CompTIA 901 Unit 2.9 Networking Tools

Which device sends an electrical signal through one pair of unshielded twisted pair (UTP) wires for the purpose of tracing it?

A tone generator

What device emits a beeping sound when it detects a signal in a pair of wires?

A tone probe

Which electrical instrument is used to determine if a signal is present on a network cable?

Cable tester

What is a Wi-Fi analyzer used for?

Detecting signal strength and points of interference

Which electronic instrument is used to measure voltage, current, and resistance?

Multimeter

In which situation would you use a cable stripper?

The remove only the outer coating of a cable and expose the inner wire

How are tone generators and tone probes different from cable testers?

They can only help you differentiate between different unshielded twisted pair (UTP) cables.

In what situation would you need to use a wire crimper?

To attach media connectors to the ends of cables

What type of device is inserted into a port and crosses over the transmit line to the receive line?

A loopback plug

When are you most likely to use a punch down tool?

When you need to connect cable wires directly to a patch panel
