In a 10 Mbps CSMA/CD Ethernet the round-trip propagation delay is 51.2 µs. The minimum frame size needed to detect every collision is

  • A32 bytes
  • B512 bytes
  • C128 bytes
  • D64 bytes
Correct answer: D

Explanation

The frame must last at least one round trip: 10 Mbps × 51.2 µs = 512 bits = 64 bytes.
