Which of the following cables provides maximum security against electronic eavesdropping on a
network?
A.
Fibre optic cable
B.
STP cable
C.
UTP cable
D.
NTP cable
Explanation:
A fibre optic cable provides maximum security against electronic eavesdropping on a
network. A fibre optic cable is an optical media. Signals
traveling in fibre optic cables are not electrical signals. Therefore, they do not emit electromagnetic
radiation and cannot be eavesdropped by
electromagnetic eavesdropping devices.
Answer options C and B are incorrect. In UTP and STP cables, the signals travel in electronic form
and emit electromagnetic radiation.
Therefore, these cables are not secure against electronic eavesdropping.
Answer option D is incorrect. There is no cable such as NTP.
