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?

You support a customer whose network environment includes Microsoft Lync Server 2013 servers,
an Active Directory Domain Services (AD DS) domain, and Microsoft Exchange 2010. All client
computers have Lync 2013 and Outlook 2010 installed. You deploy USB-tethered Lync Phone Edition
devices for a group of users. Users are able to access all dialing features, calendar, and contacts.
Users report that the Call Logs feature is unavailable for them. You need to make Call Logs available
to all users. What should you do?

You support a customer whose network environment includes Microsoft Lync Server 2013 deployed
at two sites. Each site has 1 Mbps of available bandwidth on a multiprotocol label switching (MPLS)
network. Lync-to-Lync calls are getting dropped, and voice quality is degraded using RT Audio WB
codec with 100 simultaneous calls. Call admission control (CAC) is not being used. You need to
ensure that the RT Audio WB codec is maintained for Lync voice communication without overallocating- What is the minimum amount of bandwidth you should specify for each site?

You support a customer whose network environment includes Microsoft Lync Server 2013 servers.
All of the company servers are located in the company datacenter. All users have Lync 2013 installed
on their local computers. You deploy a virtual desktop infrastructure (VDI) environment to a pilot
group of users. You install the Lync VDI plug-in and plug Lync compatible devices to the users’
computers. Users report that Lync 2013 fails intermittently when pairing with the Lync VDI plug-in.
You need to ensure reliable access to Lync 2013 for this pilot group of users. What should you do?

You support a customer whose network environment includes Microsoft Lync Server 2013. A user
reports that when he attempts to dial out to a public switched telephone network (PSTN) number,
he receives the following message: “Your organization does not support calling this number.” All
other users are able to call the same number. You verify that the user is able to dial other Lync users
in the network. You need to ensure that the user is able to dial out to PSTN numbers. What should
you do?

You support a customer whose company network contains Microsoft Lync Server 2013. The
company has four buildings on a single site. A user reports that when she calls users in another
building, the call quality is poor. You receive the Quality of Experience (QoE) report:

Which of the following values is outside acceptable limits?

You support a customer whose network environment includes Microsoft Lync Server 2013. Some
devices run Lync Phone Edition and others run Lync soft clients. Lync soft client users report that
they experience voice quality problems with other Lync soft client users. Lync Phone Edition users
are not affected. You need to prioritize voice traffic for Lync soft clients to match the default Quality
of Service (QoS) configuration of the Lync Phone Edition users. What should you do?

You are a member of the CsAdministrator group that supports the Microsoft Lync datacenter for
your company. The datacenter consists of one pool that is running Microsoft Lync Server 2013. You
deploy a managed response group. The agent participation policy is set to Formal and the routing
method is set to Longest Idle. All agents have been logged in for more than four hours. On average,
each agent responds to five calls per hour. One agent has not received any calls. All of the other
agents have received calls. You need to ensure that all agents can receive calls through Response
Groups. What should you do?

DRAG DROP
You support a customer who is deploying Microsoft Lync Server 2013. The customer has completed
deployment of the following components:
• A Lync Standard Edition Server,
• A Lync Edge Server,
• A media gateway connected to a Tl trunk,
• Appropriate rules for reverse proxy, and
• An Office Web App server with Microsoft SharePoint 2012.
Neither federation nor external access is enabled.
The customer installs a number of Lync 2013 clients on pilot user computers that are located inside
their network. No one is able to access the Lync server from outside the network.
The pilot users report the following issues:
• When they make calls to local numbers, the calls do not work. An announcement states that
they must not dial 1 to make a local call.
• When they make calls to long distance numbers, the calls connect, but the other end user
reports that the caller’s number does not appear correctly.
• When they receive long distance calls from outside, the caller ID information displayed in
Lync does not match the caller’s contact information.
You need to ensure that users in the customer’s network can successfully have calls with users
outside the network. You open the Voice Routing tab on the Lync Server Control Panel as shown in
the exhibit. (Click the Exhibit button.)

Which area should you look in to investigate each issue? (To answer, drag the appropriate voice
routing area to the correct issue investigation or investigations. Each voice routing area may be used
once or not at all. You may need to drag the split bar between panes or scroll to view content.)

You support a customer whose network environment includes Microsoft Lync Server 2013 Standard
deployed with an Edge Server that is connected to the Internet. All users have Lync Mobile installed
on their Windows mobile devices. Users report that they receive instant messages only when the
Lync Mobile app is active in the foreground. You need to ensure that mobile users are able to receive
instant messages at all times. Which two actions should you perform? (Each correct answer presents
part of the solution. Choose two.)
