NEW QUESTION 3

Your company’s corporate telephone environment is a combination of Skype for Business Server 2015 and traditional Private Branch Exchange (PBX). The sites are connected by a Multiprotocol Label Switching (MPLS) topology. There are 6,500 users enabled for Skype for Business Server 2015 video conferencing. You use the RTVideo and H.264 codecs for video conferencing. On average, 12 percent of users are on a video conference at any one time. The company plans to add additional bandwidth for all sites.
