In SSCP network Part 2 you state that Dual Homed is when you have a LAN and a DMZ behind the firewall. I have always understood dual homed or multi homed as referring to two or more ISPs that are configured with BGP or some other protocol. So for the exam if they refer to dual homed it is for a DMZ LAN configuration?

When they mention dual homed, they are talking about a network device with two (or more than two in the case of multi-homed) network cards installed. One of the main reasons to have more than one network interface card is to separate traffic from your LAN and your internet facing servers (in the DMZ) by putting them on separate networks (one per interface). There's one final step to the process and that's to implement ACLs that control traffic going into and out of both the DMZ and LAN.
Hope this helps,

In the context of SSCP, I believe that you'll see the later is more likely to be true, it's probably more for the DMZ LAN Configuration. Adam is more likely to address the topic in the way you're likely to see it on the exam.
