Q36. - (Topic 6) 

You have a Lync Server 2013 infrastructure. The infrastructure contains two servers. The servers are configured as shown in the following table. 

Pool pairing is configured between lyncfe01 and lyncfe02. Currently, the Central Management store is hosted on lyncfe01. 

A hardware failure occurs on Lyncfe01. 

You manually perform a failover of all the user services and the Central Management store to Lyncfe02. 

You resolve the hardware issue on Lyncfe01. 

You need to restore all of the user services and the Central Management store to Lyncfe01. 

Which three commands should you run? (Each correct answer presents part of the solution. Choose three.) 

A. Invoke-CsPoolFailback -PoolFQDN Iyncfe02.contoso.com 

B. Invoke-CsManagementServerFailover -BackupSqlServerFQDN lyncfe01.contoso.com BackupSqllnstanceName RTC -Force 

C. Install CSDatabase -CentralManagementDatabase -SqlServerFqdn lyncfe01.contoso.com -SQLInstanceName RTC -Clean 

D. Invoke-CsPoolFailback -PoolFQDN lyncfe01.contoso.com 

E. Move-CsManagementServer 

Answer: C,D,E 

Explanation: The pool named lyncfe01.contoso.com is the pool that failed over to LyncFE02 when LyncFE01 failed. Therefore, we need to fail back pool lyncfe01.contoso.com to the recovered server.

 Lync Server makes extensive use of SQL Server databases, ranging from the Central Management store to the Archiving database. As a general rule, these databases are set up at the same time you install Lync Server or at the same time you install a Lync Server role (such as Monitoring Server) that requires a database back end. After installation has taken place these databases typically will not need to be reinstalled or moved to new locations. On rare occasions, however, you might need to manually install a Lync Server database; this could be because you need to move a database to another server, or because a setup-related problem failed to install the database for you. The Install-CsDatabase cmdlet provides a way for you to install any of the SQL Server databases used by Lync Server. 

*

 Invoke-CsPoolFailback Invokes the failback process for a Lync Server 2013 pool. Failback is used after a pool has failed over and the users of that pool have been "failed over" to a backup pool. (That simply means users who were signed on to the failed pool are automatically signed on to the backup pool.) When the failed pool has been restored, the fail back process signs the failed-over users back to their original pool. *Move-CsManagementServer Moves the Central Management Server from one pool to another.

each Mediation Server. The solution must meet the Enterprise Voice requirements. 

How many ports should you identify? 

To answer, configure the appropriate number of network ports for the component in the 

answer area. 

A. 1 

B. 2 

C. 3 

D. 4 

Answer:

Explanation: 

http://technet.microsoft.com/en-us/library/gg398399.aspx 

Note: The Mediation Server translates signaling and, in some configurations, media between your internal Lync Server 2013, Enterprise Voice infrastructure and a public switched telephone network (PSTN) gateway or a Session Initiation Protocol (SIP) trunk. On the Lync Server 2013 side, Mediation Server listens on a single mutual TLS (MTLS) transport address. On the gateway side, Mediation Server listens on all associated listening ports associated with trunks defined in the Topology document. All qualified gateways must support TLS, but can enable TCP as well. TCP is supported for gateways that do not support TLS. 

The main functions of the Mediation Server are as follows: . Encrypting and decrypting SRTP on the Lync Server side.. Translating SIP over TCP (for gateways that do not support TLS) to SIP over 

mutual TLS . Translating media streams between Lync Server and the gateway peer of the Mediation Server . Connecting clients that are outside the network to internal ICE components, which enable media traversal of NAT and firewalls . Acting as an intermediary for call flows that a gateway does not support, such as calls from remote workers on an Enterprise Voice client . In deployments that include SIP trunking, working with the SIP trunking service 

provider to provide PSTN support, which eliminates the need for a PSTN gateway The following figure shows the signaling and media protocols that are used by the Mediation Server when communicating with a basic PSTN gateway and the Enterprise Voice infrastructure.
