Question

Quizplus · Accepted Answer

MAC layer firewalls, also known as bridge firewalls, work at the data link layer of the OSI model and filter traffic based on MAC addresses. They can be used to isolate and secure network segments and are commonly used in Wireless LANs (WLANs) and Virtual LANs (VLANs). Option B, Circuit gateway, is not a valid type of firewall. Option C, Application gateways, also known as proxy firewalls, operate at the application layer of the OSI model and filter traffic based on specific protocols or applications. Option D, Packet filtering, operates at the network layer and filters traffic based on IP addresses and other characteristics of individual packets.
