(Choose 2)

In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously
In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
The use of hubs to enlarge the size of collisions domains is one way to improve the operation of the CSMA/CD access method
After a collision, the station that detected the collision has first priority to resend the lost data
After a collision, all stations involved run an identical back off algorithm and then synchronize with each other prior to transmitting data.
