Microsoft DP-203 Data Engineering on Microsoft Azure Exam Practice Test

You have an Azure Data Factory pipeline named Pipeline1!. Pipelinel contains a copy activity that sends data to an Azure Data Lake Storage Gen2 account. Pipeline 1 is executed by a schedule trigger.

You change the copy activity sink to a new storage account and merge the changes into the collaboration branch.

After Pipelinel executes, you discover that data is NOT copied to the new storage account.

You need to ensure that the data is copied to the new storage account.

What should you do?

You have an Azure Synapse Analytics dedicated SQL pool named pool1.

You plan to implement a star schema in pool1 and create a new table named DimCustomer by using the following code.

You need to ensure that DimCustomer has the necessary columns to support a Type 2 slowly changing dimension (SCD). Which two columns should you add? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

You are designing a folder structure for the files m an Azure Data Lake Storage Gen2 account. The account has one container that contains three years of data.

You need to recommend a folder structure that meets the following requirements:

* Supports partition elimination for queries by Azure Synapse Analytics serverless SQL pooh

* Supports fast data retrieval for data from the current month

* Simplifies data security management by department

Which folder structure should you recommend?

You have an Azure Data Lake Storage Gen2 account that contains two folders named Folder and Folder2.

You use Azure Data Factory to copy multiple files from Folder1 to Folder2.

You receive the following error.

What should you do to resolve the error.

You are implementing a star schema in an Azure Synapse Analytics dedicated SQL pool.

You plan to create a table named DimProduct.

DimProduct must be a Type 3 slowly changing dimension (SCO) table that meets the following requirements:

* The values in two columns named ProductKey and ProductSourceID will remain the same.

* The values in three columns named ProductName, ProductDescription, and Color can change.

You need to add additional columns to complete the following table definition.

A)

B)

C)

D)

E)

F)

You have an Azure Synapse Analytics dedicated SQL pool.

You need to Create a fact table named Table1 that will store sales data from the last three years. The solution must be optimized for the following query operations:

Show order counts by week.

* Calculate sales totals by region.

* Calculate sales totals by product.

* Find all the orders from a given month.

Which data should you use to partition Table1?

You haw an Azure data factory named ADF1.

You currently publish all pipeline authoring changes directly to ADF1.

You need to implement version control for the changes made to pipeline artifacts. The solution must ensure that you can apply version control to the resources currently defined m the UX Authoring canvas for ADF1.

Which two actions should you perform? Each correct answer presents part of the solution

NOTE: Each correct selection is worth one point.
