-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. Which three steps should you perform in sequence? (To answer, move the appropriate three actions from the list of actions to the answer area and arrange them in the correct order.)

Question 2

Your network environment includes Microsoft Lync Server 2013 with Enterprise Voice enabled. The current Lync Voice Configuration settings include the following: When users attempt to call to an outside number, they receive the following error: "User is not authorized." You need to ensure that users are able to dial outside numbers. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A. Under Dial Plan, modify normalization rule NA Long Distance from ^ (l\d{11}$ => +$11 to ^ (1\d{10}$ => +$1.
B. Modify public switched telephone network (PSTN) usage record NorthAmerica- PSTN and its associated route PSTN for voice policy from ^\+(?!(61)) to ^\+l\d{10}$.
C. Under Dial Plan, modify normalization rule Local from ^l?((403)\d{7})$ => +1$1 to ^(3\d{7})$ => +403$1.
D. Modify route NorthAmerica-LongDistance-from ^\+1\d{10>S to ^\ + l\d-{11}$.

Question 3

You support Microsoft Lync Server 2013 servers in your customer's company network. The network includes an Active Directory Domain Services (AD DS) domain and an Exchange 2010 organization. The company deployed a pilot Microsoft Exchange 2013 installation at one of its branches and moved the branch users' mailboxes to Exchange 2013. Lync users from the branch were configured to use the Unified Contact Store. Due to budget limitations, the company has decided to move the users' mailboxes back to Exchange 2010. Before you move the users' mailboxes, you need to change the users' properties. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A. Run the Test-CsUnifiedContactStore cmdlet once.
B. Run the Set-CsUserServicesPolicy cmdlet once.
C. Run the Move-CsUser cmdlet for every user account.

Question 4

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.)

A. Enable backup Registrar discovery by configuring Dynamic Host Configuration Protocol (DHCP) option 60 on the branch site's DHCP server.
B. Enable backup Registrar discovery by configuring Dynamic Host Configuration Protocol (DHCP) option 120 on the branch site's DHCP server to point to the fully qualified domain name (FQDN) of the SBA or SBS.
C. Enable backup Registrar discovery by configuring the SBA or SBS to respond to Dynamic Host Configuration Protocol (DHCP) 120 queries.
D. Enable backup Registrar discovery by configuring Dynamic Host Configuration Protocol (DHCP) option 55 on the branch site's DHCP server.

Question 5

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?

A. Route settings of the gateway
B. The domain controller at the branch office
C. DNS settings on the gateway
D. Dynamic Host Configuration Protocol (DHCP) options on the branch DHCP server
