Which cable serves as the backbone path between floors in a building?

• A. Backbone Cable
• B. Riser Cable
• C. Premises Wiring
• D. Conduit Piston

Answer: (B)

Riser cabling is the vertical path that runs between floors, carrying the main network traffic up and down through a building. It typically traverses riser shafts or conduits and connects the telecommunications rooms on each floor, making it the backbone path that links floors together. This cabling is designed with fire-rated features to meet building-code requirements for vertical runs. Premises wiring describes cables confined to a single floor, not the inter-floor backbone. Conduit piston isn’t a standard term in this context, and while backbone cabling is a general idea, the specific vertical inter-floor path is the riser cable.
