PL-900 Practice Question: Demonstrate the capabilities of Power Automate
A Power Automate flow uses the 'Apply to each' action to process items from a SharePoint list. The flow is running slowly. What is the most effective way 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
✓
Enable concurrency control on the 'Apply to each' action.
Enabling concurrency control on the 'Apply to each' action allows multiple iterations to run in parallel, significantly reducing total processing time. Option A adds a condition inside the loop, which does not improve performance and may even add overhead. Option B replaces the loop with a 'Do until' loop, which still processes items sequentially. Option D reduces the number of items, which is not always feasible and does not improve the flow's efficiency when processing large lists.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add a 'Condition' action inside the loop.
Why it's wrong here
Adding actions may slow it further.
- ✗
Use a 'Do until' loop instead.
Why it's wrong here
Do until is for looping until a condition, not for iterating arrays.
- ✓
Enable concurrency control on the 'Apply to each' action.
Why this is correct
Concurrency processes items in parallel.
- ✗
Reduce the number of items in the list.
Why it's wrong here
Not always feasible.
