1.On a half-duplex Ethernet LAN, two hosts attempt to send data simultaneously, resulting in a collision. Following this collision, what will the hosts do? (Select all valid answers)A. The destination host sends a request to the source for retransmission.B. The jam signal indicates that the collision has been cleared.C. The hosts will attempt to resume transmission after a time delay has expired.D. An electrical pulse indicates that the collision has cleared.E. The router on the segment will signal that the collision has cleared.F. The hosts will do nothing, as the higher layers are responsible for data error correction and re-transmission.

2.勾结（Collision）

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. 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.

4.Two stations on the Ezonexam LAN transmit at the same time, resulting in a collision. What happens when a collision occurs on the network? (Choose all that apply)A．Each device on the Ethernet segment stops transmitting for a short time.B．A jam signal informs all devices that a collision occurred.C．When data transmission resumes, the devices that were involved in the collision have priority to transmit.D．The devices that are involved in the collision stops transmitting for a short time.E．The collision invokes a random back-off algorithm.
