D - Correct MAC masquerading Purpose: You should consider using this procedure under the following conditions: -You want to minimize Address Resolution Protocol (ARP) communication or dropped packets during traffic group failover events. -You want to improve reliability and failover speed in lossy networks. -You want to improve interoperability with switches that are slow to respond to gratuitous ARP requests. https://my.f5.com/manage/s/article/K13502
