In the firewall hot standby scenario, which of the following status information can be backed...

In firewall hot standby (HRP - Hot Standby Routing Protocol) mode, certain data can be synchronized between the active and standby firewalls to ensure uninterrupted service.

The following data is backed up:

✅ Server mapping table: Contains information about NAT mappings and other session mappings.

✅ AAA user table (excluding the default user admin): Ensures that authenticated users do not need to re-authenticate in case of failover.

✅ Session table: Ensures that existing connections remain active when switching to the standby firewall.

❌ Dynamic MAC address table is NOT backed up because it is dynamically learned and not relevant to firewall session synchronization.
