NCTI Exam I Questions And Answers
In the tree-and-branch architecture, how is the downstream signal
from the trunk fed to the distribution branches? -
correct answer ✅A portion of the downstream is fed to a bridger
amplifier to boost the signal before being split and routed to the
distribution branches.
What is a common solution when congestion from modem activity
and traffic becomes unacceptable in a hybrid fiber/coax (HFC)
network? -
correct answer ✅Node splitting, the subdividing of serving areas
into two or more smaller serving areas.
What technologies are defined in DOCSIS 4.0 to help sustain the
hybrid fiber/coax (HFC) network infrastructure for several more
years? -
correct answer ✅Full Duplex DOCSIS (FDX) and Extended
Spectrum DOCSIS (ESD).
How can a less-experienced technician identify what non-standard
symbols on the network design maps represent? -
correct answer ✅The legend at the bottom of the network design
map that defines the map symbols, cable types, and amplifier data.
, NCTI Exam I Questions And Answers
What is the RF distribution tap value indicated on the tap face plate
by a sticker or number stamped into the housing? -
correct answer ✅The signal loss between the tap downstream
input port and the tap ports
How can a distribution amplifier be identified in the network or on
a network design map? -
correct answer ✅The distribution amplifier has multiple
downstream outputs.
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? -
correct answer ✅A power inserter.
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? -
correct answer ✅Time domain reflectometer (TDR)
What should you be looking for when analyzing the network design
maps to troubleshoot a problem? -
correct answer ✅The device common to those customers affected
before traveling to make signal status checks.
