You design a Business Intelligence （BI） solution by using SQL Server 2008. You create a SQL Server 2008 Reporting Services （SSRS） solution by using SQL Server 2008. Several reports on the server use a shared data source named DSProduction. You modify an existing report that uses the DSProduction data source. After deployment， the modified report must use an alternate data source. You need to prevent the modified report from affecting other reports. What should you do？（）

A. Update the connection string of the DSProduction shared data source to point to the alternate data source.
B. Update the modified report to use a report-specific data source. Update the connection string of the report-specific data source to point to the alternate data source.
C. Create a new shared data source named DSProduction in the same folder as that of the modified report. Update the connection string of the new shared data source to point to the alternate data source.
D. Disable the DSProduction data source. Update the modified report to use a report-specific data source. Update the connection string of the report-specific data source to point to the alternate data source.

You design a Business Intelligence （BI） solution by using SQL Server 2008. You design a SQL Server 2008 Analysis Services （SSAS） solution. Customer data is stored in the tables named CustomerDetails and CustomerContact. The solution uses the following two data sources from two different servers： ·Contoso that accesses the CustomerDetails table ·ContosoCRM that accesses the CustomerContact table You plan to create a dimension named DimCustomer to analyze customer data. You need to ensure that the DimCustomer dimension represents the tables as a snowflake schema to include attributes from the two tables. What should you do？（）

A. Create a data source view named DsvContoso that is associated with the two data sources and add the tables to the data source view.
B. Create a data source view named DsvContoso that is associated with the two data sources and create a named query in the data source view to merge the tables.
C. Create a data source view named DsvCustomer that is associated with the Contoso data source and add the CustomerDetails table to the data source view.Create a data source view named DsvCustomerContact that is associated with the ContosoCRM data source and add the CustomerContact table to the data source view.
D. Create a data source view named DsvCustomer that is associated with the Contoso data source and create a named query in the data source view to select data from the CustomerDetails table.Create a data source view named DsvCustomerContact that is associated with the ContosoCRM data source and create a named query in the data source view to select data from the CustomerContact table.

單項選擇題

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

單項選擇題

You design a Business Intelligence （BI） solution by using SQL Server 2008. The solution includes a SQL Server 2008 Reporting Services （SSRS） infrastructure in a scale-out deployment. All reports use a SQL Server 2008 relational database as the data source. You implement row-level security. You need to ensure that all reports display only the expected data based on the user who is viewing the report. What should you do？（）

A. Store the credential of a user in the data source.
B. Configure the infrastructure to support Kerberos authentication.
C. Configure the infrastructure to support anonymous authentication by using a custom authentication extension.
D. Ensure that all report queries add a filter that uses the User.UserID value as a hidden parameter.

單項選擇題

You design a Business Intelligence （BI） solution by using SQL Server 2008. The solution includes a SQL Server 2008 Analysis Services （SSAS） database. A cube in the database contains a large dimension named Customers. The database uses a data source that is located on a remote server. Each day， an application adds millions of fact rows and thousands of new customers. Currently， a full process of the cube takes several hours. You need to ensure that queries return the most recent customer data with the minimum amount of latency. Which cube storage model should you use？（）

A. hybrid online analytical processing （HOLAP）
B. relational online analytical processing （ROLAP）
C. multidimensional online analytical processing （MOLAP）
D. automatic multidimensional online analytical processing （automatic MOLAP）
