Which statement describes the requirements for the network interface names, such as eth0, in
Oracle Clusterware?
A.
Only the public interface names must be the same for all nodes.
B.
Only the private interface names must be the same for all nodes.
C.
Both the public interface name and the private interface name must be the same for all nodes.
D.
Both the public interface name and the private interface name can vary on different nodes.
E.
Only the private interface names can be different on different nodes.
F.
Only the public interface names can be different on different nodes.
Explanation:
Checking Network Requirements
Each node must have at least two network interface cards (NICs).
Interface names must be the same on all nodes.
Public NIC must support TCP/IP and Private NIC UDP.
Public IP must be registered in the domain name server (DNS) or the /etc/hosts file.
# cat /etc/hosts
##### Public Interfaces eth0 (odd numbers)####
xxx.xxx.100.11
host01.example.com host01
xxx.xxx.100.13
host02.example.com host02
IF GNS is used, the Cluster GNS address must be registered in the DNS.
Prevent public network failures when using NAS devices or NFS mounts by starting the Name
Service Cache Daemon.
# /sbin/service nscd start

Both private and public interface name have to be the same on all nodes
So C is correct

If you use OUI to install Oracle Grid Infrastructure, then the private network connection names associated with the private network adapters must be the same on all nodes.
If you use OUI to install Oracle Grid Infrastructure, then the public network connection names associated with the public network adapters for each network must be the same on all nodes
