2.8 Given a scenario, use appropriate networking tools.

Used only on coax cable installations connecting two cables terminated with BNCs

BNC (Barrel Nut Connector) coupler

It can be used to diagnose Ethernet wiring problems from broken/cut cables, loose wires to crossed pairs.

Cable tester

The cable TV is not working in the Director's office. It does seem to be working in other offices. You have verified that the coax cables are all connected. Which tool will you now need to see if there are any issues with the cable?

Multimeter

You have been given a support ticket to test a cable that does not seem to be working correctly. Using one of your hardware tools to troubleshoot connectivity issues, you get a reading of infinity. What tool did you use and what does the reading tell you about the cable?

Multimeter, the cable has a break

You have been tasked with making some cable runs to accommodate new offices. After running the cable, you now need to attach the cable to the back of the patch panel. What tool will you need to complete this task?

Punch-down tool

There is a network (RJ45) port in the Director's office, but recently it stopped working. There is no connectivity provided when plugged into the port. The cable and the workstation's Network Interface Card (NIC) are verified good. You need to make sure the cable on the back-end of the port is connected but the cables in the wiring closet are not labeled. Which tool can you use to perform this task?

Tone generator/probe

A device that can monitor your wireless network environment and help identify potential issues

WiFi analyzer

A user is complaining of having very weak wireless signal. What device would you use to check the signal strength from the user's location?

WiFi analyzer

This tool can be used to fix a jack to a cable

cable crimper

New offices have been built for additional staffing. You need to install cables in each of these offices. After running the cables, what tool will you need to use to prepare the cables before installing the connectors?

cable stripper

What tool would you use when you need to remove the protective coating of a cable and expose the wire inside of it?

cable stripper

What are the most necessary tools to successfully make a new cable?

cable stripper and crimper

This tool will help you identify the cable condition, any crosstalk, loss of attenuation noise, resistance, and any other characteristics that may be adversely affecting the cable connection.

cable tester

You receive a trouble ticket from a user that the network seems to be running slow. You have verified the device side and found no problems and the Ethernet cable is properly connected. What tool would you use next to test the connection?

cable tester

A technician needs to attach an RJ-45 connector to a Cat 5e Ethernet cable, what tool would the technician use?

crimper

A tool that is useful when you need to attach media connectors to the end of a cable.

crimper

A WiFi analyzer shows signal strength measured in this expressed in a negative value

dGm (decibel-milliwatts)

A device used to test ports (such as serial, parallel USB and network ports) to identify network and network interface card (NIC) issues

loopback plug

A tool that causes a device to transmit a signal back to itself

loopback plug

The Engineering department has been relocated to new offices. You are responsible for moving RJ-45 wall jacks to new locations in these offices. Which tool can you use to verify these RJ-45 port connections after each has been moved?

loopback plug

Which device is most commonly used for diagnosing transmission problems on Ethernet cables

loopback plug

This device combines many electrical meters as a single unite which can measure current, resistance and voltage

multimeter

This device is used to check shorts in a coax cable

multimeter

A computer network admin software utility used to test connectivity.

ping

A hand tool used to connect telecommunications and network wires to a patch panel

punch-down tool

The IT department is revamping the wiring closet to improve cable management. A new patch panel has been installed on the rack in the room and you have been tasked with terminating the cables into the patch panel. Which tool would you need to use to complete your task?

punch-down tool

This tool works by stripping the insulation from the end of the wire and embedding the wire into the connection at the back of the panel.

punch-down tool

Which device uses time-domain reflectometry to characterize and locate faults in metallic cables?

reflectometer

-25 dBM is a stronger or weaker signal than -90 dBm?

stronger

Which tools allow you to differentiate between different unshielded twisted pair (UTP) cables, and do not confirm that a signal is actually present?

tone generator/probe

You can use this tool to trace and follow a cable end to end

tone generator/probe
