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 Iyncfe02. Currently, the Central Management store is hosted on lyncfe01.
A hardware failure occurs on Lynfe01.
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 -BackupSqIServerFQDN Iyncfe01.contoso.com BackupSqllnstanceName RTC -Force
C. Install CSDatabase -CentralManagementDatabase -SqIServerFqdn Iyncfe01.contoso.com -SQLInstanceName RTC -Clean
D. Invoke-CsPoolFailback -PoolFQDN Iyncfe01.contoso.com
E. Move-CsManagementServer
Correct Answer: CDE
Explanation/Reference:
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.
* Install CSDatabase
Install CSDatabase.
* 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.
Reference: To use Windows PowerShell cmdlets to configure the SQL Server Central Management store
