Answer A is correct - Cluster requires public IP for each node.. 8.4 feature consists of adding the unique public IP (one per cluster node) to each controller configuration in the cluster group profile

Selected Answer: A
Clustering is not recommended for MCs that terminate RAP connections because clustering would require each cluster member to have a public IP address to provide to the RAPs. VRRP-based redundancy will serve the needs for a single site (LMS backup would serve the needs if the customer had a second data center connected at Layer 3 and wanted to deploy the backup controller there)
