Question:
Although CSMA/CD is still a feature of Ethernet, why is it no longer necessary?

  • the virtually unlimited availability of IPv6 addresses
  • the use of CSMA/CA
  • the use of full-duplex capable Layer 2 switches
  • the development of half-duplex switch operation
  • the use of Gigabit Ethernet speeds

Explanation: The use of Layer 2 switches operating in full-duplex mode eliminates collisions, thereby eliminating the need for CSMA/CD.
