Microsoft PRO:MS SQL Server 2008, Designing a Business Intelligence Sample Questions:
1. You are the administrator of your company network. You use Server 2008 to develop a Business Intelligence (BI) solution. And you want to deploy a new database that contains a cube to the SQL Server 2008 Analysis Services (SSAS) instance. And the cube contains three Type 1 slowly hanging dimensions. The database is updated everyday by adding 4,800 rows of data every hour. Now you have to make sure two things, one is the cube must contain up-to-date data at all times, the other is, during cube processing, the users are able to access the cube. So what should you do to achieve this two?
A) You should utilize the hybrid online analytical processing (HOLAP) cube storage model. Use SQL Server 2008 Integration Services (SSIS) pipeline tasks to
B) You should utilize the automatic multidimensional online analytical processing (MOLAP) cube storage model.
C) You should utilize the hybrid online analytical processing (HOLAP) cube storage model. Use the snapshot isolation level in the relational database that the cube is
D) You should utilize the relational online analytical processing (ROLAP) cube storage model.
2. 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
3. You design a SQL Server 2008 Analysis Services (SSAS) solution. The solution includes a mining structure that is created by using the default options and a mining model that uses the Microsoft Clustering algorithm. You need to ensure that users can access source data by querying the mining model. What should you do?
A) Include a task in the solution to delete all cached data from the mining model.
B) Modify the mining structure to include a filter.
C) Modify the mining structure to enable drillthrough.
D) Include a task in the solution to process the mining model.
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 Analysis Services (SSAS) solution by using SQL Server 2008. The solution contains a dimension named DimCustomer that represents customers. The solution provides a list of top 10 customers based on the sales amount. End users of the solution analyze data by using filters in Microsoft Excel worksheet. You need to ensure that the list is updated when the filters are applied. Which named set expression should you use?
A) CREATE HIDDEN SET CURRENTCUBE.[Top 10 Customer] AS TOPCOUNT([DimCustomer].[Customer].MEMBERS,10,[Measures].[SalesAmount])
B) CREATE SET CURRENTCUBE.[Top 10 Customer] AS TOPCOUNT([DimCustomer].[Customer].MEMBERS,10,[Measures].[SalesAmount])
C) CREATE DYNAMIC SET CURRENTCUBE.[Top 10 Customer] AS TOPCOUNT([DimCustomer].[Customer].MEMBERS,10,[Measures].[SalesAmount])
D) CREATE SESSION SET CURRENTCUBE.[Top 10 Customer] AS TOPCOUNT([DimCustomer].[Customer].MEMBERS,10,[Measures].[SalesAmount])
