NCTI Exam I Questions and Answers
100% Pass
In the tree-and-branch architecture, how is the downstream signal from the trunk fed
to the distribution branches? - ✔✔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? - ✔✔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? - ✔✔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? - ✔✔The legend at the bottom of the network design
map that defines the map symbols, cable types, and amplifier data.
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
How can a distribution amplifier be identified in the network or on a network design
map? - ✔✔The distribution amplifier has multiple downstream outputs.
