HOTSPOT
You are developing a SQL Server Analysis Services (SSAS) cube that contains the data for a running team.
The data warehouse used by the cube contains the time durations of taps run by each runner on the team. The time durations are stored in seconds as an integer.
You need to build the following two measures in the cube:
- A measure named Measure1 that must contain the average time duration of the laps run by each runner. - A measure named Measure2 that must contain the lap-time duration and the name of the runner who ran the fastest lap.
What should you do? To answer, select the appropriate Aggregation Function property for each measure in the answer area.

正解：

A production SQL Server Analysis Services (SSAS) cube is processed daily. The users query products by using a hierarchy named Products from a dimension named Product.
The DimProduct table in the data source view is used as the source of the Product dimension. The table has the following structure.

The Product dimension has three attribute hierarchies:
---
Product
Subcategory
Category
The attributes have the following relationships defined: Product > Subcategory - Category. Each attribute has a key and a name sourced from the related key and name columns in theDimProduct table.
During processing, you receive the following error message: "Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: 'dbo_DimProducf, Column: 'SubCategoryKey', Value: '23'. The attribute is Subcategory'."
You verify that the data is accurate.
You need to ensure that the dimension processes successfully.
What should you do?

• A.Relate the Subcategory and Category attributes directly to the Product attribute.
• B.Remove the Subcategory attribute.
• C.Remove the duplicate data from the DimProduct table.
• D.Delete the Products hierarchy.

You are designing a customer dimension for a multidimensional OLAP (MOLAP) database. The dimension table will contain millions of rows of data.
Customer dimension attributes will come from the following two sources:
- An enterprise resource planning (ERP) system that contains millions of rows of data. Attributes from this source will be updated daily.
- A marketing database that contains thousands of rows of data representing customers' geographic information. Attributes from this source will be updated monthly.
Most report queries against the cube use attributes from both sources. Customers in the
cube dimension will frequently be filtered by the geographic attributes.
You need to design the dimension table and cube dimension to ensure that report queries perform well, and minimize the time required to reprocess cube attributes.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

• A.Create a dimension table for each source, and a cube dimension for each source.
• B.Create one dimension table that combines data from both sources. Create a cube dimension for each source.
• C.Create a dimension table for each source. Create one cube dimension that joins the two dimension tables together.
• D.Create one dimension table that combines data from both sources. Create one cube dimension that references the dimension table.

DRAG DROP
You have a cube named Cube1 that contains the sales data for your company.
You plan to build a report based on the cube.
You need to write an MDX expression that returns the total sales from the first month of the 2009 fiscal year and the total sales from the same period of the 2008 fiscal year.
Which code segments should you insert at line 03 and line 05? To answer, drag the appropriate code segments to the correct lines. Each code segments may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

• A.Clear the Apply compression check box. Select the Encrypt backup file check box and supply a password.
• B.Select the Apply compression check box. Select the Encrypt backup file check box and supply a password.
• C.Clear the Apply compression check box. Clear the Encrypt backup file check box.
• D.Select the Apply compression check box. Clear the Encrypt backup file check box.
