Multiple choice

Refer to the exhibit. The switch and workstation are administratively configured for full-duplex operation. Which of the following statements accurately reflects the operation of this link?

  1. No collisions will occur on this link.

  2. Only one of the devices can transmit at a time.

  3. The switch will have priority for transmitting data.

  4. The devices will default back to half duplex if excessive collisions occur.

A Correct answer
Explanation

Full-duplex Ethernet allows simultaneous transmission and reception on both ends of the link. In full-duplex mode, collisions are physically impossible because each device has separate transmit and receive circuits. The switch and workstation can both send and receive at the same time without contention. Half-duplex uses CSMA/CD to detect collisions, but full-duplex disables this mechanism entirely.
