Troubleshooting Theory: 1 2 3 4 5 6.
True or False: Use a cable tester to test for frequency and cross talk, and signal loss. True False.
Useful hardware tool for testing the integrity of fiber optic cables. It can verify splice loss, measure length and find faults.
Some Hardware Tools: Light Meter OTDR Cable Tester Punchdown tool Crimper Tone Generator.
What is pictured?.
What hardware tool can be used to check for continuity? Check all that apply. Multimeter Cable tester Loopback plug OTDR Crimper.
What hardware tool checks all of the frequencies in a range all at once. Spectrum Analyzer OTDR Cable Tester Tone Generator.
Software tool that shows frame by frame breakdown of a packet: Protocol analyzer Port scanner Packet sniffer Spectrum analyzer.
You want to look for all open ports on a range of IP addresses. What software tool can you use?.
What would you use to detect rogue systems attached to a network? Port Scanner Spectrum Analyzer Packet Sniffer Protocol analyzer.
What is the gradual signal loss over a wired communication called? Attenuation Emulation Loopback Latency.
A delay between the request and the response...this is known as: Latency Attenuation Ping time Jitter.
Which of these problems would be related to real-time media delays? Jitter Attenuation Latency Crosstalk.
The signal on one pair of wires is affecting the signal on another pair of wires:.
Excessive crosstalk is almost always a result of ______. bad wiring jitter problems inconsistent power electromagnetic interference.
The most useful tool in checking for electromagnetic interference and signal problems is: TDR Multimeter Signal surveryer Packet analyzer.
2 wires touching each other will cause: Short circuit EMI Attenuation Crosstalk.
If there is a mismatch between duplex on a wired connection, what would happen? Speed slowdowns and collisions Termination of the connection Nothing, it will adjust to correct duplex automatically DHCP will go down.
In wireless networks, you may have a problem with __________ which is where signals bounce. Attenuation Reflection Jitter Refraction.
Which of the following wireless standards might a little reflection actually help? 802.11g 802.11a 802.11ac 802.11n.
In an outdoor, long distance wireless link where there are changes in temperature and there is water vapor present - you could have a problem with: Refraction Reflection EMI Absorption.
Opposite of reflection would be ____.
Which of the following would help with attenuation on your wireless home network? Turn up signal strength of the WAP Change the SSID Use omnidirectional antennae Keep away from other electronic devices.
Which command line command could you use to view ethernet statistics?.
What type of antennae would be best for connecting 2 buildings together on a wireless connection?.
What type of antennae is best to mount on the ceiling for best wireless access coverage?.
Which has more non-overlapping channels? 2.4 Ghz wireless 5 Ghz wireless.
