Microsoft Network Readiness and Assessment for Lync Sample Questions:

1. Your corporate telephony environment is a combination of Lync 2013 and traditional Private Branch Exchange (PBX). Currently, the company has 2,000 users. The company expects to add an additional 2,000 users during the next year. On average, the company has 20 percent of its users on a public switched telephone network (PSTN) call at any time. Currently, users make three or more PSTN calls per hour, and it is expected that the new users will make a similar number of calls.
The circuit count for light, medium, and heavy traffic is shown in the table below:

You need to recommend the number of ports required by the PBXs for simulated current usage and the expected growth. How many ports should you recommend?

A) 160
B) 80
C) 40
D) 54

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

3. Your customer has a main office that houses 450 employees and a call center that houses 120 employees. The main office and the call center are connected by a 100-megabits per second (Mbps) wide area network (WAN) link. The call center uses a Private Branch Exchange (PBX) that has 150 incoming lines.
Your customer plans to deploy a Lync infrastructure for all employees.
You collect network information and start building a Lync usage model.
You need to identify the deliverables that must be achieved after the Lync usage modeling phase is completed.
Which two deliverables should you achieve? (Each correct answer presents part of the solution. Choose two.)

A) calculation of server-to-server generated Lync traffic
B) calculation of user-generated Lync traffic
C) RTC traffic estimation over the WAN link
D) Quality of Service (QoS) configuration
E) calls simu-lation over the WAN link

4. You perform a network readiness assessment for Lync deployment for a customer's organization.
The customer's organization includes five sites that are connected by site-to-site virtual private network (VPN) links. Each site includes 20 to 100 client computers.
You want to prepare a Lync traffic simul-ation.
You need to select the network traffic characteristics to collect.
Which three network traffic characteristics should you select? (Each correct answer presents part of the solution. Choose three.)

A) one-way network delay
B) average jitter
C) TCP/IP port statistics
D) peer-to-peer (P2P) available bandwidth
E) average packet loss
F) minimum jitter

5. HOTSPOT
You need to identify the wide area network (WAN) link between the Detroit office and the data center that shows unacceptable performance. Which link on the network topology diagram should you choose? (To answer, select the appropriate link in the answer area.)
