indicate that you are overstressed. What are the symptoms of
poor attitude behavior? - ✔✔A significant change in attitude with a noticeable movement
toward negative, hostile, cynical, or paranoid thoughts
✔✔You are at a customer's home, and you believe you have
solved the problem. When you check to ensure the resolution
did not introduce any new problems, which step are you using
from the six-step troubleshooting process? - ✔✔Verify the solution
✔✔To break the habit of a negative self-talk cycle - ✔✔Tell yourself "not now" and move
onto a positive thought whenever negative thoughts occur.
✔✔By taking control of the expectations you have, you are - ✔✔More likely to improve
your motivation and be a better problem solver.
✔✔Which of the following statements describes creative
problem-solving? - ✔✔Thinking outside of the box and looking at problems from a fresh
perspective.
✔✔What is done to ensure equal power in all
channels in a network with analog and digital
modulation channels? - ✔✔Operate the analog TV channels at higher amplitude level
than the QAM channels
✔✔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? - ✔✔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.
✔✔Which of the following characterizes the successful
troubleshooter? - ✔✔Someone with an inquisitive and relentless desire to solve and fix
problems.
✔✔What must a technician be aware of when analyzing a digital TV (DTV) problem? -
✔✔There is frequently more than one contributor to a specific DTV service problem.
, ✔✔After a digital TV (DTV) service problem has been analyzed and possible causes
considered, what is accomplished by isolating the various network elements? - ✔✔It
narrows the scope of likely problem sources.
✔✔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? - ✔✔Diagnosing symptoms.
✔✔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? - ✔✔Confirmation reinforces the technician's
confidence that the problem will be resolved by replacing the splitter.
✔✔Which of the following digital TV (DTV) trouble calls could
have been avoided with customer education about the
product? - ✔✔The digital set-top box (STB) overheats.
✔✔When troubleshooting a digital TV (DTV) authorization issue,
what can be verified using the set-top box (STB) diagnostic
page? - ✔✔STB reception of authorization message data.
✔✔Which type of set-top box (STB) operates more like Data Over Cable Service
Interface Specification (DOCSIS) cable modems with return channels on the same
frequencies used for cable modems? - ✔✔STB with DOCSIS Set-top Gateway (DSG)
client software and embedded DOCSIS modems.
✔✔How does IP multicast differ from IP broadcast? - ✔✔IP multicast traffic is only sent
to specific modem addresses on the network; IP broadcast traffic is sent to all modems
on the network.
✔✔What layers of the OSI reference model are
specific to cable networks and are present
onlv between DOCSIS modems and the
CMTS? - ✔✔Layers 1 through 4 (Physical layer, Data Link Layer, Network Layer, and
Transport Laver) are
applied between the DOCSIS modem and CMTS.
✔✔Which DOCSIS layer is used by the CMTS to differentiate
between cable modems? - ✔✔The Docsis MAC layer
✔✔What was introduced in DOCSIS 3.0 to allow enough
bandwidth for upstream carriers from previous DOCSIS
versions? - ✔✔The option to increase the top frequency of the upstream to 85
