Explanation
An unmanaged switch connects multiple devices and, by default, places all ports in a single broadcast domain, ensuring broadcast frames are forwarded to every network port within that domain.
Common mistakes.
- B. A hub repeats all incoming signals to every other port, effectively 'broadcasting' all traffic, but an unmanaged switch is a more modern and intelligent device that performs this function specifically for broadcast traffic while efficiently forwarding unicast frames.
- C. A firewall is a security device that filters network traffic based on security rules, not primarily for connecting multiple devices or broadcasting to ports.
- D. A cable modem provides internet connectivity from a cable provider and typically has only a few Ethernet ports, not designed for connecting multiple internal network devices within a local network.
