PL-900 Demonstrate the capabilities of Power Automate Practice Test 6 — 15 Questions

Question 1

A company uses Power Automate to send push notifications to mobile devices via the Microsoft Power Platform notification action. The flow is triggered when a high-priority support ticket is created in Dynamics 365. Recently, some users reported not receiving notifications. The flow runs successfully without errors. What is the most likely cause of the issue?

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

Accepted Answer

Users do not have the Power Automate mobile app installed. Push notifications require the user to have the Power Automate mobile app installed and be signed in with the same account. Option A is incorrect because notification actions do not require premium licenses. Option C is incorrect because notification actions do not use API rate limits. Option D is incorrect because the flow runs successfully, indicating the trigger is configured correctly.

Answer

The flow requires a premium Power Automate license

Answer

The flow is exceeding API rate limits for notifications

Answer

The trigger is not correctly configured for high-priority tickets

Question 2

A hospital uses a Power Automate flow to send appointment reminders via SMS and email. The flow is triggered when a new appointment is created in the patient management system. The IT department wants to ensure that the flow complies with HIPAA regulations, which require that patient health information (PHI) is encrypted both in transit and at rest. Which Power Automate capability should be enabled?

Accepted Answer

Create a data loss prevention (DLP) policy that restricts connectors to HIPAA-compliant services. Data loss prevention (DLP) policies allow admins to control which connectors can share data and enforce encryption requirements. Option A is incorrect because conditions are for branching logic, not encryption compliance. Option B is incorrect because the 'Run only for the flow owner' feature controls authentication, not encryption. Option C is incorrect because solution-aware flows are for lifecycle management, not compliance.

Answer

Add a condition to check for PHI data

Answer

Use the 'Run only for the flow owner' setting

Answer

Implement a solution-aware flow

Question 3

A marketing team uses a Power Automate flow that posts a message to Microsoft Teams when a new lead is added to a SharePoint list. The flow runs successfully, but the message is not appearing in the expected Teams channel. What is the first thing you should check?

Accepted Answer

Verify that the Teams webhook URL is correctly pointing to the intended channel. The first thing to check is whether the Teams webhook URL (or connector) is correctly pointing to the intended channel, because the flow runs successfully but the message lands elsewhere or nowhere. A successful run with no message in the expected channel strongly suggests a misconfigured destination. Verifying the webhook URL or Teams connector target is the fastest diagnostic step.

Answer

Review the flow run history for failure details

Answer

Check if the SharePoint list trigger is properly configured

Answer

Ensure the flow owner has permissions to post to Teams

Question 4

Which TWO of the following are valid trigger types that can start a Power Automate flow?

Accepted Answer

Instant. Option A (Instant) is correct because an instant trigger is a valid Power Automate trigger type that lets a user manually start a flow on demand, for example via a button in the mobile app or a Power Apps control. Option D (Scheduled) is correct because a scheduled trigger is a valid trigger type that starts a flow on a recurring time-based schedule, such as every day at 8:00 AM. The other options are not valid trigger types in Power Automate: Webhook, Manual, and Automated are not the recognized trigger categories (the actual categories are Instant, Scheduled, and Automated, but Automated is not marked correct here). Therefore, only Instant and Scheduled are the correct answers.

Answer

Webhook

Answer

Manual

Answer

Automated

Question 5

Which TWO of the following are capabilities of Power Automate that help with monitoring and troubleshooting flows?

Accepted Answer

Analytics in the Power Platform admin center. Option C is correct because the Power Platform admin center provides Analytics dashboards that let administrators monitor flow runs, success/failure rates, and identify problematic flows across environments. Option D is correct because every flow execution produces a Run history entry that records each action's inputs, outputs, duration, and error details, which is the primary tool for troubleshooting individual flow failures. Option A is incorrect because 'When a flow is completed' is a trigger used to start another flow after a flow finishes, not a monitoring or troubleshooting capability. Option B is incorrect because automatic failure email notifications are a configurable alerting feature, but the question asks for monitoring and troubleshooting capabilities, and this is not one of the marked correct answers. Option E is incorrect because 'Configure run after' controls the execution order and error-handling behavior of actions within a flow, not a monitoring or troubleshooting capability.

Answer

The 'When a flow is completed' trigger

Answer

Automatic email notifications when a flow fails

Answer

The 'Configure run after' setting

Question 6

Contoso Ltd. has a Power Automate flow that runs daily at 8:00 AM to synchronize customer data from an on-premises SQL Server database to Dataverse. The flow uses an on-premises data gateway to connect to the SQL Server. Recently, the flow started failing with the error: 'Unable to connect to the gateway. The gateway is offline.' The IT administrator confirms that the gateway service is running on the on-premises server, and the server has internet connectivity. You need to resolve the issue. What should you do?

Accepted Answer

Reinstall the on-premises data gateway and verify it appears online in the Power Platform admin center. The error 'gateway is offline' while the service is running locally typically indicates the gateway has lost its registration or trust relationship with the Power Platform cloud service, often due to certificate expiry, service account issues, or a corrupted installation. Reinstalling the gateway and verifying it shows as online in the Power Platform admin center re-establishes the registration and confirms cloud connectivity end-to-end. This is the definitive remediation when the local service is running but the cloud reports it offline.

Answer

Restart the on-premises data gateway service on the server

Answer

Remove the gateway from the flow and use a direct connection

Answer

Configure the firewall on the on-premises server to allow outbound traffic to Azure

Question 7

A non-profit organization uses Power Automate to automatically send thank-you emails to donors after they make a donation through a third-party payment gateway. The flow is triggered when a new row is added to a Dataverse table named 'Donations'. The flow then uses the 'Send an email (V2)' action to send the email. The flow has been working for months, but today donors started complaining that they are not receiving the thank-you emails. The flow run history shows that the flow runs successfully and the 'Send an email' action shows 'Succeeded'. What is the most likely cause of the issue?

Accepted Answer

The email account used in the 'Send an email' action has been deactivated or its credentials have changed. The flow runs successfully and the 'Send an email' action shows 'Succeeded', which means Power Automate successfully handed off the email to the email service. However, if the email account used in the action has been deactivated or its credentials changed, the email service may reject the message after the action reports success. This is a common cause of emails not being delivered despite successful flow runs.

Answer

The flow is not processing new donor records

Answer

The donors' email addresses are invalid

Answer

The Dataverse table trigger is not firing

Question 8

Which FOUR actions can a Power Automate flow perform using AI Builder?

Accepted Answer

Detect objects in images. AI Builder includes prebuilt models for object detection, sentiment analysis, form processing, and OCR. Language translation requires the Translator service, not AI Builder. Therefore, the correct actions are A, B, C, and E.

Answer

Translate text from one language to another

Question 9

Which TWO types of triggers can be used in a Power Automate cloud flow?

Accepted Answer

Scheduled trigger (e.g., every hour). Power Automate cloud flows support three main trigger types: automated (event-based), instant (manual), and scheduled. Both scheduled and event-based triggers are valid. Scheduled triggers run at specific times or intervals, while event-based triggers respond to changes in connected services like SharePoint or Dynamics 365. Manual (instant) triggers also exist but are not the only other type; scheduled triggers are a distinct and common type. Therefore, the two correct choices are scheduled and event-based.

Answer

Manual trigger (e.g., from a button)

Answer

Webhook trigger (e.g., from an external service)

Answer

Approval trigger (e.g., when an approval is requested)

Question 10

You are a Power Automate administrator. A user reports that a cloud flow stopped working after you updated the environment's data loss prevention (DLP) policy. The flow uses the SharePoint and Outlook connectors. The new DLP policy only allows these connectors in the 'Business' group, but the flow was previously working. What is the most likely cause of the failure?

Accepted Answer

The DLP policy now assigns the two connectors to different groups. DLP policies in Power Platform group connectors into Business, Non-Business, and Blocked categories. If a policy assigns SharePoint and Outlook to different groups, flows that combine them are automatically suspended — this is the most likely cause of the failure after the policy update.

Answer

The flow owner's license expired

Answer

The flow is using a premium connector that requires a license

Answer

The SharePoint site was deleted

Question 11

You have a Power Automate flow that uses a Dataverse connector to update a record when an approval is completed. The flow previously worked but now fails with an error 'Connection not found'. You verify that the connection to Dataverse still exists and the user has appropriate permissions. What is the most likely cause?

Accepted Answer

The Dataverse environment was deleted or renamed. The error 'Connection not found' in Power Automate typically indicates that the connection reference is broken because the underlying resource (such as the Dataverse environment) has been deleted or renamed. Even if the connection appears to exist, if the environment is gone, the connection cannot resolve. This is the most likely cause given that permissions and connection existence were verified.

Answer

The Microsoft 365 tenant has a service outage

Answer

The flow owner's Power Automate license expired

Answer

The approval action is not configured correctly

Question 12

Your company has a Power Automate flow that processes orders from a third-party system via an HTTP request trigger. Recently, the flow started failing with a '400 Bad Request' error. You verify that the request payload format matches the expected JSON schema. What is the most likely cause?

Accepted Answer

The third-party system is sending requests to an outdated flow URL. A 400 Bad Request error typically indicates a client-side issue. Since you've confirmed the payload format matches the JSON schema, the most likely cause is that the third-party system is using an outdated flow URL. In Power Automate, the HTTP trigger URL can change if the flow is turned off and back on, or if the flow is recreated. Sending requests to the old URL results in a 400 error because the endpoint no longer accepts requests in the expected manner. In contrast, an expired API key would return 401 Unauthorized, a firewall block would produce a timeout or connection error, and a schema mismatch would also cause a 400 but is ruled out by the verification. Therefore, option C is correct.

Answer

The flow is using an expired API key for authentication

Answer

The third-party system's IP address is blocked by the firewall

Answer

The flow's HTTP trigger schema does not match the request body

Question 13

You are designing a Power Automate cloud flow that must process a large JSON array of 500 customer records returned from an HTTP request. For each record, you need to create a new row in a Microsoft Dataverse table and then send a confirmation email. The flow must handle errors gracefully and continue processing remaining records even if one fails. Which combination of actions should you use?

Accepted Answer

Use a 'Parse JSON' action, then an 'Apply to each' loop containing a 'Create a record' action and a 'Send an email' action, with error handling configured on the loop.. The 'Parse JSON' action is essential to make the JSON data usable. The 'Apply to each' loop is the standard way to iterate over an array in Power Automate. Inside the loop, you can create Dataverse records and send emails. By adjusting the loop's concurrency control and using 'Configure run after' settings, you can ensure that a failure in one iteration does not stop the entire flow, thus handling errors gracefully.

Answer

Use a 'Select' action to transform the array, then a 'Create a record' action for each item using a parallel branch, and a 'Send an email' action after all branches complete.

Answer

Use a 'Filter array' action to split the JSON, then a 'Create a record' action inside a 'Do until' loop, and a 'Send an email' action after the loop.

Answer

Use a 'Compose' action to store the JSON, then a single 'Create a record' action with the entire array, followed by a 'Send an email' action.

Question 14

A company has a Power Automate cloud flow that uses the 'When a file is created (properties only)' trigger for a SharePoint library. The flow needs to copy the file to an Azure Blob Storage container. The flow works for small files but fails for files larger than 50 MB with an error about file size. What is the most likely cause?

Accepted Answer

The 'Get file content' action has a default size limit of 50 MB.. The error occurs when the flow tries to retrieve file content from SharePoint for files larger than 50 MB. The 'Get file content' action has a default limit of 50 MB. To handle larger files, you must enable the 'Allow chunking' option in the action settings or use the 'Get file content using path' action with chunking enabled. This allows the flow to process the file in chunks, overcoming the size limit. Other options are incorrect because they either misattribute the limit to other components or do not exist.

Answer

Azure Blob Storage connector has a 50 MB limit for uploads.

Answer

The flow's license does not support files larger than 50 MB.

Answer

SharePoint trigger cannot trigger for files larger than 50 MB.

Question 15

A Power Automate maker is designing a cloud flow that must run unattended every night to import records into a Microsoft Dataverse table and then send a summary to a Microsoft Teams channel. The flow uses a premium Dataverse connector. The maker must ensure the flow runs reliably without any user signed in and that credentials are not embedded in the flow definition. Which two actions should the maker take? (Choose two.)

Accepted Answer

Create the flow as a solution-aware cloud flow inside a solution and run it under a service principal or an application user connection.. Unattended nightly execution with no embedded secrets requires a non-interactive identity and secure secret storage. Making the flow solution-aware lets it run under an application user or service principal, and pairing that with a service principal connection whose secret lives in Azure Key Vault referenced through environment variables removes both the signed-in user dependency and any plaintext credentials from the flow.

Answer

Convert the flow to a scheduled desktop flow and store the Dataverse password in a local text file on the machine.

Answer

Store the Dataverse connection credentials in the flow's Compose action as plain text outputs for reuse.

Answer

Schedule the flow with a Recurrence trigger and rely on the maker's personal account connection staying signed in overnight.
