You support a customer whose network environment includes Microsoft Lync Server 2013 Enterprise
Voice deployed at two sites named Sitel and 5ite2. All users require extension dialing. Only direct
inward dialing will be used for auto attendants or response groups. The extension numbers in fourdigit format are stored in the telephoneNumber attribute on the users’ Active Directory Domain
Services (AD DS) account. Sitel uses 2xxx extensions, and Site2 uses 3xxx extensions. You want to
retain the four-digit extensions in Active Directory, but also present the numbers as valid numbers in
the Lync 2013 client. You need to ensure that four-digit dialing normalizes properly in the address
book for Lync. What should you do?

users’ mailboxes back to Exchange 2010. Before you move the users’ mailboxes, you need to change
the users’ properties. Which two actions should you perform? (Each correct answer presents part of
the solution. Choose two.)

You support a customer whose network environment includes Microsoft Exchange 2010 and
Microsoft Lync Server 2010servers. Outlook Web Access (OWA) is configured to display presence
from Lync. Your customer recently migrated users and servers to a Microsoft Lync Server 2013
environment. Users report that presence is no longer available in OWA. You need to restore

You support a Microsoft Lync 2013 environment in your customer’s network. A single front-end
Microsoft Lync Server 2013 server is configured to support a session initiation protocol (SIP) domain
named proseware.net. All computers in the network are members of an Active Directory Domain
Services (AD DS) domain named proseware.local. You configure Lync to support users from a new SIP
domain named contoso.net. The users of the contoso.net SIP domain report that their Lync client is
able to connect to the Lync server only after manual configuration. Users of the proseware.com SIP
domain are able to connect to Lync server automatically, both internally and externally. You need to
enable the internal and external automatic discovery features for the users of the new contoso.net
SIP domain. Which fully qualified domain name (FQDN) should you add to the subject alternative
name (SAN) in each certificate request? (To answer, drag the appropriate FQDN to the correct

Server 2013 enhanced presence privacy mode is enabled. A user reports that her presence and
contact information is accessible to users who have not been authorized to view it. You need to
prevent unauthorized users from accessing the user personal information. Which three actions
