Interference
Answers
B.
Interference
C.
Decibel loss
Answers
C.
Decibel loss
D.
Incorrect pinout
Answers
D.
Incorrect pinout
Suggested answer: A

Explanation:

Attenuation is the loss of signal strength as it travels over a distance or through a medium. It ismeasured in decibels (dB) and can affect the quality and reliability of network communication.In this scenario, the connection from PC A to switch 1 is using a Cat 5 cable with a length of394ft (120m), which exceeds the recommended maximum length of 328ft (100m) for twisted-pair cables. This can cause significant attenuation and performance degradation between PC Aand PC B.To solve this problem, the network technician should either reduce the cable length, use ahigher category cable, or insert a repeater or amplifier device to boost the signal strength.Interference is the unwanted noise or signal that affects the network communication. It can becaused by electromagnetic sources, such as power lines, motors, or wireless devices, or bycrosstalk, which is the interference between adjacent wires in a cable. Interference can alsoaffect the network performance, but it is not the most likely cause in this scenario, as it wouldaffect all the connections, not just the one with the excessive cable length.Decibel loss is another term for attenuation, so it is not a separate option. Incorrect pinout isthe wrong arrangement of wires in a cable connector, which can prevent the network devicesfrom communicating properly. However, this is not the most likely cause in this scenario, as thecable configuration is correct (straight through) for the connection from PC A to switch
