What is the purpose of the optional CVM interface eth2?
The purpose of the optional CVM interface eth2 is for intra-cluster traffic between CVMs. This interface is used to handle internal communications within the cluster, ensuring that management and storage traffic are kept separate from backplane traffic, thereby optimizing network performance and stability within the cluster.
I believe answer is D I didnt find legitimate information though..
Sounds about right: in a segmented network, management traffic uses interface eth0 and the backplane traffic uses interface eth2: In a segmented network, management traffic uses interface eth0 and the backplane traffic uses interface eth2: https://www.virtualramblings.com/create-a-backplane-network/
D. eth2 is created when deploying from Foundation, but becomes active if you segment backplane traffic.

I Think it's C. The optional backplane LAN creates a dedicated interface in a separate VLAN on all CVMs and AHV hosts in the cluster for exchanging storage replication traffic. The backplane network shares the same physical adapters on bridge br0 by default but uses a different nonroutable VLAN
