Question

question 14 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 development of half - duplex switch operation the use of full - duplex capable layer 2 switches the use of gigabit ethernet speeds

Explanation:

CSMA/CD (Carrier - Sense Multiple Access with Collision Detection) was used to handle collisions in half - duplex Ethernet. Full - duplex capable Layer 2 switches allow simultaneous sending and receiving of data on a link without collisions. So, CSMA/CD is no longer necessary as there are no collisions to detect in full - duplex mode.

Answer:

The use of full - duplex capable Layer 2 switches
