PL-900 Practice Question: Demonstrate the capabilities of Power Automate
A Power Automate flow fails with the error 'GatewayTimeout'. The flow uses an on-premises data gateway to connect to a SQL Server database. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The on-premises data gateway is offline or unreachable.
A GatewayTimeout error typically indicates that the gateway is not reachable or has been offline due to network issues, maintenance, or misconfiguration. Option A is wrong because incorrect credentials would cause authentication errors, not timeout. Option B is wrong because a misconfigured trigger would cause a different error at flow start. Option D is wrong because insufficient license would cause a quota or permission error.
