Question

A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment. Which two factors may interfere with the copper cabling and result in signal distortion and data corruption? (Choose two.)EMIcrosstalkRFIsignal attenuationextended length of cabling

Answer 1

Answer: EMI(Electromagnetic interference)

               RFI(Radio frequency interference)

Explanation: Electromagnetic interference is the emission of the electromagnetic signal that can disturb the working of the other device.It invokes the disturbance that can create error, under-performance mechanism,distortion etc in the equipment.

Radio-frequency interference(RFI) is the radio-frequency signal that interferes the other device by creating noise and distortion. This leads to breaking of the operation and data error.

Other options are incorrect because cross talk is referred as undesired communication between signal ,attenuation is the degradation in the  amplitude of any signal and extended length of cabling is increasing the length of the cable.Thus the correct answer is RFI and EMI.
