D. Matching Policy
Answer: A
Q8. You are developing a SQL Server Integration Services (SSIS) package. The data source for the data flow task is a table that has been configured as a change data capture (CDC) table. You are using a CDC Source component to obtain the CDC data.
The data source will be polled once per hour. The data is updated with multiple important status changes per minute.
For each captured data change, the before and after values must be included.
You need to configure the CDC Source component.
Which CDC processing mode should you select? (To answer, configure the appropriate option in the dialog box in the answer area.)
Answer:
Q9. You administer a Microsoft SQL Server 2012 database. The database contains a table named Employee. Part of the Employee table is shown in the exhibit. (Click the Exhibit button.)
Confidential information about the employees is stored in a separate table named EmployeeData. One record exists within EmployeeData for each record in the Employee table. You need to assign the appropriate constraints and table properties to ensure data integrity and visibility. On which column in the Employee table should you use an identity specification to include a seed of 1,000 and an increment of 1?
A. DateHired
B. DepartmentID
C. EmployeeID
D. EmployeeNum
E. FirstName
F. JobTitle
G. LastName
H. MiddleName
I. ReportsToID
Answer: C
Q10. You are editing a SQL Server Integration Services (SSIS) package.
You need to edit the Script task that has an expression defined.
Which task should you select? To answer, select the appropriate setting or settings in the answer area.
Answer:
Q11. You are reviewing the design of an existing fact table named factSales, which is loaded incrementally from a SQL Azure database by a SQL Server Integration Services (SSIS) package each hour. The fact table has approximately 4 billion rows and is dimensioned by product, sales date, and sales time of day.
The database administrator is concerned about the rapid growth of the database and users experience poor reporting performance against this database. Reporting requirements have recently changed and the only remaining report that uses this fact table reports sales by product name, sale month, and sale year. No other reports will be created against this table.
You need to reduce the report processing time and minimize the growth of the database.
What should you do?
A. Create an indexed view over the fact table to sum orderTotal by month.
B. Create a view over the fact table to sum orderTotal by month.
C. Change the granularity of the fact table to month.
D. Partition the fact table by productKey.
Answer: B
Q12. You are developing a SQL Server Integration Services (SSIS) package.
The package sources data from an HTML web page that lists product stock levels.
You need to implement a data flow task that reads the product stock levels from the HTML web page.
Which data flow source should you use?
A. Use an msi file to deploy the package on the server.
B. Open a command prompt and run the dtutil /copy command.
C. Add an OnError event handler to the SSIS project.
D. Open a command prompt and run the gacutil command.
Answer: B
Q13. You are designing an Extract, Transform and Load (ETL) solution that loads data into dimension tables. The ETL process involves many transformation steps.
