Your company corporate telephony environment is a combination of Lync 2013 and traditional Private Branch Exchange (PBX). The company has three sites that are connected by a Multiprotocol Label Switching (MPLS) topology. There are 1,250 users who are using Lync 2013 and 2,250 users who are using the PBX environment. On average, the company has 3 percent of its users dialing in for conferences and 6 percent on a public switched telephone network (PSTN) call at any time.
The company plans to remove the PBXs and have all users use only Lync 2013.
You need to generate a usage model based on the existing data usage and real-time communications through all of the PBXs.
Which two pieces of information should you collect when you performing usage modeling? (Each correct answer presents part of the solution. Choose two.)

• A.number of calls that use G.722
• B.number of peer-to-peer (P2P) calls over the MPLS network
• C.number of intersite calls through PSTN
• D.number of PSTN channels provisioned
• E.number of calls that use RTAudio Wideband

HOTSPOT
How should you set the modalities in the Lync Bandwidth Calculator? (To answer, select the appropriate value in each drop-down menu in the Lync Bandwidth Calculator.)

正解：

You need to ensure that wireless users in the main office stay associated with the most powerful wireless access point (WAP) available when they are roaming.
What should you do?

• A.Configure all WAPs on the same channel.
• B.Configure fast roaming.

HOTSPOT
Your customer's network includes a main office with 500 employees and 10 branch offices with 200 employees each. All branch offices are connected to the main office by wide area network (WAN) links.
You analyze the network readiness for Lync deployment. The customer estimates that at any given time, 20 employees at each branch office will be involved in audio conferences and 150 will be involved in public switched telephone network (PSTN) conversations over the WAN link.
You need to modify the relevant modalities of the correct usage model for the branch offices.
How should you modify the relevant modalities? (To answer, select the appropriate value in each drop-down menu in the table showing information from the Lync Persona tab.)

正解：

You need to recommend changes to improve the quality of Lync calls for users in the Detroit and Chicago offices. Which change should you recommend?

• A.Upgrade the wide area network (WAN) links at these offices to 30 megabits per second (Mbps).
• B.Implement Quality of Service (QoS).
• C.Upgrade the data center's Multiprotocol Label Switching (MPLS) link to 1,100 megabits per second (Mbps).
• D.Connect the offices to the Multiprotocol Label Switching (MPLS) network from Provider 1.
