Q1. 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.

Q6. Which of the following should the Enterprise Campus network designer consider with respect to Video traffic? 

A. While it is expected that the sum of all forms of video traffic will grow to over 90% by 2013, the Enterprise will be spared this rapid adoption of video by consumers through a traditional top-down approach 

B. Avoid bandwidth starvation due to video traffic by preventing and controlling the wide adoption of unsupported video applications 

C. Which traffic model is in use, the flow direction for the traffic streams between the application components, and the traffic trends for each video application 

D. Streaming video applications are sensitive to delay while interactive video applications, using TCP as the underlying transport, are fairly tolerant of delay and jitter
