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

You run the Get-CsManagementStoreReplicationStatus cmdlet and discover the following replication issue:

From Telnet, you verify that you can connect to Lync3 over TCP ports 443, 4443, 5061, and 5062. You republish the topology successfully and you restart Lync3.
You need to identify what is causing the replication issue.
What should you identify?

You deploy a Lync Server 2013 infrastructure that contains four servers. The servers are configured as shown in the following table.

You need to deploy a Persistent Chat pool. The solution must use the least amount of servers.
On which server should you install the Persistent Chat Server role?

Your company has a main office and a branch office. The main office has 3,000 users. The branch office has 100 users. The offices are connected via a WAN link.
You have a Lync Server 2013 infrastructure. The main office has a pool named Pool1 that contains two Enterprise Edition Front End Servers. The branch office only
contains an Active Directory domain controller and a file server.
You need to recommend a high-availability solution to ensure that users can establish calls if one of the following components fails:
A Front End Server
A PSTN gateway
A WAN router
The solution must minimize deployment and maintenance costs.
What should you recommend?

You have a Lync Server 2013 infrastructure.
Your company has a sales department and a research department.
You deploy persistent chat.
You need to configure persistent chat to meet the following requirements:
Users in the sales department must be prevented from viewing the names of the rooms used by the research department.
Users in the research department must be able to discover all of the rooms used by their department.
What should you do?

You have a Lync Server 2010 infrastructure.
You plan to migrate to Lync Server 2013.
You have four client computers. The client computers are configured as shown in the following table.

You need to identify which client computer types can use audio conferencing hosted on Lync Server 2013 without installing any additional software on the client
computers.

Which client computer types should you identify? (Each correct answer presents part of the solution. Choose all that apply.)

You are planning a Lync Server 2013 deployment.
You need to recommend which Lync Server 2013 components are required to meet the following requirements:
Presence, chat, and multiparty video conferencing features must be provided.
Quality of Experience (QoE) data and call detail recording (CDR) must be provided.
Lync Server services must be provided to internal users only.
Licensing costs must be minimized.

Which two components should you recommend? (Each correct answer presents part of the solution. Choose two.)

You plan to deploy a Lync Server 2013 infrastructure.
You plan to use a Microsoft SQL Server database mirror that has a witness.
A database administrator gives you a list of five servers that you can use for the deployment. The servers are configured as shown in the following table.

You need to identify which servers you must use for the SQL Server backend.
Which servers should you identify?

You plan to deploy Lync Server 2013.
Your company uses only certificates that are purchased from a third-party certification authority (CA).
The company uses the following domain names to generate email addresses for users:
Adatum.com
Contoso.com
Fabrikam.com
Wingtiptoys.com
You plan to configure simple URLs for the planned deployment.
You need to recommend which meeting URLs to use. The solution must minimize the cost of purchasing certificates.
Which names should you include in the recommendation?

Your company has a main office and a branch office. The main office is located in Amsterdam. The branch office is located in New York. Each office has a data
center. The offices connect to each other by using a high-bandwidth, low-latency WAN link. You have a Lync Server 2013 infrastructure that contains 5,000 users.
You plan to deploy a persistent chat infrastructure.
You need to ensure that persistent chat rooms remain available if a Persistent Chat Server fails.
What should you do?

You have a Lync Server 2013 infrastructure that contains an Enterprise Edition front end pool.
You plan to add the following server roles to the existing infrastructure:
Edge Server
Archiving Server
Monitoring Server
Persistent Chat Server
You need to identify the minimum number of Microsoft SQL Server servers that must be added to the existing Lync Server 2013 infrastructure. The solution must
not use the existing SQL Server Back End Server.
What is the minimum number of SQL Server servers that you should identify?
