NEW QUESTION # 92
Which two are true about common objects? (Choose two.)

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

Answer: A,F

Explanation:
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.
A local user can own a common object. Also, a common user can own a local object, but only when the object is not data-linked or metadata-linked, and is also neither a metadata link nor a data link.

NEW QUESTION # 93
