Accepted Answer

The Approvals connector is not properly configured. The 'Start and wait for an approval' action relies on the Approvals connector to send approval requests. If the connector is not properly configured (e.g., missing required connections or permissions), the approval email may not be sent. Option A is wrong because the flow owner's mailbox does not directly affect approval delivery. Option C is wrong because a successful flow run history indicates the action executed, but does not guarantee the email was delivered. Option D is wrong because the approver's email address is defined within the 'Start and wait for an approval' action; if it were incorrect, the flow would likely fail, but the issue here is about email delivery, not address validity.

Answer

The flow owner's mailbox is full

Answer

The flow run history shows a success

Answer

The approver’s email address is incorrect in the flow

Question 15

A model-driven app for project management uses a custom entity 'Project' with a status field. The app maker wants to show a timeline of project phases using a timeline control. What must be configured for the timeline to display correctly?

Accepted Answer

Create an activity entity for project phases and relate it to the Project entity.. The timeline control requires a relationship to an activity entity (like Appointment) or a custom entity configured as an activity. Option A is wrong because the timeline does not require a specific field. Option B is wrong because timeline does not use subgrid. Option D is wrong because timeline is not a standard SharePoint integration.

Answer

Add a subgrid of project phases and configure it as a timeline.

Answer

Set the timeline control's date field to the project start date.

Answer

Integrate with Microsoft Project for timeline data.

Question 16

A sales team wants to automate lead assignment based on region without writing code. Which Microsoft Power Platform component should they use?

Accepted Answer

Power Automate. Power Automate is the correct choice because it enables users to create automated workflows that can assign leads based on region using conditional logic and data from sources like Dynamics 365 or SharePoint, all without writing code. It provides prebuilt connectors and triggers (e.g., 'When a lead is created') to automate business processes seamlessly.

Answer

Power Apps

Answer

Power BI

Answer

Power Virtual Agents

Question 17

An organization wants to allow external partners to access specific Power Apps and data without granting them full access to the tenant. What should they configure?

Accepted Answer

Invite partners as guest users in Microsoft Entra ID and assign them appropriate security roles in the Power Platform environment.. Inviting external partners as guest users in Microsoft Entra ID (formerly Azure AD) and assigning them appropriate security roles in the Power Platform environment is the standard method for providing controlled, least-privilege access to specific Power Apps and their underlying data sources. This approach leverages Microsoft Entra B2B collaboration to create guest identities, which can then be granted access to specific environments and resources without giving them full tenant-level permissions.

Answer

Use Microsoft Intune to manage partner devices.

Answer

Create a data loss prevention (DLP) policy that allows external sharing.

Answer

Share the app URL with the partners and ask them to sign in with their own accounts.

Question 18

In a model-driven app, a user wants to see a map of all customer addresses on a form. Which feature should be enabled?

Accepted Answer

Map control. The Map control in model-driven apps displays addresses on a map. Option A is wrong because the Notes section is for attaching notes to records. Option C is wrong because the Associated View shows related records in a list. Option D is wrong because the Timeline control shows activities and communications.

Answer

Notes section

Answer

Associated View

Answer

Timeline control

Question 19

A company wants to build a Power App that uses AI to analyze survey responses and extract sentiment. Which Power Platform capability should they use?

Accepted Answer

AI Builder sentiment analysis model. AI Builder (C) provides pre-built models for sentiment analysis. A is for reporting. B is for automation. D is for low-code, not AI.

Answer

Power BI dashboards

Answer

Power Automate flows

Answer

Power Apps Canvas app with formulas

Question 20

A company has multiple Power Platform environments. They want to automatically apply consistent settings (e.g., DLP policies, audit settings) to all new environments. What should they do?

Accepted Answer

Create an environment group in the Power Platform admin center and assign policies to the group.. Environment groups in the Power Platform admin center allow administrators to define a set of policies (such as DLP policies and audit settings) that are automatically applied to all environments within the group, including newly created ones. This provides a centralized, no-code method to enforce consistent governance across multiple environments without manual intervention.

Answer

Use PowerShell scripts to configure each environment after creation.

Answer

Use Azure Blueprints to define and apply a set of Azure resources.

Answer

Use Microsoft Intune to enforce settings on Power Platform environments.
