Microsoft 070-458 Exam Syllabus Topics:

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

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

2. 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 SQL 2012 server that contains a database named SalesDb. SalesDb contains a schema named Customers that has a table named Regions. A user named userA is a member of a role named Sales.
UserA is granted the Select permission on the Regions table. The Sales role is granted the Select permission on the Customers schema.
You need to remove the Select permission for userA on the Regions table. You also need to ensure that UserA can still access all the tables in the Customers schema, including the Regions table, through the Sales role permissions.
Which Transact-SQL statement should you use?

A) DENY SELECT ON Schema: Customers FROM UserA
B) DENY SELECT ON Schema:: Customers FROM Soles
C) REVOKE SELECT ON Object::Regions FROM Soles
D) DENY SELECT ON Object::Regions FROM UserA
E) DENY SELECT ON Object::Regions FROM Sales
F) EXEC sp_oddrolemember 'Sales', 'UserA'
G) REVOKE SELECT ON Object::Regions FROM UserA
H) REVOKE SELECT ON Schema: Customers FROM Soles
I) REVOKE SELECT ON Schema::Customers FROM UserA
J) EXEC 3p_droprolemember 'Sales', 'UserA'
