The security administrator has just installed an active\passive cluster of two firewalls for enterprise
perimeter defense of the corporate network. Stateful firewall inspection is being used in the firewall
implementation. There have been numerous reports of dropped connections with external clients.
Which of the following is MOST likely the cause of this problem?

A.
TCP sessions are traversing one firewall and return traffic is being sent through the secondary
firewall and sessions are being dropped.

B.
TCP and UDP sessions are being balanced across both firewalls and connections are being
dropped because the session IDs are not recognized by the secondary firewall.

C.
Prioritize UDP traffic and associated stateful UDP session information is traversing the passive
firewall causing the connections to be dropped.

D.
The firewall administrator connected a dedicated communication cable between the firewalls in
order to share a single state table across the cluster causing the sessions to be dropped.
