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

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.
