To attach an RJ-45 connector to a Cat 6 UTP (Unshielded Twisted Pair) cable, a crimper is essential. This tool is specifically designed to securely attach connectors such as RJ-45 to the ends of the cable. The crimper works by pushing down tiny metal pins in the connector, which pierce through the insulation and make contact with the individual wires inside the cable, ensuring a solid connection for data transmission.

While a stripping tool is useful for preparing the cable by removing the outer jacket to expose the internal wires, it does not attach the connector itself. A soldering iron is not suited for use with RJ-45 connectors, as these connectors are typically crimped rather than soldered. Lastly, a multimeter is a testing tool used to check electrical connections, but it is not involved in the physical attachment of the connector to the cable. Therefore, the crimper is the specific tool required for this task.
