Question
Your customer has a main office that houses 450 employees and a call center that houses 120 employees. The main office and the call center are connected by a 100-megabits per second (Mbps) wide area network (WAN) link. The call center uses a Private Branch Exchange (PBX) that has 150 incoming lines. Your customer plans to deploy a Lync infrastructure for all employees. You collect network information and start building a Lync usage model. You need to identify the deliverables that must be achieved after the Lync usage modeling phase is completed. Which two deliverables should you achieve? (Each correct answer presents part of the solution. Choose two.)

Explanation
B (not C): The Microsoft Lync Server 2013, Planning Tool uses the following metric to estimate user traffic at each site and the number of ports that are required to support that traffic. / For Light traffic (one PSTN call per user per hour), figure 15 users per port. / For Medium traffic (2 PSTN calls per user per hour), figure 10 users per port. / For Heavy traffic (3 or more PSTN per user calls per hour), figure 5 users per port. E: In addition to the bandwidth required for the real-time transport protocol (RTP) traffic for audio and video media, bandwidth is required for real-time transport control protocol (RTCP). RTCP is used for reporting statistics and out-of-band control of the RTP stream.
