To increase fault-tolerance, the security administrator for Corp has installed an active/passive firewall cluster where the seco
nd firewall is held in reserve in case of primary firewall failure. 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) All packets are traversing the passive firewall causing the connections to be dropped.
(B) The heartbeat between the firewalls is not enabled.
(C) Inbound packets are traversing the active firewall and return traffic is being sent through the passive firewall.
(D) All packets are traversing the active firewall causing the connections to be dropped.
