A client experiences slow throughput from a server that is directly (CCNA 200-301)
A client experiences slow throughput from a server that is directly connected to the core switch in a data center. A network engineer finds minimal latency on connections to the server, but data transfers are unreliable, and the output of the show interfaces counters errors command shows a high FCS-Err count on the interface that is connected to the server.
What is the cause of the throughput issue?
A. a physical cable fault
B. a speed mismatch
C. high bandwidth usage
D. a cable that is too long
Solution
Correct answer: A. a physical cable fault.
The cause of the throughput issue is likely a physical cable fault (A). The high FCS-Err (Frame Check Sequence Error) count on the interface indicates that the switch is receiving frames with errors, which can be caused by a faulty or damaged cable. This would explain the unreliable data transfers and slow throughput, despite minimal latency.
