Assuming there are open connections through an active system's NAT and a failover occurs, by default, what happens to those connections?

By default, when a failover occurs in a system with NAT-enabled connections, all open connections will be lost. Connection mirroring, which would preserve connections, is an optional feature and must be configured in advance. Without this specific setup, the system does not maintain open connections during a failover.
don't think that's correct. By default - lost
I'm Thinking same that.
isn't E more accurate?
I think it is E. Connection mirroring is an optional feature of the BIG-IP system, designed to ensure that when failover occurs, in-process SNAT connections are not dropped. You can enable mirroring on each SNAT that is associated with a floating virtual address. On the Main tab, click Local Traffic > Address Translation . The SNAT List screen displays a list of existing SNATs. In the Name column, click the relevant SNAT name. For the Stateful Failover Mirror setting, select the check box. Click Update. In addition to enabling connection mirroring on a SNAT, you must also specify a mirroring IP address on this device. Other traffic groups in the device group use this address when mirroring their connections to this device.

mirroring is optional in HA configuration. so by default all connection will be lost ( reponse A )
