Which two protocols are used in Cisco Jabber call control signaling and instant messaging? (Choose two)

XMPP (Extensible Messaging and Presence Protocol) is the native protocol used by Cisco Jabber to communicate with Cisco IM and Presence Service for instant messaging and presence status exchange.

TCP is a transport-layer protocol that carries application data; while Jabber uses TCP as an underlying transport, TCP itself is not a call control or instant messaging signaling protocol.

SIP/SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions) is used by Cisco Jabber for call control signaling to CUCM and for presence and messaging federation with other SIP-based systems.

SSH is a secure remote administration protocol and plays no role in Cisco Jabber call control signaling or instant messaging functions.

SCCP is a Cisco-proprietary protocol used by legacy IP desk phones for call signaling; Cisco Jabber relies on SIP for call control, not SCCP.
