C-NNIC case studies

The Certified Network Infrastructure and Cabling credential, commonly shortened to C-NNIC, is an independent certification aimed at professionals who build and maintain the physical layer of enterprise networks: cabling installers, infrastructure technicians, field engineers, and the planners who design pathways, spaces, and racks. It tests whether a candidate can reason across the whole physical plant rather than recite a single vendor's product line, covering structured cabling topology and wiring, infrastructure design, media and physical-layer standards, installation practice and cable management, testing and troubleshooting, codes and safety, plus racks, power, and cooling. The C-NNIC case studies are 5 cases and about 4,775 words.
