which three choices does it offer when installing the Oracle Database 11g Release 2 software?

Once OUI recognizes a set of nodes in a cluster, which three choices does it offer when installing
the Oracle Database 11g Release 2 software?

A.
You can only install the Oracle Database with the RAC option on selected nodes.

B.
OUI forces you to configure ASM for shared storage before proceeding.

C.
You can install the Oracle Database as a single instance or with the RAC option on all the
nodes.

D.
You can install the Oracle Database as a single instance or with the RAC option on selected
nodes.

E.
You can install Oracle RAC One Node.

Explanation:
B, D: Complete the prerequisite tasks for converting to an Oracle RAC database:
Oracle Clusterware and Oracle Database software is installed on all target nodes.
Oracle Clusterware is started.
(D) The Oracle Database binary is enabled for Oracle RAC on all target nodes.
(B) Shared storage is configured and accessible from all nodes.
User equivalency is configured for the operating system user performing the conversion.
Enterprise Manager agents are configured and running on all nodes, and are configured with the
cluster and host information.
The database being converted has been backed up successfully.
E: Installing Oracle RAC One Node is available starting with Oracle Database 11g Release 2
(11.2.0.2).
Note:
* By default, the standard Oracle Database 11g software installation process installs the Oracle
RAC option when OUI recognizes that you are performing the installation on a cluster.
