You support a customer whose network environment includes Microsoft Lync Server 2013 Enterprise, with two Front End Servers and two Back End Servers. The Back End Servers are deployed in a high availability configuration. You create a Front End pool named pool.contoso.com and implement DNS load balancing for client access to the Lync servers. Your internal DNS records have the following configuration: _gc._tcp.contoso.com SRV priority 0, weight 100, port 3268 dc1.contoso.com_ldap._tcp.contos.com SRV priority 0, weight 100, port 389 dc1.contoso.com_kerberos._tcp.contos.com SRV priority 0, weight 100, port 88 dc1.contoso.com_sip._tls.contoso.com SRV priority 0, weight 0, port 5061, pool.contoso.com FrontEndServer1 A 192.168.1.10FrontEndServer2 A 192.168.1.11BackEndServer1 A 192.168.1.20BackEndServer2 A 192.168.1.21Pool01 A 192.168.1.10Pool01 A
192.168.1.11 Your Lync 2013 clients fail to sign in automatically.

You also need to ensure that internal traffic is load balanced across the two Front End Servers. What should you do?

• A. Create the following host records: SipA 192.168.1.20SipA 192.168.1.21
• B. Create the following host records: PoolA192.168.1.10PoolA192.168.1.11
• C. Create the following service record: _sip._tls.contoso.com SRVPriority 0, weight 0, port 5061, pool01.contoso.com

DRAG DROP You support Microsoft Lync Server 2013 servers for an international company. You enable the Enhanced 9-1-1 (E9-1-1) emergency notification feature for users in a New York office. The users report that Lync prompts them to enter a location. You need to configure Lync to populate location information automatically. 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.

Explanation:
Box 1: Set the Location Required policy to Disclaimer.
Box 2: Populate the location database.
Box 3: Publish the location database.
Note:
*To enable clients to automatically detect their location within a network, you first need to configure the location database. If you do not configure a location database, and Location Required in the location policy is set to Yes or Disclaimer, the user will be prompted to manually enter a location. To configure the location database, you will perform the following tasks:
*To automatically locate clients within a network, you first need to populate the location database with a network wiremap, which maps network elements to civic (that is, street) addresses. You can use subnets, wireless access points, switches, and ports to define the wiremap. You can add addresses to the location database individually, or in bulk by using a CSV file that contains the column formats described in the following table. Reference: Configure the Location Database

You support a customer whose network environment includes Microsoft Lync Server 2010 Group Chat. You plan to deploy Microsoft
Lync Server 2013 Persistent Chat. You need to ensure that users who access Group Chat will have access to their chat history in Persistent Chat. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Ensure that legacy clients can connect to the new Persistent Chat pool. Shut down the Persistent Chat Services, and then run the Import-CsPersistentChatData cmdlet.
• B. Back up the mgc from the Group Chat server and restore it to the Persistent Chat server.
• C. Run the Set-CsPersistentChatActiveServer cmdlet.
• D. Deploy Lync Server 2013, and then deploy a Persistent Chat pool. Shut down the Lync Server 2010 Group Chat Services, and then run the Export- CsPersistentChatData cmdle:.

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?

• A. Add an Exchange Autodiscover SRV record to the company DNS servers.
• B. Configure Lync Phone Edition devices to use only client certificate authentication.
• C. Configure the Lync Phone Edition devices to use only PIN authentication.
• D. Add the Exchange Unified Messaging server role to the Exchange organization.

You support a Microsoft Lync Server 2013 environment.
The network includes:
-An Enterprise Edition Front End Pool with two Front End Servers,
-A mediation server that is collocated on the Front End Server, and
-A media gateway with 4 Tl trunks for public switched telephone network (PSTN) connectivity.
Users report intermittent outbound PSTN call failures. There are no issues with inbound PSTN
calls. You view the event log information as shown in the exhibit. (Click the Exhibit button.)

You need to find out why outbound calls are failing.
Which two event IDs should you investigate? (Each correct answer presents a complete solution. Choose two.)

• A. 46027
• B. 46009
• C. 44009
