Name: Score:129 Multiple choice questions
Term 1 of 129
When using a signal level meter and half wave dipole antenna to check signal leak at 3 meters,
the SLM
Must be waterproof to ensure functionality in all weather conditions
Should only measure frequencies above 100 mhz for accuracy
Can only detect signal levels above 50 uv/m for reliable readings
Must be capable of measuring signal levels as low as 20 uV/m or -40dBmV
Term 2 of 129
Which type of video-on-demand (VOD) refers to a service where users can buy a particular
piece of VOD content on a pay-per-view (PPV) basis?
Take essential notes.
The cable and telecommunication association for marketing
Quadrature amplitude modulation (qam).
Transactional video-on-demand (TVOD).
Term 3 of 129
A Single beam TV receive only antenna:
Hardware and software at the headend transmit the signals and keep track of events and
transactions.
Has a parabolic shape that reflects the downlink signal from all locations on the dish
surface onto a central focal point, which collects the reflections and provides maximum
signal reception
A rate cap based on the level of service (throughput) of each customer purchase is sent
to each cable modem when it is connected to the system
Balancing amplifier levels, sweeping of frequency responses, monitoring power
supplies, and conducting proof-of-performance testing
,Term 4 of 129
One difference between frequency modulation and amplitude modulated link techniques in
microwave signal transmission is that
Fm is used for digital signals, while aml is used for analog signals
FM transmits a single channel, and AML sends blocks of broadband channels between
headends and hubs.
Fm requires more bandwidth than aml for transmission
Fm and aml both transmit multiple channels simultaneously
Term 5 of 129
In plain old telephone service (POTS) the (BLANK) is a pair of wires connecting the customer
location to the telephone company
Premium service
High definition
Dispatch
Local circuit loop
Term 6 of 129

4k is exclusively used for gaming consoles.
UHD is a consumer display and broadcast standard.
4k is a standard for audio quality in televisions.
Uhd refers to the resolution of mobile devices only.
,Term 7 of 129

The National Broadband Plan (NBP) of 2010
The internet freedom act of 2012
The digital divide initiative of 2005
The telecommunications deregulation act of 1998
Term 8 of 129
What signal modulation technique do broadband cable operators use to transport digital
television (DTV) signals through the cable network?
Quadrature amplitude modulation (QAM).
A power inserter.
Frequency-hopping spread spectrum.
A digital terminal adapter (dta).
Term 9 of 129
The data over cable services interface specification (DOCSIS) system security component,
baseline privacy interface plus (BPI+), protects customers data in the following ways:
FM transmits a single channel, and AML sends blocks of broadband channels between
headends and hubs.
The legend at the bottom of the network design map that defines the map symbols,
cable, types, and amplifier data.
BPI+ encrypts packet data across the cable network and provides secure distribution of
synchronized keying data from the CMTS to the cable modems to enforce conditional
access to network services.
Within each trunk amplifier, a portion of the downstream is fed to a bridger amplifier to
boost the signal before being split and routed to the distribution branches.
, Term 10 of 129
What is required for checking the physical network integrity when maintaining the coaxial
cable network?
Only checking the network during scheduled maintenance days.
Being observant and performing some minor tasks while engaged in regularly
scheduled activities.
