You are administering a SQL Server Analysts Services (SSAS) database on a server. The database hosts a financial cube based on a SQL Azure database.
You need to grant write access to the financial cube for all users in the group USA\PowerUsers. Which three actions should you perform in sequence?
(To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
Answer:
Explanation:
Box 1: In the SQL Management Studio (SSMS), connect to the SSAS instance on the server.
Box 2: Create a new role for the database.
Box 3: Add the USA\PowerUsers group to the role. Set the cube access for the role to Read and Process.
Note:
* A member of the server role for Microsoft SQL Server Analysis Services, or a member of a database role that has Full Control (Administrator) permissions in a particular database, can create a database role that only has permission to process specified objects within the database. Giving a database role permission to process a database object lets an administrator delegate the task of processing certain objects, without also granting extraneous permissions to the user who is performing the processing.
* To give a database role permission to process a cube In SQL Server Management Studio, connect to the instance of Analysis Services, expand Roles for the appropriate database in Object Explorer, and then double-click a database role (or right-click Roles and select New Role to create a new database role). If this is a new role, make sure that you enter a name for the role in the Role namebox.
Click Cubes in the Select a Page pane, locate the cube in the Cube list, and then select the Process check box for the cube.
Click the OK button.
* There is no write permissions on a cube.

QUESTION 30
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. What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
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.
