configuration for Back End Servers named Backend 1 and Backend2. You execute the GetCSDatabaseMirrorState cmdlet and discover the following errors.

You need to resolve the connectivity issue and bring up the mirror databases to the synchronized
state between the Back End Servers. What should you do?

• one Back End Server named Lync2013BE
You plan to install a single Edge Server. You create an Edge pool named Lync2013Edge.contoso.local.
You want to configure the following Edge services:
• Access Edge to use sip.fabrikam.com
• Web Conferencing to use conf.fabrikam.com
You also want to enable the federated access feature.
You need to assign internal and external certificates to the Lync 2013 Edge server.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose
two.)

You support a customer whose network environment includes Microsoft Lync Server 2013 Standard

should you do?

DRAG DROP
You support a Microsoft Lync Server 2013 environment for a customer named Litware, Inc. The
worldwide network includes the following:
• 15,000 Enterprise Voice enabled users
• three Front End pools with three Front End Servers in each pool
• three Edge Server pools with two Edge Servers in each pool
• two Group Chat pools with two Group Chat Servers in each pool

• 20 Survivable Branch Appliances (SBAs) deployed at various offices
Of the 15,000 users, 6,000 have Polycom CX600 phones on their desks. Each pool has redundant
session initiation protocol (SIP) trunk settings with a local SIP trunk provider at its respective pool. An
executive assistant receives a call from a customer. He puts the call on hold and calls the executive.
After he talks to the executive, he transfers the call to the executive. The executive assistant reports
that the call fails to transfer, and that he gets the call back. This results in him taking a message.
Based on this user report, you perform the following actions:
1. Start the ClsController.exe with only one Front End pool selection.
2. Make a call from your mobile phone to a CX600 desk phone named DeskPhone1.
3. Answer the incoming call by using DeskPhone1 and put the call on hold.
4. From DeskPhone1, dial the number of a second CX600 phone named DeskPhone2.
5. Answer the incoming call by using DeskPhone2.
6. From DeskPhone1, transfer the call that you have on hold.
After you attempt to transfer the call from DeskPhone1 to DeskPhone2, you observe that the call
failed to transfer and returned back to DeskPhone1. You generate a Lync.log file. You need to
identify the problem by using the quick search capabilities of the Snooper tool. Which action should
you perform for each troubleshooting activity? (To answer, drag the appropriate action to the
correct troubleshooting activity or activities. Each action 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.)

You plan to deploy a Microsoft Lync Server 2013 Enterprise server by using a side-by-side upgrade
from Office Communication Server (OCS) 2007 R2.
You perform the following actions:
• Complete the schema updates, forest update, and domain update.
• Define and connect the Lync Server 2013 topology to OCS 2007 R2 by using topology builder.
• Deploy Front End Pool, Director Pool, Persistent Chat Pool, and Edge Pool.
The Lync Server 2013 environment is using the OCS 2007 R2 Mediation Server and associated PSTN
gateway for PSTN inbound and outbound calls.
You want to test the Lync Server 2013 server for inbound, outbound, and dial-in conference calls
from a test computer that is located in a customer’s office. Your access to the customer network is
restricted to Lync Severs, OCS servers, and some test computers.
During inbound, outbound, and dial-in conference calls, you encounter problems with media. The
calls have significant jitter and packet loss. Calls are intermittently disconnecting. You need to
determine the cause of these problems. What should you do?

You support a customer whose Microsoft Lync Server 2013 environment includes:
• a single Standard Edition Server,
• a single consolidated Edge Server, and
• a single Forefront Threat Management Gateway 2010 server that is acting as an HTTP(S)
reverse proxy.
Client computers are configured as shown in the following table:

Some users report that they are unable to participate in audio/video conferences by using the Lync
Web App. You need to ensure that users are able to participate in audio/video conferences by using
the Lync Web App. Which two actions should you perform? (Each correct answer presents part of
the solution. Choose two.)

You support a customer whose network environment includes Microsoft Lync Server 2013 Standard
Edition. Your customer plans to enable sharing of Microsoft PowerPoint content in Lync meetings.
You enable the Office Web Apps Server discovery URL in the Lync Topology. You need to verify that
Lync Server 2013 enables PowerPoint content. What should you do?

You support a customer’s Microsoft Lync Server 2013 environment. Your customer has granted
User1 Conferencing Policy A, and User2 Conferencing Policy B. When User2 joins a video conference
that is hosted by User1, User2 sees only a single video window, while other users who are joined to
the same conference see up to five concurrent video streams. You need to configure the
environment to allow User2 to view multiple concurrent video streams. You need to achieve the goal
with the fewest changes to the environment. Which cmdlet should you run?

You support a customer whose Microsoft Lync Server 2013 environment consists of:
• A single Lync Server 2013 Standard Edition pool that is located in a main office, and
• Four branch offices that are connected by a 3MB dedicated wide area network (WAN) link,
each of which has 100 users.
Users in the branch offices report poor quality audio during conferences that are hosted on Lync.
The client has taken the following steps:
• Implement Quality of Service (QoS) and Call Admission Control (CAC).
• Provision policy-based QoS for your Lync media traffic.
• Enable CAC from the Lync Server 2013 Control Panel.
• Define the main office and each branch office as a site and associate its subnets.
• Poor audio quality persists.
You ask your customer to provide the output of running the Get-CsNetworkSite cmdlet.
The relevant portion of the results includes:

You need to improve the audio quality in your environment. What should you do?

You support a customer whose Microsoft Lync Server 2013 Enterprise environment that is
