PL-900 Demonstrate the capabilities of Power Apps Practice Question

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 SQL table name in the app formula is incorrect
The error 'The data source is not found' typically indicates that the app formula references a table name that does not exist or is misspelled in the SQL database. Option A is incorrect because missing environment variables cause different errors. Option B is incorrect because a deleted SharePoint list would affect SharePoint-based data sources, not SQL Server. Option D is incorrect because the gateway status shows 'Running' and the connection is configured, so the gateway is not offline.
