Your network contains an internal network and a perimeter network.
The networks are separated by a firewall. The internal network contains a Central Management Server.
The perimeter network contains an Edge Server. You discover that changes to the Central Management Store (CMS) do not replicate to the Edge Server.
You need to ensure that all changes to the CMS replicate to the Edge Server.
Which protocol should you allow on the firewall?

Your network connects to the Internet by using a firewall. The perimeter network contains a Lync Server 2010 Edge Server. Some users work remotely.
You need to ensure that the remote users can sign in to Microsoft Lync 2010.
Which TCP port should you open on the firewall?

Your network contains an internal network and a perimeter network.
The networks are separated by a firewall. The internal network contains a Lync Server 2010 pool.
The perimeter network contains a Lync Server 2010 Edge pool.
You discover that updates to the Lync Server 2010 topology do not replicate to the Edge Servers.
You need to ensure that the Lync server replicates successfully to the Edge Servers.
Which port should you open on the firewall?

Your network connects to the Internet by using a server that runs Microsoft Forefront Threat Management Gateway (TMG).
The network has a Lync Server 2010 infrastructure that contains an Edge Server and a Front End Server.
All client computers run Microsoft Lync 2010. Some users work remotely.
Remote users report they are unable to expand distribution groups.
You verify that all of the users can initiate IM conversations.
You need to enable distribution group expansion for all users.
What should you do first?

Your network contains a SIP domain named contoso.com.
The network has a Lync Server 2010 infrastructure that contains an Edge pool.
You need to ensure that other Lync Server 2010 organizations on the Internet can automatically discover your Edge Servers for federation.
Which DNS records should you create?

Your network has Lync Server 2010 and Microsoft Office Communications Server 2007 R2 deployed.
The network contains an Edge Server that runs Office Communications Server 2007 R2.
Lync users report that they are unable to initiate IM conversations to federated contacts.
You verify that Office Communications Server 2007 R2 users can successfully initiate IM conversations to federated contacts.
You need to ensure that all Lync users can successfully communicate with the federated contacts.
Which two tasks should you perform? (Each correct answer presents part of the solution. Choose two.)

Your network has Lync Server 2010 deployed.
The network contains a server named Server1 that runs Windows Server 2008 R2.
Server1 is a member of a workgroup.
You need to deploy the Edge Server role on Server1.
What should you do first?

Your network contains an internal network and a perimeter network.
The perimeter network contains a server named Server1 that runs Windows Server 2008 R2.
Server1 is a member of a workgroup.
You plan to configure Server1 as a Lync Server 2010 Edge Server.
You need to prepare Server1 for the planned configuration.
What should you do on Server1?

Your network contains a SIP domain named contoso.com.
Contoso.com has Microsoft Office Communications Server 2007 deployed.
AU client computers run Windows XP Service Pack 2 (SP2) and Microsoft Office Communicator 2007.
You deploy Lync Server 2010 on the network.
You need to ensure that all of the client computers can log on to Lync Server 2010 after their accounts are moved to the new Lync pool.
What should you do?

Your network has Lync Server 2010 deployed.
You need to modify the Lync Server 2010 infrastructure to meet the following requirements:

+ Users must be prevented from creating conferences that have more than 20 invitees.
