Construction Coordinator 1 to 2 Lesson 1
Question and answers rated A+
Monitoring the status of optical nodes - correct answers Involves the use of a
node transponder that continuously monitors a number of critical functions.
Digital return path transmissions - correct answers Use dense wavelength
division multiplexing (DWDM) digital return transmitters in hub-to-headend
architectures.
Which of the following is true about optical nodes? - correct answers 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 Data Over Cable Service Interface Specification
(DOCSIS) defines the protocols for Internet protocol (IP) telephony over
hybrid fiber/coax (HFC) networks? - correct answers Packet Cable
In a centralized server video-on-demand (VOD) architecture, - correct
answers 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? - correct
answers Local ad insertion is performed usually by a video server.
In regard to providing high-speed data (HSD) service - correct answers The
cable modem termination system (CMTS) can provide a data transfer rate up
to 38 Mbps, using 256-QAM in a single 6 MHz channel.
