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. The trace log of failed sign-in attempt is as follows: INFO :: QueryDNSSrv -DNS Name[_sipinternaltls._tcp.contoso.com]ERROR :: HRESULT failed: 80072726 = HRESULT_FROM_WIN32(::ShimWSAGetLastError()) .

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: PoolA192.168.1.10PoolA192.168.1.11
• B. Create the following service record: _sipinternal._tls.contoso.com SRVPriority 0, weight 0, port 5061, FrontEndServer1.contoso.com
