Final answer:
To manage and troubleshoot network cabling issues, you would use a cable tester, tone generator and probe, and fiber optic tester for continuity, tracing, and checking polarity respectively.
Step-by-step explanation:
The subject of the question pertains to the tools used for network cable management and troubleshooting in Computers and Technology. If you're dealing with continuity, fiber or cable tracing, or checking duplex connector polarity, you would use a cable tester for continuity checks, a tone generator and probe for tracing cables, and a fiber optic tester to check the polarity of fiber optic connections.
These tools help identify if cables are properly connected and functioning, locate the path or route of a particular cable, and ensure fiber optic connectors are aligned correctly for data transmission.
