HOTSPOT
You support Microsoft Lync Server 2013 servers in your customer’s company network. You plan to
configure Extensible Messaging and Presence Protocol (XMPP) federation with an instant messaging
partner.

You support Microsoft Lync Server 2013 servers in your customer’s company network. The Lync
topology includes one site named HQ, with two servers named LyncFE.contoso.com and
LyncDir.contoso.com. The servers use Kerberos authentication for web services. The Kerberos
authentication account name is contoso\kerberos. The account has been accidentally deleted from
the Active Directory Domain Services (AD DS) database. Users are unable to sign in to Lync. You need
to restore Kerberos authentication. You remove Kerberos assignment for the missing account and
enable the topology. In which order should you perform the next actions? (To answer, move all
actions from the list of actions to the answer area and arrange them in the correct order.)

You support a customer whose network environment includes Microsoft Lync Server 2013
Enterprise, with two Front End Servers and two Back End Servers. The Back End Servers are deployed
in a high availability configuration. You create a Front End pool named pool.contoso.com and
implement DNS load balancing for client access to the Lync servers. Your internal DNS records have

You support a customer who is upgrading from Lync 2010 Group Chat to Lync 2013 Persistent Chat.
Users are Session Initiation Protocol (SIP) enabled members of a single Active Directory Domain
Services (AD DS) domain. Group Chat clients connect by using a well-known user named
ocschat@litwareinc.com. The Lookup service registers with the Lync server to receive incoming
requests. Your customer’s Persistent Chat pool fully qualified domain name (FQDN) is named
pchatpool.litwareinc.com. When users sign out of Lync and then sign in again by using the Lync 2010
Group Chat client, they are able to access their data without needing to change any configuration.

You need to configure Lync Server 2013 persistent chat to support legacy Group Chat clients. Which
cmdlet should you run?

You support a customer whose network environment includes Microsoft Lync Server 2013. The
Global client policy is set up for web search and file download. Each department within the company
is on its own subnet. The switches are configured with Access Control Lists (ACL) that are limiting
access to other subnets, including the one on which the Lync 2013 servers reside. Users in the
company’s accounting department report that new internal users are not showing up in their Lync
2013 searches. These users are internal, and there are no Lync Director servers deployed. You need
to ensure that users in the accounting department are able to find new users when they search the
Lync address book. What should you do?

presence information in Lync 2013 is not updated based on his Calendar. You need to ensure that
the user’s presence information is updated based on his Calendar. What should you do?
