A network administrator is responding to a statement of direction made by senior management to implement network protection that will inspect packets as they enter the network. Which of the following technologies would be used?
A. Packet sniffer
B. Stateless firewall
C. Packet filter
D. Stateful firewall
Correct Answer: D
Explanation/Reference:
Explanation: Stateful firewall keeps track of the state of network connections (such as TCP streams, UDP communication) traveling across it. The firewall is programmed to distinguish legitimate packets for different types of connections. Only packets matching a known active connection will be allowed by the firewall; others will be rejected.
