Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The SQL query is taking longer than the allowed timeout.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The service account does not have write permission to the SharePoint list.
Why it's wrong here
Permission errors return 401 or 403.
- ✓
The SQL query is taking longer than the allowed timeout.
Why this is correct
GatewayTimeout indicates the request exceeded the timeout limit.
- ✗
The on-premises data gateway is offline.
Why it's wrong here
Gateway offline would cause a connection error, not timeout.
- ✗
The flow has exceeded the daily API call limit.
Why it's wrong here
Throttling results in 429 errors.
