Construction Coordinator 2-3: Questions With Proven
Solutions
Which fiber-optic cable design category typically uses some star topology
variation? Correct Answer - ⦁ Signal distribution.
What is the ideal way for a broadband cable network designer to plan the
replacement of coaxial cable with fiber-optic cable to shorten amplifier
cascades? Correct Answer - ⦁ Use the existing coaxial network
infrastructure.
What is an option for a broadband cable network to maximize the use of its
optical fiber resources? Correct Answer - ⦁ Leasing spare fibers.
Which of these items should be identified on a route map so that the design
can provide (or not provide) special network access? Correct Answer - ⦁
Parks
Which type of map contains node information? Correct Answer - ⦁ Design
map.
How many meters of slack cable is typically used in an aerial installation?
Correct Answer - ⦁ 15-25 meters.
What is one example of a stipulation in a franchise agreement that would
affect network design? Correct Answer - ⦁ A 100% fiber-optic network.
When activating a fiber-optic network, which acceptance-testing stage
includes adjusting attenuation levels for the first time? Correct Answer - ⦁
During equipment activation.
What information should always be included in fiber-optic network
documentation? Correct Answer - ⦁ Fiber assignments.
When troubleshooting an outage in an optical network, why would a
technician want to refer to the network's as-built documentation? Correct
Answer - ⦁ To help determine specific cable lengths.
, What is an example of transport media in a telecommunications network?
Correct Answer - ⦁ Coaxial cable.
Which of the following describes how the signal is transported through the
network without following the physical path requirements of the peripherals?
Correct Answer - ⦁ Logical topology.
Which topology consists of a host element connected to two or more receiving
elements through a splitter or optical coupler? Correct Answer - ⦁ P2MP
(Point-to-multipoint) topology. *

routing around cities and industrial areas? Correct Answer - ⦁ Ring
What is one reason 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.
