Multiple choice

Refer to the exhibit. Hosts B and C attempt to transmit a frame at the same time, but a collision occurs. Which hosts will receive the collision jamming signal?

  1. All hosts that are shown

  2. Only hosts B and C

  3. Only hosts A, B, and C

  4. Only hosts A, B, C, and D

  5. Only hosts A, D, E, and F

C Correct answer
Explanation

In Ethernet, when a collision occurs on a shared medium (like a hub), the jamming signal propagates throughout the collision domain. All hosts connected to the same physical segment receive and process this jam signal, which causes all transmitting stations to stop and back off using the exponential backoff algorithm. The exhibit shows hosts A, B, and C connected to the same collision domain (likely a shared hub), while D, E, and F are separated by a switch, bridge, or router boundary. Only hosts on the same collision domain receive the jamming signal.
