Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 2 Sample Questions:

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 implement log shipping of the financial database to another SQL Server 2012 instance. You decide to failoverto this secondary database.
You need to ensure that all transactions will be replicated to the secondary database.
Which backup option should you use?

A) FULL
B) NORECOVERY
C) SKIP
D) SIMPLE
E) STANDBY
F) BULK_LOGGED
G) Differential
H) Transaction log
I) RESTART
J) COPY_ONLY
K) DBO_ONLY
L) CHECKSUM
M) CONTINUE_AFTER_ERROR
N) NO_CHECKSUM

2. DRAG DROP
You administer three Microsoft SQL Server 2012 servers named ServerA, Servers, and ServerC.
ServerA is the acting principal and ServerB is the mirror.
You need to add ServerC as a witness to the existing mirroring session between ServerA and ServerB. You need to achieve this goal without delaying synchronization.
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.)

3. You are developing a SQL Server Integration Services (SSIS) package to implement an incremental data load strategy.
The package reads data from a source system. Depending on the value in a source column, the package redirects rows to one of five different data flow paths.
You need to add a data flow transformation to support the package redirection.
Which data flow transformation should you use?

A) Conditional Split
B) Pivot
C) Lookup
D) Multicast

4. You are developing a SQL Server Integration Services (SSIS) package.
The package uses a data flow task to source data from a SQL Server database for loading into a dimension table in a data warehouse.
You need to create a separate data flow path for data that has been modified since it was last processed.
Which data flow components should you use to identify modified data? (Each correct answer presents a complete solution. Choose all that apply.)

A) Slowly Changing Dimension
B) Lookup
C) Aggregate
D) Multicast
E) Data Conversion

5. You are developing a SQL Server Integration Services (SSIS) package to implement an incremental data load strategy. The package reads data from a source system that uses the SQL Server change data capture (CDC) feature.
You have added a CDC Source component to the data flow to read changed data from the source system.
You need to add a data flow transformation to redirect rows for separate processing of insert, update, and delete operations.
Which data flow transformation should you use?

A) CDC Splitter
B) DQS Cleansing
C) Merge Join
D) Pivot
