The customer plans to connect 40 Voice over IP (VoIP) phones and 8 security cameras to a
switch:
The VoIP phones are Class 2 devices and require a maximum of 4.5W (draw 5w)
The security cameras are Class 4 devices and require a maximum of 17W (draw 20W)
The network architect is proposing switch that supports PoE and PoE + and has a Poe Power
budget of 370W.
The architect proposes the usage from of power allocation. What are the advantages and
disadvantages of this proposal?

A.
It allows the switch to run at a lower temperature, saving power and cooling costs, but it
decreases the performance for the phones.

B.
It allows the switch to connect to the PoE and PoE+ devices on cheaper copper cable, but it
limits the distance between the devices.

C.
It allows the switch to connect to the PoE and PoE + devices at the same time, but the
customer must purchase a redundant power supply.

D.
It allows the switch to support the PoE requirements without a redundant power supply, but
power might be oversubscribed if conditions change.
