Q3: You have configured your network to have 3 VLANs. How many broadcast domains do you have?
A. 1
B. 2
C. 3
D. 4
Correct Answer: C
Explanation:
It is important to know the difference between a collision domain and a broadcast domain. When you use Hubs, all the nodes connected to the hub will be in the same collision domain. However, when you use switches and implement VLANs, each VLAN will be in a separate broadcast domain. The packet forwarding between VLANs is achieved through the use of routing.
