11G has a new feature called Invisible Indexes. An invisible index is invisible to the optimizer as

existing sql statements or we can test the effect of dropping an index without dropping it.

D: The database internally uses standard file system interfaces to create and delete files as needed
for the following database structures:
Tablespaces Redo log files Control files Archived logs Block change tracking files Flashback logs RMAN
* Using Oracle-managed files simplifies the administration of an Oracle Database. Oracle-managed
files eliminate the need for you, the DBA, to directly manage the operating system files that make up
an Oracle Database. With Oracle-managed files, you specify file system directories in which the
database automatically creates, names, and manages files at the database object level. For example,
you need only specify that you want to create a tablespace; you do not need to specify the name and
path of the tablespace's datafile with the DATAFILE clause.

user before the common user can grant privileges to other users.
Answer: A,C,E

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
* 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.
