QUESTION 41
Your database contains tables named Products and ProductsPriceLog. The Products table contains columns named ProductCode and Price. The ProductsPriceLog table contains columns named ProductCode, OldPrice, and NewPrice. The ProductsPriceLog table stores the previous price in the OldPrice column and the new price in the NewPrice column. You need to increase the values in the Price column of all products in the Products table by 5 percent. You also need to log the changes to the ProductsPriceLog table. Which Transact-SQL query should you use?

OUTPUT inserted.ProductCode, deleted.Price, inserted.Price
INTO ProductsPriceLog(ProductCode, OldPrice, NewPrice)
B.    UPDATE Products SET Price = Price * 1.05
OUTPUT inserted.ProductCode, inserted.Price, deleted.Price
INTO ProductsPriceLog(ProductCode, OldPrice, NewPrice)
C.    UPDATE Products SET Price = Price * 1.05
OUTPUT inserted.ProductCode, deleted.Price, inserted.Price *
INTO ProductsPriceLog(ProductCode, OldPrice, NewPrice)

QUESTION 42
You are developing a database application by using Microsoft SQL Server 2012. An application that uses a database begins to run slowly. Your investigation shows the root cause is a query against a read-only table that has a clustered index. The query returns the following six columns:
One column in its WHERE clause contained in a non-clustered index
Four additional columns
One COUNT (*) column based on a grouping of the four additional columns
You need to optimize the statement. What should you do?

A.    Add a HASH hint to the query.
B.    Add a LOOP hint to the query.
C.    Add a FORCESEEK hint to the query.
D.    Add an INCLUDE clause to the index.
E.    Add a FORCESCAN hint to the Attach query.
F.    Add a columnstore index to cover the query.
G.    Enable the optimize for ad hoc workloads option.
H.    Cover the unique clustered index with a columnstore index.
I.    Include a SET FORCEPLAN ON statement before you run the query.
J.    Include a SET STATISTICS PROFILE ON statement before you run the query.
K.    Include a SET STATISTICS SHOWPLAN_XML ON statement before you run the query.
L.    Include a SET TRANSACTION ISOLATION LEVEL REPEATABLE READ statement before you run the query.
M.    Include a SET TRANSACTION ISOLATION LEVEL SNAPSHOT statement before you run the query.
N.    Include a SET TRANSACTION ISOLATION LEVEL SERIALIZABLE statement before you run the query.

Answer: F
