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 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 5 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 need to ensure that your backup will continue if any invalid checksum is encountered. Which backup option should you use?

A) FULL

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

3. You administer all the deployments of Microsoft SQL Server 2012 in your company. A database contains a large product catalog that is updated periodically. You need to be able to send the entire product catalog to all branch offices on a monthly basis. Which configuration should you use?

B) SQL Server that includes an application database configured to perform transactional replication
C) Two servers configured in different data centers SQL Server Availability Group configured in Asynchronous-Commit Availability Mode
D) Two servers configured in different data centers SQL Server Availability Group configured in Synchronous-Commit Availability Mode
One server configured as an Active Secondary

4. Your database contains two tables named DomesticSalesOrders and InternationalSalesOrders. Both tables contain more than 100 million rows. Each table has a Primary Key column named SalesOrderId. The data in the two tables is distinct from one another. Business users want a report that includes aggregate information about the total number of global sales and total sales amounts. You need to ensure that your query executes in the minimum possible time. Which query should you use?

FROM (
SELECT SalesOrderId, SalesAmount
FROM DomesticSalesOrders
UNION
SELECT SalesOrderId, SalesAmount
FROM InternationalSalesOrders
) AS p
B) SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM DomesticSalesOrders UNION SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM InternationalSalesOrders
C) SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount
FROM (
SELECT SalesOrderId, SalesAmount
FROM DomesticSalesOrders
UNION ALL
SELECT SalesOrderId, SalesAmount
FROM InternationalSalesOrders
) AS p
D) SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM DomesticSalesOrders UNION ALL SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM InternationalSalesOrders

5. You are a database developer of a Microsoft SQL Server 2012 database. You are designing a table that will store Customer data from different sources.

A) CREATE TABLE Customer (SourceID int NOT NULL, CustomerID int NOT NULL PRIMARY KEY CLUSTERED, CustomerName varchar(255) NOT NULL);
B) CREATE TABLE Customer (SourceID int NOT NULL PRIMARY KEY CLUSTERED, CustomerID int NOT NULL UNIQUE, CustomerName varchar(255) NOT NULL);
C) CREATE TABLE Customer (SourceID int NOT NULL, CustomerID int NOT NULL, CustomerName varchar(255) NOT NULL, CONSTRAINT UQ_Customer UNIQUE CLUSTERED (SourceID, CustomerID));

(SourceID int NOT NULL PRIMARY KEY CLUSTERED,
CustomerID int NOT NULL PRIMARY KEY CLUSTERED,
