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 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 SQL Server 2008 Integration Services (SSIS) pipeline tasks to schedule periodic cube updates.
B. 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.
C. Use the automatic multidimensional online analytical processing (MOLAP) cube storage model.
D. Use the relational online analytical processing (ROLAP) cube storage model.

Question 2

You design a Business Intelligence (BI) solution by using SQL Server 2008. The solution includes a data
warehouse that has an online transaction processing (OLTP) database as the data source.
The tables in the OLTP database do not include date or time information. On each execution, the SQL
Server 2008 Integration Services (SSIS) package that copies the data must reload and process the entire
dataset.
You plan to improve the process of loading the data warehouse. You need to ensure that the following
requirements are met:
-Only new and modified data is processed.
-All modifications of the rows caused due to insert, update, and delete activities are processed.
-The impact of the loading process on the source system is minimal.
Which action should you perform on the tables that are involved in the load process?

A. Set up the Change Tracking feature.
B. Set up the Change Data Capture (CDC) feature.
C. Create Data Manipulation Language (DML) triggers.
D. Create timestamp columns.

Question 3

You design a Business Intelligence (BI) solution by using SQL Server 2008. At the end of every business
day, an application records the inventory to the Products table. The business solution for the application
must accommodate the following features:
-The content of the Products table varies every day.
-Historical product attributes are not stored.
You need to identify an appropriate dimensional model to meet the business solution. Which model should you use?

A. Type II Slowly Changing Dimension
B. Degenerate Dimension
C. Type I Slowly Changing Dimension
D. ParentChild Dimension

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. Modify the UPDATE statement in the OLE DB Command transform to use the PAGLOCK table hint.
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. 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.

Question 5

You design a SQL Server 2008 Reporting Services (SSRS) solution. You create a report by using Microsoft Visual Studio .NET 2008. The report contains the following components: A dataset named Customer that lists all active customers and their details. The dataset accepts no parameters. A dataset named SalesHistory that lists all sales transactions for a specified time period and accepts year and month as parameters.You need to ensure that a summary of sales transactions is displayed for each customer after the customer details. Which component should you add to the report?

A. List
B. Table
C. Matrix
