With active/standby failover, what happens if the standby Cisco ASA does not receive three
consecutive hello messages from the active Cisco ASA on the LAN failover interface?

A.
The standby ASA immediately becomes the active ASA.

B.
The standby ASA eventually becomes the active ASA after three times the hold-down times
interval expires.

C.
The standby ASA runs network activity tests, including ARP and ping, to determine if the active
ASA has expired.

D.
The standby ASA sends additional hellos packets on all monitored interfaces, including the LAN
failover interface, to determine if the active ASA has failed.

E.
Both ASAs go to the “unknown” state until the LAN interface becomes operational again.
