Correct Answer. C. Shielding type When running network cables alongside power lines, it is crucial to use cables with adequate shielding, such as STP cables, to protect against EMI from the power lines. Shielding helps prevent data loss and errors by blocking unwanted interference.
Option A is incorrect because while cable length can impact signal strength, shielding is more crucial for protecting against interference when cables are near power lines.
Option B is incorrect because the color of the cable has no effect on its performance or ability to resist interference.
Option D is incorrect because although cable flexibility may be important for the physical routing of cables, it does not affect the cable's ability to resist electromagnetic interference.
