Refer to the exhibit.
***Exhibit is Missing***
Which Information Is passed between the active and standby Cisco ASA firewalls over interface m0/0? (This exhibit asking for LAN failover Link features on ASA Failover)
A. TCP connection status
B. network link status
C. ARP table
D. SIP signaling session
“B” is correct answer due to following things:
e0/3 interfaces were configured as Stateful Failover Link
m0/0 interfaces were configured as Failover Link
According Cisco manual through Failover link devices exchange this information:
The unit state (active or standby)
Hello messages (keep-alives)
Network link status!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
MAC address exchange
Configuration replication and synchronization
https://www.cisco.com/c/en/us/td/docs/security/asa/asa90/configuration/guide/asa_90_cli_config/ha_overview.html#55287
Not sure about this one, also because there is a key mismatch between FW1 & FW2:
FW1
failover lan key key1
blabla
FW2
failover lan key rack
blabla
If it would be statefull failover, the A and C would be correct – bacause through the stafull failover even ARPs are exchanged.
B. network link status, is wrong because…. the failover link is e0/3
The following information is communicated over the failover link:
• The unit state (active or standby)
• Hello messages (keep-alives)
• Network link status
• MAC address exchange
• Configuration replication and synchronization
The correct answer is, A. TCP connection status because….
For Stateful Failover, the following state information is passed to the standby ASA:
TCP and UDP connections and states.
https://www.cisco.com/c/en/us/td/docs/security/asa/asa95/configuration/general/asa-95-general-config/ha-failover.pdf
This one is tough because it doesn’t state in the question whether this is a Stateful or Stateless failover.
Unless somebody posts the whole question with exhibit which specifically states Stateful failover, I am going to lean towards B – Network Link Status.
Just like you posted above:
Failover Link Data
The following information is communicated over the failover link:
• The unit state (active or standby)
• Hello messages (keep-alives)
• Network link status
• MAC address exchange
• Configuration replication and synchronization
The interface mentioned in the exhibit as “failover link STATE e0/3”
I would go with AngelG with option “A” is the correct answer
