A network administrator is considering whether PoE features are required in a specific network installation. Which option provides valid information about PoE?
- The PoE pass-through feature is only supported by the Cisco Catalyst 3560-C Series compact switch model or higher.
- Any switch port can be configured with IOS commands to function as a PoE port.
- PoE allows the switch to deliver power to a device over the existing power grid.
- It can be used by IP phones, allowing them to be installed anywhere that there is an Ethernet cable.
Explanation: The Power over Ethernet (PoE) feature allows the switch to deliver power to a device over the existing Ethernet cabling. This feature can be used by IP phones and some wireless access points, allowing them to be installed anywhere that there is an Ethernet cable. The Cisco Catalyst 2960-C and 3560-C Series compact switches support the PoE pass-through feature. It allows a network administrator to power PoE devices connected to the switch, as well as the switch itself, by drawing power from certain upstream switches.
