Which statement describes how traffic flows in sessions handled by a slave unit in an active- active HA cluster?

Packets are not sent directly to the slave unit's physical MAC address for load-balanced sessions in an active-active HA setup; they are always directed to the HA virtual MAC address initially.

While packets use the HA virtual MAC, they are initially handled by the master unit, which then distributes them, rather than being sent directly to a slave unit via the HA virtual MAC for session initiation.

Packets do not arrive at both units simultaneously for session forwarding in an active-active HA cluster; the master receives the packets first and then directs the session to the appropriate unit.

In an active-active HA cluster, the master unit is responsible for receiving all incoming traffic using the cluster's virtual MAC address; it then decides whether to process a session itself or to forward it to a slave unit for processing and load balancing the session workload.
