Why each option
Replacing a CAT5e wall jack requires a punch down tool to terminate the wires and a cable tester to validate the installation is correct.
A cable crimper is used to attach RJ45 connectors to the end of patch cables, not to terminate wires inside a wall jack.
A loopback plug tests a NIC's ability to send and receive data and is not involved in installing or validating a wall jack.
A voltage meter measures electrical voltage in circuits and has no function in installing or testing a network cable jack.
A cable tester is used after installation to verify that all wire pairs are correctly terminated and that the jack passes continuity and wiring checks, validating the hardware is functional.
A punch down tool is required to seat each individual wire into the 110-type IDC contacts on the keystone jack, which is the standard termination method for wall jacks.
