In Ethernet's CSMA/CD with binary exponential backoff, after the third collision of the same frame a station waits for K slot times, where K is chosen at random from

  • A0 to 3
  • B0 to 15
  • C0 to 7
  • D0 to 2
Correct answer: C

Explanation

After the n-th collision K is chosen at random from 0 to 2ⁿ − 1, so after the third collision the range is 0 to 7, and the range doubles with every further collision up to a limit.
