What are two advantages of deploying dual VLANs on an access layer switch that connects to an

IP phone? (Choose two.)

A.
This is the default state when an IP phone is connected to an unconfigured Cisco Catalyst
switch.

B.
Dual VLANs allow for the logical separation of data and voice traffic, which allows the network
to process these two traffic types individually.

C.
There are no advantages if a Cisco IP phone has a PC attached. Both the voice and data
services should be in the same VLAN.

D.
Implementing dual VLANs allows you to connect two devices that are in different VLANs to a
single switch port.

E.
It is typically used for IP phones that are not Cisco IP phones, IP softphones, or when Cisco IP
phones or other Cisco voice devices (such as the Cisco VG248 Analog Phone Gateway) do not
support PCs to be connected to them.
