NO.1 Your company corporate telephony environment is a combination of Lync 2013 and traditional
Private Branch Exchange (PBX). The sites are connected by a Multiprotocol Label Switching (MPLS)
topology. There are 750 users who are using Lync 2013 and 2,500 users who are using the PBX
environment. On average, the company has 10 percent of its users in conferences. The company
plans to add additional bandwidth for all sites.
The company is concerned about the number of dropped calls on the PBXs.
As part of a bandwidth upgrade process, you model real-time transport protocol (RTP) media call
flows for audio communications. You have determined the average number of calls and estimated
the bandwidth required for the audio portion of the calls.
You need to identify the additional bandwidth requirements when modeling real-time transport
control protocol (RTCP) traffic.
Which bandwidth option should you choose?
A. 5 kilobits per second (kbps) per stream
B. 5 kilobits per second (kbps) total
C. 20 kilobits per second (kbps) total
D. 20 kilobits per second (kbps) per stream
Answer: A

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.
A third party IM provider will use XMPP.
NO.3 You need to determine whether the poor quality of Lync calls is related to inadequate network
bandwidth. What should you do?
A. 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.
B. Disable Quality of Service (QoS) support on all network switches.
C. 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.
D. Enable Jumbo Frames on all network switches.

NO.4 DRAG DROP
You prepare a response to a client's request for proposal (RFP) for a Lync network readiness
assessment.
The client's network includes a main office that houses 500 employees and 30 branch offices that
house 20 to 100 employees each. All sites are connected by a Multiprotocol Label Switching (MPLS)
network. The client plans to use Lync video and upload and share Microsoft PowerPoint
presentations.
The client wants to perform a Lync network assessment.
You need to include the required tasks in the RFP response, in the correct order.
Which four tasks should you perform in sequence? (To answer, move the appropriate four actions
from the list of actions to the answer area and arrange them in the correct order.)
Answer:
NO.5 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. 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.
B. 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.
C. Upgrade all Windows XP and Windows Vista workstations to Windows 7 or above.
D. Apply Service Pack 3 to all Windows XP workstations and Service Pack 2 to all Windows Vista
workstations.
E. Configure the Group Policy object (GPO) configuring QoS and set it to Enforced.
Answer: B,C,E
74-335 Questions and answers 74-335 Practice Questions
Explanation:
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:
- 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.
- Right-click the appropriate container and then click Create a GPO in this domain, and Link it here. - I
n 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. - Right-click the newly-created policy and then click Edit. - I
n the Group Policy Management Editor, expand Computer Configuration, expand Policies, expand
Windows Settings, right-click Policy-based QoS, and then click Create new policy.
- 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.
- 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.
NO.6 DRAG DROP
You analyze the results of Lync traffic modeling for a customer's network. Information about the
network is displayed in the exhibit. (Click the Exhibit button.)
The model is based on all Lync modalities usage and assumes that all Lync servers are consolidated in
the datacenter.
Your customer wants to dedicate no more than 30 percent of its Multiprotocol Label Switching
(MPLS) links to Lync traffic. The branch office link must accommodate at least 50 simultaneous phone
calls.
You need to recommend network changes to meet the customer's requirements.
Which change should you recommend for each link? (To answer, drag the appropriate change or
changes to the correct link or links in the answer area. Each change 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:
NO.7 HOTSPOT
You analyze the results of Lync traffic modeling for a customer's network. The relevant portion of the
network topology diagram is shown in the answer area.
The estimated links workload is shown in the following table:
The customer wants to build a highly available Lync infrastructure.
You need to determine which link must be updated to support the customer's requirements.
Which link should you update? (To answer, select the appropriate link in the network
topology diagram.)
Answer:
NO.8 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. Run the Install-CsWatcherCollocate cmdlet on each computer that is running the Lync 2010
watcher nodes.
C. Run the Install-CsLegacyWatcherNode cmdlet on each computer that is running the Lync 2010
watcher nodes.
D. Deploy Lync 2013 watcher nodes and remove the Lync 2010 watcher nodes.
Answer: D
74-335 pdf
Explanation:
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.
