Which two types of IP addresses should be registered with DNS?

You are setting up IP addresses for your Oracle Clusterware-based cluster. Which two types of IP
addresses should be registered with DNS?

A.
Public IP address

B.
Private IP address

C.
VIP address

D.
Storage IP address

Explanation:
In an Oracle Clusterware configuration, there must be a minimum of two network
connections. One connection is for the public network interface on which users and application
servers connect to access data on the database server, and the other connection is for the private
network interface between the nodes in the cluster.
