Q1. 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
Q2. CORRECT TEXT
You need to create a query that calculates the total sales of each OrderlD from a table named Sales.Details. The table contains two columns named OrderlD and ExtendedAmount.
The solution must meet the following requirements:
Use one-part names to reference columns.
Start the order of the results from OrderlD.
NOT depend on the default schema of a user.
Use an alias of TotalSales for the calculated ExtendedAmount.
Display only the OrderlD column and the calculated TotalSales column.
Provide the correct code in the answer area.

A. Use the CAST function.
B. Use the DATE data type.
C. Use the FORMAT function.
D. Use an appropriate collation.
E. Use a user-defined table type.
F. Use the VARBINARY data type.
G. Use the DATETIME data type.
H. Use the DATETIME2 data type.
I. Use the DATETIMEOFFSET data type.
J. Use the TODATETIMEOFFSET function.
Answer: E
Q4. CORRECT TEXT
You have a database that contains the tables as shown below:
You have a stored procedure named Procedure1. Procedure1 retrieves all order ids after a specific date. The rows for Procedure1 are not sorted. Procedure1 has a single parameter named Parameter1. Parameter1 uses the varchar type and is configured to pass the specific date to Procedure1. A database administrator discovers that OrderDate is not being compared correctly to Parameter1 after the data type of the column is changed to datetime. You need to update the SELECT statement to meet the following requirements:
The code must NOT use aliases.
The code must NOT use object delimiters.
The objects called in Procedure1 must be able to be resolved by all users.
OrderDate must be compared to Parameter1 after the data type of Parameter1 is
changed to datetime.
Which SELECT statement should you use?
To answer, type the correct code in the answer area.

You need to achieve this goal without taking the index offline. Which Transact-SQL batch should you use?
A. CREATE INDEX NCI_OrderDetail_CustomerID ON OrderDetail.CustomerID WITH DROP EXISTING
B. ALTER INDEX NCI_OrderDetail_CustomerID ON OrderDetail.CustomerID REORGANIZE
C. ALTER INDEX ALL ON OrderDetail REBUILD
D. ALTER INDEX NCI_OrderDetail_CustomerID ON OrderDetail.CustomerID REBUILD
Answer: B
Q6. CORRECT TEXT

E. SELECT Name, Country, OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId= 1 FOR XML AUTO
F. SELECT Name, Country, Orderld, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId= 1 FOR XML AUTO, ELEMENTS G. SELECT Name AS '@Name', Country AS '@Country', OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId= 1 FOR XML PATH ('Customers')
H. SELECT Name AS 'Customers/Name', Country AS 'Customers/Country', OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId= 1 FOR XML PATH ('Customers')
Answer: C
