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. You work out a SQL Server 2008 Analysis Services (SSAS) solution. Customer data is stored in the tables named CustomerContact and CustomerDetails. The solution utilizes the following two data sources from two different servers: ContosoCRM that accesses the CustomerContact table Contoso that accesses the CustomerDetails tableYou intend to create a dimension named DimCustomer that analyzes customer data. You have to make sure that the DimCustomer dimension represents the tables as a snowflake schema to include attributes from the two tables. So what should you do to ensure this?

A) You should create a data source view named DsvCustomer which is associated with the
Contoso data source and create a named query in the data source view to
B) You should create a data source view named DsvContoso which is associated with the two data sources and add the tables to the data source view.
C) Create a data source view named DsvCustomerContact that is associated with the ContosoCRM data source and add the CustomerContact table to
D) You should create a data source view named DsvCustomer which is associated with the Contoso data source and add the CustomerDetails table to the data
E) Create a data source view named DsvCustomerContact that is associated with the ContosoCRM data source and
F) You should create a data source view named DsvContoso which is associated with the two data sources and create a named query in the data source view to

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

3. You are the administrator of your company network. You use SQL Server 2008 to develop a Business Intelligence (BI) solution. You use SQL Server 2008 to work out a SQL Server 2008 Analysis Services (SSAS) solution. A source database which contains a table named Client is tilized in the solution. And the Client table contains lots ofcolumns. You have read-only access to the database. You intend to cut down the number of columns in the Client table. You have to split the Client table to be distributed across multiple table definitions. So what should you do?

A) You should create multiple named queries for the SSAS solution.
B) You should create multiple database views for the source database.
C) You should create multiple data sources for the SSAS solution.
D) You should create multiple data source views for the SSAS solution.

4. You design a Business Intelligence (BI) solution by using SQL Server 2008. Several developers work on a
large SQL Server 2008 Analysis Services (SSAS) project. Developers will work in parallel on the same
cubes in the solution.
You need to manage the cube definitions to ensure that each developer's work is not overwritten. You
also need to ensure that conflicts can be easily resolved.
What should you recommend the developers to do?

A) Work in online mode against a local server and synchronize the SSAS database with a shared server frequently.
B) Work in disconnected mode and check in the project to a source control system frequently.
C) Work in online mode against a shared server.
D) Work in disconnected mode and deploy the solution to a shared server frequently.

5. You design a Business Intelligence (BI) solution by using SQL Server 2008. You plan to deploy a new
database to the SQL Server 2008 Analysis Services (SSAS) instance. The database contains a cube. The
cube contains three Type 1 slowly changing dimensions. The database is updated throughout the day by
adding 5,000 rows of data every hour. You need to ensure that the cube always contains up-to-date data.
You also need to ensure that the users can access the cube during cube processing.
What should you do?

A) Use the hybrid online analytical processing (HOLAP) cube storage model. Use the snapshot isolation level in the relational database that the cube is built on.
B) Use the automatic multidimensional online analytical processing (MOLAP) cube storage model.
C) Use the relational online analytical processing (ROLAP) cube storage model.
D) Use the hybrid online analytical processing (HOLAP) cube storage model. Use SQL Server 2008 Integration Services (SSIS) pipeline tasks to schedule periodic cube updates.
