What happens to the broadcast domain when multiple Cisco LAN switches are interconnected?

• A. The broadcast domain remains limited to each switch
• B. The broadcast domain is eliminated entirely
• C. The broadcast domain expands to all switches
• D. The broadcast domain halves in size with each connection

Answer: (C)

When multiple Cisco LAN switches are interconnected, the broadcast domain expands to include all switches and the devices connected to them. In a switched network, switches forward broadcast packets to all ports except the one on which they were received. Therefore, when switches are connected to each other, the devices on all interconnected switches are part of the same broadcast domain. This allows devices throughout the network to communicate directly with each other through broadcast messages. The concept of broadcast domains is crucial in understanding how data packets are transmitted over a network. Unlike routers, which separate broadcast domains, switches do not perform this function. As a result, any broadcast from a device connected to one switch will reach all devices attached to other interconnected switches. This is important for services that rely on broadcast communication, such as ARP, DHCP, etc., as it allows these services to function properly within a larger network environment. In summary, interconnecting switches results in a unified broadcast domain that allows for efficient communication across the entire switched network.
