Your question:

What is the advantage of breaking up a broadcast domain? Companies can save money by using less expensive cables. Network clients can access the internet. Network clients receive fewer overall messages. Network traffic can be filtered based on MAC addresses.

Reducing Broadcast Messages Answer and Explanation

• Network clients can access the internet: This is more a result of having a network, not specifically related to breaking up a broadcast domain.

• Network traffic can be filtered based on MAC addresses: While filtering is possible at layer 2, it's more effective with segmentation based on IP addresses and layer 3 devices like switches and routers. Breaking up the domain helps reduce overall broadcast traffic, simplifying filtering needs.

So, while the other options have some truth to them, reducing overall message volume for network clients is the main advantage of breaking up a broadcast domain. It improves performance, security, and manageability within your network.
