To answer, select the appropriate number of servers for each network in the answer area.
Hot Area:
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

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)

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.
