QUESTION 82
Drag and Drop Question
You perform a network readiness assessment for Lync deployment.
The organization’s network includes a main office and four branch offices. Each branch office is connected to the main office by a site-to-site link- Depending on the geographic location of the branch office, the link uses either a dedicated Multiprotocol Label Switching (MPLS) link or a virtual private network (VPN) site-to-site link. Each branch office includes 100 clients and one multi-purpose server. Employees at the branch offices will use the Lync client for peer-to-peer (P2P) audio communication with employees at the main office.
You need to assign tasks for the assessment phases.
Which task should you assign to each assessment phase?
(To answer, drag the appropriate task or tasks to the correct phase or phases in the answer area. Each task 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.)

QUESTION 83
Northwind Traders has a Lync 2013 deployment. The company has outsourced the help desk to a third-party service provider that is located in New Delhi. The service provider has a 10-MB site-to-site virtual private network (VPN) connection to Northwind Traders.
The service provider uses a proxy server to route and monitor traffic to Northwind Traders. Both sites’ computers are on the 10.10.1.x/24 subnet. The proxy server’s Northwind Traders- facing IP is 192.168.1.100.
New Delhi users can access Northwind Traders’ Lync environment with [email protected], and they are able to access conferences without issue. However, users complain that they are unable to share their desktops.
You need to recommend a solution.
Which two actions should you recommend? (Each correct answer presents a complete solution. Choose two.)

A.    Add an Edge server at the New Delhi office.
B.    Route Lync traffic externally by using the Edge server.
C.    Disable all firewalls between Northwind Traders and New Delhi.
D.    Change IP scope and remove the proxy server.

Answer: AB
Explanation:
The Edge Server provides users with the same external characteristics and internal experience that Lync Server 2013..
With the publication of the Edge Server, the following features are supported:
/Connecting remote clients;
/Federation with messenger;
/Integration with Public IM’s;

QUESTION 84
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.    conference sessions
B.    voice codec used
C.    PSTN-to-PSTN sessions
D.    peer-to-peer (P2P) sessions
E.    content sharing

Answer: ABC

QUESTION 85
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.    codecs to be used by Lync clients
B.    encryption protocols used to protect VPN communications
C.    proposed location of the Lync Edge server
D.    historic workload of the VPN appliance

Answer: AD
Explanation:
Note:
* Bandwidth figures include the protocol overheads for IP, UDP, RTP, and SRTP. This is why the Microsoft bandwidth figures for standard codecs are different from those quoted by other VoIP suppliers, who only state the raw codec figure, and not the entire packet overhead.

QUESTION 86
Drag and Drop Question
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.)

Answer:

 

QUESTION 87
You prepare Co deliver a network assessment for a customer. The customer has four sites as described in the following table:

The results of the traffic simu-lation between New Delhi and New York are shown in the following table:

You need to analyze the data and provide the General Comments for the traffic simu-lation results. What should you recommend?

A.    The network performance is less than acceptable.
Average Jitter is outside of recommended levels.
