Atechnician has verified that a recent loss of network connectivity to multiple workstations is due
to a bad cat5 cable in the server room wall. which of the following tools can be used to locate its
physical location within the wall?
a. cable certifier
b. multimeter
c. cable tester
d. toner probe

D. Toner probe

Explanation:

The tone probe allows you to apply a tone signal to a pair of wires or a single conductor, while the trace is done with an amplified probe. When used in conjunction with the amplified probe, the tone generator allows technicians to identify a wire within any beam, at cross connections or at remote ends. You can use twisted pair, coaxial and disconnected AC wiring.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
