d. None of the above.
105. What is an application-layer firewall?
a. A firewall that examines the content of packets to identify and block specific types of traffic.
b. A firewall that blocks all network traffic unless it is specifically allowed by a rule.

d. None of the above.
106. What is a proxy firewall?
a. A firewall that sits between a client and a server and mediates network traffic between them.
b. A firewall that blocks all network traffic unless it is specifically allowed by a rule.
