NCTI 2023 Test: Field Tech II - III Conventional
Which of these components is used in a passive optical network (PON)?
Correct Ans - Optical splitters.
Which should be used to cut the fiberdrop's buffer tube? Correct Ans -
A tube cutter
What is one reason why broadband cable operators install fiber-optic cable in
stages instead of changing the infrastructure all at once? Correct Ans -
Changing the infrastructure all at once would cause too many service
disruptions.
When a pre-connectorized fiber is not attached to equipment, what should be
attached to help keep it clean? Correct Ans - A dust cap
Simplify and solve the equation: If E = IR then I = ? Correct Ans - E/R
(480 x 10 to the power of -5) divided by (60 x 10 to the power of -3) =
Correct Ans - 8 x 10 to the power of -2
7 3/8 divided by 7 1/4 = Correct Ans - 1 1/58
(20) / (-4) + (-2) x (-10) - (-2) x (7) = Correct Ans - 29
What should you avoid to prevent stress? Correct Ans - Excessive
caffeine
It is essential to pay attention to warning signs of stress overload. Poor
attitude is one of the behaviors that may indicate that you are overstressed.
What are the symptoms of poor attitude behavior? Correct Ans - A
significant change in attitude with a noticeable movement toward negative,
hostile, cynical, or paranoid thoughts
During which step of the six-step troubleshooting process for a digital TV
(DTV) service problem are quadrature amplitude modulation (QAM) channel
measurements typically taken? Correct Ans - Diagnosing symptoms.
, When troubleshooting a digital TV (DTV) authorization issue, what can be
verified using the set-top box (STB) diagnostic page? Correct Ans -
STB reception of authorization message data.
Which of the following is a multicast control protocol between the cable
modem and the CMTS that works in harmony with the downstream channel
bonding for efficient and extensible support for multicast applications?
Correct Ans - Source-specific multicast (SSM)
Which step in the troubleshooting process requires a discussion with the
customer to gather more detail about the problem? Correct Ans - Step
1: Identify the problem.
Which of the following wire color combinations make up quad station wire?
Correct Ans - Green, red, black, yellow
A customer reports a problem of no dial tone (NDT). Upon inspection, the
technician notices that new carpeting has been installed. What should the
technician do next? Correct Ans - Look for a cable that runs under the
carpet; it is likely that the cable has a short from the carpeting tack strip.
What uses the 2.4-GHz band and runs at 54 Mbps? Correct Ans -
802.11g
What is the last step of the basic wireless access point (WAP) setup?
Correct Ans - Apply security.
Why are wireless local area networks (WLAN) usually deployed in an access
capacity instead of as the network's core layer? Correct Ans - WLANs
are generally incapable of meeting the requirements of the network core
layer, which needs to be very fast and stable, able to handle a tremendous
amount of traffic with little difficulty, and must experience no down time.
Wireless internet service providers (ISP) provide which of one of the
following services? Correct Ans - Last mile data delivery
What is a symptom of a high voltage standing wave radio (VSWR) in a radio
transmitter? Correct Ans - high voltage standing wave radio
