PL-900 Practice Question: A Power Apps app uses a canvas and connects to…
A Power Apps app uses a canvas and connects to multiple data sources. Users complain that the app loads slowly. What is the best practice to improve performance?
⚠ Common exam trap
A common mix-up: candidates think adding more screens distributes the workload, but in Power Apps, each screen loads independently and can trigger separate data source calls, worsening performance rather than improving it.

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 the 'ClearCollect' function to cache data in a collection
The ClearCollect function allows you to cache data from external sources into a local collection within the app. This reduces the number of round trips to the data source during user interactions, significantly improving load and response times by minimizing network latency and data source throttling.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use the 'ClearCollect' function to cache data in a collection
Why this is correct
Collections cache data locally, reducing repeated queries.
- ✗
Add more screens to distribute the load
Why it's wrong here
More screens don't reduce data calls.
- ✗
Increase the timeout settings
Why it's wrong here
Longer timeout doesn't improve speed.
- ✗
Use a single data source
Why it's wrong here
Not always possible and doesn't guarantee performance.
