Where can a less-experienced technician find the meaning of non-standard symbols on network design maps?

The correct answer is found in referring to the legend at the bottom of the map. Most network design maps include a legend or key that explains the various symbols and icons used throughout the document. This legend is specifically designed to provide clarity on how to interpret the information presented, ensuring that technicians, regardless of their experience level, can accurately understand the representations on the map.

While consulting the project manager, asking senior technicians, or searching for online resources might also yield useful information, these methods can take more time and effort and may not lead to immediate clarity. The legend provides a direct and efficient way to understand the specific symbols used in that particular map. Thus, utilizing the legend is the most straightforward and effective approach for less-experienced technicians looking to interpret non-standard symbols.
