Which of the following tools allows an administrator to identify a cable?
The correct answer is C. Toner. A toner probe (tone generator and inductive amplifier) is the tool used to trace and identify an unknown cable among many runs. The tone is applied at one end and detected at the other.

Why each option
A toner probe (tone generator and inductive amplifier) is the tool used to trace and identify an unknown cable among many runs. The tone is applied at one end and detected at the other.
A multimeter measures electrical values such as voltage, continuity, and resistance, but cannot trace or identify a specific cable among many by emitting an identifiable signal.
A cable stripper mechanically removes the outer insulation from a cable to expose conductors and is a preparation tool, not a cable identification tool.
A toner consists of two components: a tone generator clipped to one end of a cable and a probe that detects the audible tone at the other end. This allows an administrator to identify and trace a specific cable through walls, ceiling spaces, or large patch panels where cables are unlabeled or bundled together.
A punch-down tool is used to terminate wires into keystone jacks or patch panels, not to identify or trace cable paths.
