Q1. You develop a Microsoft SQL Server 2012 database that contains a table named Customers. The Customers table has the following definition:
You need to create an audit record only when either the MobileNumber or HomeNumber column is updated.
Which Transact-SQL query should you use?
A. CREATE TRIGGER TrgPhoneNumberChange ON Customers FOR UPDATE AS IF COLUMNS_UPDATED (HomeNumber, MobileNumber) - - Create Audit Records
B. CREATE TRIGGER TrgPhoneNumberChange ON Customers FOR UPDATE AS IF EXISTS( SELECT HomeNumber FROM inserted) OR EXISTS (SELECT MobileNumber FROM inserted) - - Create Audit Records
C. CREATE TRIGGER TrgPhoneNumberChange ON Customers FOR UPDATE AS IF COLUMNS_CHANGED (HomeNumber, MobileNumber) - - Create Audit Records
D. CREATE TRIGGER TrgPhoneNumberChange ON Customers FOR UPDATE AS IF UPDATE (HomeNumber) OR UPDATE (MobileNumber) - - Create Audit Records
Answer: D
Q2. You develop a Microsoft SQL Server 2012 database that contains tables named Customers and Orders. The tables are related by a column named CustomerId.
You need to create a query that meets the following requirements:
. Returns the CustomerName for all customers and the OrderDate for any orders that they have placed. . Results must not include customers who have not placed any orders.
Which Transact-SQL query should you use?
A. SELECT CustomerName, OrderDate FROM Customers LEFT OUTER JOIN Orders ON Customers.CuscomerlD = Orders.CustomerId
B. SELECT CustomerName, OrderDate FROM Customers RIGHT OUTER JOIN Orders ON Customers.CustomerID = Orders.CustomerId
C. SELECT CustomerName, OrderDate FROM Customers CROSS JOIN Orders ON Customers.CustomerId = Orders.CustomerId
D. SELECT CustomerName, OrderDate FROM Customers JOIN Orders ON Customers.CustomerId = Orders.CustomerId
Answer: D
Q3. You create a table that has the StudentCode, SubjectCode, and Marks columns to record mid-year marks for students. The table has marks obtained by 50 students for various subjects.
You need to ensure that the top half of the students arranged by their average marks must be given a rank of 1 and the remaining students must be given a rank of 2. Which Transact-SQL query should you use?
A. SELECT StudentCode as Code, RANK() OVER (ORDER BY AVG (Marks) DESC) AS Value FROM StudentMarks GROUP BY StudentCode
B. SELECT Id, Name, Marks, DENSE_RANK() OVER (ORDER BY Marks DESC) AS Rank FROM StudentMarks
C. SELECT StudentCode as Code, DENSE_RANK() OVER (ORDER BY AVG (Marks) DESC) AS Value FROM StudentMarks GROUP BY StudentCode
D. SELECT StudentCode as Code, NTILE (2) OVER (ORDER BY AVG (Marks) DESC) AS Value FROM StudentMarks GROUP BY StudentCode
E. SELECT StudentCode AS Code,Marks AS Value FROM ( SELECT StudentCode, Marks AS Marks, RANK() OVER (PARTITION BY SubjectCode ORDER BY Marks ASC) AS Rank FROM StudentMarks) tmp WHERE Rank = 1
F. SELECT StudentCode AS Code,Marks AS Value FROM ( SELECT StudentCode, Marks AS Marks, RANK() OVER (PARTITION BY SubjectCode ORDER BY Marks DESC) AS Rank FROM StudentMarks) tmp WHERE Rank = 1
G. SELECT StudentCode AS Code,Marks AS Value FROM ( SELECT StudentCode, Marks AS Marks, RANK () OVER (PARTITION BY StudentCode ORDER BY Marks ASC) AS Rank FROM StudentMarks) tmp WHERE Rank = 1
H. SELECT StudentCode AS Code,Marks AS Value FROM ( SELECT StudentCode, Marks AS Marks, RANXO OVER (PARTITION BY StudentCode ORDER BY Marks DESC) AS Rank FROM StudentMarks) tmp WHERE Rank = 1
Answer: D
Q4. CORRECT TEXT
You have a database named Sales that contains the tables shown in the exhibit. (Click the Exhibit button.)
You have an application named Appl. You have a parameter named @Count that uses the
int data type. App1 is configured to pass @Count to a stored procedure.
You need to create a stored procedure named usp_Customers for App1 that returns only
the number of rows specified by the @Count parameter.
The solution must NOT use BEGIN and END statements.
Part of the correct T-SQL statement has been provided in the answer area. Provide the
complete code.
Answer:
Q5. You create a view based on the following statement:

Which Transact-SQL statement should you use?
A. Option A
B. Option B
C. Option C

Q6. You use a Microsoft SQL Server 2012 database.
You want to create a table to store Microsoft Word documents.
You need to ensure that the documents must only be accessible via Transact-SQL queries.
Which Transact-SQL statement should you use?
A. CREATE TABLE DocumentStore ( [Id] INT NOT NULL PRIMARY KEY, [Document] VARBINARY(MAX) NULL ) GO
B. CREATE TABLE DocumentStore ( [Id] hierarchyid, [Document] NVARCHAR NOT NULL ) GO
C. CREATE TABLE DocumentStore AS FileTable
D. CREATE TABLE DocumentStore ( [Id] [uniqueidentifier] ROWGUIDCOL NOT NULL UNIQUE, [Document] VARBINARY(MAX) FILESTREAM NULL ) GO
Answer: A
Q7. DRAG DROP
You administer a Microsoft SQL Server 2012 database. You use an OrderDetail table that has the following definition:
You need to create a non-clustered index on the SalesOrderID column in the OrderDetail table to include only rows that contain a value in the SpecialOfferID column. Which four Transact-SQL statements should you use?
(To answer, move the appropriate statements from the list of statements to the answer area and arrange them in the correct order.)
Answer:
Q8. You are developing a database application by using Microsoft SQL Server 2012. You have a query that runs slower than expected.
You need to capture execution plans that will include detailed information on missing indexes recommended by the query optimizer.
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.

Answer: K
Q9. You use a Microsoft SQL Server 2012 database that contains two tables named SalesOrderHeader and SalesOrderDetail. The indexes on the tables are as shown in the exhibit. (Click the Exhibit button.)
You write the following Transact-SQL query:
You discover that the performance of the query is slow. Analysis of the query plan shows table scans where the estimated rows do not match the actual rows for SalesOrderHeader by using an unexpected index on SalesOrderDetail.
You need to improve the performance of the query.
What should you do?
