Answer to Question 1

D

Answer to Question 2

A stateful packet inspection (SPI) firewall combines the advantages of packet filtering with the advantages of application filtering, resulting in compromise between the two. SPI firewalls are not as fast as packet filtering firewalls or as secure as application layer firewalls, but provide some of the benefits of both. A standard packet filtering firewall examines each packet in a communication stream, evaluating that packet's header information, but not its content, and either passes or drops the packet based upon filtering rules. SPI firewalls, on the other hand, can examine packet contents as well. Also, SPI firewalls continuously evaluate packets to determine if a valid connection has been opened for them from inside of the network. If there is a valid connection for the packet or packet stream the SPI firewall lets the packet through, otherwise the packet is dropped.
