Topic 1, Humongous Insurance
Background
Humongous Insurance currently employs 7,500 people and is based in the United States.
The company has 4,000 users in its main office in Chicago. It also has two branch offices, one in
New York with 2,000 users and the other in Los Angeles with 1,500 users. The company has 30
executives located across the offices.
The company recently migrated from Lync Server 2010 to Lync Server 2013.
The company plans to increase the use of audio and video (A/V) conferencing to reduce travel
costs. Employees have been asked to use A/V, telephony, and instant messaging (IM)
conferencing solutions whenever possible for communication with clients and users in the branch
offices.
Humongous Insurance is federated with Trey Research Corporation, which uses a third-party IM.
Users at both companies need to communicate with each other by using their respective IM
client.
The company plans to continuously analyze the network to identify:
potential network delay points and
availability of adequate bandwidth to meet current requirements and anticipated
growth. The company plans to continuously analyze the Lync 2013 servers for performance metrics.
Planned Changes
Humongous is in discussion to acquire the Southridge Video company. Southridge Video has
2,000 users in two sites.
Employees of Humongous Insurance use a variety of mobile devices, including Windows Phones
and iOS phones. All iOS phone users must be notified of events, such as new or missed IM
invitations and voice mail messages, even when they are using the corporate wireless network.
All public switched telephone network (PSTN) traffic will use the G.711 codec.
All voice will use the RTAudio Wideband codec.
All peer-to-peer (P2P) video sessions will support H.264 and RTVideo codecs.
Audio bandwidth between the Los Angeles and New York offices is limited.
Challenges
All users report poor audio and video quality. Calls are dropped or suffer from jitter and lag.
These issues exist when users are using the Lync client or Lync Phone Edition.
Humongous Insurance users currently are unable to IM with external clients that use different IM
programs.
Currently there is no network oversight for Lync communications.
The company has no plans to increase the bandwidth at any sites.
Humongous Insurance does not have a defined remote user access policy.
Existing Environment

The concurrent communication modalities usage of the three offices is shown in the following
table:
Humongous Insurance expects to see the number of video users increase by as much as 10
percent. The company expects to see the number of voice users increase by as much as 15
percent.
All users at Humongous Insurance will be Lync enabled.
The company uses synthetic transactions to perform call and voice tests.
Many of the employees of Humongous Insurance work from home and sign in securely to the
corporate environment in order to use Lync.
Business Requirements
Humongous Insurance would like to review the existing network topology and wants to ensure that network capacity will meet current Lync 2013 infrastructure capacity requirements for audio and video usage, as well as meet the anticipated increases. All existing issues relating to the poor quality of Lync calls and conferencing need to be addressed. Company policy allows for all employees to have the option to use video conferencing. Employees will be limited to VGA video quality. Company executives will not have these
limitations.
Quality of Service (QoS) ports must be unique for audio and video traffic.
The company wants to confirm that the current network bandwidth allocated for the network is
sufficient for all current and anticipated growth in Lync traffic and would like to guarantee highquality
Lync calls and video conferencing.
Humongous Insurance wants to ensure that the volume of Lync traffic does not exceed 50
percent of WAN bandwidth.
The recommended design solution needs to eliminate the possibility of WAN oversubscription
by Lync traffic.
Humongous Insurance wants to use only dedicated computers to monitor the network and
perform synthetic transactions to limit the load on the computers.
The proposed Lync 2013 solution needs to provide scalability to accommodate the company’s
future acquisition of Trey Research.
The proposed Lync 2013 solution should be readily available for users in all three sites.
Technical Requirements
The company wants to allow only authorized employees to connect remotely.
All remote users will use a secure method when remotely connecting to the network and the
Lync environment.
The number of open and listening ports must be kept to a minimum.
All maintenance and tests of network policies must be done outside of normal business hours.
Bandwidth between sites cannot be increased.
The quality of voice and video traffic must be increased.
The number of dropped calls must be reduced.
The corporate information technology (IT) department must be able to push updates and scan
users’ computers when they are connected remotely.
All push notifications must be able to be sent mobile clients on all supported cell phone
manufactures. Many users do not use Windows mobile phones.
IM users must be able to IM with users who are using other IM programs.
The Microsoft Lync 2013 Bandwidth Calculator must be used to analyze Lync traffic.
It is recommended to deploy QoS for end-to-end support.

QUESTION 4
You need to configure the monitoring computers to support the deployment of watcher nodes to meet the technical requirements. What should you do?
A. Deploy the Lync 2013 watcher nodes on the same computers as the Lync 2010 watcher nodes.
B. Deploy Lync 2013 watcher nodes and remove the Lync 2010 watcher nodes.
C. Run the Install-CsWatcherCollocate cmdlet on each computer that is running the Lync 2010 watcher nodes.
D. Run the Install-CsLegacyWatcherNode cmdlet on each computer that is running the Lync 2010 watcher nodes.
Correct Answer: B Explanation
Explanation/Reference:
A legacy Microsoft Lync Server 2010 watcher node cannot be collocated on the same machine with a Lync Server 2013 watcher node. This is because the core
system files for Lync Server 2010 and Lync Server 2013 cannot be installed on the same computer.
However, Lync Server 2013 watcher nodes can simultaneously monitor both Lync Server 2013 and Lync Server 2010. The Default synthetic transactions are
supported on both product versions.
QUESTION 5

D. Ensure that VoiceDiffservtag values are set to 46 for all Lync Phone Edition devices at all sites.
Correct Answer: D Explanation
Explanation/Reference:
Explanation: We have QoS on the servers using a DSCP value of 46 for audio. We should configure the Lync Phone devices to use the same DSCP value (instead of the default 40).
QUESTION 6
You need to recommend a solution to meet the planned changes for remote users. Which two actions should you recommend? (Each correct answer presents
part of the solution.
Choose two.)
A. Configure internal Domain Name System (DNS) to point to the external IPv4 address for Lync Edge Services.
B. Configure Direct Access on CHI-Edge1.
C. Configure Direct Access to send Domain Name System (DNS) queries for the access, webconf, av, _sip._tls, and meeting URLs and all other Lync services to external DNS.
D. Limit service to selected IP addresses in the Topology Builder.
Correct Answer: BC Explanation Explanation/Reference:
DirectAccess, Its Microsoft new Remote connectivity solution where users on the Internet get Intranet connectivity to their corporate network without installing any client or initiating any software like old traditional VPN. Microsoft DirectAccess is purely based on IPV6 and Lync 2013 is fully supporting IPV6 and Lync 2013 clients using DirectAccess should work without any problem. If any one encountered problems making Lync calls or connecting to Lync on a DirectAccess Computer then you need to ensure that IPV6 is enabled on the Lync 2013 Server as per the below image.
This can be achieved as follows:
Open the Lync 2013 Topology Builder from an old file or download the topology 1.
Edit the properties of the Lync server and in the General Properties ensure that IPV6 2.
is enabled.
These settings need to be published from the Action Menu – Topology – Publish 3.
Now you can enjoy Lync 2013 over DirectAccess Connection.
* From scenario:
The company wants to allow only authorized employees to connect remotely. All remote users will use a secure method when remotely connecting to the network
and the Lync environment.
QUESTION 7
You need to identify the current maximum bandwidth required for peer-to-peer (P2P) video calls to match business requirements. Which bandwidth should you choose?
A. 303,750 Kbps
B. 310,960 Kbps
C. 759,760 Kbps
D. 1,503,750 Kbps
Correct Answer: A Explanation
Explanation/Reference:
The company has 30 executives located across the offices. Company policy allows for all employees to have the option to use video conferencing. Employees will be limited to VGA video quality. Company executives will not have these limitations.
All peer-to-peer (P2P) video sessions will support H.264 and RTVideo codecs
VGA = 640×480 = 800kpbs for H.264 and RTVideo. Execs using H.264 and RTVideo = 2500kbps
5% of 7500 users = 375 5% of 30 execs = 1.5
(375 x 800) + (1.5 x 2500) = 303,750
QUESTION 8
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.
Correct Answer: AC Explanation
Explanation/Reference:
Mobile device clients do not support multiple Secure Sockets Layer (SSL) certificates from different domains. Therefore, CNAME redirection to different domains is not supported over HTTPS. For example, a DNS CNAME record for lyncdiscover.contoso.com that redirects to an address of director.contoso.net is not supported over HTTPS. In such a topology, a mobile device client needs to use HTTP for the first request, so that the CNAME redirection is resolved over HTTP. Subsequent requests then use HTTPS. To support this scenario, you need to configure your reverse proxy with a web publishing rule for port 80 (HTTP).
If you support push notifications and want Apple mobile devices to receive push notifications over your Wi-Fi network, you also need to open port 5223 on your enterprise Wi-Fi network. Port 5223 is an outbound TCP port used by the Apple Push Notification Service (APNS).
From scenario: All push notifications must be able to be sent mobile clients on all supported cell phone manufactures. Many users do not use Windows mobile phones.

QUESTION 9
You need to deploy and enable Quality of Service (QoS) on all workstations to meet the planned changes and performance goals. Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)
A. Apply Service Pack 3 to all Windows XP workstations and Service Pack 2 to all Windows Vista workstations.
B. Create Group Policy objects (GPOs) for Lync audio and video and configure them to use the same port ranges and Differentiated Services Code Point (DSCP) values for QoS.
C. Create Group Policy objects (GPOs) for Lync audio and video and configure them to use different port ranges and Differentiated Services Code Point (DSCP) values for QoS.
D. Configure the Group Policy object (GPO) configuring QoS and set it to Enforced.
E. Upgrade all Windows XP and Windows Vista workstations to Windows 7 or above.
Correct Answer: CDE Explanation
Explanation/Reference:
Note that Microsoft Lync Server 2013 does not support QoS for other Windows operating systems, such as Windows Vista or Windows XP.
The port ranges and DSCPs must be different for audio and video. To create a Quality of Service audio policy for Windows 7 or Windows 8 computers, first log on to a computer where Group Policy Management has been installed. Open Group Policy Management (click Start, point to Administrative Tools, and then click Group Policy Management) and then complete the following procedure:
1.
In Group Policy Management, locate the container where the new policy should be created. For example, if all your client computers are located in an OU
named Clients then the new policy should be created in the Client OU.
2.
Right-click the appropriate container and then click Create a GPO in this domain, and Link it here.
3.
In the New GPO dialog box, type a name for the new Group Policy object in the Name box (for example, Lync Audio) and then click OK.
4.
Right-click the newly-created policy and then click Edit.
5.
In the Group Policy Management Editor, expand Computer Configuration, expand Policies, expand Windows Settings, right-click Policy-based QoS, and then
click Create new policy.
6.
In the Policy-based QoS dialog box, on the opening page, type a name for the new policy (e.g., Lync Audio) in the Name box. Select Specify DSCP Value and
set the value to 46. Leave Specify Outbound Throttle Rate unselected, and then click Next.
7.
On the next page, make sure that All applications is selected and then click Next. This setting instructs the network to look for all packets with a DSCP marking
of 46, not just packets created by a specific application.
Etc.
QUESTION 10
You need to identify the current average amount of bandwidth required for peer-to-peer (P2P) voice calls for all three sites. Which bandwidth should you choose?
A. 36,960 Kbps
B. 51,150 Kbps
C. 80,025 Kbps
D. 135,795 Kbps
Correct Answer: B Explanation

Topic 2, A Datum Corporation
Background
Based in North America, A. Datum Corporation is a leading financial technology solutions provider. The company provides mortgage lending processing, payment solutions, call centers, and other services for the largest Canadian and US financial institutions.
A. Datum Corporation has its main office and a data center in Toronto. Call centers are located in Montreal and Quebec. Branch offices are located in other cities across Canada and the United States. The company plans to consolidate multiple isolated voice communication systems used across the office sites by a single scalable and secured unified communications (UC) solution. The company evaluated several UC vendors and has decided to deploy Microsoft Lync 2013.
A. Datum Corporation has grown very fast within the last few years. The company has made multiple acquisitions. Each acquired company had its own information technology (IT) policies and support procedures, and some branch offices still operate relatively independently. As a result, the existing network and server infrastructure is very inconsistent.
Existing Environment
A. Datum Corporation has consolidated all production servers in the data center. Network
switches and routers are mounted in the data center and in secured racks in the offices.
Audio conferencing services for all employees are provided by a dial-in conferencing provider.
Video conferencing services are available in designated meeting rooms at various offices and are
based on an eight-year-old third-party solution.
All offices, except the call centers, are linked by a Multiprotocol Label Switching (MPLS)
network. The call centers are connected with the data center by virtual private network (VPN)
links.
Quality of Service (QoS) is not currently implemented, but network specialists have detected that
all existing equipment is compatible with possible QoS implementation.
The network topology diagram is shown in the Network Topology Diagram exhibit- (Click the
Exhibit button.) The diagram shows bandwidth capacity of primary wide area network (WAN)
links. All offices also have backup WAN links with bandwidth capacity of 50 percent of the
Call center statistics show a steady increase in average call duration. Fifteen percent of call center incoming public switched telephone network (PSTN) calls are transferred to employees located in other offices.
Business Requirements
A. Datum Corporation wants to evaluate the existing network infrastructure to ensure that the
infrastructure is capable of meeting the company’s expectations of the new UC solution.
All existing phones will be replaced with voice over Internet protocol (VoIP) Power over
Ethernet (PoE) phones.
Employees who travel between offices or work remotely must be able to use the Lync 2013
client installed on their laptops to make phone calls.
The proposed Lync deployment and possible QoS policies should not increase existing average
network traffic delays for existing applications.
Audio conferencing traffic for employees in the call center sites must be limited.
The call centers must support monthly workload fluctuations from 50 to 200 contract employees
who serve customers’ incoming PSTN calls.
Audio communication between the offices must be operational 24 hours a day, seven days a
week. Audio communication must remain available in a case of an external power failure at any
office or at the data center.
The company also plans to improve the quality of call center services by decreasing the rate of
dropped calls due to busy PSTN lines.
The network must be able to automatically switch to backup WAN links without any degradation
of audio call quality.
Technical Requirements
All communications within the UC infrastructure must be secure due to compliance requirements
for processing credit card information.
Wireless networks are restricted in the call centers; however, several other offices have
implemented wireless guest networks.
Lync Edge Servers and Conference Servers will be located in the data center.
Existing analog and digital Private Branch Exchanges (PBXs) will be replaced with Lync
Mediation Servers. The existing video conferencing solution will remain untouched and left
without Lync integration.
The network infrastructure must provide maximum network latency for real-time communication
(RTC) traffic of 150 ms between any two offices.
Available bandwidth for the Lync RTC traffic is limited to 20 percent of the primary WAN links
bandwidth.
Lync Traffic simul-ation
The initial Lync traffic simul-ation has been completed for the following locations:
Boston
Detroit
Chicago
Montreal
Quebec
Toronto data center
A.
Datum Corporation wants to design and perform an additional Lync traffic simul-ation for all other offices. The additional simul-ation must also include external users that connect through the Edge Server and simulate phone calls to the Mediation Server. An output of the tracert.exe tool running from a desktop computer in the Quebec call center was captured during the initial Lync traffic simul-ation. The output is shown in the Quebec Traffic simul-ation Output exhibit. (Click the Exhibit button.)
An output of the pathping.exe tool running on a computer located in the Montreal call center was captured during the initial Lync traffic simul-ation. The target computer is located in the data center. The output is shown in the Montreal Traffic simul-ation Output exhibit. (Click the Exhibit button.)
