Microsoft TS:MS SQL Server 2008.Business Intelligence Dev and Maintenan Sample Questions:

1. You are working as an ETL developer for a payroll company. You configure a SQL Server 2008 Integration Services (SSIS) package to use checkpoints.
The SSIS package truncates the dbo.Employee_Attendance table, loads the new employees in the dbo.Employee table, and then loads dbo.Employee_Attendance for a particular month.
The control flow for the package is shown in the Control Flow exhibit. (Click the Exhibit button.)
The data flow for the package is shown in the Data Flow exhibit. (Click the Exhibit button.)
The package fails at the Derived Column transformation within the data flow task.
You need to determine where the package execution will begin after you correct the errors and run the package again.
Where does the package execution begin?

A) Load Employee in the Data Flow task.
B) Truncate Employee_ Attendance table in the Execute SQL task
C) Load Emp_Attendance in the Data Flow task.
D) Derived Column Transformation in the data Flow task

2. You develop a SQL Server 2008 Integration Services (SSIS) project. You receive information on sales leads from the sales department. These leads are contained in Microsoft Excel files. You have to load these leads on a daily basis by designing, configuring, deploying, and scheduling steps.
Because this is a daily task, loading Excel files with the Import and Export Data (32-bit or 64-bit) wizard is NOT an option.
When designing the SSIS package, you receive the error shown below and in the Exhibit. (Click the Exhibit button.)
Error: SSIS Error Code DTS_E_OLEDB_EXCEL_NOT_SUPPORTED: The Excel Connection Manager is not supported in the 64-bit version of SSIS, as no OLE DB provider is available.
You need to resolve the error.
Which change should you make to the debug options?

A) Set Run64BitRuntime to False.
B) Set RunInOptimizedmode to False.
C) Set Run64BitRuntime to True.
D) Set RunInOptimizedmode to True.

3. You create a data mining model by using SQL Server 2008 Analysis Services (SSAS).
You create a mining structure by using the following Data Mining Extensions (DMX) code.
CREATE MINING STRUCTURE [Bike Buyer](
[Customer Key] LONG KEY,
[Age] LONG DISCRETIZED(Automatic, 10),
[Bike Buyer] LONG DISCRETE,
[Commute Distance] TEXT DISCRETE,
[Yearly Income] DOUBLE CONTINUOUS
)
You need to create a mining model that can be processed by using this mining structure. You also need to
ensure that the model uses the Microsoft Decision Trees algorithm.
Which DMX statement should you use?

A) INSERT INTO [Decision Tree] ( [Customer Key], [Age], [Bike Buyer], [Commute Distance], [Yearly Income] ) OPENQUERY([Bike Buyer], ?'Select [Customer Key], [Age], [Bike Buyer] , [Commute Distance],[Yearly Income]' )
B) SELECT * INTO [Decision Tree] USING [Microsoft_Decision_Trees] FROM [Bike Buyer]
C) ALTER MINING STRUCTURE [Bike Buyer] ADD MINING MODEL [Decision Tree] ( [Customer Key],
[Age],
[Bike Buyer] PREDICT,
[Commute Distance],
[Yearly Income]
)?USING Microsoft_Decision_Trees
WITH DRILLTHROUGH
D) CREATE MINING MODEL [Decision Tree] ( [Customer Key] LONG KEY, [Age] LONG DISCRETIZED(Automatic, 10), [Bike Buyer] LONG DISCRETE, [Commute Distance] TEXT DISCRETE, [Yearly Income] DOUBLE CONTINUOUS )?USING Microsoft_Decision_Trees

4. You maintain a SQL Server 2008 Reporting Services (SSRS) instance.
