Hardware Tools Flashcards
Which is the most widely used hardware tool in today’s LANs?
Cable testers
What type of tester achieves the below?
1) if cable is straight through or crossover
2) grounding issues
3) Causes of slow performance
Cable tester
when choosing testing equipment, you should choose them based on the test results required by the standards you’re using to certify the network - TRUE or FALSE?
TRUE
Which copper hardware tester can determine if the wires are going to the right pins?
wire-map tester
What type of issue do wire-map testers not detect and what type of test would detect it?
Split pairs. Near-end cross talk test should detect split pairs
cable testers can tell if a cable can pass ethernet data at network speeds. TRUE or FALSE?
FALSE, it can only test for simple things like opens, shorts and crossed pairs
What hardware/software device can perform the following:
- help detect malware
- provide a traffic generator for pen testing
- help you learn about networking in general
Protocol analyzer
Certification testers are used to determine whether your network meets what?
whether your network meets specific ISO or TIA standards Cat5e to 7.
What hardware device tests the following:
- speed and condition of cable
- how long it takes to send a signal down a cable and back again
- cable impedance
- splice connector locations
- estimated cable length
A time-domain reflector
What type of optical tester can give you the below information?
1) fibre’s length
2) overall attenuation
3) location of faults
OTDR
What device would you use to measure the strength of radio signals present in the area to locate interference?
Spectrum analyzer
What type of test helps you find which wall-plate terminates on which connector on a punchdown block?
Toner probe (or wiremap tester)
Which device is more practical and saves time to use instead of a toner probe?
wire-map tester
What are two important benefits of baselining and recording metrics over time using hardware testing tools?
1) to see if a problem has gotten better or worse
2) to determine if interventions you’ve taken to improve a scenario have worked
what is a key metric for network baselining using hardware tools?
Error rate
What tool is used to test wet or dry lines?
a butt set
What is a hound and what other hardware device is it typically used with?
it’s a small speaker used to monitor the audio or noise on a line. It’s used with a toner probe.
what are wires ‘punched down’ onto?
Insulating Displacement Connectors
What voltage and type current rings a phone line?
140V AC
What device would you use in the following scenarios?
1) Recording Voltage
2) Measuring Distortion
3) Measuring Flicker
4) Capturing voltage transients
Voltage Event Recorder
What can high humidity and low humidity cause?
High humidity can cause corrosion of electrical parts
Low humidity can cause a build up of static electricity
What do you base you choice of temperature and humidity monitor on?
1) size of room
2) how many devices you have in it
you’re having issues with performance across several servers. You’ve tested bandwidth and power, what else could be the problem?
temperature
