ISO or virtual appliance

Hmm...can you be please more elaboration. I mean in that case how the IP
addresses or A records will be removed as the one CNAME entry is pointed to
2 hostsnames. Or would you want to monitor www.lb.example.com instead of
www.example.com and keep example.com as a static entry?

I am sorry I am bit confused here.
