Question

Which three statements about firewall modes are correct? (Choose three.)

Options

AA firewall in routed mode has one IP address.
BA firewall in transparent mode has one IP address.
CIn routed mode, the firewall is considered to be a Layer 2 device.
DIn routed mode, the firewall is considered to be a Layer 3 device.
EIn transparent mode, the firewall is considered to be a Layer 2 device.
FIn transparent mode, the firewall is considered to be a Layer 3 device.

Explanation

In transparent (Layer 2) mode, the firewall acts as a 'bump in the wire'-it bridges traffic between two network segments without routing it. It requires only a single management IP address and is invisible to connected routers. In routed (Layer 3) mode, the firewall acts as a full Layer 3 hop with an IP address on each active interface, and routing occurs between those interfaces. Statement A is false because a routed-mode firewall has an IP address per interface. Statement C is false because routed mode is Layer 3, not Layer 2. Statement F is false because transparent mode is Layer 2, not Layer 3.
