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?

I feel like B is the strongest option. Fix the cable, fix the problem!

D) a cable that is too long could also be a factor, but less likely.

But the FCS-Err points more to a physical issue. B makes sense.

I lean towards C) a speed mismatch. Could be settings off on devices.

Agreed! A faulty cable can cause unreliable data transfers.

I think it's B) a physical cable fault. High FCS-Err suggests issues there.

Yeah, I agree, it's probably the cable.

Wait, could it really be a cable fault? That seems odd.

Definitely a cable issue, high FCS-Err is a red flag!

I recall something about cable length affecting performance, but I don't think that's the main issue here with the FCS errors.

I practiced a question similar to this, and I think high bandwidth usage was ruled out because latency was minimal.

I’m not entirely sure, but I feel like a speed mismatch could also cause unreliable data transfers.

I remember studying about FCS errors, and I think they usually indicate a physical layer issue, so maybe it's a cable fault?
