Which media-to-scenario pairing correctly matches typical enterprise networking usage?

• A. Copper cables: backbone cabling in an enterprise; Wireless: guest access in a coffee shop
• B. Fiber optic: guest access in a coffee shop; Wireless: backbone cabling in an enterprise
• C. Copper cables: horizontal cabling structure, desktop PCs in an enterprise office; Fiber optic: backbone cabling in an enterprise, long-haul networks; Wireless: guest access in a coffee shop, waiting rooms in a hospital
• D. Copper cables: waiting rooms in a hospital; Fiber optic: long-haul networks; Wireless: desktop PCs in an enterprise office

Answer: (D)

Media types map to how networks are laid out in real buildings: copper for short, cost-effective runs to user devices, fiber for high-bandwidth backbone and long-haul links, and wireless for providing access where wiring every device isn’t practical or desirable.

Copper cables are ideal for horizontal cabling that connects desktop PCs and other end-user devices to switches within an office. This keeps the connection close to the user and avoids the distance and bandwidth limitations of longer copper runs.

Fiber optic is chosen for backbone cabling and long-haul networks because it supports much higher bandwidth over greater distances with less signal loss. It naturally fits links between floors, buildings, or data centers, where the network core needs fast, reliable transport.

Wireless is used to give devices access without physical cables, which is especially useful for guest access or visitor devices in public or semi-public areas like coffee shops and hospital waiting rooms. It provides flexibility and easy connectivity for devices that don’t sit neatly on a wired desk.

Putting these together, copper supports horizontal office cabling to desktops, fiber handles backbone and long-haul connections, and wireless serves guest or public-area access. This aligns with the paired scenario described for typical enterprise usage.
