1. Which of the following is NOT a function of a firewall? a. Blocks or forwards packets based on source and destination address and TCP port b. Blocks or forwards packets based on source and destination address and UDP port c. Examines packet data for worms, viruses, malware, etc. and blocks a stream if it contains malicious content d. Converts Ethernet packets to Token Ring or ARCnet packets e. Allows a computer inside the firewall to initiate a TCP connection to an outbound system, and then transmit data to and from that system, while preventing an outbound system from initiating a TCP connection to an internal host. Solution The correct option is d. Converts Ethernet packets to Token Ring or ARCnet packets Since Ethernet is one network and another is token ring then to communicate between these two work stattions is possible by using bridge or gateway. Ethernet with a speed of 100Mbps and Token ring with a speed of 10Mbps. Here firewall has done nothing to work to get it working between two different networks. The firewall is either software program or hardware like Router which monitors the incoming packets for malicious code or virus or worms to infect the computer.The firewall examines packet data for unauthorized access to get control over the computer system. .
