You perform a network readiness assessment for Lync deployment for a customer’s organization. The customer’s organization includes five sites that are connected by site-to-site virtual private network (VPN) links. Each site includes 20 to 100 client computers.
You want to prepare a Lync traffic simul-ation.
You need to select the network traffic characteristics to collect. Which three network traffic characteristics should you select? (Each correct answer presents part of the solution. Choose three.)
A. TCP/IP port statistics
B. average packet loss
C. one-way network delay
D. minimum jitter
E. average jitter
F. peer-to-peer (P2P) available bandwidth
Correct Answer: BCE
Explanation/Reference:
Your simul-ation testing should use five baseline network characteristics that will quantify your network’s performance under the anticipated traffic volume that your users will generate by using Lync Server.
A simul-ation tool must be able to generate traffic (real RTP/RTCP traffic), collect, and then graph the variation in the five baseline network characteristics for each call:
. One-way network delay (C)
. Average jitter(E)
. Maximum jitter
. Average packet loss (B)
. Burst packet loss (peak consecutive packets lost)
