The correct answer is A. Crimper. A crimper is the hand tool used to press the RJ-45 connector's pins onto the cable conductors, securing a new termination.
Question

- ACrimper
- BCable certifier
- CLoopback plug
- DPunch down tool

Why each option
A crimper is the hand tool used to press the RJ-45 connector's pins onto the cable conductors, securing a new termination.
A crimping tool mechanically deforms the RJ-45 connector's metal contacts, forcing them to pierce and grip the individual copper conductors. This is the correct tool whenever a patch cable needs a new connector attached, including situations where the jacket was stripped back too far causing excessive untwisting and crosstalk.
A cable certifier tests the finished cable against TIA/EIA standards for attenuation, crosstalk, and other parameters; it does not attach connectors.
A loopback plug is used to test a port or NIC by redirecting its output back to its input; it has no role in connector installation.
A punch down tool terminates conductors into 110-block patch panels or keystone jacks, not into RJ-45 field-termination connectors.
