PROGRESSION FINAL EXAM 2025/2026
QUESTIONS AND ANSWERS 100% PASS
What uses the 2.4-GHz band and runs at 54 Mbps? - ANS 802.11g
What is one reason why broadband cable operators install fiber-optic cable in stages instead of
changing the infrastructure all at once? - ANS 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? - ANS 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)? - ANS 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? - ANS Distributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter? - ANS Optical
line terminal (OLT).

,Which element of a passive optical network (PON) uses patch panels? - ANS 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)? - ANS 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? - ANS 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? - ANS 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? - ANS Before stripping the plastic coating from the
fiber.
Which of the following are statements of true axioms? - ANS 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 = ? - ANS E/R
The square of 7 = - ANS 49
The square root of 81 = - ANS 9

(75 x 10 to the power of 3) + (25 x 10 to the power of 4) = - ANS 32.5 x 10 to the power of 4
10 to the power of -3 has a metric prefix of ______. - ANS Milli
(480 x 10 to the power of -5) divided by (60 x 10 to the power of -3) = - ANS 8 x 10 to the
power of -2
(250 x 10 to the power of -6) - (7 x 10 to the power of -5) = - ANS 180 x 10 to the power of -6
(75 × 103) + (25 × 104) = - ANS (*Wrong) 100 × 10^3
(-25) + (42) + (-62) + (20) = - ANS -25
(17) x (-19) = - ANS -323
(-17) - (-34) = - ANS 17
-49/-7 = - ANS 7
(20) / (-4) + (-2) x (-10) - (-2) x (7) = - ANS 29
3 6/9 + 6 1/3 + 9 5/9 = - ANS 19 5/9
4/7 x 9 4/11 = - ANS 5 27/77
