Question

___________ tells a firewall about how to reassemble a data stream that has been divided into packets.

• A. The source routing feature
• B. The number in the header’s identification field
• C. The destination $IP$ address
• D. The header checksum field in the packet header

Answer 1

OPTION (A)

The source routing feature allows a sender of a packet to partially or completely specify the route the packet takes through the network .

It provides a path address for the packets to help the firewall to reassemble the data stream that was divided into packets. After reassembling, the firewall can then filter the stream. :)
