The correct answer is A. PoE. Power over Ethernet (PoE) allows a network switch to deliver electrical power to connected devices through standard Ethernet cabling (CAT5e or better).

Question
A small office home office (SOHO) customer is going to be replacing their switch. The customer also wants to add a WAP in a dropped ceiling; however, there are no power outlets above the drop ceiling, but there is a CAT5e network jack. Which of the following technologies should the new switch have to allow this WAP to be placed where the customer requests, without any other major changes to the environment?
Options
- APoE
- BLayer 3 switching
- CSTP
- DVLAN

Explanation
Power over Ethernet (PoE) allows a network switch to deliver electrical power to connected devices through standard Ethernet cabling (CAT5e or better). This means a WAP (Wireless Access Point) can receive both data and power through a single Ethernet cable, eliminating the need for a separate electrical outlet. Layer 3 switching enables routing functions but does not address the power problem. STP (Spanning Tree Protocol) prevents network loops but is unrelated to power delivery. VLANs segment network traffic logically but do not provide power. PoE (IEEE 802.3af/at/bt) is the direct solution to the missing power outlet constraint.
