You are creating a managed data warehouse solution on Microsoft Azure.
You must use PolyBase to retrieve data from Azure Blob storage that resides in parquet format and load the data into a large table called FactSalesOrderDetails.
You need to configure Azure SQL Data Warehouse to receive the data.

Correct Answer:

Explanation/Reference:
Explanation:
Step 1: Create a master key on the database
Create a master key on the database. This is required to encrypt the credential secret.
Step 2: Create an external data source for Azure Blob storage
Create an external data source with CREATE EXTERNAL DATA SOURCE..
Step 3: Create an external file format to map parquet files.
Create an external file format with CREATE EXTERNAL FILE FORMAT.
FORMAT TYPE: Type of format in Hadoop (DELIMITEDTEXT, RCFILE, ORC, PARQUET).
Step 4: Create the external table FactSalesOrderDetails
To query the data in your Hadoop data source, you must define an external table to use in Transact-SQL queries.
Create an external table pointing to data stored in Azure storage with CREATE EXTERNAL TABLE.
Note: PolyBase is a technology that accesses and combines both non-relational and relational data, all from within SQL Server. It allows you to run queries on external data in Hadoop or Azure blob storage.
