Q123. 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.
Answer: D
