Microsoft TS:MS SQL Server 2008.Business Intelligence Dev and Maintenan 認定 70-448 試験問題:

1. You create a data mining model by using SQL Server 2008 Analysis Services (SSAS).
You create a mining structure by using the following Data Mining Extensions (DMX) code.
CREATE MINING STRUCTURE [Bike Buyer](
[Customer Key] LONG KEY,
[Age] LONG DISCRETIZED(Automatic, 10),
[Bike Buyer] LONG DISCRETE,
[Commute Distance] TEXT DISCRETE,
[Yearly Income] DOUBLE CONTINUOUS
)
You need to create a mining model that can be processed by using this mining structure. You also need to
ensure that the model uses the Microsoft Decision Trees algorithm.
Which DMX statement should you use?

A) INSERT INTO [Decision Tree] ( [Customer Key], [Age], [Bike Buyer], [Commute Distance], [Yearly Income] ) OPENQUERY([Bike Buyer], ?'Select [Customer Key], [Age], [Bike Buyer] , [Commute Distance],[Yearly Income]' )
B) SELECT * INTO [Decision Tree] USING [Microsoft_Decision_Trees] FROM [Bike Buyer]
C) ALTER MINING STRUCTURE [Bike Buyer] ADD MINING MODEL [Decision Tree] ( [Customer Key],
[Age],
[Bike Buyer] PREDICT,
[Commute Distance],
[Yearly Income]
)?USING Microsoft_Decision_Trees
WITH DRILLTHROUGH
D) CREATE MINING MODEL [Decision Tree] ( [Customer Key] LONG KEY, [Age] LONG DISCRETIZED(Automatic, 10), [Bike Buyer] LONG DISCRETE, [Commute Distance] TEXT DISCRETE, [Yearly Income] DOUBLE CONTINUOUS )?USING Microsoft_Decision_Trees

2. You create a SQL Server 2008 Analysis Services (SSAS) solution. You have a dimension named Account and a time dimension named Time. You have a fact table that contains a column named CurrentBalance. CurrentBalance contains the current account balance. You need to create a measure named AccountBalance from the CurrentBalance column to display the closing account balance for a time period. What should you do?

A) Set the AggregationFunction property of AccountBalance to FirstNonEmpty.
B) Set the AggregationFunction property of AccountBalance to ByAccount.
C) Set the AggregationFunction property of AccountBalance to LastNonEmpty.
D) Set the AggregationFunction property of AccountBalance to Sum.

3. You maintain a SQL Server 2008 Analysis Services (SSAS) database on a default instance.
You plan to document the Analysis Services performance information.
You need to collect information related to cache hits from the memory when the database is processed.
Which object should you use?

A) MSAS 2008: Memory
B) MSAS 2008: Proc Aggregations
C) MSAS 2008: Storage Engine Query
D) MSAS 2008: Cache

4. Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You maintain a SQL Server 2008 Reporting Services (SSRS) instance for a shoe company.
An existing report on shoe sales allows the user to see the company's revenue across many different
attributes.
You need to create a drop down list that filters the report by one or more shoe colors.
You alter the main dataset and configure the report parameter to accept multiple values.
What should you do next?

A) Configure the Internal Visibility option for the parameter.
B) Create a dynamic data source from a dataset that includes a list of distinct servers.
C) Configure the Hidden Visibility property.
D) Create a dynamic dataset that utilizes the WHERE clause to filter by the parameter.
E) Create a distinct dataset that includes all possible values and attach it to the parameter.
F) Create a dynamic data source from a dataset by using the IN operator.
G) Develop a report for each environment.
H) Create a dynamic dataset that includes a list of the different users.

5. You administer a SQL Server 2008 Analysis Services (SSAS) database. A sales manager is responsible for the sales of bikes in the Northeast region. You plan to grant the necessary permissions to the sales manager to access the database. You have two roles named Northeast Region and Bikes. The schemas of the two roles are as shown in the following tablE.Role Allowed set
Northeast Region
{[Sales Territory].[Sales Territory Region].&[Northeast]}
Bikes
{[Product].[Product Category].[Product Category].&[Bikes]}
The Visual Totals property is set to True for both roles.
You need to ensure that the sales manager can view only the members in the Product dimension that relate
to the Bikes category in the Northeast region.
What should you do?

A) Add the manager to a new role that has the following two components: {[Sales Territory].[Sales Territory Region].&[Northeast]} as the allowed set. {[Product].[Product Category].[Product Category].&[Bikes]} as the allowed set.
B) Add the manager to the Northeast Region role.
C) Add the manager to a new role that has the following two components: {[Sales Territory].[Sales Territory Region].AllMembers} as the denied set {[Sales Territory].[Sales Territory Region].&[Northeast]} as the allowed set. {[Product].[Product Category].[Product Category].AllMembers} as the denied set. {[Product].[Product Category].[Product Category].&[Bikes]} as the allowed set.
D) Add the manager to the Bikes role.
