QUESTION 121
You create a stored procedure that retrieves all of the rows from a table named Table1.
You need to recommend a solution to ensure that all of the statements in the stored procedure can be executed if another transaction is modifying rows in Table1 simultaneously.
What should you recommend?

A.    Snapshot isolation
B.    A database snapshot
C.    Filegroups
D.    Indexes

Answer: A
Explanation:
Once snapshot isolation is enabled, updated row versions for each transaction are maintained in tempdb. A unique transaction sequence number identifies each transaction, and these unique numbers are recorded for each row version. The transaction works with the most recent row versions having a sequence number before the sequence number of the transaction. Newer row versions created after the transaction has begun are ignored by the transaction.
Transaction Isolation Levels

QUESTION 122
You have a SQL Server instance on a server named Server1.
You need to recommend a solution to perform the following tasks every week:
– Rebuild the indexes by using a new fill factor.

What should you recommend?
More than one answer choice may achieve the goal. Select the BEST answer.

A.    A trigger
B.    An alert
C.    A maintenance plan
D.    Windows PowerShell
E.    A system policy

Answer: C
Explanation:
Maintenance plans create a workflow of the tasks required to make sure that your database is optimized, regularly backed up, and free of inconsistencies.

QUESTION 123
Hotspot Question
You use SQL Server 2014. You create a table within a database by using the following DDL:
 
The following table illustrates a representative sample of data:
 
The system is expected to handle 50 million orders a month over the next five years.
You have been instructed by your Team Lead to follow best practices for storage and performance in the utilization of SPARSE columns.

QUESTION 124
Drag and Drop Questions
You plan to deploy a database to SQL Azure.
You are designing two stored procedures named USP_1 and USP_2 that have the following requirements:
– Prevent data read by USP_1 from being modified by other active processes.
– Allow USP_2 to perform dirty reads.
You need to recommend the isolation level for the stored procedures.
The solution must maximize concurrency.
Which isolation levels should you recommend? To answer, drag the appropriate isolation level to the correct stored procedure in the answer area.
 
Answer:
 

QUESTION 125
You use SQL Server 2014 to maintain the data used by applications at your company.
You want to execute two statements.
You need to guarantee that either both statements succeed, or both statements fail together as a batch.
Which code should you use?
 

A.    Option A
B.    Option B
C.    Option C
D.    Option D
E.    Option E

Answer: D
Explanation:
Structure should be:
BEGIN TRY

END CATCH.
TRY…CATCH (Transact-SQL)

QUESTION 126
You deploy a SQL Server instance named SQLProd that uses SQL Server 2014.
You need to recommend a solution to monitor the transactions that are running currently against SQLProd. The solution must minimize the amount of custom code required.
What should you recommend?

A.    Statistics
B.    A dynamic management view
C.    A trigger
D.    User-defined views

Answer: B
Explanation:
Dynamic management views and functions return server state information that can be used to monitor the health of a server instance, diagnose problems, and tune performance.
Transactions can be monitored.
Dynamic Management Views and Functions (Transact-SQL)

QUESTION 127
Drag and Drop Questions
You have a SQL Azure database named Database1.
You need to design the schema for a table named table1. Table1 will have less than one million rows. Table1 will contain the following information for each row:
 
The solution must minimize the amount of space used to store each row.
Which data types should you recommend for each column? To answer, drag the appropriate data type to the correct column in the answer area.
 
Answer:
 

QUESTION 128
You have a SQL Server 2014 instance named SQL1.
SQL1 creates error events in the Windows Application event log.
You need to recommend a solution that will run an application when SQL1 logs a specific error in the Application log.

A.    A policy
B.    A maintenance plan
C.    An alert
D.    A job
E.    A trigger

QUESTION 129
You have a database named DB1.
You plan to create a stored procedure that will insert rows into three different tables. Each insert must use the same identifying value for each table, but the value must increase from one invocation of the stored procedure to the next.
Occasionally, the identifying value must be reset to its initial value.
You need to design a mechanism to hold the identifying values for the stored procedure to use.
What should you do? More than one answer choice may achieve the goal. Select the BEST answer.

A.    Create a sequence object that holds the next value in the sequence.
Retrieve the next value by using the stored procedure.
Reset the value by using an ALTER SEQUENCE statement as needed.
B.    Create a sequence object that holds the next value in the sequence.
Retrieve the next value by using the stored procedure.
Increment the sequence object to the next value by using an ALTER SEQUENCE statement.
Reset the value as needed by using a different ALTER SEQUENCE statement.
C.    Create a fourth table that holds the next value in the sequence.
At the end each transaction, update the value by using the stored procedure.
Reset the value as needed by using an UPDATE statement.
D.    Create an identity column in each of the three tables.
Use the same seed and the same increment for each table.
Insert new rows into the tables by using the stored procedure.
Use the DBCC CHECKIDENT command to reset the columns as needed.

Answer: A
Explanation:
* an application can obtain the next sequence number without inserting the row by calling the NEXT VALUE FOR function.
* ALTER SEQUENCE
Includes argument:
RESTART [ WITH <constant> ]
The next value that will be returned by the sequence object. If provided, the RESTART WITH value must be an integer that is less than or equal to the maximum and greater than or equal to the minimum value of the sequence object. If the WITH value is omitted, the sequence numbering restarts based on the original CREATE SEQUENCE options.
* CREATE SEQUENCE
Creates a sequence object and specifies its properties. A sequence is a user-defined schema bound object that generates a sequence of numeric values according to the specification with which the sequence was created. The sequence of numeric values is generated in an ascending or descending order at a defined interval and can be configured to restart (cycle) when exhausted.
Sequence Numbers

QUESTION 130
Your network contains an Active Directory domain that has two groups named Group1 and Group2.
The domain contains two SQL Server instances named SQLDev and SQLProd.
Each SQL Server instance has access to various storage media.
The SQL Server instances have a database that contains a table named Table1.
Table1 contains a column named Column1.
The value for Column1 can be either Value1 or Value2.
You need to recommend a solution to ensure that users in Group1 can retrieve only rows from Column1 that contain the value of Value1.
What should you recommend?

A.    A dynamic management view
B.    Filegroups
C.    Snapshot isolation
D.    User-defined views

Answer: D
Explanation:
A view is a virtual table whose contents are defined by a query. Like a table, a view consists of a set of named columns and rows of data. Unless indexed, a view does not exist as a stored set of data values in a database. The rows and columns of data come from tables referenced in the query defining the view and are produced dynamically when the view is referenced.
A view acts as a filter on the underlying tables referenced in the view. http://msdn.microsoft.com/en-us/library/ms190174.aspx
Incorrect:
Not A: Dynamic management views and functions return server state information that can be used to monitor the health of a server instance, diagnose problems, and tune performance.
