Answer 1

The correct option is (c) You can do load balancing

Explanation: DMZ stands for De-Militarized Zone. In a topology with a single firewall serving both internal and external users (LAN and WAN), it acts as a shared resource for these two zones. So load balancing can be done by adding another firewall.
