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 applications.
What should you create for each application?
A.
Synonyms
B.
Common table expressions
C.
Views
D.
Temporary tables

Why not A?
Views is a better choice, because you need to prevent the applications from accessing the table directly. A synonym is just another name for an object, and usually used for remote tables, database links, objects in other schemas.
