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.3
• B.41
• C.2
• D.40

You are analyzing the collected data about the current environment.
You need to identify the information that will be used to develop usage modeling to fulfill the business requirements.
Which three pieces of information should you choose? (Each correct answer presents part of the solution. Choose three.)

• A.average meeting size and duration
• B.results of traffic simul-ation
• C.number of users at each location
• D.number of public switched telephone network (PSTN) channels provisioned
• E.total minutes of video conferences used per month

You need to determine whether the poor quality of Lync calls is related to inadequate network bandwidth. What should you do?

• A.Disable Quality of Service (QoS) support on all network switches.
• B.Calculate the current volume of Lync traffic in Litware, and then confirm that volume of Lync traffic does not exceed 50 percent of wide area network (WAN) bandwidth.
• C.Calculate the current volume of Lync traffic in Contoso, and then confirm that the volume of Lync traffic does not exceed 25 percent of wide area network (WAN) bandwidth.
• D.Enable Jumbo Frames on all network switches.

You need to implement a traffic regulation mechanism to monitor and classify packets, both incoming and outgoing, with the ability to remark excess traffic.
What should you use?

• A.Call Admission Control (CAC)
• B.traffic shaping
• C.traffic policing
• D.a queuing technique
