Assume the following:
- An equipment room (ER) consists of 16 racks arranged in 4 equal rows
- The first 4 racks are numbered R1-1 though R1-4
- The second 4 racks are numbered R2-1 through R2-4
- A new equipment shelf with 12 slots is to be installed in the bottom of the third rack in the second row
- Each slot has 2 ports
What would be the identifier of the two ports on the eighth slot of the new equipment shelf?

  1. R2-3-1-8-1 and R2-3-1-8-2
  2. R3-2-1-8-1 and R3-2-1-8-2
  3. R2-3-1-12-1 and R2-3-1-12-2
  4. R3-2-1-12-1 and R3-2-1-12-2
  5. R2-3-12-8-1 and R2-3-12-8-2

Answer(s): A

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

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

Answer(s): B



You have been asked to test and troubleshoot an installed base of cabling that is believed to be causing network problems. You are finding that there are high levels of return loss upon initial testing.
What testing will best determine the reasons for these failures?

  1. Power meter
  2. Continuity testing
  3. Level II testing
  4. Time domain reflectometer (TDR)

Answer(s): D
