Answer is Correct
To identify which network operations might disrupt the functioning of vSphere HA, you must know which management networks are being used for heart beating and other vSphere HA communications.
On legacy ESX hosts in the cluster, vSphere HA communications travel over all networks that are designated as service console networks. VMkernel networks are not used by these hosts for vSphere HA communications. To contain vSphere HA traffic to a subset of the ESX console networks, use the allowedNetworks advanced option.
On ESXi hosts in the cluster, vSphere HA communications, by default, travel over VMkernel networks. With an ESXi host, if you want to use a network other than the one vCenter Server uses to communicate with the host for vSphere HA, you must explicitly enable the Management traffic check box.
