The cluster interconnect LIFs are created on which type of interface?

• A. on a virtual NIC
• B. on a dedicated management interface
• C. on a physical port
• D. on a loopback

Answer: (C)

Cluster interconnect traffic needs a real network path between nodes, so interconnect LIFs must be created on physical ports. Traffic for node-to-node coordination travels over the physical network, requiring tangible NICs and switches to provide a deterministic path with proper bandwidth and low latency. A virtual NIC would place the LIF on a virtualized layer, which isn’t how the cluster interconnect operates. A dedicated management interface is reserved for management traffic and isn’t intended for the inter-node heartbeat and state communications. A loopback is internal to the host and cannot reach other nodes, so it cannot carry inter-cluster traffic. Therefore, the interconnect LIFs are configured on physical ports.
