A. Port number

B. DNS lookup number

C. Source IP address

D. WINS server NetBIOS name

E. Destination IP address

Explanation: TCP uses sequential bits of data called packets for sending data. Headers within these packets contain information for routing. This information includes the source address, destination address, and the appropriate ports for both. Firewalls use port numbers to determine if the packet should be forwarded or dropped.

& Domain 2.6: Define the function of TCP/UDP ports. Identify well-known ports.

& Domain 3.8: Identify the purpose, benefits and characteristics of using a firewall.
