You need to ensure that users are able to sign in to Lync from their mobile devices on a carrier network
You support a customer whose network environment includes Microsoft Lync Server 2013 Standard
deployed with an Edge Server that is connected to the Internet. Some users have Lync Mobile
installed on their mobile devices. When the users attempt to sign in to Lync from their mobile
devices on a carrier network, they receive the following error message: “Cannot connect to the
server. It might be unavailable. Also please check your network connection, sign-in address, and
server addresses.” You need to ensure that users are able to sign in to Lync from their mobile
devices on a carrier network. What should you do?
Which two ports should you open on the firewall?
You support a customer whose network environment includes Microsoft Lync Server 2013. A firewall
filters all inbound traffic from the Internet. All outbound IP traffic is permitted. Users report voice
quality problems when they attempt to communicate with external participants. You need to ensure
that Lync users are able to communicate with external participants. Which two ports should you
open on the firewall? (Each correct answer presents part of the solution. Choose two.)
You need to ensure that the LPE device can authenticate to EWS
You support a Microsoft Lync Server 2013 environment that includes:
• Two Enterprise consolidated Lync servers in a single pool,
• Two Edge consolidated Lync servers in a single pool,
• One Microsoft Office Web Apps server, and
• One reverse HTTP(S) proxy server.
Microsoft Exchange 2010/Microsoft Outlook 2013 are used for internal email and Unified Messaging.
The email solution has been used within the company for an extended time without any issues.
Unified Messaging has been configured and set up as part of the Lync 2013 implementation project.
You plan to deploy Enterprise Voice for all users, including users who have Lync Phone Edition (LPE)
devices that are connected by using a LAN cable and a USB cable. You begin migrating test accounts.
When a test user signs into Outlook 2013 and Lync 2013, all communications appear to be working
as expected. Outlook creates the user profile as expected and logs into the test user mailbox. The
test user signs into Lync as expected and is able to communicate with Exchange by using Exchange
Web Services (EWS). After the test user signs into Lync, a prompt is displayed requesting user
credentials for the Lync Phone Edition device. The test user enters his credentials and the phone
signs into Lync; however, after a short period of time, a yellow warning triangle appears on every
test LPE device. In reviewing the LPE device for errors, you discover that Exchange integration is
failing with the following error: “Connection to Microsoft Exchange is unavailable. Please contact
your support team.” Logs from the LPE Device are displayed in the Exhibit 1. (Click the Exhibit
button.)
Internet Information Services (IIS) logs on the Exchange Client Access server (CAS) are displayed in
Exhibit 2. (Click the Exhibit button.)
You need to ensure that the LPE device can authenticate to EWS. What should you do?
Which three steps should you perform in sequence?
DRAG DROP
You are helping your customer perform a side-by-side migration from Microsoft Lync Server 2010 to
Microsoft Lync Server 2013 Your customer’s Lync environment currently includes the following:
• Lync Server 2010 Pool with two Enterprise Edition Front End servers
• Lync Server 2010 Mediation Server pool with one Mediation Server
• Lync Server 2010 Edge pool with one Edge Server
• Lync Server 2010 Audio/Video (A/V) pool with two A/V Servers
• Lync Server 2010 Monitoring and Archiving Server
• Lync Server 2013 Pool with three Enterprise Edition Front End servers and collocated
Mediation Server pool
• Lync Server 2013 Persistent Chat server pool with two servers
• Lync Server 2013 Edge Server pool with two servers
• Two Session Initiation Protocol (SIP) trunks connected to Lync Server 2010 Mediation Server
• Two SIP trunks connected to Lync Server 2013 Front End Pool Mediation server pool
Your customer moves a batch of users to Lync Server 2013. One user reports that when she
escalates the IM conversation to an Audio/ Video conference with her colleague who is on Lync
Server 2010, audio and video quality become choppy. She also reports that the bars change from
green to orange to red. Users who are on Lync Server 2010 do not report any problems with audio or
video quality. The Lync Server 2013 user reports that after a few minutes, everything starts working
fine. You discover that the Lync 2013 user is using a home Wi-Fi connection. You start a Lync 2010
client on a test computer and sign in with a Lync Server 2010 test user account. You start a Lync 2013
client on a second test computer and sign in with a Lync Server 2013 test user account. You re-create
the problem by using two test user accounts and collect the following information:
• log file from each client
• Lync events from each client
• log files from both Front End Server pools
• Lync Server event from Lync Server 2013 pool
• Network Monitor data on Edge Server
• Network Monitor data on the test computer that has Lync 2013
You need to analyze the logs and packet data to diagnose the problem.

You need to ensure that users are able to receive calendar information from Lync Mobile devices
You support a customer who administers Microsoft Lync Server 2013 Enterprise servers in his
company. The pool named lync.contoso.com is configured with the session initiation protocol (SIP)
domain contoso.com.
Users who are running Lync Mobile on their mobile devices report that when they attempt to
retrieve calendar information, they receive an error that references a Microsoft Exchange Web
Services connectivity issue. You need to ensure that users are able to receive calendar information
from Lync Mobile devices. What should you do?
Which PowerShell cmdlet should you use with each parameter?
DRAG DROP
You support a customer whose network environment includes Microsoft Lync Server 2013. Your
environment is connected to a third-party network that is supported as a peer IP Private Branch
Exchange (PBX) by using direct Session Initiation Protocol (SIP). Both environments are configured
properly, and call routing is functional within the two domains. Media Bypass is configured.
Protocols used to specify quality of service (QoS) feedback, synchronization between media streams,
and Secure Real-time Transport Protocol (SRTP) are not supported. Users report that they
experience poor audio quality when calling public switched telephone network (PSTN) numbers. You
need to improve call quality when calling PSTN numbers. Which PowerShell cmdlet should you use
with each parameter? (To answer, drag the appropriate cmdlet to the correct parameter or
parameters. Each cmdlet 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.)
What minimum required dedicated bandwidth should you allocate?
You support Microsoft Lync Server 2013 servers in your customer’s network. The network includes
two branches connected with a 10Mbps network circuit. The circuit has 2 Mbps of dedicated
bandwidth for Lync voice traffic. RT Audio WB codec with 50 simultaneous calls is used. Users report
that calls between the branches are being dropped, and voice quality is degraded. You need to
calculate a bandwidth for the RT Audio WB codec. What minimum required dedicated bandwidth
should you allocate?
What are two possible ways to achieve this goal?
You support a datacenter that runs Microsoft Lync Server 2013 with Enterprise Voice (EV). The
company has opened two new satellite branches and configured one with a Survivable Branch
Appliance (SBA) and the other with a Survivable Branch Server (SBS). Neither branch has a DNS
server. A wide area network (WAN) outage occurs and EV stopped working for the branch users. You
need to ensure that EV functionality continues in the event of WAN outages. What are two possible
ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
