COMPLETE 230 ACTUAL EXAM QUESTIONS
AND CORRECT ANSWERS (VERIFIED
ANSWERS) ALREADY GRADED A+.
Name three bonding solutions.
Fargo clamp, Galvanized bonding strap, IBT (intersystem
bonding terminal)
A VOM connected to a piece of RG-6 cable shows a resistance
of 12 ohms, how long in feet is the RG'6 cable? What process do
you use to find this?
DC loop resistance
If the electrical meter is 45' away from the home you may use a _.
Trailer beam clamp
Name the components of a typical coax cable.
jacket, braiding/shielding, dielectric, center conductor
,Red and green in UTP go to which pair in CAT-6?
blue and blue/white. red goes to blue. green goes to blue/white.
Would it be acceptable to bond a copper ground strap on a
galvanized pipe?
No, it would corrode. The rule of thumb is like metals with like
metals.
Self install kit/factory fittings inside the home must be finger
tight or torque tight?
finger tight
Give one example of a passive device.
spliter, it does not require power
Give one example of an active device.
amplifier or any cpe. they require power.
What passive device can be installed on a drop that will block
services by attenuating certain frequencies more than other?
A Negative Trap
,What does DOCSIS stand for?
Data over cable service interface specifications
How wide is a signal analog channel?
6 MHZ wide, Only 1 analog channel can fit, and 8-12 digital
channels due to compression
What is the purpose of channel bonding?
it increases throughput or bandwidth. came out with DOCSIS 3.0
What modulation scheme uses two waveforms phase shifted 90°
apart on identical frequencies?
QAM
What is the relative measurement between two absolute points?
decibel (dB)
, When an ISA's internal gains equal it's passive losses, then what is
the result on the output?
0 gain
Define 1 Hertz
1 cycle per 1 second
what does a signal of 0 dBmV mean?
1 milli-volt measured across 75 ohms of impedance
if you discover an issue with power or ground, what would be your
next steps?
stop work, notify your supervisor and customer.
