Question 1

What is the primary purpose of a tone generator and inductive amplifier (toner/probe) set in cabling work?

Accepted Answer

To trace and identify cables without cutting into walls

Answer

A tone generator sends a signal through a cable and the inductive amplifier (probe) detects it through walls and conduit, allowing installers to trace and identify specific cables.

Question 2

Which cable stripping technique is recommended to avoid damaging the conductors inside a UTP cable?

Accepted Answer

Use a cable stripper set to the correct depth to remove only the outer jacket

Answer

A properly adjusted cable stripper removes only the outer jacket without nicking the insulation or conductors beneath, which could cause continuity faults.

Question 3

When using a cable certification tester, what does a 'FAIL' result on the 'Return Loss' parameter indicate?

Accepted Answer

Too much signal is being reflected back toward the source due to impedance mismatches

Answer

Return Loss measures the amount of signal reflected back due to impedance discontinuities; a FAIL means excessive reflection that will degrade network performance.

Question 4

What type of saw is most appropriate for cutting a clean rectangular opening in drywall for a low-voltage mounting bracket?

Accepted Answer

Oscillating multi-tool or drywall saw

Answer

An oscillating multi-tool or drywall keyhole saw gives controlled, clean cuts for outlet openings without the risk of overcutting or damaging adjacent materials.

Question 5

A fish tape becomes kinked and difficult to retract. What is the correct corrective action?

Accepted Answer

Straighten the kink carefully by hand and store the tape properly coiled in the reel

Answer

Kinks in fish tape can be carefully straightened and the tape stored properly; severe kinks may require the tape to be replaced to prevent breakage during use.
