Which of the following actions should you take?

Topic 2, Scenario 2
Application Data
You are employed as a database administrator at ABC.com. The ABC.com network consists of a
single domain named ABC.com.
A current ABC.com application is configured to host item information, which is saved in XML
format, will be transformed into mechanical drawings for engineering purposes. This process will
be facilitated by making use of a newly developed Microsoft .NET Framework assembly, named
ProcessItems.dll, which was generated via the use of the ProcessItem.es source code file.
ProcessItems.dll includes a single class, named ProcessItem, and a method, named Transform().
Furthermore, the drawings are to be stored as illustrations.
You are informed that every XML should include a single item with a root element, named Item.
You have generated a schema for the items xml, named Production.ItemSchema. The items xml is
configured to have a product type of eleven characters.
•The first five characters reference the category of the product.
•The last six characters refer to the subcategory of the item.
You are planning to create a new database on a server running SQL Server 2012 to support the
application. You have, however, detected that the application includes a number of performance
and security concerns. You are planning to create two tables, named Items and
ManufacturingStages. The Items table will include the following columns:
•ItemID, which is configured as the primary key.
•ItemType
•ItemName
•CreationDate
•ItemSpecifics
The ManufacturingStages table will include the following columns:
•ManufacturingStagesID
•ItemID
•Manufacturing Code
A sequence, named Production.ItemID_Seq, will also be added. You are also planning to generate
a certificate, named ABCItemsCert, in master and a certificate, named ABCDBCert in
ABCItemsCert.
ABC.com wants an application to be configured to perform dynamic T-SQL statements against the
new database.
Application Prerequisites
You are required to make sure that all stored procedures are signed, and that the original item
specifics are stored in the database. You also have to make sure that an XML schema is
employed to authenticate the item specifics, and that the assembly is accessible via T-SQL
commands.
You have been informed that a table-valued function should be created to search products by
type, and that dynamic T-SQL statements should be converted to stored procedures. You have
also been informed that indexes should be boosted from time to time according to their
fragmentation.
You need to configure the highest level of encryption to safeguard backups. Furthermore, you
have to make sure that the manufacturing stages stored in the ManufacturingStages table relates
to an item via an identical identifier employed by the Items table
Lastly, you have to make sure that the consumption of disk space and administrative effort is kept
to a minimum.
********************************************************

You are in the process of planning the ManufacturingStages table. You are preparing to write the
necessary code to define the ItemID column as per the prerequisites.
Which of the following actions should you take?

A.

B.
You should consider creating a foreign key relationship.

C.
You should consider creating a unique key relationship.

D.
You should consider creating a primary key relationship.
