Why each option

A punchdown tool is the correct instrument for terminating individual twisted-pair wires into keystone wall jacks and patch panels.

APunchdownCorrect

A punchdown tool (also called an impact tool) seats individual wire conductors into the insulation displacement contacts (IDC) of a keystone jack or patch panel, simultaneously trimming the excess wire. This is the standard and only appropriate tool for this specific type of network cable termination at a wall jack.

BLoopback plug

A loopback plug is a diagnostic tool used to test network port functionality; it cannot terminate or connect cables.

CMultimeter

A multimeter measures electrical properties such as voltage, resistance, and continuity; it is not used to physically connect cables.

DCrimper

A crimper is used to attach RJ-45 or RJ-11 connectors to the end of a cable, not to terminate wires into a wall jack.
