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.

Answer: ADE

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.
