During a network installation, what should be monitored to avoid potential signal interference?

Monitoring the proximity of network cables to electrical wiring is crucial for avoiding potential signal interference. Electrical wiring carries current, which can generate electromagnetic fields that disrupt the data signals transmitted through network cables. When network cables are too close to these sources of electromagnetic interference (EMI), the integrity of the data can suffer, leading to degraded performance, increased error rates, and overall network instability.

Proper cable management typically adheres to industry standards that specify minimum distances between network cables and electrical wiring. By being vigilant about this aspect during the installation, one can ensure a more reliable network environment. Ignoring this element could result in poor network performance, impacting the effectiveness of network operations and communications.

The other choices do not relate directly to preventing interference. The layout of server racks pertains more to organization and airflow rather than signal integrity. The size of the cables may affect bandwidth capacity and attenuation but not directly signal interference from electrical sources. The age of networking equipment could influence performance but does not impact interference caused by nearby electrical wiring.
