A proxy firewall filters at _________(a) Physical layer(b) Data link l

1.	A proxy firewall filters at _________(a) Physical layer(b) Data link layer(c) Network layer(d) Application layerI got this question in class test.Enquiry is from Firewalls topic in portion Network Layer of Computer Network
Answer» The CORRECT answer is (d) APPLICATION layer For explanation: The application firewall is typically built to control all network traffic on any layer up to the application layer. It is able to control APPLICATIONS or services specifically, unlike a stateful network firewall, which is – WITHOUT additional software – unable to control network traffic regarding a specific application. There are two PRIMARY categories of application firewalls, network-based application firewalls and host-based application firewalls.
