Hello Pichai
Actually, the ASA can be configured in an Active/Active failover arrangement. There is not yet a lesson for this, but it may be added in the future. More information about it can be found at the following Cisco documentation:
https://www.cisco.com/c/en/us/td/docs/security/asa/asa90/configuration/guide/asa_90_cli_config/ha_active_active.html
I hope this has been helpful!
