Microsoft PRO:MS SQL Server 2008, Designing a Business Intelligence Sample Questions:
Question 1
You design a Business Intelligence (BI) solution by using SQL Server 2008. You create a SQL Server 2008
Reporting Services (SSRS) report.
The report contains summary information in two sections named Agencies and States. The Agency
summary section contains two matrices and the State summary section contains a table. The information
about each section is grouped together.
You need to design the report to meet the following requirements:
-When the report is exported to a Microsoft Excel spreadsheet, each summary section is rendered to a
separate tab.
-The structure in each section is retained.
What should you do?
A. Select a line component between the report items for the Agency and State summary sections.
B. Select all the report items for each section in a rectangle report item and enable the Add A Page Break Before option on the rectangle report item.
C. Select all the report items for each section in a list report item and enable the Add A Page Break Before option on the list report item.
D. Select the Keep together on one page option on all report items.
Question 2
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 hybrid online analytical processing (HOLAP) cube storage model. Use SQL Server 2008 Integration Services (SSIS) pipeline tasks to schedule periodic cube updates.
C. Use the relational online analytical processing (ROLAP) cube storage model.
D. Use the automatic multidimensional online analytical processing (MOLAP) cube storage model.
Question 3
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 cube in SSAS. Use OrderDetails as a measure group. Recreate the data mining structure and mining model from the cube data.
B. Modify the content type of Markup as Continuous.
C. Create a data mining dimension in the SSAS database from OrderDetails.
D. Create a data profile by using SQL Server 2008 Integration Services (SSIS).
Question 4
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. 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.
B. 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.
C. Modify the UPDATE statement in the OLE DB Command transform to use the TABLOCK table hint.
D. Modify the UPDATE statement in the OLE DB Command transform to use the PAGLOCK table hint.
Question 5
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. Create a data source view named DsvCustomerContact that is associated with the ContosoCRM data source and add the CustomerContact table to
B. 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
C. 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
D. Create a data source view named DsvCustomerContact that is associated with the ContosoCRM data source and
E. 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
F. 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.
