Microsoft PRO:MS SQL Server 2008, Designing a Business Intelligence Sample Questions:

1. You design a SQL Server 2008 Analysis Services (SSAS) solution. The solution has dimensions named Account and Scenario. The Scenario dimension has the keys numbered 1 and 2 for the members named Actual and Budget, respectively. The Account dimension has the key numbered 40 for the member named Income. You create a key performance indicator (KPI) named Net Income that has the following parameters: KPI Value: ( [Account].[Accounts].&[40], [Scenario].[Scenario].&[1], [Measures].[Amount] ) KPI Goal: ( [Account].[Accounts].&[40], [Scenario].[Scenario].&[2], [Measures].[Amount] ) If the net income is less than 70 percent of the budgeted value, the performance is considered as bad. If the net income is greater than or equal to 90 percent of the budgeted value, the performance is considered as good. You need to calculate the performance at a specific point in time. What should you do?

A) Set the Trend expression in the KPI to the following code segment: Case When KpiValue( "Net Income" ) / KpiGoal( "Net Income" ) >= .90 Then 1 When KpiValue( "Net Income" ) / KpiGoal( "Net Income" ) < .90 And KpiValue( "Net Income" ) / KpiGoal( "Net Income" ) >= .70 Then 0 Else -1 End
B) Set the Trend expression in the KPI to the following code segment: Case When KpiGoal( "Net Income" ) / KpiValue( "Net Income" ) >= .90 Then 1 When KpiGoal( "Net Income" ) / KpiValue( "Net Income" ) < .90 And KpiGoal( "Net Income" ) / KpiValue( "Net Income" ) >= .70 Then 0 Else -1 End
C) Set the Status expression in the KPI to the following code segment: Case When KpiValue( "Net Income" ) / KpiGoal( "Net Income" ) >= .90 Then 1 When KpiValue( "Net Income" ) / KpiGoal( "Net Income" ) < .90 And KpiValue( "Net Income" ) / KpiGoal( "Net Income" ) >= .70 Then 0 Else -1 End
D) Set the Status expression in the KPI to the following code segment: Case When KpiGoal( "Net Income" ) / KpiValue( "Net Income" ) >= .90 Then 1 When KpiGoal( "Net Income" ) / KpiValue( "Net Income" ) < .90 And KpiGoal( "Net Income" ) / KpiValue( "Net Income" ) >= .70 Then 0 Else -1 End

2. You administer a server that runs SQL Server 2008 Integration Services (SSIS) packages.
The packages are stored on the file system.
You need to integrate the backup and restore processes for the SSIS packages along with the regular SQL
Server backup process.
What should you do?

A) In the ProtectionLevel package property, select the ServerStorage option.
B) Deploy the packages to SQL Server 2008 and back up the master system database.
C) In the ProtectionLevel package property, select the DontSaveSensitive option.
D) Deploy the packages to SQL Server 2008 and back up the msdb system database.

3. You are the administrator of your company network. And now you??re in charge of SQL Server 2008 Analysis Services (SSAS) data mining. You create a data mining solution which collects data from three different operational source systems. You noticed that when the operational source systems are accessed directly, performance problems occur. During the off-duty time, the solution is updated continuously by using current data on a daily basis. What should you do to integrate data for the data mining solution without causing performance problems?

A) You should create Views in SQL Server 2008 to join the tables of all the operational source systems by using Open Rowset queries and build the data mining
B) You should integrate all the operational source systems in a Data Source View of the data mining solution and collect data directly from the operational source
C) You should create Views in SQL Server 2008 to join the tables of all the operational source systems by using Linked Servers and create the data mining solution to
D) You should build a staging area to collect data from all the operational source systems by using SQL Server 2008 Integration Services (SSIS) and build the data

4. You design a Business Intelligence (BI) solution by using SQL Server 2008. The solution includes a SQL Server 2008 Analysis Services (SSAS) database. The database contains a data mining structure that uses a SQL Server 2008 table as a data source. A table named OrderDetails contains detailed information on product sales. The OrderDetails table includes a column named Markup. You build a data mining model by using the Microsoft Decision Trees algorithm. You classify Markup as discretized content. The algorithm produces a large number of branches for Markup and results in low confidence ratings on predictable columns. You need to verify whether the Markup values include inaccurate data. What should you do?

A) Create a data profile by using SQL Server 2008 Integration Services (SSIS).
B) Modify the content type of Markup as Continuous.
C) Create a cube in SSAS. Use OrderDetails as a measure group. Recreate the data mining structure and mining model from the cube data.
D) Create a data mining dimension in the SSAS database from OrderDetails.

5. You design a Business Intelligence (BI) solution by using SQL Server 2008. You create a SQL Server 2008
Integration Services (SSIS) package to perform an extract, transform, and load (ETL) process to load data
to a DimCustomer dimension table that contains 1 million rows.
Your data flow uses the following components:
-A SQL Destination data flow task to insert new customers.
-An OLE DB Command transform that updates existing customers.
On average, 25 percent of existing customer records is updated each night. You need to reduce the
amount of time required to update customer records.
What should you do?

A) Modify the UPDATE statement in the OLE DB Command transform to use the PAGLOCK table hint.
B) Stage the data in the data flow. Replace the UPDATE statement in the OLE DB Command transform with a DELETE statement followed by an INSERT statement.
C) Modify the UPDATE statement in the OLE DB Command transform to use the TABLOCK table hint.
D) Stage the data in the data flow. Replace the OLE DB Command transform in the data flow with an Execute SQL task in the control flow.
