Which statement correctly describes a network hub?

• A. Forwards data only to the intended port using MAC addresses.
• B. Requires routing tables to direct traffic.
• C. Forwards incoming data to all ports (broadcast) regardless of destination.
• D. Converts digital to analog signaling.

Answer: (C)

Hubs operate at the physical layer and simply repeat any incoming signal to all connected ports. Because they don’t inspect or direct frames based on destination addresses, every device on the hub receives all traffic, which is why traffic is broadcast to all ports. This behavior is what distinguishes a hub from other devices: switches forward frames to the specific port that leads to the destination MAC, routers use routing tables to direct traffic, and devices that convert digital to analog signals perform modulation/demodulation rather than data forwarding. Additionally, all devices on a hub share a single collision domain, which can lead to collisions in Ethernet networks. So the best description is that a hub forwards incoming data to all ports regardless of destination.
