Live Virtual Machine Lab 5.3: Module 05 Physical Networking Tools

Which is a hardware device that is used for troubleshooting network transmission issues?

Loopback Adapter

Which tool uses red and black probes to measure voltage?

Multimeter

Which of the following devices is used to test a fiber cable to determine a fault and its length?

Optical Time-Domain Reflectometer (OTDR)

Which tool is used to connect a media connector to the end of a cable?

Cable Crimper

Which tool is used to test an Ethernet cable and creates a loopback connection?

Cable Tester A multimeter is used to measure voltage, current, and resistance. It has two probes, which are red and black. They are touched with the conductor to check the voltage, current, or resistance. A crimper, more properly known as a Klein modular plug crimper, or wire crimper, is a tool used to connect a media connector to the end of a cable. Wherever you have networking infrastructure, the patch panel or punchdown block is common. They have many wires embedded into the insulation-displacement connectors that they hold. The embedding of the wires into the connections is done by the punchdown tool, which can also be used for embedding cables into punchdown blocks, patch panels, keystone modules, and surface mount boxes. A loopback adapter is a hardware device that is used for troubleshooting network transmission issues. You need to connect the loopback adapter to a specific port from where it will send the transmission signals, which should be received at the other end of the port, something like a switch.
