Which two topologies are using the correct type of twisted-pair cables?
Which two topologies are using the correct type of twisted-pair cables? (Choose two.)
Devices of the same layer are connected by crossover cable, while devices of different layers are connected by straight-through cable.
Router—–Crossover—–Router
Router—–Crossover—–PC
Router—–straight-through—–Switch
Switch—–straight-through—–PC
Switch—–Crossover—–Switch
Devices of the same layer are connected by crossover cable, while devices of different layers are connected by straight-through cable.
Router—–Crossover—–Router
Router—–Crossover—–PC
Router—–straight-through—–Switch
Switch—–straight-through—–PC
Switch—–Crossover—–Switch
Yes and no. PCs and hubs are layer one devices. Switches are layer two. Routers are layer three. Devices of the same layer are connected with crossover cables and devices between layers are connected via straight-through cables.
The images show
Pc to Switch which uses a straight-through cable (layer 1 to layer 2)
Router (console port) to PC which uses a rollover cable (layer 3 (con) to layer 1)
Router to switch which uses a straight-through cable (layer 3 to layer 2)
Router (fast Ethernet port)to PC uses a crossover cable (layer 3 (fa)to layer 1)
Switch to switch uses a crossover cable (layer 2 to layer 2)
Otherwise B and C would be true as well as D. B is not true in this case because you need a rollover instead of a crossover.
B, E
I have the same idea.
