• B. They can be only metadata-linked in an application container.
• C. They can exist in user-defined schemas only in application containers.
• D. They can exist in CDB$ROOT and an application root.
• E. They can be extended data-linked in CDB$ROOT.
• F. They can be created only in an application root.

 

answer: D F

 

READ THIS:
A common object is defined in either the CDB root or an application root, and can be referenced using metadata links or object links. A local object is every object that is not a common object.

Database-supplied common objects are defined in CDB$ROOT and cannot be changed. Oracle Database does not support creation of common objects in CDB$ROOT.

You can create most schema objects—such as tables, views, PL/SQL and Java program units, sequences, and so on—as common objects in an application root. If the object exists in an application root, then it is called an application common object.
ACCORDING THE LECTURE, CORRECT ANSWERS ARE: DF
D: they can exist in CDB$ROOT and application root.
F: they can be created only in application root
