QUESTION 51

 

You are reviewing the design of an existing fact table named factSales, which is loaded from a SQL Azure database by a SQL Server Integration Services (SSIS) package each day. The fact table has approximately 1 billion rows and is dimensioned by product, sales date, and sales time of day

The database administrator is concerned about the growth of the database. Users report poor reporting performance against this database. Reporting requirements have recently changed and the only remaining report that uses this fact table reports sales by product name, sale month, and sale year. No other reports will be created against this table. You need to reduce the report processing time and minimize the growth

of the database. What should you do?

 

A. Partition the table by product type.

B. Create a view over the fact table to aggregate sales by month.
C. Change the granularity of the fact table to month.

D. Create an indexed view over the fact table to aggregate sales by month.

 

Correct Answer: C

 

QUESTION 52

You are designing a data warehouse for a software distribution business that stores sales by software title. It stores sales targets by software category. Software titles are classified into subcategories and categories. Each software title is included in only a single software subcategory, and each subcategory is included in only a single category. The data warehouse will be a data source for an Analysis Services cube. The data warehouse contains two fact tables:


• factSales, used to record daily sales by software title

• factTarget, used to record the monthly sales targets by software category

Reports must be developed against the warehouse that reports sales by software title, category and subcategory, and sales targets. You need to design the software title dimension. The solution should use as few tables as possible while supporting all the requirements. What should you do?

 

A. Create three software tables, dimSoftware, dimSoftwareCategory. and dimSoftwareSubcategory and a fourth bridge table that joins software titles to their appropriate category and subcategory table records with foreign key constraints. Direct the cube developer to use key granularity attributes.

B. Create three software tables, dimSoftware, dimSoftwareCategory, and dimSoftwareSubcategory.

Connect factSales to all three tables and connect factTarget to dimSoftwareCategory with foreign key constraints. Direct the cube developer to use key granularity attributes.

C. Create one table, dimSoftware, which contains Software Detail, Category, and Subcategory columns. Connect factSales to dimSoftware with a foreign key constraint. Direct the cube developer to use a non-key granularity attribute for factTarget.

D. Create two tables, dimSoftware and dimSoftwareCategory. Connect factSales to dimSoftware and factTarget to dimSoftwareCategory with foreign key constraints. Direct the cube developer to use key granularity attributes.

 

Correct Answer: C

 

QUESTION 53

You are reviewing the design of a customer dimension table in an existing data warehouse hosted on SQL Azure. The current dimension design does not allow the retention of historical changes to customer attributes such as Postcode. You need to redesign the dimension to enable the full

historical reporting of changes to multiple customer attributes including Postcode. What should you do?

 

A. Add StartDate and EndDate columns to the customer dimension.
B. Add an IsCurrent column to the customer dimension.

C. Enable Snapshot Isolation on the data warehouse.

D. Add CurrentValue and PreviousValue columns to the customer dimension.

 

Correct Answer: A

 

QUESTION 54

You are designing an enterprise star schema that will consolidate data from three independent data marts. One of the data marts is hosted on SQL Azure. Most of the dimensions have the same structure and content. However, the geography dimension is slightly different in each data mart. You need to design a consolidated dimensional structure that will be easy to maintain while ensuring

that all dimensional data from the three original solutions is represented. What should you do?

 

A. Create a junk dimension for the geography dimension.
B. Implement change data capture.

C. Create a conformed dimension for the geography dimension.
D. Create three geography dimensions.

 

Correct Answer: C
