Which two statements are true about the Database as a Service (DBaaS) instances and Oracle database instances that are provided by Oracle Public Cloud?

A.
A DBaaS instance Virtual Image always provides a pre-created Oracle database.

B.
An Oracle database instance that is provided as part of DBaaS runs a different executable than would be run with the same version and release of Oracle
Database on private premises.

C.
A DBaaS instance Virtual Image always provides a Linux virtual machine.

D.
A DBaaS instance Virtual Image requires customers to install their preferred version on the Oracle database software.

E.
Multiple Oracle database instances can run in a DBaaS instance on Oracle Public Cloud.

Explanation:
C: A During DBaaS instance Virtual Image installation a Linux instance is created and a tarball is dropped into a staging area. The database is not provisioned. The
file system is not prepared. The network ports are not configured and enabled. True, the virtual instance creation only takes a few minutes but all we are doing is
provisioning a Linux instance and copying a tarball into a directory.
E: Oracle Database Cloud Service enables Database Containerization. Oracle Database 12c includes the Oracle Multitenant option for managing Pluggable
Databases.
Incorrect Answers:
A: When you create a database deployment on Oracle Database Cloud Service using the Virtual Image service level, Oracle Database is not automatically installed,
nor is a database created. You must perform these steps manually after the deployment is created.
B: Oracle Database Cloud Service provides dedicated database instances with Oracle Database 11g, 12.1 and 12.2, with your choice of Standard, Enterprise, High
Performance, or Extreme Performance packaging.
D: To create a database on a deployment using the Virtual Image service level, you perform these tasks:
1. Create storage volumes for the Oracle Database software and for the database files, and then format and mount them.
2. Stage the Oracle Database software on the mount point you created for it.
3. Create a database and start the database instance.
4. Start the listener for the database instance.
5. Create Oracle Compute Cloud Service security rules to permit access to services of the database from outside the Oracle Cloud.
