Which statement accurately describes what near end crosstalk (NEXT) is?
NEXT is crosstalk that occurs between wire pairs near the source of a signal.
NEXT is crosstalk that occurs near the opposite end of a signal source.
NEXT is crosstalk that occurs when an EMI source is near the data signal source.
NEXT is crosstalk that occurs only when a cable segment exceeds the bend radius
A junior administrator is having issues connecting to a router's console port using a TIA/EIA 568B standard cable and a USB serial to RJ-45 adapter, despite verifying terminal settings. What is the issue?
Router console ports are only used when connected to other routers.
The router console port is providing an Ethernet connection, instead of a serial connection.
The USB standard is incompatible with the serial connection used by the console port.
The cable must be a
rollover cable.
Noise that can degrade or distort a signal on a network is measured with what unit?
joules
volts
decibels
farads
What statement describes a transmission flaw that is occurring due to attenuation?
A customer modem is continuously losing signal due to large distance from the transmitting device.
A network switch interface is dropping due to a powerful radio transmitter in the adjacent room.
A customer's video conferencing application is experiencing delay in audio and video that comes and goes.
Two network interfaces are experiencing problems at the same time due to the cables having adjacent runs.
Utilizing time slots that are adjusted according to priority and need is an example of what type of multiplexing on copper lines?
time division multiplexing
statistical time division multiplexing
frequency division multiplexing
wavelength division multiplexing
In a coaxial cabling, what does the RG rating measure?
The number of twists in the copper core.
The overall thickness of the cable
The maximum distance the cable is rated for, in kilometers.
The materials used for shielding and conducting cores.
When terminating an Ethernet cable, about how far should the cable sheath extend into the plug?
1/2 inch
3/8 inch
4/5 inch
1/5 inch
What is the fastest Ethernet standard that can possibly be used on twisted-pair cabling?
100Base-T
1000Base-T
10GBase-T
10TBase-T
What kind of tool can you use to measure voltage on a cable length?
continuity tester
multimeter
time domain reflectometer
light meter
Why should you terminate coaxial cable with connectors that are rated for the exact cable type?
A mismatched connector will have different impedance ratings, causing data errors.
A mismatched connector will not fit the coaxial cable for termination.
A mismatched connector will work fine, but breaks cabling standards.
A mismatched connector will destroy the equipment it is connected to.
When viewing the pinout for T568B, what is the correct order of wire colors, starting at pin 1?
white/green, green, white/orange, blue, white/blue, orange, white/brown, brown
blue, white/blue, green, white/green, orange, white/orange, brown, white/brown
white/orange, orange, white/green, blue, white/blue, green, white/brown, brown
white/brown, brown, white/green, blue, white/blue, green, orange, white/orange
What statement regarding the Power Over Ethernet standards is inaccurate?
The amount of power provided is 15.4 watts for standard PoE devices.
Power over Ethernet requires CAT6 or better copper cable
Electric current may run over a pair of wires used for data transmission
A device that supplies power for PoE is known as power sourcing equipment.
What statement correctly describes "jitter"?
Jitter is what happens when packets experience varying amounts of delay and arrive out of order.
Jitter is the loss of 50% or more packets in a given data stream, causing a connection to falter
Jitter is the fluctuation of a signal's strength as it travels away from its source
Jitter is the transmission of signal onto unintended pairs in a copper cable
