which of the following is a wiring scheme for copper idc terminations?

The correct wiring scheme for copper IDC terminations from the typical options given is T568B (often mis-typed in questions as “T468B”).

Key point

• For twisted-pair copper cabling using IDC (punch-down) terminations, the predominant standardized wiring schemes are T568A and T568B.

• Where a multiple-choice option like “T468B” appears, it almost always refers to the standard T568B wiring scheme, which is widely used for data networks and IDC terminations.

• Another scheme you may see in options is USOC , which is a recognized wiring scheme but is mainly associated with voice/telephony, not the primary modern data cabling standard.

Answer in exam-style terms: choose the option that corresponds to T568B (even if it is written as “T468B” in the choices).
