each job location? - Correct Answer: Notes and recorded data are tools
that can help you accurately remember events at a site that can help you
determine a plan of action or evaluate the decisions you made.
10.You are at a customer's home and you believe you have solved the problem.
When you check to be sure the resolution did not introduce any new

process? - Correct Answer: Verifying the solution.
11.To break the habit of a negative self-talk cycle - Correct Answer: Tell
yourself "not now" and move onto a positive thought whenever negative
thoughts occur.
,12.By taking control of the expectations you have, you are - Correct
Answer: More likely to improve your motivation and be a better problem
solver.
13.Which of the following characterizes the successful troubleshooter? -
Correct Answer: Someone with an inquisitive and relentless desire to solve
and fix problems.
14.What must a technician be aware of when analyzing a digital TV (DTV)
problem? - Correct Answer: There is frequently more than one
contributor to a specific DTV service problem.
15.After a digital TV (DTV) service problem has been analyzed and possible
causes considered, what is accomplished by isolating the various network
elements? - Correct Answer: It narrows the scope of likely problem
sources.
16.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 Answer: Diagnosing
symptoms.
17.When replacing a splitter to resolve a digital TV (DTV) service problem, what
does confirming the splitter output levels before attaching the output
connectors do? - Correct Answer: Confirmation reinforces the
technician's confidence that the problem will be resolved by replacing the

same frequencies used for cable modems? - Correct Answer: STB with
DOCSIS Set-top Gateway (DSG) client software and embedded DOCSIS
modems.
21.Because the spectral density of a quadrature amplitude modulation (QAM)
channel is much higher than that of an analog TV channel, what is done to
ensure equal power in all channels in a network with analog and digital
modulation channels? - Correct Answer: Operate the analog TV
channels at higher amplitude level than the QAM channels.
22.What does a set-top box (STB) diagnostic page of a quadrature amplitude
modulation (QAM) channel showing signal-to-noise ratio (SNR) near or
below 30 dB indicate? - Correct Answer: The QAM channel quality is on
the edge for reliable reception, and the source of the problem is likely in the
distribution network or customer premises.
