Question: 1
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. proposed location of the Lync Edge server
B. encryption protocols used to protect VPN communications
C. historic workload of the VPN appliance
D. codecs to be used by Lync clients
Answer: A AND D

Question: 2
Your customer’s network includes four offices and a data center that are connected by a Multiprotocol Label Switching (MPLS) network. Your customer has performed a network readiness assessment. The readiness report includes the following sections:
•Existing network topology
•Historical wide area network (WAN) links bandwidth utilization
•Bandwidth estimationso
Video bitrates per client window sizeso
Desktop sharing bitrateso
Bitrates per codec
•Users and locations You are asked to review the readiness report. You need to identify which sections are missing from the readiness report and should be included. Which two sections should you include? (Each correct answer presents part of the solution. Choose two.)
A. Modeling
B. Traffic Simulation
C. Discovery
D. Recommendations
Answer: B AND D

Question: 3
Your customer’s network includes three offices and two data centers that are connected by wide area network (WAN) links. Your customer has documented and modeled Lync usage within the current environment. You review the customer’s model and confirm that it is accurate. You need to recommend the next step in the Lync network readiness assessment. What should you recommend as the next step?
A. Perform traffic simulation.
B. Implement Quality of Service (QoS).
C. Calculate bandwidth estimations over the WAN links.
D. Calculate audio capacity for a public switched telephone network (PSTN).
Answer: A

Question: 4
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 PSTN channels provisioned
C. number of calls that use RTAudio Wideband
D. number of peer-to-peer (P2P) calls over the MPLS network
E. number of intersite calls through PSTN
Answer: B AND E

Question: 5
Your company corporate telephony environment is a combination of Lync 2013 and traditional Private Branch Exchange (PBX). The company has 3,500 users at three sites that use a Multiprotocol Label Switching (MPLS) topology. On average, the company has 3 percent of its users dialing in for conferences and 7 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. The company also plans to migrate from an existing content sharing platform. You need to generate a persona by using IP-based unified communication (UC) scenarios. Which three pieces of information should you collect when you are defining a persona for the existing communications? (Each correct answer presents part of the solution. Choose three.)
A. PSTN-to-PSTN sessions
B. peer-to-peer (P2P) sessions
C. voice codec used
D. conference sessions

Question: 6
You perform a network readiness assessment for Lync deployment.
The network includes a main office and 40 branch offices. The main office and 30 of the branch offices are located in North America and use a dedicated 20-megabits per second (Mbps) Multiprotocol Label Switching (MPLS) link. The remaining 10 branch offices are located in India and are connected to the main office by a virtual private network (VPN) site-to-site link. Each branch office includes 100 clients and two multipurpose servers.
Employees from the branch offices will use the Lync client for peer-to-peer audio communications with employees at the main office. You need to identify the number of offices required to test Lync readiness. What is the minimum number of offices you should include?
A. 2
B. 3
C. 40
D. 41
Answer: B
