Why might a technician refer to the network's as-built documentation when troubleshooting an outage?

Referring to the network's as-built documentation is essential for technicians when troubleshooting an outage, particularly because it includes detailed information about the specifics of the installation, such as cable lengths and types. Knowing the exact lengths of cables helps the technician understand potential issues related to signal degradation or connectivity problems. For example, if a cable is too long, it may exceed the limit for optimal performance, leading to outages or interference.

While warranty information, installation costs, and the history of the network can be useful in broader contexts, they do not directly assist in identifying or resolving the immediate technical issues that arise during an outage. The precise data about cable configurations and lengths allows for more targeted diagnostics and solutions, making it a critical part of the troubleshooting process.
