What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

An existing cube dimension that has 30 attribute hierarchies is performing very poorly. You have the
following requirements:
Implement drill-down browsing.
Reduce the number of attribute hierarchies but ensure that the information contained within them is
available to users on demand.
Optimize performance.
You need to redesign the cube dimension to meet the requirements.

A. set the AggregateFunction property to Sum on all measures. Use the SCOPE statement in a
Multidimensional Expressions (MDX) calculation to tune the aggregation types.
B. Set the AttributeHierarchyOptimizedState property to FullyOptimized on the attribute hierarchies.
C. Create user-defined hierarchies. For the attributes sourced by the levels of the user-defined
hierarchies, set the RelationshipType property to Rigid. Run incremental processing.
D. Remove as many attribute hierarchies as possible from the dimension. Reintroduce the information in
the attribute hierarchies as properties. Implement natural hierarchies and set the
AttributeHierarchyVisible property to False for attributes used as levels in the natural hierarchies.
Answer: D
