Explanation

Cisco IM and Presence supports two federation protocols for communicating with external domains: XMPP (Extensible Messaging and Presence Protocol) and SIP (Session Initiation Protocol). XMPP federation (Option A) allows IM&P to federate with other XMPP-based systems such as Google Talk or other Cisco IM&P deployments, enabling cross-domain instant messaging and presence. SIP federation (Option C) allows IM&P to federate with Microsoft Office Communications Server/Lync/Skype for Business or other SIP-based presence servers. SNMP (Option B) is a network management protocol, SCCP (Option D) is a Cisco phone signaling protocol, and SMPP (Option E) is a telecom short message protocol - none of these are used for IM&P federation.
