My problem statement was:
my box is ASA 5585x, since this model have G0/0 - 0/7 sufficient interface, so i no need to do sub-interface for the context.
a. is it cumpulsary must have the admin context on A-A deployment?
it mention that "The Admin Context is not restricted and can be used as any other security context."
Can i just exclude this admin context?
b. Refer to my config snipet, can i just allocate management interface to the admin context, instead of allocate it to any inside/outside interface?
c. Is it a good practice not to use the same interface to do LAN failover and stateful failover? I facing the problem of "ghost image" when i enable the multiple mode and both LAN/stateful failover on same interface.
P.S: Config snipet
