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 server. You plan to deploy new features to an application. You need to evaluate existing and potential clustered and non-clustered indexes that will improve performance. What should you do?

B) Query the sys.dm_db_missing_index_details DMV.
C) Query the sys.dm_db_index_usage_stats DMV.
D) Use the Database Engine Tuning Advisor.

2. You have a database that contains the tables shown in the exhibit. (Click the Exhibit button.)

You deploy a new server that has SQL Server 2012 installed. You need to create a table named Sales. OrderDetails on the new server. Sales.OrderDetails must meet the following requirements:
Write the results to a disk.

The solution must ensure that LineItemTotal is stored as the last column in the table. Which code segment
should you use?
To answer, type the correct code in the answer area.

A) CREATE TABLE Sales.OrderDetails ( ListPrice money not null, Quantity int not null, LineItemTotal as (ListPrice * Quantity))
B) CREATE TABLE Sales.OrderDetails ( ListPrice money not null, Quantity int not null, LineItemTotal as (ListPrice * Quantity) PERSISTED)

3. You develop a Microsoft SQL Server 2012 database. The database is used by two web applications that access a table named Products. You want to create an object that will prevent the applications from accessing the table directly while still providing access to the required data. You need to ensure that the following requirements are met:
Future modifications to the table definition will not affect the applications' ability to access data.
The new object can accommodate data retrieval and data modification.
You need to achieve this goal by using the minimum amount of changes to the existing applications.
What should you create for each application?

A) table partitions
B) stored procedures
C) views
D) table-valued functions

4. You support a database structure shown in the exhibit. (Click the Exhibit button.)

You need to write a query that displays the following details:
Total sales made by sales people, year, city, and country
Sub totals only at the city level and country level
A grand total of the sales amount
Which Transact-SQL query should you use?

A) SELECT SalesPerson.Name, Country, City, DatePart(yyyy, SaleDate) AS Year, Sum(Amount) AS Total FROM Sale INNER JOIN SalesPerson ON Sale.SalesPersonID = SalesPerson.SalesPersonID GROUP BY ROLLUP(SalesPerson.Name, DatePart(yyyy, SaleDate), City, Country)
B) SELECT SalesPerson.Name, Country, City, DatePart(yyyy, SaleDate) AS Year, Sum(Amount) AS Total FROM Sale INNER JOIN SalesPerson ON Sale.SalesPersonID = SalesPerson.SalesPersonID GROUP BY GROUPING SETS((SalesPerson.Name, Country, City, DatePart(yyyy, SaleDate)), (Country, City), (Country), ())
C) SELECT SalesPerson.Name, Country, City, DatePart(yyyy, SaleDate) AS Year, Sum(Amount) AS Total FROM Sale INNER JOIN SalesPerson ON Sale.SalesPersonID = SalesPerson.SalesPersonID GROUP BY CUBE(SalesPerson.Name, DatePart(yyyy, SaleDate), City, Country)
D) SELECT SalesPerson.Name, Country, City, DatePart(yyyy, SaleDate) AS Year, Sum(Amount) AS Total FROM Sale INNER JOIN SalesPerson ON Sale.SalesPersonID = SalesPerson.SalesPersonID GROUP BY CUBE(SalesPerson.Name, Country, City, DatePart(yyyy, SaleDate))

5. You administer a Microsoft SQL Server 2012 server. When transaction logs grow, SQL Server must send an email message to the database administrators. You need to configure SQL Server to send the email messages. What should you configure?
