The DOCSIS Media Access Control (MAC) Layer. - correct answers Which
Data over Cable Service Interface Specification (DOCSIS) layer is used by the
cable modem termination system (CMTS) to differentiate between cable
modems?


The option to increase the top frequency of the upstream to 85 MHz. - correct
answers What was introduced in Data Over Cable Service Interface
Specification (DOCSIS) 3.0 to allow enough bandwidth for upstream carriers
from previous DOCSIS versions?


Compared to the downstream path, the narrower bandwidths and lower orders
of modulation used to transport data over the return path cause the
downstream and upstream data throughput to be unequal or asymmetrical. -
correct answers In a Data Over Cable Service Interface Specification
(DOCSIS) network, why is the data throughput over the return or upstream
path typically less than the throughput of data over the forward or downstream
path?


76 Mbps. - correct answers What would be the downstream throughput if two
quadrature amplitude modulation (QAM) channels with a throughput of 38
megabits per second (Mbps) were bonded?


Orthogonal frequency division multiplexing (OFDM) and low-density parity-
check (LDPC). - correct answers What are two features that were added in
Data Over Cable Service Interface Specification (DOCSIS) 3.1 to extend the
viability of hybrid fiber/coax (HFC) networks into the next decade?
