Q16. You administer several Microsoft SQL Server 2012 database servers. Merge replication has been configured for an application that is distributed across offices throughout a wide area network (WAN). Many of the tables involved in replication use the XML and varchar (max) data types. Occasionally, merge replication fails due to timeout errors. You need to reduce the occurrence of these timeout errors. What should you do? 

A. Set the Merge agent on the problem subscribers to use the slow link agent profile. 

B. Create a snapshot publication, and reconfigure the problem subscribers to use the snapshot publication. 

C. Change the Merge agent on the problem subscribers to run continuously. 

D. Set the Remote Connection Timeout on the Publisher to 0.

Q17. 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? 

A. UPDATE Products SET Price = Price * 1.05 

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) 

D. UPDATE Products SET Price = Price * 1.05 

INSERT INTO ProductsPriceLog (ProductCode, CldPnce, NewPrice; 

SELECT ProductCode, Price, Price * 1.05 FROM Products

You have a view that was created by using the following code: 

You need to create an inline table-valued function named Sales.fn_OrdersByTerritory, which must meet the following requirements:

...

Q19. Your database contains a table named Purchases. The table includes a DATETIME column named PurchaseTime that stores the date and time each purchase is made. There is a non-clustered index on the PurchaseTime column. 

The business team wants a report that displays the total number of purchases made on the current day. 

You need to write a query that will return the correct results in the most efficient manner. 

Which Transact-SQL query should you use? 

A. SELECT COUNT(*) 

FROM Purchases 

WHERE PurchaseTime = CONVERT(DATE, GETDATE()) 

B. SELECT COUNT(*) 

FROM Purchases 

WHERE PurchaseTime = GETDATE() 

C. SELECT COUNT(*) 

FROM Purchases 

WHERE CONVERT(VARCHAR, PurchaseTime, 112) = CONVERT(VARCHAR, 

GETDATE(), 112) 

D. SELECT COUNT(*) 

FROM Purchases 

WHERE PurchaseTime >= CONVERT(DATE, GETDATE()) 

AND PurchaseTime < DATEADD(DAY, 1, CONVERT(DATE, GETDATE())) 

Answer:

Explanation: 

Two answers will return the correct results (the "WHERE CONVERT..." and "WHERE ... AND ... " answers). The correct answer for Microsoft would be the answer that is most "efficient". Anybody have a clue as to which is most efficient? In the execution plan, the one that I've selected as the correct answer is the query with the shortest duration. Also, the query answer with "WHERE CONVERT..." threw warnings in the execution plan...something about affecting CardinalityEstimate and SeekPlan. 

I also found this article, which leads me to believe that I have the correct Answer: http://technet.microsoft.com/en-us/library/ms181034.aspx
