Microsoft 070-457 Exam Syllabus Topics:

Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 1 Sample Questions:

1. You administer a Microsoft SQL Server 2012 Enterprise Edition server that uses 64 cores. You discover performance issues when large amounts of data are written to tables under heavy system load. You need to limit the number of cores that handle I/O. What should you configure?

A) Processor affinity
B) Max worker threads
C) Lightweight pooling
D) I/O affinity

2. DRAG AND DROP You administer several Microsoft SQL Server 2012 servers. Your company has a number of offices across the world connected by using a wide area network (WAN). Connections between offices vary significantly in both bandwidth and reliability. You need to identify the correct replication method for each scenario. What should you do? (To answer, drag the appropriate replication method or methods to the correct location or locations in the answer area. Each replication method may be used once, more than once, or not at all.)
Select and Place:

3. 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] hierarchyid,
[Document] NVARCHAR NOT NULL
)
GO
B) CREATE TABLE DocumentStore AS FileTable
C) CREATE TABLE DocumentStore
(
[Id] INT NOT NULL PRIMARY KEY,
[Document] VARBINARY(MAX) NULL
)
GO
D) CREATE TABLE DocumentStore
(
[Id] [uniqueidentifier] ROWGUIDCOL NOT NULL UNIQUE,
[Document] VARBINARY(MAX) FILESTREAM NULL
)
GO

4. You develop a Microsoft SQL Server 2012 server database that supports an application. The application contains a table that has the following definition:
CREATE TABLE Inventory (
ItemID int NOT NULL PRIMARY KEY,
ItemsInStore int NOT NULL,
ItemsInWarehouse int NOT NULL)
You need to create a computed column that returns the sum total of the ItemsInStore and ItemsInWarehouse values for each row. The new column is expected to be queried heavily, and you need to be able to index the column. Which Transact-SQL statement should you use?

A) ALTER TABLE Inventory ADD TotalItems AS ItemslnStore + ItemsInWarehouse
B) ALTER TABLE Inventory ADD TotalItems AS ItemsInStore + ItemsInWarehouse PERSISTED
C) ALTER TABLE Inventory ADD TotalItems AS SUM(ItemsInStore, ItemsInWarehouse)
D) ALTER TABLE Inventory ADD TotalItems AS SUM(ItemsInStore, ItemsInWarehouse) PERSISTED

5. You administer a Microsoft SQL Server 2012 database. You configure Transparent Data Encryption (TDE) on the Orders database by using the following statements:
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'MyPassword1!'
CREATE CERTIFICATE TDE_Certificate WITH SUBJECT = 'TDE Certificate';
BACKUP CERTIFICATE TDE_Certificate TO FILE = ''d:\TDE_Certificate.cer'
WITH PRIVATE KEY (FILE = 'D:\TDE_Certificate.key', ENCRYPTION BY PASSWORD =
'MyPassword1!');
CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
ALTER DATABASE Orders SET ENCRYPTION ON;
You attempt to restore the Orders database and the restore fails. You copy the encryption file to the original location. A hardware failure occurs and so a new server must be installed and configured. After installing SQL Server to the new server, you restore the Orders database and copy the encryption files to their original location. However, you are unable to access the database. You need to be able to restore the database. Which Transact-SQL statement should you use before attempting the restore?

A) CREATE CERTIFICATE TDE_Certificate FROM FILE = 'd:\TDE_Certificate.cer' WITH PRIVATE KEY (FILE = 'D:\TDE_Certificate.key', DECRYPTION BY PASSWORD = 'MyPassword1!');
B) ALTER DATABASE Master SET ENCRYPTION OFF;
C) CREATE CERTIFICATE TDE_Certificate FROM FILE = 'd:\TDE_Certificate.cer';
D) CREATE CERTIFICATE TDE_Certificate WITH SUBJECT = 'TDE Certificate'; USE Orders; CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
