PoE exclusively functions over ___ because the powered devices are localized.

• A. Wireless Area Networks (WANs)
• B. Category 5 cable
• C. a server
• D. Local Area Networks (LANs)

Answer: (D)

Power over Ethernet delivers DC power over the same Ethernet cabling that carries data, and it’s designed for devices that sit close to the network infrastructure. The powered devices are typically located near a switch or injector within a building or campus, so PoE operates within a Local Area Network. Ethernet copper links have practical distance limits (about 100 meters) and the power budgets are modest, which fits the LAN environment best. Wide Area Networks span much larger distances and aren’t the intended setting for PoE power delivery. The media used is Ethernet cabling (like Cat5/Cat6), reinforcing that this is a LAN-focused capability.
