Refer to the exhibit.
A network has been planned as shown. Which three statements accurately describe the areas
and devices in the network plan? (Choose three.)
A.
Network Device A is a switch.
B.
Network Device B is a switch.
C.
Network Device A is a hub.
D.
Network Device B is a hub.
E.
Area 1 contains a Layer 2 device.
F.
Area 2 contains a Layer 2 device.
Explanation:
Switches use a separate collision domain for each port, so device A must be a switch. Hubs,
however, place all ports in the same collision domain so device B is a hub. Switches reside in
layer 2 while hubs are layer 1 devices.
A, D and E
The network device in Area 1 is a switch, because every switchport is a collision domain (hence, multiple collision domains).
The network device in Area 2 is a hub, because a hub creates only one collision domain.
A switch is a layer 2 device, so answer E is also correct.
For reference: a hub is a layer 1 device
