Report
Export

A customer is having issues accessing local resources on the network. A technician questions the user and discovers that a small switch had been taken out of storage and installed so that additional devices could be connected in the room. The technician runs the ping command from the PC to the network server and does not find any issues. However, data transfers to the server are slow, and the transfer appears to be locked up at times. Which of the following is the most likely cause of the issue?

A.
Duplexing mismatch

B.
Reversed TX/RX pinouts

Cable crosstalk
Answers
C.
Cable crosstalk
D.
Failed transceiver
Answers
D.
Failed transceiver
Suggested answer: A

Explanation:

A duplex mismatch is the most probable cause of the issues described, where the network connection experiences slow data transfers and intermittent lockups. This occurs when one device in a network connection operates in full-duplex mode and the other in half-duplex, leading to collisions and performance issues. In the scenario provided, the small switch taken from storage may not have been configured to match the duplex settings of the existing network, resulting in these data transfer issues. Other options like reversed TX/RX pinouts, cable crosstalk, or a failed transceiver would typically result in complete connection failures or consistent degradation, not intermittent issues as described.
