You have two Azure Storage accounts named Storage1 and Storage2. Each account holds one container and has the hierarchical namespace enabled. The system has files that contain data stored in the Apache Parquet format.

You need to copy folders and files from Storage1 to Storage2 by using a Data Factory copy activity. The solution must meet the following requirements:

-No transformations must be performed.
-The original folder structure must be retained.
-Minimize time required to perform the copy activity.

How should you configure the copy activity? To answer, select the appropriate options in the answer area.

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: Parquet
For Parquet datasets, the type property of the copy activity source must be set to ParquetSource.

Box 2: PreserveHierarchy
PreserveHierarchy (default): Preserves the file hierarchy in the target folder. The relative path of the source file to the source folder is identical to the relative path of the target file to the target folder.

Incorrect Answers:
FlattenHierarchy: All files from the source folder are in the first level of the target folder. The target files have autogenerated names.
MergeFiles: Merges all files from the source folder to one file. If the file name is specified, the merged file name is the specified name. Otherwise, it's an autogenerated file name.
