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).

2. HOTSPOT
You are developing a SQL Server Integration Services (SSIS) package. An Execute SQL task in the package checks product stock levels and sets a package variable named InStock to TRUE or FALSE depending on the stock level found.
After the successful execution of the Execute SQL task, one of two data flow tasks must run, depending on the value of the InStock variable.
You need to set the precedence constraints.
Which value for the evaluation operation should you use? (To answer, select the appropriate option for the evaluation operation in the answer area.)

3. Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You are writing a SQL Server Integration Services (SSIS) package that transfers data from a legacy system.
Data integrity in the legacy system is very poor. Invalid rows are discarded by the package but must be logged to a CSV file for auditing purposes.
You need to establish the best technique to log these invalid rows while minimizing the amount of development effort.
What should you do?

A) Add a data tap on the output of a component in the package data flow.
B) Use the Project Deployment Wizard.
C) Create an OnError event handler.
D) Deploy the package to the Integration Services catalog by using dtutfl and use SQL Server to store the configuration.
E) Run the package by using the dtexecui.exe utility and the SQL Log provider.
F) Use the gacutil command.
G) Use the dtutil /copy command.
H) Deploy the package by using an msi file.
I) Run the package by using the dtexec /dumperror /conn command.
J) Run the package by using the dtexec /rep /conn command.
K) Create a reusable custom logging component.

4. You develop a SQL Server Integration Services (SSIS) package that imports Windows Azure SQL Database data into a data warehouse every night.
The Windows Azure SQL Database data contains many misspellings and variations of abbreviations. To import the data, a developer used the Fuzzy Lookup transformation to choose the closest-matching string from a reference table of allowed values. The number of rows in the reference table is very large.
If no acceptable match is found, the Fuzzy Lookup transformation passes a null value. The current setting for the Fuzzy Lookup similarity threshold is 0.50.
Many values are incorrectly matched.
You need to ensure that more accurate matches are made by the Fuzzy Lookup transformation without degrading performance.
What should you do?

A) Decrease the maximum number of matches per lookup.
B) Change the similarity threshold to 0.40.
C) Change the Exhaustive property to True.
D) Change the similarity threshold to 0.55.

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.
