When planning an access point deployment that utilizes Power over Ethernet (PoE) switches at
the network edge, what design decision could adversely affect the operation of 802.3af APs?

A.
All ports on the Ethernet switch will be supporting Class 3 PoE powered devices.

B.
Some APs are connected to a PoE switch and are also receiving power from an AC outlet.

C.
The Ethernet switch’s uplink ports are not connected to an 802.3af-compliant core or
distribution Ethernet switch.

D.
A gigabit Ethernet switch port supporting an 802.11a/g AP auto-negotiates to 100 Mbps.

E.
The installation team is not informed that PoE support will reduce the recommended maximum
UTP cabling length from 100m to 50m.
