Ans. CAT6
Cat5E can run Gig Ethernet but Gig does push the limits of Cat5E.
If I was re-cabling the building then I would run CAT6 for everything as the cost difference is not that great. CAT6 will help with any longer runs
Cat 5E is not an option here so Cat6 is most likely ans

Toner Generator and Probe
The toner generator and probe, as shown in Figure 3, is a two-part tool. The toner part is connected to a cable at one end using specific adapters. The toner generates a tone that travels the length of the cable. The probe part traces the cable. When the probe is in near proximity to the cable to which the toner is attached, the tone can be heard through a speaker in the probe.

D. Cable tester
Multimeter - A device that measures AC/DC voltage, electric current, and other electrical characteristics.
Power supply tester - A device that checks whether the computer power supply is working properly. A simple power supply tester might just have indicator lights, while more advanced versions show the amount of voltage and amperage.
Cable tester - A device that checks for wiring shorts, faults, or wires connected to the wrong pins.
Toner probe part traces the cable, requires toner generator too
Loopback plug - A device that connects to a computer, switch, or router port to perform a diagnostic procedure called a loopback test. In a loopback test, a signal is transmitted through a circuit and then returned to the sending device to test the integrity of the data transmission.
