Which two statements are true about Database as a Service (DBaaS) or about Database Schema Service in Oracle Public Cloud?

A.
With Database Schema Service, there is a separate database for each schema.

B.
With DBaaS, you get a dedicated database instance or instances.

C.
With Database Schema Service, the schema or schemas may be in the same database as other schemas that belong to other subscribers.

D.
With DBaaS, you cannot decide when to patch the database home.

E.
With Database Schema Service, the schema may be in an Oracle Database 12c pluggable.

Explanation:
Database Schema Service uses schema isolation to implement multi-tenancy, which allows full transparency while still providing efficient use of database

resources. The Oracle Database is, at its core, a multiuser system for sharing data, so Database Schema Service simply uses the capabilities built up for the Oracle
Database to share resources among multiple Database Schema Service customers.
