In a very secure facility, you are installing network cabling. The cables must be resistant to electronic eavesdropping. What kind of cable should you use?

A Fiber-optic.

Fiber-optic cable transmits data using light pulses rather than electric voltages, making it resistant to electrical interference and wiretapping. Copper cables, such as UTP, STP, and coaxial, require electricity to carry data and can thus be exposed to electronic eavesdropping.
