How to tell if Active/active or Active/Standby mode is configured?

Question

Folks:
I am still learning the output of my running config, but how do I tell if my firewall is set to Actve/Active or Active/Standby mode?
In addition, how do I tell if it uses regular or stateful failover mode?
Thank you

I wanted to provide this as well, since I found it and it also helped me answering my question.
This output shows Active/Active failover output.
**Note** it says PIX; however, I beleive it will be the same output for ASA.
PIX1(config-subif)#show failover
