PL-900 Practice Test 36 — 15 Questions

Question 1

You are a Power Platform administrator. A user reports that a Power Automate flow that connects to SharePoint Online fails intermittently with a '403 Forbidden' error. The flow uses a service principal with application permissions. What is the most likely cause?

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

Accepted Answer

The service principal lacks the necessary SharePoint API permissions or admin consent.. A 403 Forbidden error specifically indicates that the server understood the request but refuses to authorize it. Since the flow uses a service principal with application permissions, the most likely cause is that the service principal lacks the necessary SharePoint API permissions or that admin consent has not been granted for those permissions. Without proper permissions or consent, SharePoint Online rejects the request regardless of authentication validity.

Answer

The flow is exceeding the SharePoint Online API throttling limits.

Answer

The service principal has been disabled in Microsoft Entra ID.

Answer

SharePoint Online is experiencing a service outage.

Question 2

A Power Apps app uses a Dataverse table with a choice column 'Priority' (Low, Medium, High, Critical). The app must display the priority as a color-coded badge in a gallery. Which method is most efficient?

Accepted Answer

Use the Switch function in the gallery's Fill property to map each choice value to a color.. The Switch function evaluates a single expression against multiple possible values and returns a corresponding result, making it the cleanest and most efficient way to map four choice values to four colors in one formula. It is more readable and performs better than nested If statements because it evaluates the expression once. This is the idiomatic Power Apps pattern for choice-to-color mapping.

Answer

Add a second table with colors and use LookUp in the gallery.

Answer

Create a Power Automate flow to update a color field on the record.

Answer

Use an If function with multiple conditions to set the Fill property.

Question 3

Which Power Platform component provides a low-code platform to build custom business applications that can be embedded in Microsoft Teams?

Accepted Answer

Power Apps. Power Apps is the correct answer because it is the low-code platform within Microsoft Power Platform specifically designed for building custom business applications. These apps can be directly embedded into Microsoft Teams via the 'Power Apps' tab or personal app, allowing users to interact with the app without leaving the Teams interface.

Answer

Power BI

Answer

Power Virtual Agents

Answer

Power Automate

Question 4

An app maker wants to add a button in a model-driven app that, when clicked, creates a new record of a custom entity called 'Inspection'. The maker should use which feature?

Accepted Answer

Custom command on the command bar. A custom command can be added to the command bar in a model-driven app to create a new record for a custom entity. Option B (Power Automate flow) is wrong because while a flow can be triggered from a command, the question is about the feature used to add the button itself. Option C (Business rule) is wrong because business rules are used for validation and show/hide logic, not for adding buttons. Option D (Form editor) is wrong because the form editor is used for form layout, not for adding command bar buttons.

Answer

Power Automate flow

Answer

Business rule

Answer

Form editor

Question 5

You have a Power Automate flow that sends a notification to a Teams channel when a high-priority ticket is created in Dynamics 365. The flow works correctly for most tickets, but occasionally a ticket is missed. Upon checking the flow runs, you see that some runs show 'Skipped' status. What is the most likely cause?

Accepted Answer

The trigger has a condition that filters out tickets with priority lower than 'High'.. The 'Skipped' status in Power Automate indicates that the flow was triggered but the trigger condition evaluated to false. In this scenario, the trigger has a condition that only allows high-priority tickets to proceed. When a ticket is created with a priority lower than 'High', the condition fails and the run is skipped. Option A correctly identifies this filter. Option B is incorrect because licensing issues would typically cause errors, not skips. Option C is wrong because high concurrency leads to queuing not skipping. Option D is incorrect as expired connections would cause failure, not skip.

Answer

The flow requires a premium license, but some users have standard licenses.

Answer

The flow's concurrency setting is too high, causing some triggers to be ignored.

Answer

The flow uses a connection that has expired or lacks permissions.

Question 6

You are troubleshooting a Power Automate flow that uses an HTTP action to call a REST API. The flow fails with a '429 Too Many Requests' error. The API has a rate limit of 100 requests per minute. Which strategy should you implement to handle this error gracefully?

Accepted Answer

Implement retry logic with exponential backoff in the HTTP action settings.. Implementing retry logic with exponential backoff allows the flow to automatically retry the request after a delay that increases with each attempt, which is the standard approach to handle rate limiting (HTTP 429 errors) and reduces server load. Option B is wrong because increasing concurrency would send more requests simultaneously, likely exacerbating the rate limit issue. Option C is wrong because simply ignoring 429 errors means requests are not retried and the action fails. Option D is wrong because 'Configure Run After' can handle failures but does not implement backoff, so it would not effectively manage rate limits.

Answer

Increase the flow's concurrency setting to process more requests simultaneously.

Answer

Use a 'Condition' action to check the status code and ignore 429 errors.

Answer

Use the 'Configure Run After' option to skip the action on failure.

Question 7

You need to design a Power Automate flow that sends a welcome email to a new user immediately after their account is created in Microsoft Entra ID. Which trigger should you use?

Accepted Answer

When a user is added. 'When a user is added' triggers when a new user is created. Option A is wrong because it triggers when a user is deleted, not created. Option B is wrong because it triggers when a group is added, not a user. Option C is wrong because it triggers when a user is updated, not created.

Answer

When a user is removed

Answer

When a group is added

Answer

When a user is updated

Question 8

You need to create a flow that runs on the first day of every month and sends a summary email of all new SharePoint list items added in the previous month. The email should be sent to the sales team. Which type of flow should you create?

Accepted Answer

Scheduled cloud flow. A scheduled cloud flow can run on a recurring schedule (e.g., first day of month) and includes actions to query SharePoint and send email. Automated flows trigger on events, not schedules. Desktop flows are for desktop automation. Business process flows guide users through stages.

Answer

Business process flow

Answer

Desktop flow

Answer

Automated cloud flow

Question 9

Fabrikam, Inc. uses Power Apps to create a canvas app for expense reporting. The app is connected to a SharePoint list named Expenses. The app allows users to submit expenses, attach receipts, and view their history. The manager wants to add a feature where users can scan a receipt using the mobile app camera and automatically extract the amount and date using AI Builder. The extracted data should be populated into the form fields. The development team needs to implement this feature. Which steps should they take?

Accepted Answer

Use AI Builder's receipt processing model in Power Apps. AI Builder provides a prebuilt receipt processing model that can be directly integrated into a Power Apps canvas app. This model allows users to scan a receipt using the camera, automatically extract the amount and date, and populate those values into form fields. Option B is incorrect because while a Power Automate flow could also process the image, it is an unnecessary extra step when AI Builder can be used directly within Power Apps. Option C is incorrect because the Camera control alone cannot extract text from an image; it requires additional processing like AI Builder. Option D is incorrect because Microsoft Copilot Studio is designed for building chatbots, not for receipt scanning and data extraction.

Answer

Create a Power Automate flow that processes the image and returns the data

Answer

Use the Camera control to capture the image and use a custom formula to extract text

Answer

Integrate Microsoft Copilot Studio to handle the receipt scanning

Question 10

A university uses Power Pages to create an alumni portal where graduates can update their contact information, register for events, and make donations. The portal uses Dataverse and allows both authenticated and anonymous access. The university wants to comply with GDPR and allow users to request deletion of their personal data. They need a mechanism for users to submit a deletion request, which then triggers a manual review process before data is deleted. You need to implement this in Power Pages with minimal effort. What should you do?

Accepted Answer

Build a custom form in Power Pages that submits to a Dataverse table 'Deletion Requests', and create a Power Automate flow that notifies admins and performs the deletion after approval.. Power Pages allows creating custom forms that submit data to Dataverse tables. By building a form that writes to a 'Deletion Requests' table, you can then trigger a Power Automate flow when a new record is created. The flow can send a notification to admins and, after manual approval, perform the actual deletion from Dataverse. This approach requires minimal custom code and leverages existing Power Platform integrations. Option A (manual email) is not automated and lacks audit trail. Option B (Azure Logic App with custom JavaScript) requires additional external configuration and custom scripting. Option C (legacy Power Apps portal) is outdated; Power Pages is the current product and offers native Dataverse integration. Option D is the correct and minimal-effort solution.

Answer

Add a hyperlink to the portal that sends an email to an admin mailbox, and have admins manually delete the data.

Answer

Use an Azure Logic App to expose an HTTP endpoint, and have the portal send data via a custom JavaScript call.

Answer

Create a Power Apps portal (legacy) form that writes to a 'Deletion Requests' Dataverse table and configure a Business Process Flow for review.

Question 11

A sales team uses a Power Automate flow that creates a contact in Dynamics 365 Sales whenever a new lead is added to a Salesforce system. The flow has been running successfully for months, but recently it started failing with an authentication error. What is the most likely cause?

Accepted Answer

The Salesforce connection credentials have expired. Authentication errors typically occur when the connection credentials for the connected service (Salesforce) expire or are revoked. Option A is incorrect because exceeding execution quotas would cause flow failures but not specifically authentication errors. Option B is incorrect because schema changes would cause data conversion or mapping errors, not authentication errors. Option C is incorrect because API rate limits would produce throttling errors (e.g., HTTP 429), not authentication errors.

Answer

The flow has exceeded its daily execution quota

Answer

The lead entity schema in Salesforce has changed

Answer

The flow is hitting API rate limits

Question 12

A company wants to build a canvas app to allow field technicians to report equipment issues from their mobile devices. The app must work offline and sync data when connectivity is restored. Which feature should the developer use?

Accepted Answer

Offline. Power Apps canvas apps support offline capability using the Offline feature, which caches data on the device and syncs when connectivity is restored. Option A (Power Automate) is a workflow automation tool, not an offline data sync feature. Option B (Power Platform admin center) is used for administration and governance, not for app-level offline capabilities. Option C (Common Data Service, now Microsoft Dataverse) is a data platform that can enable offline sync when used with the Offline feature, but the question specifically asks for the feature the developer should use, which is the Offline feature itself. Therefore, D is the correct answer.

Answer

Power Automate

Answer

Power Platform admin center

Answer

Common Data Service

Question 13

Which TWO permissions must be configured to allow authenticated users to submit a support ticket form in Power Pages?

Accepted Answer

Web role assignment for the authenticated user. Option C is correct because an authenticated user must be assigned a web role in Power Pages, since web roles are the mechanism that grants authenticated (and anonymous) users access to portal resources and are a prerequisite for any table access. Option E is correct because submitting a support ticket form creates a record in the Dataverse support ticket table, and table permissions (with the appropriate Create privilege) must be configured and associated with the user's web role to allow that record creation. Option A is incorrect because site settings control portal-wide configuration values and behavior, not user authorization to create records. Option B is incorrect because content snippets store reusable content fragments and have nothing to do with record-level access. Option D is incorrect because page permissions govern whether a user can view a given web page, not whether the form's underlying table record can be created.

Answer

Site setting permissions

Answer

Content snippet permissions

Answer

Page permissions for the support page

Question 14

Which TWO of the following are capabilities of Power Pages?

Accepted Answer

Integrate with Dataverse for data storage. Power Pages is Microsoft's low-code platform for building secure, external-facing business websites, so option E is correct: it lets makers create external-facing websites without code using templates, the design studio, and prebuilt components. Option A is also correct because Power Pages stores and surfaces data in Microsoft Dataverse, using Dataverse tables, forms, lists, and web roles/permissions to drive the site's content and interactions. Option B is not a Power Pages capability; complex machine learning models are typically built and run in Azure Machine Learning or Power Platform AI Builder, not in Power Pages itself. Option C is not correct for Power Pages because business process automation with workflows is provided by Power Automate (cloud flows) rather than being a native Power Pages capability. Option D is not correct because custom iOS and Android mobile apps are built with Power Apps mobile or native development tools, whereas Power Pages produces responsive web portals, not native mobile apps.

Answer

Run complex machine learning models

Answer

Automate business processes using workflows

Answer

Build custom mobile apps for iOS and Android

Question 15

Which TWO data sources can be used with a canvas app? (Choose two.)

Accepted Answer

SharePoint list. SharePoint lists (C) are a supported data source for canvas apps: you connect via the SharePoint connector, and the app can read/write list items using functions like Filter, Patch, and Collect against the list's fields. Microsoft Dataverse (E) is also a first-class native data source for canvas apps, exposing tables through the Dataverse connector with delegation support and rich data types. Power Platform (A) is the overall platform/suite, not a data source you connect to, and Power Automate (D) is a flow/automation service rather than a data source for the app. Microsoft Teams (B) is a collaboration client that can host canvas apps, but it is not itself a data source.

Answer

Microsoft Power Platform

Answer

Microsoft Teams

Answer

Power Automate
