Which of the following is a common risk with fiber optical communications, and what is the associated mitigation measure?

Data emanation is an electromagnetic emission risk associated with copper cabling, not fiber optics, and CAT 6 cable is a copper-based solution unrelated to fiber optic security.

Fiber optic communications are susceptible to light leakage, where light signals escape through imperfections, tight bends, or poorly made splices in the cable. This leaked light can potentially be intercepted by an attacker using specialized equipment. Deploying shielded (armored or specially jacketed) fiber optic cable helps contain the light within the cable and prevents signal interception through physical tapping or leakage.

While cable damage is a concern for any cabling, ring architecture is a network topology design choice for redundancy and availability, not a direct mitigation for fiber optic communication risks.

Electronic eavesdropping applies primarily to copper or wireless communications that emit electromagnetic signals; fiber optics do not produce electrical signals that can be electronically intercepted in the traditional sense.
