A technician is investigating intermittent switch degradation. The issue only seems to occur when the buildings roof air conditioning system runs. Which of the following would reduce the…

A heat deflector redirects airflow to manage temperature around equipment; it does not address electromagnetic interference from the AC motor and would not resolve signal degradation caused by EMI.

Redundant HVAC systems would ensure cooling continuity but would actually increase the EMI problem by having additional motors running; they do not eliminate the electromagnetic interference affecting the switch.

Large electrical motors in air conditioning systems generate significant electromagnetic interference (EMI) that can induce noise on nearby unshielded network cables, causing packet errors, collisions, and degraded switch performance. Installing shielded twisted pair (STP) cables or placing EMI shielding around the affected network equipment physically blocks the interfering electromagnetic fields, directly addressing the root cause of the intermittent degradation that correlates with AC operation.

Adding a wireless network would introduce a different transmission medium but would not fix the wired switch degradation and would itself be susceptible to interference from the same AC system in the 2.4 GHz or 5 GHz frequency ranges.
