Explanation & Hint:

The purpose of a repeater, like the one found by the technician, is to regenerate weak signals to extend the distance a signal can travel. A repeater is a network device used to extend the reach of a network signal. It works by receiving a weak or low-level signal, amplifying it, and then transmitting the boosted signal further. Repeaters are used in both wired and wireless networks to ensure that the signal can cover longer distances without degradation.

The other options describe different network devices or functionalities:
