Which factor can lead to data transmission errors in a network?

Crossed pairs can lead to data transmission errors in a network because they disrupt the intended signal path within twisted-pair cabling. Twisted-pair cables are designed with pairs of wires that are twisted together to minimize electromagnetic interference and maintain the integrity of the data signal. When the pairs are crossed, it can cause crosstalk, which is the unwanted transfer of signals between the wires. This interference can degrade the quality of the data being transmitted, leading to errors such as data corruption or loss of communication.

In contrast, signal amplification is typically used to boost weak signals over long cable runs and should not inherently cause transmission errors if done correctly. Proper termination ensures that the signals are correctly connected to the network, which maintains the signal quality. Short cable runs generally reduce the chances of errors because they minimize the potential for interference and signal degradation. Thus, while cross-pairing disrupts the integrity of the transmission, the other factors listed typically support effective data transmission when properly implemented.
