Correct answer & explanation
✓
Enable soft delete to protect against accidental deletion
Enabling soft delete on Azure Data Lake Storage Gen2 protects against accidental deletion by retaining deleted data for a specified retention period. This allows recovery of blobs or snapshots that were deleted, overwritten, or modified, which is a critical data protection practice for enterprise storage solutions.
