Internet via their HFC networks using what standard? - (ANSWER)DOCSIS
What is MPEG? - (ANSWER)A universally accepted standard for digital television, first
released in 1992.
Which of the following is true about optical nodes? - (ANSWER)They contain four main
sections: the optical receiver, the RF amplifier module, the reverse optical transmitter, and the
DC power supply.

What product based on the DOCSIS defines the protocols for IP telephony over HFC? -
(ANSWER)PacketCable
In a centralized server VOD architecture, - (ANSWER)The number of servers needed for video
content storage is smaller than in the distributed server architecture.
Which of the following statements about local ad insertion is true? - (ANSWER)Local ad
insertion is performed usually by a video server.
In regard to providing HSD service, - (ANSWER)The CMTS
Cable modem termination system
can provide a data transfer rate up to 38 Mbps, using 256-QAM in a single 6 MHz channel.
Which of the following is true about the SONET standard? - (ANSWER)SONET is the North
American standard used for telephony applications.
Compared to a solid copper center conductor, which property about a copper clad aluminum
(CCA) center conductor is correct? - (ANSWER)The CCA center conductor has almost equal
attenuation at high frequencies.

In hardline coaxial cable, what is the most common dielectric material? - (ANSWER)Foamed
polyethylene produced by gas injection.
In aerial installations, why do cable manufacturers recommend that expansion loops be formed in
hardline coaxial cable? - (ANSWER)To allow movement of the cable when lashed to the strand
Why was the impedance for the broadband cable industry standardized at 75 ohms (Ω)? -
(ANSWER)At 75 Ω characteristic impedance, the coaxial cable has minimal attenuation, with
adequate breakdown voltage and power carrying capacity.
What is the coaxial cable velocity of propagation (VoP)? - (ANSWER)The rate that radio
frequency (RF) signals travel through the coaxial cable versus the speed that RF signals travel in
a vacuum or free space.
If the attenuation through a 100 ft. span of 0.750 MC2 coaxial cable is 2.5dB at 75 MHz, what
will be the approximate attenuation at 300 MHz? - (ANSWER)2 x 2.5 dB, or 5.0 dB.
