How does a host on an Ethernet LAN know when to transmit after a collision has occurred? (Choose two.)

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.

You can improve the CSMA/CD network by adding more hubs.

After a collision, the station that detected the collision has first priority to resend the lost data.

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.

After a collision, all stations involved run an identical backoff algorithm and then synchronize with each other prior to transmitting data.
