CompTIA A+ 1101 Network Tools Flashcards
1
Q
- designed to add connectors to the end of a cable
- metal prongs are pushed through the insulation, and into the copper in the wire
A
Cable Crimpers
2
Q
- listens to all of the signals on a wireless network and provides you with information on what frequencies are in use, and which ones might be open
- especially useful in an area with many access points
- may be purpose-built hardware or a device add-on
A
WiFi Analyzer
3
Q
- traces wires
- connect to the end of the wire, and go to the other end, using the inductive probe to identify the wire, by the tone
A
Tone Generator
4
Q
- tests the interfaces of physical ports by connecting to the device
- typically is serial, using RS-232
- sends and receives information, then, compare the values to see if they match. (if they match, it’s very likely an interface problem)
A
Loopback Plugs
5
Q
- intercept network traffic and send a copy to a capture device
physical taps:
- used to see data on a connection (going over the wire)
- disconnect the link, put a tap in the middle, and take a copy of data to send to an analyzer, or a monitor
- can be passive or active (passive requires fiber, active can use copper, but requires power)
port mirrors:
- tapping functionality, built into switches
- software-based tap
- takes data that’s going in between different switch interfaces, and sends a copy of that data to a third interface that you can connect to an analyzer, or a monitor
A
Taps and Port Mirrors
