Here is the problem... the question ask "for the first step"...Bu

t the database MUST be in archivelog mode and de flash recovey area M

UST be enable, thus I belive the answer correct would be A and B.

Flashback Database uses its own logging mechanism, creating flash

back logs which are stored in the flash recovery area. You can only u

se Flashback Database if flashback logs are available. Therefore, you

must set up your database in advance to create flashback logs if you

want to take advantage of this feature.

The requirements for enabling Flashback Database are:

* Your database must be running in ARCHIVELOG mode, because archived

logs are used in the Flashback Database operation.

* You must have a flash recovery area enabled, because flashback logs

can only be stored in the flash recovery area.
