You support a customer’s Microsoft Lync Server 2013 environment. Users regularly host online
meetings in which participants use the MultiView video feature in Lync Server 2013. All clients use
the Lync 2013 client and are located in the headquarters site as well as a branch site. The network
team reports high bandwidth utilization by Lync for these conferences. You need to find a potential
cause of the high bandwidth use. Which cmdlet should you run from the Lync Server Management
Shell?

You support a Microsoft Lync Server 2013 environment that consists of one Enterprise pool on a
Front End Server. Internal and external users cannot join online meetings using the Lync 2013 Lync
Web App. The same users are able to join online meetings by using the Lync 2013 client. You need to
diagnose the cause of the meeting join issues. Which cmdlet should you run from the Lync Server
Management Shell?

You support a customer whose Microsoft Lync Server 2013 Enterprise Pool is configured with
Enterprise Voice and Dial-in Conferencing. All client computers run Windows 7 or Windows 8. Many
users dial in to conferences and share Microsoft PowerPoint presentations. The server that hosts the
conferencing pool is experiencing technical difficulties that are causing conferences to fail. You
create a new Lync server and migrate users to this pool. You need to ensure that dial-in conference
Uniform Resource Identifier (URI) addresses are maintained. Which cmdlet should you run?

You support a customer whose network environment includes a Microsoft Lync Server 2013
Enterprise Pool that is configured with Enterprise Voice and Dial-in Conferencing. All client
computers run Windows 7 or Windows 8. You configure the following group policies to apply Quality
of Service (QoS) for audio and video to the organizational unit (OU) that contains the Lync 2013
Conferencing servers:
• Audio: DSCP port 46 and port range: 57000:59152
• Video: DSCP port 34 and port range: 60501:65535
You need to create a QoS for Application Sharing.

You support a customer whose network environment includes Microsoft Lync Server 2013 Standard
deployed with an Edge Server that is connected to the Internet. Your customer currently has Lync
Online configured for Hybrid mode with Office 365. You need to help your customer enable the
Office Web Apps Server for users who are using on-premise Lync. What should you do?

You support a Microsoft Lync Server 2013 environment that 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.
Remote users report that the company logo isn’t being displayed alongside the text in their Online
Meeting invites. You need to find out why the logo is not being retrieved.
Which two actions should you perform? (Each correct answer presents a part of the solution. Choose
two.)

You deploy a Microsoft Lync Server 2013 Enterprise Pool that is configured with Enterprise Voice and
Dial-in Conferencing. All client computers run Windows 8. Users regularly use the Lync client to
demonstrate new programs. A user reports that she is unable to select any Windows Store app
program to demonstrate. You need to ensure that Lync users are able to demonstrate Windows
Store app programs. What should you do?

Your customer’s Microsoft Lync Server 2013 environment is configured according to the following:
• Firewalls block all traffic between user subnets.
• Security policy prohibits any changes to firewall rules between user subnets.
The customer reports that:
• Users can share their desktop with others on the same subnet.
• Users are unable to share their desktop between users on different subnets.
You need to ensure that users can share their desktops between subnets.
What should you do?

You support a customer whose network environment includes a Microsoft Lync Server 2013
Enterprise Pool configured with Enterprise Voice and dial-in conferencing. All servers run Windows
Server 2012, and all client computers run Windows 7 64-bit. All users dial in to conferences. Users
report that dial-in conferencing settings are not consistent between sites, and that this is affecting
their conferencing experience. You need to ensure that dial-in conferencing settings are consistent
between all Lync sites. What should you do?

Your customer’s company has a main office and five branch offices located in different cities. Your
customer has a Microsoft Lync Server 2013 datacenter configured with Enterprise Voice at the main
office. The customer has deployed a Survivable Branch Appliance (SBA) at the first branch office and
connected it to a public switched telephone network (PSTN) by using a Tl trunk line provided by your
service provider. The gateway is configured to use fully qualified domain names (FQDNs). All
functionality has been tested by using pilot users at the branch office. The customer reports that
they tested branch isolation by disconnecting the wide area network (WAN) from their branch office
and making an outbound call. The call was successful. Next, they made an inbound call to the branch
office and the call failed. To troubleshoot the issue, you begin a trace of IncomingAndOutgoingCalls
by using centralized logging, and make an inbound call. You open the log in snooper and search for
incoming calls with the phone number from which you are calling. You do not find any messages.
You open the syslog from the gateway side of the SBA and discover that messages are sent to the
Lync Mediation server pool, but no responses have been received. You connect the WAN from the
branch office and make an inbound call. The call is successful. Your investigation suggests that there
is a configuration error on the Gateway side of the SBA. You need to identify the configuration error
that causes inbound calls to fail. What should you check?
