- the amount of traffic that is currently crossing the network -the type of traffic that is crossing the network -the latency that is created by the number of network devices that the data is crossing

- the link between the switches will work at the fastest speed that is supported by both switches - the link between the switches will work as full-duplex - the auto-MDIX feature will configure the interfaces eliminating the need for a crossover cable
