You are designing a data warehouse that uses SQL Server 2012.
The data warehouse contains a table named factSales that stores product sales. The table
has a clustered index on the primary key, four foreign keys to dimension tables, and an
aggregate column for sales totals. All key columns use the int data type and the aggregate
column uses the money data type.
You need to increase the speed of data retrieval from the factSales table.
Which index type should you add to the table?
A.
Clustered
B.
Semantic search
