a. Packet filtering firewall
b. Stateful packet filtering
c. Proxy firewall
d. Connection-aware firewall

Answer 1

The firewall Emilie is reviewing is a Packet filtering firewall, which makes filtering decisions based on information in the packet header.

Step-by-step explanation:

The kind of firewall that Emilie is reviewing is a Packet filtering firewall.

In packet filtering, the firewall examines each packet and makes filtering decisions based on information in the packet header, such as the source and destination IP addresses and port numbers. This type of firewall typically uses a set of rules to determine whether to allow or drop packets.

In this case, the firewall is dropping incoming packets for which the internal endpoint did not initially create the request, indicating that it is filtering packets based on their source and destination information.
