Correct Answer:

Explanation/Reference: From the case:
"High Availability Requirements
The new Lync Server 2013 infrastructure in the New York office must be available if a
single server fails."
The Lync 2013 Infrastructure in New York consist of:
External Network: Edge Server
External Network: Reverse Proxy Server
Internal Network: Front-End & Persistent Chat Servers
So according to the above Lync 2013 Infrastructure to fill full High-Availability
requirements for continuity of Service even if one Server fails the following
Server configuration should be in place:
The answer:
2 Lync Servers on External Network (Role: Edge Server)
4 Lync Servers on Internal Network (Roles: 2 Front-End Servers, 2 Persistent Chat Servers)
2 Lync Servers on External Network (Role: Reversed Proxy Server)
0 Lync Servers on Internal Network (Roles: Reversed Proxy Server)

Correct Answer:

Explanation:

Detailed Description
When an administrator makes a change of some kind to Lync Server (for example, when an administrator
creates a new voice policy
or changes the Address Book Server configuration settings) that change is recorded in the Central
Management store.
In turn, the change must then be replicated to all the computers running Lync Server services or server
roles.
In order to replicate data, the Master Replicator (running on the Central Management Server) creates a
snapshot of the modified configuration data;
a copy of this snapshot is then sent to each computer running Lync Server services or server roles.
On those computers, a replication agent receives the snapshot and uploads the modified data;
the agent then sends the Master Replicator a message reporting the latest replication status.
The Get-CsManagementStoreReplicationStatus cmdlet enables you to verify the replication status for any (or all) of the Lync Server computers in your organization.
Who can run this cmdlet:
By default, members of the following groups are authorized to run the Get-
CsManagementStoreReplicationStatus cmdlet locally:
RTCUniversalUserAdmins,
RTCUniversalServerAdmins.
To return a list of all the Role-Based Access Control (RBAC) roles this cmdlet has been assigned to (including any custom RBAC Roles you have created yourself), run the following command from the Windows PowerShell prompt:
Get-CsAdminRole | Where-Object {$_.Cmdlets -match "Get-
CsManagementStoreReplicationStatus"}

Correct Answer:

Explanation: Decommission Legacy Site:
The following topics provide guidance in Decommissioning Pools, and Deactivating and Removing Servers
and Pools from a Legacy Deployment of Office Communications Server 2007 R2.
Not all of the procedures listed in this section are required.
Read the information in each of these topics to determine which decommissioning procedure to use.
Caution:
If you imported Conference Directories for Dial-In Conferencing to Lync Server 2010,
it is Important to Transition Conference Directory Ownership to Lync Server 2010 before you begin to
Decommission your Pools.
If you Decommission a Pool without first Transition Conference Directory Ownership,
the Dial-In Feature for all Migrated Meetings will no longer work.
You must perform the step to Transition Ownership once for each Conference Directory in your Legacy
Pool.
