You are a database developer and you have about two years experience in creating
business Intelligence (BI) by using SQL Server2008.

Now you are employed in a company named NaproStar which uses SQL Server2008. You
work as the technical support.
Now you receive an e-mail from your company CIO, in the e-mail, the CIO assigns a task to
you.
You use SQL Server 2008 Reporting Services (SSRS) to create a solution.
The solution contains a dimension named DimDay and a measure group named
FinishedSales.
The DimDay dimension contains an attribute which is named Week. The FinishedSales
references the DimDay dimension. According to the requirement of the company CIO, you
must make sure that the aggregations designed on FinishedSales always include the Week
attribute.
So what action should be performed?

A.
You should set the Usage property appropriately

B.
You should set the IsAggregatable property appropriately

C.
You should set the AggregationUsage property appropriately

D.
You should set the AttributeHierarchyEnabled property appropriately

Explanation:
Review Aggregation Usage (Aggregation Design Wizard)
SQL Server 2008 R2 Other Versions Use the Review Aggregation Usage page to configure
aggregation usage settings. Options Default: Select to set the aggregation usage setting for
the attribute to Default. By using this setting, the designer applies a default rule based on the
type of attribute and dimension. Full: Select to set the aggregation usage setting for the
attribute to Full. By using this setting, every aggregation for the cube must include this
attribute or a related attribute that is lower in the attribute chain. The Full aggregation usage
setting should be avoided when an attribute contains many members. If specified for multiple
attributes or attributes that have many members, this setting might prevent aggregations
from being designed because of excessive size. None: Select to set the aggregation usage
setting for the attribute to None. By using this setting, no aggregation for the cube can
include this attribute. Unrestricted: Select to set the aggregation usage setting for the
attribute to Unrestricted. By using this setting, no restrictions are put on the aggregation
designer; however, the attribute must still be evaluated to determine whether it is a valuable
aggregation candidate. Set All to Default: Select to set the aggregation usage settings for all
attributes to Default. The presence of an (All) level in an attribute hierarchy depends on the
IsAggregatable property setting for the attribute and the presence of an (All) level in a userdefined hierarchy depends on the IsAggregatable property of the attribute at the top-most
level of user-defined hierarchy. If the IsAggregatable property is set to True, an (All) level will
exist.
A hierarchy has no (All) level if the IsAggregatable property is set to False.
