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.
