Why is a transparent firewall considered a "bump in the wire" or "stealth firewall"?
A. It is a bump on the wire because it filters packets at the OSI physical layer.
B. Using separate IP subnets for inside and outside interfaces, packets are inspected quietly.
C. A transparent firewall is considered a Layer 2 firewall and has no routing capabilities.
D. Transparent firewalls work in "stealth mode" by using network taps.
E. Because transparent firewalls can route between inside and outside interfaces, packets are "bumped" between them by using special firewall rule-sets.
