FC0-U61 · Question #327

Which of the following can occur if the power cable runs along with the computer network cable?

The correct answer is A. EMI. Running a power cable parallel to a network cable can induce electromagnetic interference (EMI), degrading the network signal quality and potentially causing data errors or connection issues.

Why each option

Running a power cable parallel to a network cable can induce electromagnetic interference (EMI), degrading the network signal quality and potentially causing data errors or connection issues.

AEMICorrect

Electromagnetic Interference (EMI) can occur when power cables are run in close proximity to data cables, as the fluctuating current in the power cable can induce unwanted electrical noise into the network cable, disrupting data transmission.

BESD

ESD (Electrostatic Discharge) is the sudden flow of electricity between two electrically charged objects caused by contact, an event related to static electricity, not proximity of power and network cables.

CBroadcast storm

A broadcast storm is a network phenomenon caused by an excessive amount of broadcast traffic, overwhelming network devices and consuming bandwidth, which is a software or configuration issue, not a cabling issue.

DSurge

A surge is a transient wave of current or voltage, typically associated with power fluctuations or lightning strikes, which affects the power supply directly and is not caused by the mere proximity of power and network cables.
