Which of the following is an advantage of fiber-optic over copper cables from a security perspective?

A.
Fiber optics provides higher bandwidth.

B.
Fiber optics are more difficult to wiretap.

C.
Fiber optics are immune to wiretap.

D.
None�the two are equivalent; network security is independent from the physical layer.

Explanation:
B: From a security perspective, fiber optics immunity to electromagnetic interference (EMI) and radio frequency interference (RFI) is important. Because fiber optics emit extremely small amounts of energy from the cable, data cannot be as easily intercepted as information is transported through electric current in wires. Page 762.
