Conventional UPDATED ACTUAL Exam
Questions and CORRECT Answers
A plant's roots transport water and nutrients from underground to the leaves and stems above
ground and vice versa to supply the plant with its necessities. What comparison could be made
between a broadband system and a plant?
A broadband system transports data through and between its aerial and underground plants to
supply its customers with necessary services. - CORRECT ANSWER -
What does the following symbol represent?
A slack span that is 49 feet long. - CORRECT ANSWER -
What connects two adjacent poles to provide additional stability and support?
Pole - to - pole guy - CORRECT ANSWER -
What does the following symbol represent?
A 90-foot routing bore. - CORRECT ANSWER -
What cable primarily aims to transport signals from the optical node or the headend to different
parts of the network without serving individual homes or customers along the way?
875" Coaxial cable. - CORRECT ANSWER -
Which active RF device has one RF input with several RF output ports, allowing it to split and
amplify the RF signal for distribution across multiple coaxial cables?
,Multiple output amplifier - CORRECT ANSWER -
What does the small dot on this line splitter symbol indicate?
The thru leg of the internal directional coupler - CORRECT ANSWER -
What does the following symbol represent on a PON system map?
OTE (optic terminal enclosure) - CORRECT ANSWER -
What does this symbol represent on a PON system map?
A device that increases the optical power of an input light signal without converting it to an
electrical RF signal. - CORRECT ANSWER -
What does this symbol represent?
Mid-entry splice - CORRECT ANSWER -
Standby power supply with housing
Essential for providing backup power in case of utility power failure. It ensures that the HFC
system continues to function during power outages. Standby power supplies often rely on
batteries or generators to deliver uninterrupted power, preventing customer service disruption. -
CORRECT ANSWER -
In the tree-and-branch architecture, how is the downstream signal from the trunk fed to the
distribution branches?
,Within each trunk amplifier, a portion of the downstream is fed to a Bridger amplifier to boost
the signal before being split and routed to the distribution branches. - CORRECT ANSWER -
What is a common solution when congestion from modem activity and traffic becomes
unacceptable in a HFC network?
Node splitting, the subdividing of serving areas into two or more smaller serving areas. -
CORRECT ANSWER -
What technologies are defined in DOCSIS 4.0 to help sustain the HFC network infrastructure for
several more years?
FDX (Full Duplex DOCSIS) and ESD (Extended Spectrum DOCSIS) - CORRECT
ANSWER -
How can a less-experienced technician identify what non-standard symbols on the network
design maps represent?
The legend at the bottom of the network design map that defines the map symbols, cable types,
and amplifier data. - CORRECT ANSWER -
What is the RF distribution tap value indicated on the tap face plate by a sticker or number
stamped into the housing?
The signal loss between the tap downstream input port and the tap ports. - CORRECT
ANSWER -
How can a distribution amplifier be identified in the network or on a network design map?
The distribution amplifier has multiple downstream outputs. - CORRECT ANSWER -
, What is spliced into the hardline coaxial cable to combine the AC power with the transported RF
signal in a hybrid fiber/coax (HFC) network?
A power inserter. - CORRECT ANSWER -
What test instrument sends out a test signal and displays any reflections caused by impedance
mismatches in the cable that are characteristic of cable faults?
TDR (Time Domain Reflectometer) - CORRECT ANSWER -
What should you be looking for when analyzing the network design maps to troubleshoot a
problem?
The device common to those customers affected before traveling to make signal status checks. -
CORRECT ANSWER -
What is required for checking the physical network integrity when maintaining the coaxial cable
network?
Being observant and performing some minor tasks while engaged in regularly scheduled
activities. - CORRECT ANSWER -
What is an example of transport media in a telecommunications network?
Coaxial cable. - CORRECT ANSWER -
Which of the following describes how the signal is transported through the network without
following the physical path requirements of the peripherals?
