- Stateful active/standby failover
- Global Access Control Lists
- Cluster load balancing
- Server load balancing
The correct answers are 1, 3, and 4.
With Stateful Active/Standby failover, VPN users do not have to reconnect or reauthenticate should the Active ASA fail. With Cluster Load balancing a group of ASAs will work cooperatively to share the VPN load. With Server Based Load Balancing a Cisco Application Control Engine (ACE) is installed in a Cisco 7600/6500 series device and is used as an SSL VPN front end to multiple ASA servers running in parallel.
