NCTI FIELD TECH 2 TO 3
PROGRESSION FINAL EXAM 2026
Questions and Answers
What uses the 2.4-GHz band and runs at 54 Mbps? - Correct 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? - Correct 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? - Correct 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)? - Correct
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? - Correct answer-
Distributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter? -
Correct answer-Optical line terminal (OLT).
Which element of a passive optical network (PON) uses patch panels? - Correct
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)? - Correct 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? - Correct 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? - Correct 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? - Correct answer-Before
stripping the plastic coating from the fiber.
Which of the following are statements of true axioms? - Correct 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.
Simplify and solve the equation: If E = IR then I = ? - Correct answer-E/R

The square root of 81 = - Correct answer-9
0.00004 = ______ x 10 to the power of ______. - Correct answer-4, -5
(75 x 10 to the power of 3) + (25 x 10 to the power of 4) = - Correct answer-32.5 x
10 to the power of 4
10 to the power of -3 has a metric prefix of ______. - Correct answer-Milli
(480 x 10 to the power of -5) divided by (60 x 10 to the power of -3) = - Correct
answer-8 x 10 to the power of -2
(250 x 10 to the power of -6) - (7 x 10 to the power of -5) = - Correct answer-180 x
10 to the power of -6

, (75 × 103) + (25 × 104) = - Correct answer-(*Wrong) 100 × 10^3
(-25) + (42) + (-62) + (20) = - Correct answer--25
(17) x (-19) = - Correct answer--323
(-17) - (-34) = - Correct answer-17
-49/-7 = - Correct answer-7
(20) / (-4) + (-2) x (-10) - (-2) x (7) = - Correct answer-29
3 6/9 + 6 1/3 + 9 5/9 = - Correct answer-19 5/9
4/7 x 9 4/11 = - Correct answer-5 27/77
7 3/8 divided by 7 1/4 = - Correct answer-1 1/58
8.13 X 0.123 = - Correct answer-0.99999
0.5349 divided by 0.1420 = - Correct answer-3.7669014
Which of the following is a method for controlling expectations? - Correct answer-
Identify the source of emotional overload.
Which of the following best describes stereotyped thinking? - Correct answer-
Presuming that all members of a group have certain characteristics.
