Microsoft Network Readiness and Assessment for Lync Sample Questions:
1. You analyze Lytic traffic modeling for a customer's network. The network includes a main office, a data center, and five branch offices. Lync servers are consolidated in the data center. The main office and the data center are connected to a Multiprotocol Label Switching (MPLS) network. The branch offices are connected to the main office with virtual private network (VPN) links. The model uses all Lync modalities for all users. The network topology diagram is shown in the exhibit. (Click the Exhibit button.)
The model indicates that the main office exceeds the bandwidth available for Lync over the MPLS link by 10 percent. The utilization of VPN links available for Lync traffic is at almost 100 percent.
You need to recommend a change to optimize Lync traffic through the main office MPLS link.
What should you recommend?
A) Deploy a Survivable Branch Appliance (SBA) at all branches.
B) Move the Lync pool to a branch office.
C) Deploy a Survivable Branch Appliance (SBA) at the main office.
D) Move the Lync pool to the main office.
2. 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) 54
B) 80
C) 160
D) 40
3. DRAG DROP
You prepare a Lync traffic model for a customer's network by using the Lync Bandwidth Calculator. A high-level network topology is shown in the exhibit. (Click the Exhibit button.)
You need to define sites on the Sites worksheet of the Bandwidth Calculator.
Which table should you use for each office? (To answer, drag the appropriate office or offices to the correct table or tables in the answer area. Each office 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.)
4. 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.)
5. You need to configure the Lync 2013 environment to meet the technical requirements for
push notifications for mobile users. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A) Configure a web publishing rule for port 80 on the reverse proxy for the acquired domain.
B) Configure CNAME redirection over HTTPS for the acquired domain.
C) open port 5223 on the Enterprise Wi-Fi network.
D) Open port 23457 on the Enterprise Wi-Fi network.
