A. B. C. D. E. F.ACD.
Please refer to the link for more information: http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cups/8_6/english/integration_notes/Federation/ Intradomain_Federation/Partitioned_Intradomain_Federation/InterdomainFederation.html.
Partitioned intradomain federation allows for real-time communication and presence sharing between two different communication systems within the same organization. In this case, the federation is being configured between Cisco Unified Communications Manager (CUCM) and Microsoft Lync.
A. The first statement that is true is that intradomain federation to Lync is only possible using SIP. Session Initiation Protocol (SIP) is the standard protocol used for initiating, maintaining, and terminating real-time communication sessions between two or more endpoints. Therefore, SIP is the only protocol that can be used to establish a federation between CUCM and Lync.
B. The second statement that is true is that IM&P and Lync should federate to any required remote domains. Remote domains refer to other organizations that also use Lync or another compatible communication system. To communicate with these remote domains, both IM&P and Lync must establish federations to those domains.
C. The third statement that is true is that you must update the URIs of any users migrated from Lync to IM&P to match the Cisco Unified Presence Server SIP URI format. User Resource Identifiers (URIs) are unique identifiers used to represent users in a communication system. To ensure proper communication and presence sharing between the two systems, the URIs of users migrated from Lync to IM&P must be in the correct format.
D. The statement that is not true is that a static route must be added to point the local presence domain to the Lync server. Static routes are used to direct traffic between different networks. However, in this case, the local presence domain refers to the domain in which the CUCM and IM&P servers reside. The local presence domain does not need a static route to reach the Lync server since both servers are within the same organization.
E. The statement that is not true is that Microsoft RCC must be enabled. Remote Call Control (RCC) is a legacy feature that allows a user to control their desk phone from their computer. However, it is not required for intradomain federation between CUCM and Lync.
F. The final statement that is true is that the Enable use of Email Address when Federating option can be turned on if SIP URIs are different between IM&P and Lync. If the SIP URIs used by users in CUCM and Lync are different, the Enable use of Email Address when Federating option can be turned on to allow communication and presence sharing between the two systems using email addresses instead of SIP URIs.
