Users frequently run the following query. The users report that the query takes a long time to return results.
You need to minimize the amount of time required for the query to return data.
A . Create clustered indexes on TBL1 and TBL2.
B . Create a clustered index on TBL1.Create a nonclustered index on TBL2 and add the most frequently queried column as included columns.
C . Create a nonclustered index on TBL2 only.
D . Create UNIQUEconstraints on both TBL1 and TBL2. Create a partitioned view that combines columns from TBL1 and TBL2.
E . Drop existing indexes on TBL1 and then create a clustered columnstore index. Create a nonclustered columnstore index on TBL1.Create a nonclustered index on TBL2.
F . Drop existing indexes on TBL1 and then create a clustered columnstore index. Create a nonclustered columnstore index on TBL1.Make no changes to TBL2.
G . Create CHECK constraints on both TBL1 and TBL2. Create a partitioned view that combines columns from TBL1 and TBL2.
H . Create an indexed view that combines columns from TBL1 and TBL2.
Answer: D
Explanation:
A partitioned view is a view defined by a UNION ALL of member tables structured in the same way, but stored separately as multiple tables in either the same instance of SQL Server or in a group of autonomous instances of SQL Server servers, called federated database servers.
