VTY

What are three characteristics of CSMA/CD? (Choose three.)

Devices listen to the media and transmit data only when they cannot detect another signal on the media.

All devices on the media can hear all communications.

Devices communicate based on a configured priority.

After a collision occurs, the devices that caused the collision have first priority when attempting to retransmit.

When a collision occurs, all devices stop transmitting for a randomly generated period of time.

CSMA/CD uses a token system to avoid collisions.

Refer to the exhibit. A PC is connected to a network. Which action will verify that the PC can communicate with its default gateway?
