Your company's corporate telephony environment is a combination of Lync 2013 and traditional Private Branch Exchange (PBX). The sites are connected by a Multiprotocol Label Switching (MPLS) topology. There are 6,500 users enabled for Lync 2013 video conferencing. Only RTVideo is being used 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.
The company is concerned about the quality of video conferences.
As part of a bandwidth upgrade process, you model real-time transport protocol (RTP) media call flows for video communications that use only RTVideo. You have determined the average number of video conferences and estimated the bandwidth required for the video portion.
You need to identify the additional bandwidth requirements when modeling real-time transport control protocol (RTCP).
Which bandwidth option should you choose?

• A.10 kilobits per second (kbps) total
• B.10 kilobits per second (kbps) per stream
• C.30 kilobits per second (kbps) total
• D.15 kilobits per second (kbps) per stream

Woodgrove Bank plans to implement Lync 2013 for all voice and video enterprise communications.
The bank's network topology is shown in the exhibit. (Click the Exhibit button.)

The bank wants to design a Lync Server traffic simu-lation before the production implementation.
You need to determine the locations to test the Lync Server traffic simu-lation.
Which locations should you test?

• A.Main office in Boston Data center in New York All sites that have connectivity issues
• B.Main office in Boston Data centers in New York, Prague, and Beijing Ten branches in North America Five branches in Europe Ten branches in Asia
• C.Main office in Boston Data centers in New York, Prague, and Beijing One branch in North America One branch in Europe One branch in Asia
• D.Main office in Boston Data centers in New York, Prague, and Beijing Two branches in North America One branch in Europe Three branches in Asia

You need to collect relevant information about the existing video conferencing solution.
Which piece of information should you collect?

• A.base video resolution used by the third-party video conferencing solution
• B.conferencing usage statistics
• C.echo cancellation capabilities with third-party video appliances
• D.video codecs used by the third-party video conferencing solution

Your customer's network includes two offices that are connected by a 100-megabits per second (Mbps) wide area network (WAN) link. Each office has 200 employees. Most employees work remotely and connect to the internal network by using a virtual private network (VPN).
Your customer plans to deploy Lync to support peer-to-peer (P2P) and conference sessions between employees. The customer wants to minimize Lync workload at the existing VPN server appliance.
You prepare modeling of Lync traffic for the customer's network.
You need to determine what additional information should be collected and included in the modeling calculation.
Which two pieces of information should you collect? (Each correct answer presents a complete solution. Choose two.)

• A.historic workload of the VPN appliance
• B.codecs to be used by Lync clients
• C.proposed location of the Lync Edge server
• D.encryption protocols used to protect VPN communications

DRAG DROP
You need to analyze the bandwidth impact of different video call flows at the Beijing office.
Which codec will apply to which call flow? (To answer, drag the appropriate codec or codecs to the correct call scenario or scenarios in the answer area. Each codec may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Correct Answer:
