Microsoft PRO:MS SQL Server 2008, Designing a Business Intelligence 認定 70-452 試験問題:

1. You design a SQL Server 2008 Analysis Services (SSAS) solution. Your solution has a measure named
Sales Amount and a dimension named Date. The Date dimension has a hierarchy named Fiscal that has
levels named Fiscal Year, Fiscal Quarter, and Fiscal Month.
You need to create a calculated member to analyze the Sales Amount share percentage at different levels
compared to the total sales for a given Fiscal Year.
Which code segment should you use?

A) Case When [Date].[Fiscal].CurrentMember.Level.Ordinal = 0 Then 1 Else [Measures].[Sales Amount]/([Measures].[Sales Amount], Descendants([Date].[Fiscal].CurrentMember, [Date].[Fiscal].[Fiscal Year], SELF_AND_AFTER)) End
B) Case When [Date].[Fiscal].CurrentMember.Level.Ordinal = 0 Then 1 Else [Measures].[Sales Amount]/([Measures].[Sales Amount], [Date].[Fiscal].[Fiscal Year].CurrentMember) End
C) Case When [Date].[Fiscal].CurrentMember.Level.Ordinal = 0 Then 1 Else [Measures].[Sales Amount]/([Measures].[Sales Amount], [Date].[Fiscal].CurrentMember.Parent) End
D) Case When [Date].[Fiscal].CurrentMember.Level.Ordinal = 0 Then 1 Else [Measures].[Sales Amount]/([Measures].[Sales Amount], Ancestor([Date].[Fiscal].CurrentMember, [Date].[Fiscal].[Fiscal Year])) End

2. You are the administrator of your company network. You use SQL Server 2008 to develop a Business Intelligence (BI) solution. You create a SQL Server 2008 Reporting Services (SSRS) solution which has a report named SellDetails. The report contains a parameter named WorkerID. You have the following constraints: Eight thousand employees need the report to be in different file formats.The employees can view only their sales data by specifying their identity number as the EmployeeID parameter. You have to make sure that before you deliver the report to the workers, the constraints are met. So what should you do?

A) You should create a data-driven subscription.
B) You should create a report model for each employee.
C) You should create a subscription for each employee.
D) You should create a SharePoint Report Center site.

3. 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 a materialized reference relationship between the Geography dimension and the FactInternetSales measure by using the Customer dimension as an intermediate dimension.
B) 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.
C) 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.
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.

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) 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.
D) Modify the UPDATE statement in the OLE DB Command transform to use the TABLOCK table hint.

5. You are the administrator of your company network. You use SQL Server 2008 to develop a Business Intelligence (BI) solution. You work out a SQL Server 2008 Analysis Services (SSAS) solution which includes a cube that has a cube that has a measure named SellAmount. Customer sales data for the last five months is stored in the measure. The cube has a single partition which has the storage property set to real-time hybrid online analytical processing (HOLAP). Queries against the cube must return current sales data that is entered one hour before cube processing. The partition takes more than two hours to process and the queries make response slowly. So what should you do to improve the cube processing and query response time?

A) You should modify the storage setting of the partition to multidimensional online analytical processing (MOLAP).
B) You should create a partition for each customer and set the storage setting of every partition to low-latency multidimensional online analytical processing
C) You should modify the storage setting of the partition to real-time relational online analytical processing (ROLAP).
D) You should create a partition for every month and set the storage setting of the partition for the current month to low-latency multidimensional online analytical
