Demo Questions
Question 1
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have the following line-of-business solutions:
- ERP system
- Online WebStore
- Partner extranet
One or more Microsoft SQL Server instances support each solution. Each solution has its own product catalog. You have an additional server that hosts SQL Server Integration Services (SSIS) and a data warehouse. You populate the data warehouse with data from each of the line-of-business solutions. The data warehouse does not store primary key values from the individual source tables.
The database for each solution has a table named Products that stored product information. The Products table in each database uses a separate and unique key for product records. Each table shares a column named ReferenceNr between the databases. This column is used to create queries that involve more than once solution.
You need to load data from the individual solutions into the data warehouse nightly. The following requirements must be met:
- If a change is made to the ReferenceNr column in any of the sources, set the value of IsDisabled to True and create a new row in the Products table.
- If a row is deleted in any of the sources, set the value of IsDisabled to True in the data warehouse.
Solution: Perform the following actions:
- Enable the Change Tracking feature for the Products table in the three source databases.
- Query the CHANGETABLE function from the sources for the deleted rows.
- Set the IsDIsabled column to True on the data warehouse Products table for the listed rows.
Does the solution meet the goal?
- Yes
- No
Correct answer: B
Explanation:
We must check for updated rows, not just deleted rows. References: https://www.timmitchell.net/post/2016/01/18/getting-started-with-change-tracking-in-sql-server/ We must check for updated rows, not just deleted rows.

Solution: Perform the following actions:
- Enable the Change Tracking for the Product table in the source databases.
- Query the cdc.fn_cdc_get_all_changes_capture_dbo_products function from the sources for updated rows.
- Set the IsDisabled column to True for rows with the old ReferenceNr value.
- Create a new row in the data warehouse Products table with the new ReferenceNr value.
Does the solution meet the goal?
- Yes
- No
Correct answer: B
Explanation:
We must also handle the deleted rows, not just the updated rows. References: https://solutioncenter.apexsql.com/enable-use-sql-server-change-data-capture/ We must also handle the deleted rows, not just the updated rows.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are developing a Microsoft SQL Server Integration Services (SSIS) projects. The project consists of several packages that load data warehouse tables.
You need to extend the control flow design for each package to use the following control flow while minimizing development efforts and maintenance:
Solution: You add the control flow to a script task. You add an instance of the script task to the storage account in Microsoft Azure.
Does the solution meet the goal?
- Yes
- No
Correct answer: B
Explanation:
A package consists of a control flow and, optionally, one or more data flows. You create the control flow in a package by using the Control Flow tab in SSIS Designer.
