A network administrator notices increased complaints about slow network speeds in a particular office section. Upon inspection, the administrator observes that the Ethernet cables running to this section are bundled tightly with power cables along significant lengths. What is the most likely cause of the reported network performance issues?
High cable temperatures reducing transmission efficiency
The correct answer is 'Electromagnetic interference from power cables'. Electromagnetic interference (EMI) can cause signal degradation when data cables are run in close proximity to power cables without adequate shielding. This can lead to errors and slow network speeds due to the need for data retransmission. Other possible issues such as signal blocking by walls or signal absorption by materials do not typically apply to Ethernet cables, as these are more relevant to wireless networks.
