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

1. You design a Business Intelligence (BI) solution by using SQL Server 2008. You have a SQL Server 2008 Integration Services (SSIS) package that runs against a SQL Server 2008 data source. The package contains an opening Execute SQL task that runs the BEGIN TRANSACTION command. This is followed by a Sequence task that contains additional Execute SQL tasks, each with the FailParentOnFailure property set to TRUE . There are two Execute SQL tasks. The first task is connected to a Success precedence constraint that runs the COMMIT TRANSACTION command. The next task is connected to a Failure precedence constraint that runs the ROLLBACK TRANSACTION command. The package fails but the transaction is not rolled back. You need to ensure that the transaction is successfully rolled back if the package fails. What should you do?

A) Modify the RetainSameConnection property as True for the Connection Object.
B) Modify the IsolationLevel property as ReadCommitted for each Execute SQL task.
C) Modify the TransactionOption property as Required for each Execute SQL task.
D) Modify the TransactionOption property as Required for the Sequence Container.

2. You design a Business Intelligence (BI) solution by using SQL Server 2008. You plan to develop SQL Server 2008 Reporting Services (SSRS) reports. Several reports will contain identical data regions. You need to minimize the amount of maintenance when changes are made to the data regions. What should you do?

A) Grant the Create Linked Reports role to all users.
B) Create a shared data source in the SSRS project. Use the new shared data source for all reports.
C) Create a report template for each data region. Use the report template to create each report.
D) Create each data region as a report. Embed the reports by using the subreport control.

3. You design a SQL Server 2008 Analysis Services (SSAS) solution. Your solution has a measure named
Sales Amount and a dimension named Date. The Date dimension has a hierarchy named Fiscal that has
levels named Fiscal Year, Fiscal Quarter, and Fiscal Month.
You need to create a calculated member to analyze the Sales Amount share percentage at different levels
compared to the total sales for a given Fiscal Year.
Which code segment should you use?

A) Case When [Date].[Fiscal].CurrentMember.Level.Ordinal = 0 Then 1 Else [Measures].[Sales Amount]/([Measures].[Sales Amount], Ancestor([Date].[Fiscal].CurrentMember, [Date].[Fiscal].[Fiscal Year])) End
B) Case When [Date].[Fiscal].CurrentMember.Level.Ordinal = 0 Then 1 Else [Measures].[Sales Amount]/([Measures].[Sales Amount], [Date].[Fiscal].CurrentMember.Parent) End
C) Case When [Date].[Fiscal].CurrentMember.Level.Ordinal = 0 Then 1 Else [Measures].[Sales Amount]/([Measures].[Sales Amount], [Date].[Fiscal].[Fiscal Year].CurrentMember) End
D) Case When [Date].[Fiscal].CurrentMember.Level.Ordinal = 0 Then 1 Else [Measures].[Sales Amount]/([Measures].[Sales Amount], Descendants([Date].[Fiscal].CurrentMember, [Date].[Fiscal].[Fiscal Year], SELF_AND_AFTER)) End

4. You are the administrator of your company network. You use SQL Server 2008 to develop a Business Intelligence (BI) solution. All transaction data of your company is processed in a Point of Sale (POS) application. You work out a solution on the basis of the transaction data, in order to foretell which type of products a customer may buy on a single visit. You have to select the suitable algorithm to design the solution. So which algorithm should you choose?

A) You should use Association Rules
B) You should use Naive Bayes
C) You should use Time Series
D) You should use Clustering

5. You design a Business Intelligence (BI) solution by using SQL Server 2008. You plan to design a logging strategy for a SQL Server 2008 Integration Services (SSIS) solution. The SSIS solution contains 15 packages. You want to log detailed information about each package. You need to ensure that custom events specific to each control flow task in each package are logged. What should you do?

A) Create a custom assembly that writes to the log, and use the assembly in a Script task. Ensure that the Script task is connected to the appropriate control flow task by using a Failure precedence constraint.
B) Configure logging for each control flow task in each package for the required events.
C) Enable the Log Events window in Business Intelligence Development Studio (BIDS) that has the SSIS solution loaded.
D) Enable event handling for each control flow task in each package for the required events. Create custom code to perform the logging by using a Script component.
