NCTI FIELD TECH 2 TO 3 PROGRESSION FINAL EXAM
WITH 100% REAL ANSWERS
What uses the 2.4-GHz band and runs at 54 Mbps? - (ANSWER)802.11g
What is one reason why broadband cable operators install fiber-optic cable in stages instead of
changing the infrastructure all at once? - (ANSWER)Changing the infrastructure all at once
would cause too many service disruptions.
What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC)
topologies? - (ANSWER)An 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 passive optical network (PON)? - (ANSWER)Optical
splitters.
Which type of star topology used in a passive optical network (PON) places the PON splitters
into fiber access terminal (FAT) located deep in the network and closer to the customer premises
than the centralized split? - (ANSWER)Distributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter? -
(ANSWER)Optical line terminal (OLT).
Which element of a passive optical network (PON) uses patch panels? - (ANSWER)Optical
distribution network (ODN).
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)? - (ANSWER)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? - (ANSWER)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? - (ANSWER)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? - (ANSWER)Before stripping the plastic coating from
the fiber.
Which of the following are statements of true axioms? - (ANSWER)When A = C and B = C,
then A = B because both are equal to C, which supports the axiom: Quantities equal to the same
quantity are equal to each other.

power of -2
(250 x 10 to the power of -6) - (7 x 10 to the power of -5) = - (ANSWER)180 x 10 to the power

members of a group have certain characteristics.
The attribute of being "active" as a critical thinker means - (ANSWER)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? - (ANSWER)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? - (ANSWER)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 are asking the customer whether the problem is
intermittent or constant. Which step are you using from the six-step troubleshooting process? -
(ANSWER)Identifying the problem.
Why should you take the time to take notes and accurately record data at each job location? -
(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.
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 problems, which step are you using from the
six-step troubleshooting process? - (ANSWER)Verifying the solution.
To break the habit of a negative self-talk cycle - (ANSWER)Tell yourself "not now" and move
onto a positive thought whenever negative thoughts occur.
By taking control of the expectations you have, you are - (ANSWER)More likely to improve
your motivation and be a better problem solver.
Which of the following characterizes the successful troubleshooter? - (ANSWER)Someone with
an inquisitive and relentless desire to solve and fix problems.
