CISSP · Question #34
Which one of the following transmission media is MOST effective in preventing data interception?
The correct answer is C. Fiber optic. Fiber optic is the most effective transmission media in preventing data interception, as it uses light signals to transmit data over thin glass or plastic fibers. Fiber optic cables are immune to electromagnetic interference, which means that they cannot be tapped or eavesdropped

Explanation
Fiber optic is the most effective transmission media in preventing data interception, as it uses light signals to transmit data over thin glass or plastic fibers. Fiber optic cables are immune to electromagnetic interference, which means that they cannot be tapped or eavesdropped by external devices or signals. Fiber optic cables also have a low attenuation rate, which means that they can transmit data over long distances without losing much signal strength or quality. Microwave, twisted-pair, and coaxial cable are less effective transmission media in preventing data interception, as they use electromagnetic waves or electrical signals to transmit data over metal wires or air. These media are susceptible to interference, noise, or tapping, which can compromise the confidentiality or integrity of the data.
