What is exchanged through the HA2 link?
The HA2 link is used for session synchronization between devices in a high availability pair. This includes synchronizing sessions, forwarding tables, IPSec security associations, and ARP tables. The data flow on the HA2 link is unidirectional, typically from the active device to the passive device, ensuring that both devices maintain the same state information for failover purposes.
Correct: C "Data Link—The HA2 link is used to synchronize sessions, forwarding tables, IPSec security associations and ARP tables between devices in an HA pair. Data flow on the HA2 link is always unidirectional (except for the HA2 keep-alive); it flows from the active device to the passive device." https://docs.paloaltonetworks.com/vm-series/9-0/vm-series-deployment/set-up-the-vm-series-firewall-on-aws/high-availability-for-vm-series-firewall-on-aws/ha-links#:~:text=%E2%80%94The%20HA1%20link%20is%20used,port%20is%20used%20for%20HA1.
correct is C
Correct answer is C
The HA2 link is used to synchronize sessions, forwarding tables, IPSec security associations and ARP tables between firewalls in an HA pair. Data flow on the HA2 link is always unidirectional (except for the HA2 keep-alive); it flows from the active or active-primary firewall to the passive or active-secondary firewall. The HA2 link is a Layer 2 link, and it uses ether type 0x7261 by default. Ports used for HA2—The HA data link can be configured to use either IP (protocol number 99) or UDP (port 29281) as the transport, and thereby allow the HA data link to span subnets.
