Explanation:
MERGE with Incremental Loads The change data capture functionality that is new in SQL Server
2008 makes it easier to perform incremental loads reliably to a data warehouse. As an alternative to
using parameterized OLE DB Command transformations to perform the inserts and the updates, you
can use the MERGE statement to combine both operations.

NO.5 You administer a Windows Azure SQL Database database named Inventory that contains a
stored procedure named p_AddInventory.
Users need to be able to SELECT from all tables in the database and execute the stored procedure.
You need to grant only the necessary permissions.

A. Add EXECUTE AS OWNER to the stored procedure. Add all users to the db_datareader role.
B. Add all users to the db_datawriter role. Add all users to the db_datareader role.
C. Create a new database role. Grant EXECUTE permission on p_AddInventory to the newrole. Add
all users to the role. Add all users to the db_datareader role.
D. Create a new database role. Grant EXECUTE permission on p_AddInventory to the new role.

Explanation:
In SQL Server you can define the execution context of the following user-defined modules: functions
(except inline table-valued functions), procedures, queues, and triggers. By specifying the context in
which the module is executed, you can control which user account the Database Engine uses to
validate permissions on objects that are referenced by the module. This provides additional
flexibility and control in managing permissions across the object chain that exists between
user-defined modules and the objects referenced by those modules. Permissions must be granted to
users only on the module itself, without having to grant them explicit permissions on the referenced
objects. Only the user that the module is running as must have permissions on the objects accessed
by the module.
Reference: EXECUTE AS Clause (Transact-SQL) You administer a Microsoft SQL Server 2012 database.

NO.6 ----
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.
