An NGXR65 HA cluster contains two members with external interfaces 172.28.108.1 and
172.28.108.2. The internal interfaces are 10.4.8.1 and 10.4.8.2. The external cluster VIP address
is 172.28.108.3 and the internal cluster VIP address is 10.4.8.3. The synchronization interfaces
are 192.168.1.1 and 192.168.1.2. The Security Administrator discovers State Synchronization is
not working properly. The cphaprob if command output displays shows:

What is causing the State Synchronization problem?

A.
The synchronization network has been defined as “Network Objective: Cluster + 1st sync” with
an IP address 192.168.1.3 defined in the NGX cluster object’s topology. This configuration is
supported in NGX and therefore the above screenshot is not relevant to the sync problem.

B.
The synchronization interface on the individual NGX cluster member object’s Topology tab is
enabled with “Cluster Interface”. Disable this setting.

C.
The synchronization network has a cluster VIP address (192.168.1.3) defined in the NGX
cluster object’s topology. Remove the 192.168.1.3 VIP interface from the cluster topology.

D.
Another cluster is using 192.168.1.3 as one of the unprotected interfaces.
