Which statements are true about LIFs used for cluster peer relationship?

• A. The LIFs must use the default intercluster service policy.
• B. At least one LIF per node is required on each cluster.
• C. Both statements are true.
• D. Neither statement is true.

Answer: (C)

Intercluster LIFs are the network endpoints that carry the traffic for a cluster peer relationship between ONTAP clusters. These LIFs must use the intercluster service policy so that the intercluster traffic is treated and routed correctly, stays isolated from data traffic, and benefits from the appropriate failover and path selection behavior for peer communications. The default intercluster policy provides the standard, supported configuration for this traffic, making it the correct choice in typical deployments. Having at least one intercluster LIF on each node in every cluster ensures that every node can participate in the peering relationship. This per-node presence provides redundancy—if some paths or nodes fail, other nodes’ LIFs can maintain the intercluster connection—and guarantees there’s always a reachable intercluster endpoint on each cluster for reliable communication with its peer. Because both of these conditions are required for a robust and maintainable cluster peer setup, both statements are true.
