AP can provide power supply and data transmission through POE switch.

Question

Options

• ATrue
• BFalse

• A
  73% (36)
• B
  27% (13)

Explanation

Option A is correct because PoE (Power over Ethernet) technology is specifically designed to deliver both electrical power and network data over a single Ethernet cable simultaneously. A PoE switch identifies PoE-capable devices like wireless access points and supplies the required voltage through the same cable used for data transmission, removing the need for a separate power adapter or nearby electrical outlet. This makes PoE switches particularly useful for deploying APs in locations where running a power cable would be difficult or costly.

Option B is incorrect because it contradicts the core purpose of PoE technology - the entire point of a PoE switch is to combine power delivery with data transfer over one cable.

Memory tip: Break down the acronym - Power over Ethernet means power travels over the same Ethernet connection used for data, so a PoE switch handles both functions at once for supported devices like APs.
