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. The SQL Server 2008 Integration Services (SSIS) developers use a SQL Server 2008 instance as the primary development
environment.
All the SSIS packages contain data connection managers that use SQL Server authentication to extract
data. The packages are saved by using the EncryptAllWithUserKey package protection level.You plan a
package migration strategy from the development environment to a production environment. Migration will
be performed by using an automated script.
You need to ensure that the packages execute without error in the production environment.
What should you do?

A) Create a package configuration for every package that uses a SQL Server table.
B) Create a package configuration for every package that uses an XML configuration file.
C) Export each package and change the package protection level to EncryptSensitiveWithPassword.
D) Export each package and change the package protection level to DontSaveSensitive.

2. You design a SQL Server 2008 Analysis Services (SSAS) solution. The data source view has tables as shown in the exhibit. (Click the Exhibit button.)

The FactInternetSales measure will be queried frequently based on the city and country of the customer. You need to design a cube that will provide optimal performance for queries.
Which design should you choose?

A) Create two dimensions named Customer and Geography from the DimCustomer table and the DimGeography table, respectively. Create an unmaterialized reference relationship between the Geography dimension and the FactInternetSales measure by using the Customer dimension as an intermediate dimension.
B) Create two dimensions named Customer and Geography from the DimCustomer table and the DimGeography table, respectively. Create a materialized reference relationship between the Geography dimension and the FactInternetSales measure by using the Customer dimension as an intermediate dimension.
C) Create a dimension named Customer by joining the DimGeography and DimCustomer tables. Add an attribute relationship from CustomerKey to City and from CustomerKey to Country. Create a regular relationship in the cube between the Customer dimension and the FactInternetSales measure.
D) Create a dimension named Customer by joining the DimGeography and DimCustomer tables. Add an attribute relationship from CustomerKey to City and from City to Country. Create a regular relationship in the cube between the Customer dimension and the FactInternetSales measure.

3. You design a Business Intelligence (BI) solution by using SQL Server 2008. The solution contains a SQL
Server 2008 Analysis Services (SSAS) database. A measure group in the database contains log entries of
manufacturing events. These events include accidents, machine failures, production capacity metrics, and
other activities. You need to implement a data mining model that meets the following requirements:
-Predict the frequency of different event types.
-Identify short-term and long-term patterns.
Which algorithm should the data mining model use?

A) the Microsoft Decision Trees algorithm
B) the Microsoft Logistic Regression algorithm
C) the Microsoft Linear Regression algorithm
D) the Microsoft Time Series algorithm

4. 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 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
C) 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
D) 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

5. You are creating a SQL Server 2008 Reporting Services (SSRS) solution for a company that has offices in
different countries. The company has a data server for each country. Sales data for each country is
persisted in the respective data server for the country. Report developers have only Read access to all data
servers. All data servers have the same schema for the database.
You design an SSRS solution to view sales data.
You need to ensure that users are able to easily switch between sales data for different countries.
What should you do?

A) Implement multiple shared data sources.
B) Implement an embedded data source that has a static connection string.
C) Implement a single shared data source.
D) Implement an embedded data source that has an expression-based connection string.
