since we are querying b MM or year and data is secured by subject area. its better that we design the folder structure that does minimal scan of folder. here in this case we should first create year , month nd then service area

Selected Answer: D

Serverless SQL Pools offers a straight-forward method of querying data including CSV, JSON, and Parquet format stored in Azure Storage. So, setting up the csv files within azure storage in hive-formated folder hierarchy i.e. /{yyyy}/{mm}/{dd}/ actually helps in sql querying the data much faster since only the partitioned segment of the data is queried.
