Review the exhibit and type the IP address of the member serving as the pivot machine in the space below.

Can we see the exhibit?

no, because you are pinging the VIP so the pivot member will always own that, hence arp response will be from the pivot.

=> In this mode a single cluster member, referred to as Pivot, is associated with the cluster’s virtual IP addresses

Load Sharing Unicast Mode

Load Sharing Unicast mode provides a Load Sharing solution adapted to environments where Multicast Ethernet cannot operate. In this mode a single cluster member, referred to as Pivot, is associated with the cluster’s virtual IP addresses, and is thus the only member to receive packets sent to the cluster. The pivot is then responsible for propagating the packets to other cluster members, creating a Load Sharing mechanism. Distribution is performed by applying a decision function on each packet, the same way it is done in Load Sharing Multicast mode. The difference is that only one member performs this selection: any non-pivot member that receives a forwarded packet will handle it, without applying the decision function. Note that non-pivot members are still considered as “active”, since they perform routing and Firewall tasks on a share of the traffic (although they do not perform decisions.).

Even though the pivot member is responsible for the decision process, it still acts as a Security Gateway that processes packets (for example, the decision it makes can be to handle a packet on the local machine). However, since its additional tasks can be time consuming, it is usually assigned a smaller share of the total load.

When a failover event occurs in a non-pivot member, its handled connections are redistributed between active cluster members, providing the same High Availability capabilities of New High Availability and Load Sharing Multicast. When the pivot member encounters a problem, a regular failover event occurs, and, in addition, another member assumes the role of the new pivot. The pivot member is always the active member with the highest priority. This means that when a former pivot recuperates, it will retain its previous role.
