6: On the diagram produced in answer to Question 5, show the capacity of each link in the network and provide a note against each link of its contention ratio.
7: On the diagram produced in answer to Question 5, colour and distinguish the switches and routers and for each device provide a note of its backplane capability.
9.x: On the diagram produced in answer to Question 5 colour in the firewall(s) (or other security devices).
