PL-900 Demonstrate the capabilities of Power Apps Practice Question
You are troubleshooting a canvas app that loads slowly. The app uses over 50 data sources and many formulas. Which action is most likely to improve performance?
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 queries to filter data at the source
Delegable queries process filtering on the data source server, reducing the amount of data transferred to the app and improving load time. Option A is incorrect because increasing the data row limit can actually increase the amount of data loaded, worsening performance. Option C is incorrect because disabling formula-level error checking does not affect performance and can hide issues. Option D is incorrect because removing unused data sources helps reduce app size but may not be the most impactful action for slow loading due to excessive data retrieval.

Increase the data row limit for each data source
Why it's wrong here
Increasing row limit can slow performance.
- ✓
Use delegable queries to filter data at the source
Why this is correct
Delegation pushes filtering to the data source, reducing data transfer.
- ✗
Disable the formula-level error checking
Why it's wrong here
Error checking does not impact app performance.
- ✗
Remove unused data sources from the app
Why it's wrong here
Unused data sources do not affect runtime performance.
