You must plan for POE in an office environment. Which one of these devices is least likely to be a POE PSE?

A VoIP phone is least likely to be a POE PSE of the devices listed. POE stands for Power over Ethernet,

which is a technology that allows devices to receive both power and data over a single Ethernet

cable. A POE PSE stands for Power Sourcing Equipment, which is a device that provides power to

other devices over Ethernet. A POE PD stands for Powered Device, which is a device that receives

power from a PSE over Ethernet. A midspan multi-port injector, a switch, and a midspan injector are

examples of POE PSEs, as they can supply power to multiple devices over Ethernet cables. A VoIP

phone is an example of a POE PD, as it can receive power from a PSE over an Ethernet

cable. However, some VoIP phones can also act as POE PSEs for other devices, such as IP cameras or

wireless access points, but this is not very common. Reference: CWNA-109 Study Guide, Chapter 8:
