Microsoft Lync 2013 Depth Support Engineer Sample Questions:

1. 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?

A) Create a Group Policy with VoiceDiffServTag set to 0.
B) Create a Group Policy with VoiceDiffServTag set to 40.
C) Create a Group Policy with Voice 8021p set to 0.
D) Create a Group Policy with Voice 8021p set to 40.

2. You support a customer whose network environment includes Microsoft Lync Server 2013 Standard Edition. Your customer plans to enable sharing of Microsoft PowerPoint content in Lync meetings. You enable the Office Web Apps Server discovery URL in the Lync Topology. You need to verify that Lync Server 2013 enables PowerPoint content. What should you do?

A) Check the Event Log of the Front End pool server.
B) Verify the connection to the Office Web Apps Discovery URL in a web browser.
C) Check the Lync Server Control Panel.
D) Check the Event Log of the Office Web Apps server.

3. You support a Microsoft Lync Server 2013 Enterprise pool deployed in a high availability configuration for Back End Servers named Backend1 and Backend2. You execute the Get-CSDatabaseMirrorState cmdlet and discover the following errors. WARNING: Cannot connect to database server "BackEnd2.contoso.com".Message: A network- related or instance-specific error occurred whileestablishing a connection to SQL Server. The server was not found or was notaccessible. Verify that the instance name is correct and that SQL Server isconfigured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)DatabaseName : rtcabStateOnPrimary : PrincipalStateOnMirror : StatusUnavailableMirroringStatusOnPrimary :synchronizedMirroringStatusOnMirror :DatabaseName : rtcxdsStateOnPrimary : PrincipalStateOnMirror : StatusUnavailableMirroringStatusOnPrimary :synchronizedMirroringStatusOnMirror You need to resolve the connectivity issue and bring up the mirror databases to the synchronized state between the Back End Servers. What should you do?

A) Run the Invoke-CsPoolFailOver cmdlet.
B) Run the Test-CsDatabase cmdlet.
C) From the mirror Back End Server, create the inbound rule on the firewall.
D) From the Front End Server, create the inbound rule on the firewall.

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

5. 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()) . Failed to convert string IP to SOCKADDRERROR :: ResolveHostNameUsingGetAddrInfo getaddrinfo(pool.contoso.com) failed WARN :: ResolveHostName
-getaddrinfo failed for pool.contoso.com ERROR :: ResolveHostNameUsingDnsQuery - DnsQuery(pool.contoso.com) failed WARN :: ResolveHostName - DNS lookup failed for pool.contoso.com ERROR :: ResolveHostName - Name resolution for pool.contoso.com failedERROR :: ResolveHostSyncResolveHostName failed ERROR :: GetDnsResults - did not get any resultERROR :: QueryDNSSrvGetDnsResults query: _sipinternaltls._tcp.contoso.com failed ERROR :: DNS_RESOLUTION_WORKITEM::ProcessWorkItemResolveHostName failed You need to ensure that internal Lync 2013 clients can 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 service record: _sip._tls.contoso.com SRVPriority 0, weight 0, port 5061, pool01.contoso.com
B) Create the following host records: PoolA192.168.1.10PoolA192.168.1.11
C) Create the following service record: _sipinternal._tls.contoso.com SRVPriority 0, weight 0, port 5061, FrontEndServer1.contoso.com
D) Create the following host records:PoolA192.168.1.20PoolA192.168.1.21
E) Create the following host records: SipA 192.168.1.20SipA 192.168.1.21
