What is one reason why broadband cable operators install fiber-optic cable in
stages instead of changing the infrastructure all at once? Correct 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? Correct 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)?
Correct 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? Correct
Ans - Distributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter?
Correct Ans - Optical line terminal (OLT).
Which element of a passive optical network (PON) uses patch panels?
Correct 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)? Correct
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? Correct 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? Correct 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? Correct Ans -
Before stripping the plastic coating from the fiber.
Which of the following are statements of true axioms? Correct 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 = ? Correct Ans - E/R
The square of 7 = Correct Ans - 49
The square root of 81 = Correct Ans - 9
0.00004 = ______ x 10 to the power of ______. Correct Ans - 4, -5
(75 x 10 to the power of 3) + (25 x 10 to the power of 4) = Correct Ans -
32.5 x 10 to the power of 4
10 to the power of -3 has a metric prefix of ______. Correct Ans - Milli
(480 x 10 to the power of -5) divided by (60 x 10 to the power of -3) =
Correct 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) = Correct Ans -
180 x 10 to the power of -6
(75 × 103) + (25 × 104) = Correct Ans - (*Wrong) 100 × 10^3
(-25) + (42) + (-62) + (20) = Correct Ans - -25
(17) x (-19) = Correct Ans - -323
(-17) - (-34) = Correct Ans - 17
-49/-7 = Correct Ans - 7
, (20) / (-4) + (-2) x (-10) - (-2) x (7) = Correct Ans - 29
3 6/9 + 6 1/3 + 9 5/9 = Correct Ans - 19 5/9
4/7 x 9 4/11 = Correct Ans - 5 27/77
7 3/8 divided by 7 1/4 = Correct Ans - 1 1/58
8.13 X 0.123 = Correct Ans - 0.99999
0.5349 divided by 0.1420 = Correct Ans - 3.7669014
Which of the following is a method for controlling expectations? Correct
Ans - Identify the source of emotional overload.
Which of the following best describes stereotyped thinking? Correct Ans -
Presuming that all members of a group have certain characteristics.
The attribute of being "active" as a critical thinker means Correct Ans -
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? Correct Ans - 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? Correct Ans - 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? Correct Ans - Identifying the problem.
Why should you take the time to take notes and accurately record data at each
job location? Correct Ans - 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.
