}You are reviewing an Azure Data Factory pipeline JSON. Based on the exhibit, what will be the behavior of the Copy activity when copying files from a source folder that contains subfolders?
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
✓
All files from all subfolders will be copied into a single folder in the sink.
The Copy activity is configured with recursive: true, which copies all files from all subfolders, and the sink is set to FlattenHierarchy, which places all files into a single folder without preserving the source folder structure. Option A is incorrect because staging is disabled. Option B is incorrect because recursive: true causes files from subfolders to be copied. Option C is incorrect because FlattenHierarchy does not preserve folder structure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The copy will use staging to improve performance.
Why it's wrong here
enableStaging is false.
- ✗
Only files in the root folder will be copied.
Why it's wrong here
recursive: true includes subfolders.
- ✗
Files will be copied preserving the source folder structure.
Why it's wrong here
FlattenHierarchy does not preserve structure.
- ✓
All files from all subfolders will be copied into a single folder in the sink.
Why this is correct
