How many backbone levels are permitted in a structured cabling system?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (C)

In a structured cabling system, it is permissible to have up to three backbone levels. This structure typically consists of the main backbone, intermediate equipment rooms, and horizontal cabling. Each level plays a crucial role in facilitating efficient data transmission and networking across various parts of a building or campus, with the main backbone connecting to the main distribution frame and the intermediate levels serving to connect different areas and provide necessary media, power, or transition points. Having three backbone levels allows for greater flexibility and scalability in the network design, accommodating expansion and various building layouts without degrading performance. This configuration is essential in supporting the diverse networking needs of modern organizations, which often require robust and versatile infrastructure to handle increasing data loads and connectivity requirements. In contrast, fewer levels may limit the network's effectiveness and adaptability.
