Which of the following facts must be considered when designing for IP telephony within an
Enterprise Campus network?
A.
Because the IP phone is a three-port switch, IP telephony extends the network edge, impacting
the Distribution layer.
B.
Video and voice are alike in being bursty and bandwidth intensive, and thus impose
requirements to be lossless, and have minimized delay and jitter.
C.
IP phones have no voice and data VLAN separation, so security policies must be based on
upper layer traffic characteristics.
D.
Though multi-VLAN access ports are set to dot1q and carry more than two VLANs they are not
trunk ports.
D
The concept of an access port has been extended to a multi-VLAN access port in the
enterprise campus.
Multiservice switches support a new parameter for IP telephony support that makes the
access port a multi-VLAN access port. The new parameter is called an auxiliary VLAN.
