The answer is to reinstall the on-premises data gateway and verify it appears online in the Power Platform admin center. This is correct because even when the gateway service is running locally and the server has internet connectivity, the gateway’s cloud-side registration in Azure can become corrupted or disconnected, causing the Power Platform to report it as offline. Reinstalling forces a fresh registration with the cloud service, resolving the underlying sync issue that a simple service restart cannot fix. On the PL-900 exam, this scenario tests your understanding that gateway connectivity depends on both the local service and its cloud registration—a common trap is assuming a running service means the gateway is fully functional. Remember, if the gateway shows offline in the admin center despite a running service, a clean reinstall is the reliable fix. Memory tip: “Service runs, cloud stalls—reinstall to fix the walls.”
PL-900 Practice Question: Demonstrate the capabilities of Power Automate
This PL-900 practice question tests your understanding of demonstrate the capabilities of power automate. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Reinstall the on-premises data gateway and verify it appears online in the Power Platform admin center
Option C is correct because the gateway can become unavailable if the associated Azure service (cloud service) is down or if the gateway's status in the Power Platform admin center shows as offline. Reinstalling the gateway is a common fix. Option A is incorrect because the gateway service is already running; restarting may not fix underlying issues. Option B is incorrect because the flow requires the gateway; removing it would break the connection. Option D is incorrect because the issue is gateway connectivity, not firewall rules for SQL Server.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Restart the on-premises data gateway service on the server
Why it's wrong here
The service is already running; restarting may not resolve the issue if the gateway is not registered.
✗
Remove the gateway from the flow and use a direct connection
Why it's wrong here
Direct connection is not possible for on-premises data sources without a gateway.
✗
Configure the firewall on the on-premises server to allow outbound traffic to Azure
Why it's wrong here
The server has internet connectivity, so firewall is not the issue.
✓
Reinstall the on-premises data gateway and verify it appears online in the Power Platform admin center
Why this is correct
Reinstalling can fix registration issues and ensure the gateway is recognized.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
