3.Which two statements describe the operation of the CSMA/CD access method, which is in use on the Ezonexam network? (Choose two)A. After a collision, the station that detected the collision has first priority to resend the lost data.B. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.C. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.D.
