During an inspection of a newly installed office network, an IT technician notes that network performance deteriorates significantly during peak operational hours. The technician observes that Ethernet cables are laid parallel and close to multiple electrical conduits and fluorescent lighting fixtures throughout the facility. Which issue is MOST likely contributing to the network performance degradation?
Electromagnetic interference from nearby electrical conduits and lighting fixtures
Inadequate shielding of Ethernet cables exacerbating signal attenuation
Suboptimal cable category unable to handle high bandwidth demand
Degradation due to overextended cable lengths beyond specified limits
