Autonomous database - export / import data

Content

Hi.

I see these ways of exporting and importing data from/to autonomous database.

1. Classic old exp/imp utilities.

2. Expdp / impdp. In this case an administrator should be able to access test server file system to upload DB dump, or mount some NFS storage?

3. DB <-> SQL file.

4. Other ways ?

Question begins with my "Always free" test database, but can be expanded for all sort of cloud activities.
