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?
  1. Yes
  2. 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/

  • Create a new row in the data warehouse Products table with the new ReferenceNr value. 
Does the solution meet the goal?
  1. Yes
  2. No
Correct answer: B

Question 6
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You have a Microsoft SQL Server data warehouse instance that supports several client applications. 
The data warehouse includes the following tables: Dimension.SalesTerritory, Dimension.Customer, Dimension.Date, Fact.Ticket, and Fact.Order. The Dimension.SalesTerritory and Dimension.Customer tables are frequently updated. The Fact.Order table is optimized for weekly reporting, but the company wants to change it to daily. The Fact.Order table is loaded by using an ETL process. Indexes have been added to the table over time, but the presence of these indexes slows data loading.
All data in the data warehouse is stored on a shared SAN. All tables are in a database named DB1. You have a second database named DB2 that contains copies of production data for a development environment. The data warehouse has grown and the cost of storage has increased. Data older than one year is accessed infrequently and is considered historical. 
You have the following requirements:
  • Implement table partitioning to improve the manageability of the data warehouse and to avoid the need to repopulate all transactional data each night. Use a partitioning strategy that is as granular as possible. 
  • Partition the Fact.Order table and retain a total of seven years of data. 
  • Partition the Fact.Ticket table and retain seven years of data. At the end of each month, the partition structure must apply a sliding window strategy to ensure that a new partition is available for the upcoming month, and that the oldest month of data is archived and removed. 
  • Optimize data loading for the Dimension.SalesTerritory, Dimension.Customer, and Dimension.Date tables. 
  • Incrementally load all tables in the database and ensure that all incremental changes are processed. 
  • Maximize the performance during the data loading process for the Fact.Order partition. 
  • Ensure that historical data remains online and available for querying. 
  • Reduce ongoing storage costs while maintaining query performance for current data. 
You are not permitted to make changes to the client applications. 
You need to implement partitioning for the Fact.Ticket table. 
Which three actions should you perform in sequence? To answer, drag the appropriate actions to the correct locations. Each action may be used once, more than once or not at all. You may need to drag the split bar between panes or scroll to view content. 
NOTE: More than one combination of answer choices is correct. You will receive credit for any of the correct combinations you select.
Correct answer: To work with this question, an Exam Simulator is required.

Question 7
You manage an inventory system that has a table named Products. The Products table has several hundred columns. 
You generate a report that relates two columns named ProductReference and ProductName from the Products table. The result is sorted by a column named QuantityInStock from largest to smallest. 
You need to create an index that the report can use. 
How should you complete the Transact-SQL statement? To answer, select the appropriate Transact-SQL segments in the answer area.
Correct answer: To work with this question, an Exam Simulator is required.
Question 8
Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You are a database administrator for an e-commerce company that runs an online store. The company has three databases as described in the following table. 
  
  
You plan to load at least one million rows of data each night from DB1 into the OnlineOrder table. You must load data into the correct partitions using a parallel process. 
You create 24 Data Flow tasks. You must place the tasks into a component to allow parallel load. After all of the load processes compete, the process must proceed to the next task.

What should you use?
  1. Lookup transformation
  2. Merge transformation
  3. Merge Join transformation
  4. MERGE statement
  5. Union All transformation
  6. Balanced Data Distributor transformation
  7. Sequential container
