Explanation

When a firewall must filter traffic between multiple subnets with different IP address ranges (LAN 192.168.101.0/24, DMZ 192.168.200.0/24, and WAN 10.0.0.0/30), the firewall must operate in routed mode. Routed mode makes the firewall a Layer 3 (IP routing) hop between subnets, allowing it to route and filter traffic across different networks. Transparent mode operates at Layer 2 and is used when the firewall must be inserted into an existing network without changing IP addressing - it cannot route between different subnets. 'Network' and 'gateway' are not valid Cisco FTD firewall modes.
