QUESTION: 184 Exam Topic: 12 Field Testing of Structured Cabling

When balanced twisted-pair copper cabling, return loss is a measurement of the:

Worst case difference in magnitude between the expected insertion loss and the actual measured insertion loss
Reflection of signal power resulting from the insertion of a device in a transmission line (in dB)
Signal coupling between any two pairs along the entire length of the cabling
Loss in signal resulting from the insertion of a component, of link, or channel, between a transmitter and a receiver
Time required for a signal to travel from one end of the transmission path to the other end

QUESTION: 185 Exam Topic: 12 Field Testing of Structured Cabling

Where backbone cabling exceeds cabling lengths for the same performance or design (for product used in horizontal cabling), there are three fundamental tests which should be considered when testing. They are:

Insertion loss (attenuation), return loss, and wiremap/strand identification
Insertion loss (attenuation), return loss, and continuity
Insertion loss (attenuation), return loss, and length
Insertion loss (attenuation), continuity, and wiremap/strand identification
Continuity, wiremap/strand identification, and propagation delay/delay skew

QUESTION: 186 Exam Topic: 12 Field Testing of Structured Cabling

You are preparing to test newly installed open office cabling. Within the open office cabling, there are multiple consolidation points (CP) that were installed while waiting for furniture. How do you proceed with permanent link testing?

Test to each CP, then test from CP to workstation.
Wait for open office cabling to be completed, then test to each workstation outlet, including the CP.
Test that the CP is within 90 meters, then test again to the workstation outlet.
Perform permanent link tests to each CP, then continuity tests from CP to each workstation outlet.
Test to each workstation outlet, treating each outlet as a channel.
