What are three characteristics of the CSMA/CD process? (Choose three.)
- The device with the electronic token is the only one that can transmit after a collision.
- A device listens and waits until the media is not busy before transmitting.
- After detecting a collision, hosts can attempt to resume transmission after a random time delay has expired.
- All of the devices on a segment see data that passes on the network medium.
- A jam signal indicates that the collision has cleared and the media is not busy.
- Devices can be configured with a higher transmission priority.
Explanation: The Carrier Sense Multiple Access/Collision Detection (CSMA/CD) process is a contention-based media access control mechanism used on shared media access networks, such as Ethernet. When a device needs to transmit data, it listens and waits until the media is available (quiet), then it will send data. If two devices transmit at the same time, a collision will occur. Both devices will detect the collision on the network. When a device detects a collision, it will stop the data transmission process, wait for a random amount of time, then try again.
