1.You need to create a column that allows you to create a unique constraint.
Which two column definitions should you choose? (Each correct answer presents a complete solution. Choose two.)
A. nvarchar(100) NULL
B. nvarchar(max) NOT NULL
C. nvarchar(100) NOT NULL
D. nvarchar(100) SPARSE NULL
Answer: AC

3. Your database is 5GB and contains a table named SalesHistory. Sales information is frequently inserted and updated.
You discover that excessive page splitting is occurring.
You need to reduce the occurrence of page splitting in the SalesHistory table.
Which code segment should you use?.
A. ALTER DATABASE Sales
MODIFY FILE
(NAME = Salesdat3,
SIZE = 10GB);
B. ALTER INDEX ALL ON Sales.SalesHistory
REBUILD WITH (FILLFACTOR = 60);
C. EXEC sys.sp_configure 'fill factor (%)', '60';
D. UPDATE STATISTICS Sales.SalesHistory(Products)
WITH FULLSCAN, NORECOMPUTE;
Answer: B

4. You administer a SQL Server 2008 database that contains a table name dbo.Sales, which contains the following table definition:
CREATE TABLE [dbo].[Sales](
[SalesID] [int] IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
[OrderDate] [datetime] NOT NULL,
[CustomerID] [int] NOT NULL,
[SalesPersonID] [int] NULL,
[CommentDate] [date] NULL);
This table contains millions of orders. You run the following query to determine when sales persons comment in the dbo.Sales table:
SELECT SalesID,CustomerID,SalesPersonID,CommentDate
FROM dbo.Sales
WHERE CommentDate IS NOT NULL
AND SalesPersonID IS NOT NULL;
You discover that this query runs slow. After examining the data, you find only 1% of rows have comment dates and the SalesPersonID is null on 10% of the rows. You need to create an index to optimize the query. The index must conserve disk space while optimizing your query.
Which index should you create?
A. CREATE NONCLUSTERED INDEX idx1
ON dbo.Sales (CustomerID)
INCLUDE (CommentDate,SalesPersonID);
B. CREATE NONCLUSTERED INDEX idx1
ON dbo.Sales (SalesPersonID)
INCLUDE (CommentDate,CustomerID);
C. CREATE NONCLUSTERED INDEX idx1
ON dbo.Sales (CustomerID)
INCLUDE(CommentDate)
WHERE SalesPersonID IS NOT NULL;
D. CREATE NONCLUSTERED INDEX idx1
ON dbo.Sales (CommentDate, SalesPersonID)
INCLUDE(CustomerID)
WHERE CommentDate IS NOT NULL;
Answer: D

5. You have a table named AccountsReceivable. The table has no indexes. There are 75,000 rows in the table. You have a partition function named FG_AccountData. The AccountsReceivable table is defined in the following Transact-SQL statement:
CREATE TABLE AccountsReceivable (
column_a INT NOT NULL,
column_b VARCHAR(20) NULL)
ON [PRIMARY];
You need to move the AccountsReceivable table from the PRIMARY file group to FG_AccountData.
Which Transact-SQL statement should you use?
A. CREATE CLUSTERED INDEX idx_AccountsReceivable
ON AccountsReceivable(column_a)
ON [FG_AccountData];
B. CREATE NONCLUSTERED INDEX idx_AccountsReceivable
ON AccountsReceivable(column_a)
ON [FG_AccountData];
C. CREATE CLUSTERED INDEX idx_AccountsReceivable
ON AccountsReceivable(column_a)
ON FG_AccountData(column_a);
D. CREATE NONCLUSTERED INDEX idx_AccountsReceivable
ON AccountsReceivable(column_a)
ON FG_AccountData(column_a);
Answer: C

6. You have a table named dbo.Customers. The table was created by using the following Transact-SQL statement:
CREATE TABLE dbo.Customers
(
CustomerID int IDENTITY(1,1) PRIMARY KEY CLUSTERED,
AccountNumber nvarchar(25) NOT NULL,
FirstName nvarchar(50) NOT NULL,
LastName nvarchar(50) NOT NULL,
AddressLine1 nvarchar(255) NOT NULL,
AddressLine2 nvarchar(255) NOT NULL,
City nvarchar(50) NOT NULL,
StateProvince nvarchar(50) NOT NULL,
Country nvarchar(50) NOT NULL,
PostalCode nvarchar(50) NOT NULL,
CreateDate datetime NOT NULL DEFAULT(GETDATE()),
ModifiedDate datetime NOT NULL DEFAULT(GETDATE())
)
You create a stored procedure that includes the AccountNumber, Country, and StateProvince columns from the dbo.Customers table. The stored procedure accepts a parameter to filter the output on the AccountNumber column.
You need to optimize the performance of the stored procedure. You must not change the existing structure of the table.
Which Transact-SQL statement should you use?
A. CREATE STATISTICS ST_Customer_AccountNumber
ON dbo.Customer (AccountNumber)
WITH FULLSCAN;
B. CREATE CLUSTERED INDEX IX_Customer_AccountNumber
ON dbo.Customer (AccountNumber);
C. CREATE NONCLUSTERED INDEX IX_Customer_AccountNumber
ON dbo.Customer (AccountNumber)
WHERE AccountNumber = '';
D. CREATE NONCLUSTERED INDEX IX_Customer_AccountNumber
ON dbo.Customer (AccountNumber)
INCLUDE (Country, StateProvince);
Answer: D

7. You manage a SQL Server 2008 database that is located at your company's corporate headquarters. The database contains a table named dbo.Sales. You need to create different views of the dbo.Sales table that will be used by each region to insert, update, and delete rows. Each regional office must only be able to insert, update, and delete rows for their respective region.
Which view should you create for Region1?
A. CREATE VIEW dbo.Region1Sales
AS
SELECT SalesID,OrderQty,SalespersonID,RegionID
FROM dbo.Sales
WHERE RegionID = 1;
B. CREATE VIEW dbo.Region1Sales
AS
SELECT SalesID,OrderQty,SalespersonID,RegionID
FROM dbo.Sales
WHERE RegionID = 1
WITH CHECK OPTION;
C. CREATE VIEW dbo.Region1Sales
WITH SCHEMABINDING
AS
SELECT SalesID,OrderQty,SalespersonID,RegionID
FROM dbo.Sales
WHERE RegionID = 1;
D. CREATE VIEW dbo.Region1Sales
WITH VIEW_METADATA
AS
SELECT SalesID,OrderQty,SalespersonID,RegionID
FROM dbo.Sales
WHERE RegionID = 1;
Answer: B

8. You have a user named John. He has SELECT access to the Sales schema. You need to eliminate John's SELECT access rights from the Sales.SalesOrder table without affecting his other permissions.
Which Transact-SQL statement should you use?
A. DROP USER John;
B. DENY SELECT ON Sales.SalesOrder TO John;
C. GRANT DELETE ON Sales.SalesOrder TO John;
D. REVOKE SELECT ON Sales.SalesOrder FROM John;
Answer: B

2. You have a table named Customer.
You need to ensure that customer data in the table meets the following requirements:
credit limit must be zero unless customer identification has been verified.
credit limit must be less than 10,000.
Which constraint should you use?
A. CHECK (CreditLimt BETWEEN 1 AND 10000)
B. CHECK (Verified = 1 AND CreditLimt BETWEEN 1 AND 10000)
C. CHECK ((CreditLimt = 0 AND Verified = 0) OR (CreditLimt BETWEEN 1 AND 10000 AND Verified = 1))
D. CHECK ((CreditLimt = 0 AND Verified = 0) AND (CreditLimt BETWEEN 1 AND 10000 AND Verified = 1))
Answer: C
