New Questions 12

In Ethernet networks, duplex mismatches will lower performance. Which error statistics can be seen if a duplex mismatch is present?

A. collisions on the full-duplex side; runts on the half-duplex side

B. collisions on the full-duplex side; collisions on the half-duplex side

C. collisions on the half-duplex side; framing errors on the full-duplex side

D. collisions on the half-duplex side; giants on the full-duplex side

Answer: C


On an Ethernet connection, a duplex mismatch is a condition where two connected devices operate in different duplex modes, that is, one operates in half duplex while the other one operates in full duplex.

This results in the full-duplex side receiving an incomplete frame with CRC error or a runt frame. It does not detect any collision since CSMA/CD is disabled on the full-duplex side. As a result, when both devices are attempting to transmit at (nearly) the same time, the packet sent by the full-duplex end will be discarded and lost due to an assumed collision and the packet sent by the half duplex device will be delayed or lost due to a CRC error in the frame.
