PL-900 Demonstrate the capabilities of Power Apps Practice Question
An app maker creates a canvas app that uses a Dataverse table with 100,000 records. The app includes a gallery that displays all records. Users experience long load times. What should the app maker do to improve performance without changing the data source?
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
✓
Use delegable functions in the gallery's Items property
Using delegable functions (such as Filter, Sort, LookUp) in the gallery's Items property allows the query to be processed on the Dataverse server, returning only the necessary subset of records. This significantly reduces the amount of data transferred and improves performance for large datasets like 100,000 records. Option B is incorrect because it involves changing the data source, which is not allowed per the question. Option C is incorrect because increasing the data row limit in Dataverse settings does not address the delegation issue and may even worsen performance. Option D is incorrect because removing filters would cause the entire dataset to be loaded, making load times even longer.
