Lucinda is a network manager. She wants to set up a small office computer network so that it will not be affected at all by electrical or electromagnetic Interference. Which network media should she use?
ОА.
twisted-pair
OB.
coaxial
O C.
fiber optic
OD
wireless
E.
shielded twisted-pair

The network media she should use is;

E. Shielded twisted-pair

Explanation:

A network connection that will not be affected by electrical or electromagnetic interference is a shielded twisted pair cable

Electromagnetic interference, EMI, is an externally originating disturbance that has an impact on electrical circuits through electromagnetic induction, direct conduction, or electrostatic coupling, with the possible effect of circuit degradation or disruption

EMI can be prevented by the use of shielded twisted pair (STP) cabling that provides a barrier that reduces the effect of external electromagnetic fields and transports the current induced to the ground through a grounding wire
