specifying the correct category of cable in the design
minimizing the number of switches in the design
maximizing the use of hubs
* minimizing the delay between distant stations

14 To make sure timing limitations are not violated when implementing a 10 Mbps Ethernet network involving hubs or repeaters, a technician should adhere to which rule?

the 4-5-3 rule
the 6-4-2 rule
the 3-4-5 rule
