Question

  19% (9)
• C
  8% (4)

Explanation

In TIA-568 structured cabling, a horizontal cabling channel represents the complete end-to-end path from active equipment in the Telecommunications Room (TR) all the way to the device at the Work Area (WA). A link is a subset of that path - it strips off both ends, excluding the equipment patch cords at the TR (A) and the work area cords plugged into the device beyond the telecommunications outlet/connector (D). These two components belong to the channel measurement but not the link measurement, which is why A and D are correct.

Why B and C are wrong: Consolidation Points (CP) and Transition Points (TP) are part of the horizontal cable infrastructure itself - they can appear inside both a link and a channel. They are not what distinguishes one from the other, so "does not include a CP/TP" is not a valid differentiator.

Memory tip: Think of the link as the permanent infrastructure - the stuff installed in the walls and ceilings that doesn't change. The channel adds the cords at both ends that connect active equipment to user devices. Link = infrastructure only; Channel = infrastructure + both sets of connecting cords.
