Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 2 (070-458) Free Practice Test
Question 1
----
You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area network (SAN).
The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D).
A transaction log of 10 GB is located on a dedicated LUN (drive E).
Drive D has 1 terabyte of free disk space.
Drive E has S GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database.
These data load operations must occur in the minimum amount of time.
A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
You need to ensure that the backup size is as small as possible.
Which backup should you perform every two hours?

Correct Answer: H
Question 2
DRAG DROP
You are developing a SQL Server Integration Services (SSIS) package that downloads data from a Windows Azure SQL Database database.
A stored procedure will be called in an Execute SQL task by using an ODBC connection. This stored procedure has only the rustomerlD parameter of type INT.
A project parameter named CustID will be mapped to the stored procedure parameter @CustomerID.
You need to ensure that the value of the CustID parameter is passed to the @CustomerID stored procedure parameter.
In the Parameter Mapping tab of the Execute SQL task editor, how should you configure the parameter? (To answer, drag the appropriate option or options to the correct location or locations in the answer area.)

Question 3
You administer a Microsoft SQL Server 2012 database that contains a table named AccountTransaction.
You discover that query performance on the table is poor due to fragmentation on the IDX_AccountTransaction_AccountCode non-clustered index.
You need to defragment the index. You also need to ensure that user queries are able to use the index during the defragmenting process,
Which Transact-SQL batch should you use?

Correct Answer: A
Question 4
You administer a Microsoft SQL Server 2012 database that has Trustworthy set to on. You create a stored procedure that returns database-level information from Dynamic Management Views.
You grant User1 access to execute the stored procedure.
You need to ensure that the stored procedure returns the required information when User1 executes the stored procedure. You need to achieve this goal by granting the minimum permissions required.
What should you do? Choose all that apply.

Correct Answer: D,E
Question 5
Note: This question is part of a series of questions that use the same set of answer choices. An answer choice may be correct for more than one question in the series.
You administer a Microsoft SQL Server 2012 server that hosts a transactional database and a reporting database. The transactional database is updated through a web application and is operational throughout the day. The reporting database is only updated from the transactional database.
The recovery model and backup schedule are configured as shown in the following table:
The differential backup of the reporting database fails. Then, the reporting database fails at
14:00 hours.
You need to ensure that the reporting database is restored. You also need to ensure that
data loss is minimal.

Question 6
You administer a Microsoft SQL Server database named Sales. The database is 3 terabytes in size. The Sales database is configured as shown in the following table.
You discover that all files except Sales_2.ndf are corrupt.
You need to recover the corrupted data in the minimum amount of time.

Correct Answer: B
Question 7
HOTSPOT
You are developing a SQL Server Integration Service (SSIS) package. The package loads a customer dimension table by using a data flow task.
Changes to the customer attributes must be tracked over time.
You need to produce a checksum value to identify the rows that have changed since the last Extract, Transform and Load (ETL) process execution. You need to use the least amount of development effort to achieve this goal.
Which transformation should you use? (To answer, select the appropriate transformation in the answer area.)

Question 8
DRAG DROP
All database traffic to the SQL Server must be encrypted by using secure socket layer (SSL) certificates or the connection must be refused.
Network administrators have deployed server certificates to the Windows store of all Windows servers on the network from a trusted Certificate Authority. This is the only Certificate Authority allowed to distribute certificates on the network.
You enable the Force Encryption flag for the MSSQLServer protocols, but client computers are unable to connect. They receive the following error message:
"A connection was successfully established with the server, but then an error occurred during the pre-login handshake, (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (Microsoft SQL Server)"
You notice the following entry in the SQL Server log:
"A self-generated certificate was successfully loaded for encryption."
You need to configure SQL Server to encrypt all client traffic across the network. You also need to ensure that client computers are able to connect to the server by using a trusted certificate.
Which three actions should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order,)
