Detailed Solution for Test: Firewalls - Question 1

Detailed Solution for Test: Firewalls - Question 2

Answer: a
Explanation: Most network layer firewalls can operate as stateful or stateless firewalls, creating two subcategories of the standard network layer firewall. Stateful firewalls have the advantage of being able to track packets over a period of time for greater analysis and accuracy — but they require more memory and operate more slowly. Stateless firewalls do not analyze past traffic and can be useful for systems where speed is more important than security, or for systems that have very specific and limited needs. For example, a computer that only needs to connect to a particular backup server does not need the extra security of a stateful firewall.

There are two primary categories of application firewalls, network-based application firewalls and host-based application firewalls.
