B. Common users connected to a PDB can exercise privileges across other PDBs.
C. Local users cannot use local system privileges on the schema of a common user.
D. System privileges apply only to the PDB in which they are used.

1Z0-060 番号   1Z0-060 解答   
Explanation:
A, Not D: In a CDB, PUBLIC is a common role. In a PDB, privileges granted locally to PUBLIC enable all
local and common users to exercise these privileges in this PDB only.
C: A user can only perform common operations on a common role, for example, granting privileges
commonly to the role, when the following criteria are met:
The user is a common user whose current container is root.
The user has the SET CONTAINER privilege granted commonly, which means that the privilege applies
in all containers.
The user has privilege controlling the ability to perform the specified operation, and this privilege has
been granted commonly
Incorrect:
Note:
* Every privilege and role granted to Oracle-supplied users and roles is granted commonly except for
system privileges granted to PUBLIC, which are granted locally.
