How many broadcast domains are shown in the graphic assuming only the default VLAN is
configured on the switches?
A.
six
B.
two
C.
one
D.
twelve
Explanation:
There is only one broadcast domain because switches and hubs do not segment the broadcast
domains when only a single VLAN is configured. Only layer 3 devices can segment the broadcast
domains, or VLAN-capable switches where multiple VLANs are configured. By default, all ports in
a switch belong to VLAN 1 so in this case the entire network will consist of one large broadcast
domain.
