Why label both ends of a cable?

• A. To decorate cables with labels.
• B. To map endpoints quickly, prevent mispatching, and speed audits/troubleshooting.
• C. To determine the color of fiber.
• D. To determine the connector gender.

Answer: (B)

Labeling both ends of a cable gives you a reliable way to map endpoints end-to-end, prevent mispatching, and speed audits and troubleshooting. In busy data centers with many cables running between devices, patch panels, and switches, a label on only one end can disappear or get obscured, making it easy to lose track of where a cable actually goes. When both ends carry matching labels, you can quickly verify that the same circuit connects the intended devices and ports, trace it during fault isolation, and confirm changes during audits. This reduces the chance of plugging into the wrong port and accelerates repair or reconfiguration work. The other options don’t address how cables are tracked or traced, and labeling isn’t about decoration, fiber color, or connector gender.
