Quesion 2 - Diagram not given

Question 3 -  Contains two NICs

Explanation - In firewalls, dual homed host is a system that is fitted with two Network Interaces(NICs) for providing secure access.

Question 4 - UTM

Explanation - UTM ( Unified Threat management ) is  capable of packet filtering, content filtering, intrusion detection, proxy, and application layer filtering.

Question 5 - software firewall

Explanation - software firewall is most often used on individual computers whereas hardware firewalls require expert setup.

Question 6 - Filtering by protocol being used

Explanation - generation one firewalls inspect source IP address,destination IP address,source and destination ports,and protocol like TDP,UDP etc to filter the traffic.

Question 7 -  Stateless

Explanation - the earliest firewalls were only capable stateless filtering that uses some predetermined rules to filter and they store no information on connection state.

Question 8 - Block incoming unsolicited traffic

Explanation - firewalls were originally conceived to block all unwanted incoming traffic.

Question 9 - Stateful

Explanation - Stateful firewall moniters the full state of the active network connections and is constantly analyzing the complete context of traffic and data packets.

Question 10 - Virtual firewall

Virtual firewall refers to a software firewall places on a dedicated server to create an internal hardware firewall.
