Network fault tolerance

We have two NICs on each MapR node, and MapR provides application level NIC bonding (this is great!). However, when one interface that is bound to the hostname fails, access from other nodes seems to be lost, and the node will be 'critical' on the Control Center dashboard even if another interface is still alive. Is this means that MapR provides load-balancing but doesn't provide NIC fault tolerance?

Likewise, in case that each server is connected to multiple networks but all interfaces which are bound to the node's hostnames are connected to a single switch, could it be a single-point-of-failure?
