Host1-------device1-------device2---------device3---------host2
Host1 and host2 are on the same subnet. E.g. 192.168.1.0/24
Repeater = layer 1
Bridge = layer 2
Switch = multiport bridge = layer 2
Each of these three devices, or any combination thereof, would provide the
desired result, i.e. flawless communication between end hosts on the same
subnet.
Everyone I have talked to about the Lab says the same thing - know it cold -
what happens as data moves from here to there. Know it with each layer, each
device, each protocol. They also say "think!"

Chuck,
OK, I'll bite. In this case all three devices would have to be bridges.
For example, if Device 1 received a packet sent by Host A addressed to Host
B and ip routing was turned on then, since they are on the same subnet,
Device 1 would reasonably expect Host B to be on the same connected subnet
as Host A and would not take any action to route the packet.
