-When a pre-connectorized fiber is not attached to equipment, what should
be attached to help keep it clean? - -A dust cap
-Simplify and solve the equation: If E = IR then I = ? - -E/R
-(480 x 10 to the power of -5) divided by (60 x 10 to the power of -3) = - -8
x 10 to the power of -2
-7 3/8 divided by 7 1/4 = - -1 1/58
-(20) / (-4) + (-2) x (-10) - (-2) x (7) = - -29
-What should you avoid to prevent stress? - -Excessive caffeine

-During which step of the six-step troubleshooting process for a digital TV
(DTV) service problem are quadrature amplitude modulation (QAM) channel
measurements typically taken? - -Diagnosing symptoms.
-When troubleshooting a digital TV (DTV) authorization issue, what can be
verified using the set-top box (STB) diagnostic page? - -STB reception of
authorization message data.
-Which of the following is a multicast control protocol between the cable
modem and the CMTS that works in harmony with the downstream channel
bonding for efficient and extensible support for multicast applications? - -

transmitter's power level and sends the signal to the antenna. The antenna
receives the signal from the amplifier at 75 mW, and then transmits at 150
mW. What is the intentional radiator's (IR) power level in this radio frequency
(RF) circuit? - -75 mW
