Assuming Auto-MDIX is not supported, which of these devices would require a crossover cable when connecting to a router?

A) Switch
B) Hub
C) Bridge
D) Router
E) Host (PC)

D, E
Explanation: D) The hub, bridge, and switch are all pinned the same, and routers and hosts are all pinned the same. Connections to devices that are pinned differently require a straight-through cable, and connections to devices that are pinned the same require a crossover cable; that is, router to switch (straight), router to router (crossover).
