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. The use of hubs to enlarge the size of collision domains is one way to improve the operation of the CSMA/CD access method.E. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.F. After a collision, all stations involved run an identical backoff algorithm and then synchronize with each other prior to transmitting data.
