NCTI FINAL EXAM: PROGRESSION FIELD TECH 2 -
3 TEST EXAM| LATEST UPDATE | Complete
Solutions Field Tech II - III Conventional.

What is one reason why broadband cable operators install fiber optic cables in stages instead of
changing the infrastructure all at once

Changing the infrastructure all at once would cause too many service disruptions

What is the difference between FTTN and FTTC

FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises

Which of these components is used in a PON(Passive Optical Network)

Optical Splitters

Which type of Star topology used in a PON(Passive Optical Network) places the PON splitters into
FATS(Fiber Access Terminals) located deep in the network and closer to the customer premises than
the centralized split

Distributed Star

Which element of a PON(Passive Optical Network) uses a Bragg grating filter

OLT(Optical Line Terminal)

Which element of a PON(Passive Optical Network) uses Patch Panels

ODN(Optical Distribution Network)

What is it about Radio Frequency over Glass(RFoG) that made broadband cable operators envision
using it to make a seamless transition from the legacy hybrid/fiber coax(HFC) architecture over to a
gigabit-capable passive optical network (GPON) or Ethernet passive optical network (EPON)

RFoG can operate in parallel with GPON or EPON, which eliminates the need for any downtime during
the transition

How are optical splitters used in the forward path

In the forward path, optical splitters are used as passive branching devices that divide an optical signal
across multiple output fibers

Which of the following describes a fiber pigtail

Fiber-optic cable with pre-connectorized ends

Heat Shrink tubing is installed over the fusion-splice to strengthen and protect it. When should the
heat shrink be installed on the fiber

Before stripping the plastic coating from the fiber

,Which of the following is a method for controlling expectations

focus on the bigger picture rather than smaller tasks

Which of the following best describes stereotyped thinking

Presuming that all members of a group have certain characteristics

The attribute of being "active" as a critical thinker means

You observe and take notes relevant to the issue

What kind of reasoning is described as applying a general statement that you know to be true to a
new situation

Deductive

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

A significant change in attitude with a noticeable movement toward negative, hostile, cynical, or
paranoid thoughts

You are at a customer's house and you are asking the customer whether the problem is intermittent or
constant. Which step are you using from the six-step troubleshooting process

Identifying the problem

Why should you take the time to take notes and accurately record data at each job location

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

You are at a customer's home and you believe you have solved the problem. When you check to be
sure there are no new problems, which step are you using

Verifying 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 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
QAM(Quadrature amplitude modulation) 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 tech's confidence that the problem will be resolved by replacing the splitter

Which of the following DTV(digital TV) 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

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

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 Data Over Cable Service Interface Specification (DOCSIS) layer is used by cable modem
termination system (CMTS) to differentiate between cable modems

the DOCSIS Media Access Control (MAC) Layer

What was introduced in Data Over Cable Service Interface Specification(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 85MHz
