Network Fundamentals

A device detects two stations transmitting frames at the same time. This condition occurs after the first 64 bytes of the frame are received. Which interface counter increases?

  • A runt
  • B collision
  • C late collision
  • D CRC
Explanation

A collision that is detected after the first 64 bytes of an Ethernet frame is a late collision. Standard Ethernet collisions are expected to occur within the initial 64-byte collision window; when the collision is detected after that point, the interface records it as a late-collision event rather than a normal collision, runt, or CRC error.
